Recently, the United States government has made a bold move in promoting eco-friendly transportation. A groundbreaking bill was passed last Friday, offering up to $1500 in subsidies for citizens purchasing electric bicycles. This initiative marks a significant shift in the nation's approach to sustainable travel, aiming to reduce carbon emissions and encourage healthier lifestyles.
The subsidy beneficiaries of this bill also include buyers of electric motorcycles (two-wheelers and three-wheelers). The bill proposes to provide taxpayers who purchase electric motorcycles with a refundable tax credit equivalent to 30% of the purchase price of the new vehicle. For electric bicycles, the maximum discount is $1,500, while for electric motorcycles, the maximum discount is $7,500. This 30% subsidy is a first-time benefit for electric bicycles, while the previous discount for electric motorcycles was 10%.
Criteria for eligible electric motorcycles for the subsidy: The battery capacity should not be less than 2.5 kWh, and the speed should not be lower than 72 km/h.
The bill will also provide pre-tax commuting subsidies for individuals who commute to work on electric bicycles or shared bicycles. According to the proposal, the amount of the electric bicycle commuting subsidy will be 30% of the parking subsidy, which is equivalent to $81 per month or approximately $1,000 per year.
The eligibility criteria for the electric bicycle subsidy are as follows: electric bicycles with a purchase price lower than $8,000.
We know that the majority of electric bicycles in the US market are sourced from China. If this policy is implemented, it will undoubtedly be a significant boost for Chinese manufacturers. According to Yin Xinci, an analyst at CITIC Securities, since the electric two-wheelers available in the US are mainly e-bikes with prices ranging from $1,000 to $8,000, the smooth implementation of the new budget agreement will significantly reduce the cost for consumers, further promoting the overall development of the micro-electric vehicle industry. As the US lacks a mature micro-electric vehicle industry chain and heavily relies on imports, it is expected that this bill will directly drive the performance improvement of domestic related enterprises.
"The latest vote in the House of Representatives on the 'Build Back Better (BBB) Act' is part of a climate solution due to new financial incentives for bicycles and electric bicycles, as well as funding for improving climate-related infrastructure. We are urging the Senate to adopt the BBB Act by the end of the year so that we can benefit everyone, regardless of how they travel or where they live. We can make efforts to reduce carbon emissions."
According to The Verge, the agreement is currently in the final stages before approval, and there is a strong possibility that the policy will be implemented. In the coming weeks, the Senate may revise the agreement. Chuck Schumer, the Majority Leader of the Senate, stated that his goal is to have the Senate pass the bill before Christmas, which means that this $1.75 trillion spending plan could potentially be implemented as early as January next year.

The world of electric bicycles is rapidly gaining momentum, captivating cycling enthusiasts worldwide. These innovative vehicles offer a plethora of advantages over conventional pedal bikes, revolutionizing the way we ride. However, amidst this growing trend, many riders find themselves grappling with questions about their e-bike's battery and its optimal charging routine.
One recurring query revolves around the frequency of charging an e-bike battery. Is it best to wait until the battery is completely drained or should you avoid it altogether? The answer lies in the electric bike's built-in battery indicator, which simplifies the charging process for riders. By heeding the indicator's suggestion, you can ensure optimal battery performance and longevity.
An e-bike battery is typically discharged when it reaches its maximum range, indicating the farthest distance it can cover on a single charge. This range varies depending on the e-bike model, with some offering only pedal-assist mode while others boast a throttle mode for effortless propulsion. Additionally, the level of assistance provided by the motor significantly affects the achievable range, even without utilizing the throttle mode.
Most electric bicycles offer a range of 22 to 50 miles, though certain models can surpass these limits. These estimates are based on relaxed pedaling. However, with consistent pedaling and a high-quality e-bike, you can extend the range to approximately 80 miles, unlocking a world of possibilities.
While the battery's capacity plays a crucial role in charging frequency, other factors also impact the range:
Battery Capacity: The battery's capacity determines the frequency of charging, with higher capacity batteries requiring less frequent charges.
Terrain Type: Uphill journeys necessitate increased motor assistance, drawing more current from the battery and reducing the range. Similarly, riding against strong headwinds mimics uphill terrains, albeit on a smaller scale.
Rider's Weight: Heavier riders demand more power from the motor, resulting in increased electric current consumption from the battery.
On the other hand, descending hills or utilizing minimal assistance on flat terrain can conserve battery power. But should you deplete the battery entirely during every ride?
To maximize battery life, it is advisable to avoid frequent full discharges. Instead, aim to charge the battery when it reaches around 30% capacity and alternate between charging at 30% and 60% remaining capacity. This alternating charging pattern helps preserve the longevity of lithium-ion batteries commonly found in e-bikes. However, a complete discharge once every 30 or 40 charges can be beneficial but is not necessary. Embracing the 30%-60% rule ensures regular charging, thereby extending the battery's lifespan and your riding pleasure.
When initially charging a new e-bike battery, a 12-hour charge is recommended to ensure all cells receive an ample supply of electric current. Subsequently, avoid fully charging the battery to prevent accelerated degradation. Instead, maintain a charge level between 40% and 70% for extended storage periods. Additionally, when charging, disconnect the charger once the battery reaches 90%-95% capacity to prevent overcharging.
To further enhance battery longevity, consider the following vital charging tips:
Storage Conditions: Avoid storing the battery in excessively hot or cold environments. Optimal storage temperatures range from 59 °F (15 °C) to 77 °F (25 °C) in a dry location.
Temperature Considerations: Refrain from charging the battery in temperatures below 32 °F (0 °C). Before charging during winter, ensure the battery reaches room temperature.
Safety Precautions: Place the battery and charger on a dry surface, away from flammable materials, humidity, and heat sources. Avoid covering the battery or charger during the charging process.
Manufacturer's Charger: Always utilize the charger provided by the manufacturer to prevent potential damage to the battery.
Monthly Charges: Even during extended periods of non-use, charge the battery at least once a month to maintain its health and performance.
In summary, a simple rule of thumb is to charge your battery after each ride, adhering to the 30%-60% alternating pattern. This ensures your e-bike is always ready to hit the road whenever you desire.
However, with high-capacity batteries like the Delfast 3.0, boasting an impressive range of 200 miles (321 km), less frequent charging may be necessary for short commutes or leisurely rides. The Delfast 3.0's control display provides accurate battery charge information, making it effortless to follow the 30%-60% rule and optimize your battery usage.
Embrace these charging tips and unlock the full potential of your e-bike battery. Ride with confidence, knowing you have extended the lifespan of your battery and embarked on countless electrifying adventure

High-end batteries with longer ranges can provide more power with less energy consumption, enhancing rider performance on hills and allowing them to go farther before needing a recharge. Keep the range in mind when selecting an electric bike battery to get the best value and experience from your electric bike.
Speed:
Speed capability should not be the primary factor in determining the most suitable electric bike battery for you. Most electric bikes are pedal-assisted, meaning they stop providing assistance once a certain speed is reached. Electric bikes are more about facilitating easy travel from point A to point B rather than delivering thrilling speed. While speed may be an appealing feature, ensuring your electric bike battery possesses all the qualities you need will guarantee long-term value and satisfaction.
Durability:
Batteries must withstand factors such as rain, snow, and extreme temperatures so that you can ride your bike safely year-round. Durability is especially important if you plan to use the electric bike off-road or in challenging terrains where it may endure impacts. To ensure maximum efficiency and lifespan, make sure the battery offers waterproof protection and an adequate temperature range. Investing in a durable electric bike battery will ultimately save you time and money in the long run.

Consider your residence and the terrain you will be riding on when selecting an electric bike battery. If you live near hilly areas, batteries designed for flat terrains may not be suitable. You will need a more powerful battery as attempting to climb steep terrain can significantly deplete your battery. Additionally, riders in warm climates should ensure their batteries can handle high temperatures, while those in colder regions need to be aware of the adverse effects cold weather can have on battery life and power output.
Charging Points:
If you plan to ride your electric bike regularly, it is crucial to ensure you have access to sufficient charging facilities on a regular basis. For example, consider whether you will be able to charge your electric bike while at work.
In addition, charging facilities may not always be available during your journey, so it is important to consider the availability of charging facilities when determining how far you can safely ride your electric bike away from home.
Ultimately, considering where you can charge the electric bike battery is crucial to ensuring your riding safety and enjoyment.
Weight:
The battery you choose for your electric-assist bike can be one of the most important decisions you make, and your weight plays a significant role in it.
To achieve optimal performance, you must consider how much power the battery needs to propel you up steep hills and on long rides. The heavier you are, the harder the electric bike needs to work. This can significantly reduce the advertised range.
Cost:
Choosing an electric bike battery based on your budget is an important consideration as it will determine the level of performance and features you can obtain. If you allocate too little funding for the battery, you may end up with lower-quality components that cannot provide a good range or performance.
On the other hand, bankrupting yourself for an overly powerful battery that doesn't meet your needs doesn't make sense.
It's important to research electric bike batteries and their prices carefully before deciding how much budget to allocate for the battery. Budgeting wisely will ensure you get the best electric bike experience without sacrificing other important needs in your life.
Volts, Amperes, and Watts
Understanding volts, amperes, and watts and their relationships can be helpful in determining the type of battery you need. Here, we'll provide a simplified explanation.
Volts – This unit of measurement represents voltage, but it can be thought of as speed. Higher voltage means a faster power supply. Low voltage is comparable to an older car driving on a highway, while high voltage is like a brand-new supercar.
Amperes – Amperes can be likened to the size of a highway. The more lanes there are, the more vehicles can travel. Low current indicates only a few vehicles passing through, while high current is akin to a massive multi-lane highway. Higher amperage allows for a greater amount of power to pass through.
Watts – Watts are the product of volts and amperes. A low-wattage system is like a single car driving on a road, while a high-wattage system is similar to 100 supercars driving on a highway.
Generally, high watts and high amperes are closely related. For instance, it wouldn't make sense to construct an enormous power highway for a group of slow-moving cars. However, there are variations to consider.
For example, a 48V battery may have a capacity of 13Ah or 20Ah. Ampere-hours (Ah) measure how many amperes can be supplied within one hour. A higher value indicates a greater power capacity.
We hope this provides you with a basic understanding of these terms when exploring different batteries. Next, we'll discuss selecting the appropriate voltage for a battery.
Which Voltage Should You Choose?
Understanding the ratings of volts, amperes, ampere-hours, watts-hours, and watts displayed on electric bicycles can be confusing. The most common (and often the first) number you'll encounter is volts. To simplify things, let's explore what you can expect from electric bicycles with different voltage options.
24V – This represents the lower end of battery ratings. Electric bicycles with this voltage typically have advertised ranges of approximately 15 miles.
36V – This is likely the most prevalent battery voltage level as it strikes a balance between power and affordability. Typically, advertised ranges for these bicycles range from 20 to 25 miles.
48V and 52V – These voltage levels generally offer ranges of around 30 to 35 miles on a single charge. They are considered high-end electric bicycles capable of delivering impressive power.
72V – Batteries of this size are uncommon in commercially available electric bicycles, but they can be easily obtained. The range you can expect with these batteries usually exceeds 40 miles.
It's important to note that the ranges mentioned here are rough estimates. Additionally, all these batteries can have different amperage ratings, which should also be taken into consideration, particularly if you require high power output for uphill riding.
Lead-acid, Nickel, or Lithium Batteries?
Choosing the type of battery to use on an electric bicycle can be a challenging decision. Each battery type has unique characteristics, and the choice should depend on your intended usage and the riding conditions you anticipate.
For example, if you frequently embark on long-distance journeys, Nickel Metal Hydride (NiMH) batteries are a good option due to their extended operating times. On the other hand, Lithium-ion (Li-ion) batteries are lighter, making them suitable for bicycles that need to tackle steep inclines.
Lead-acid batteries are inexpensive but heavy, which is why they are seldom used in modern electric bicycles. Regardless of your choice, consider the terrain you will be riding on, the distance you plan to cover, and your budget.
Final Thoughts
If you wish to select the ideal battery, it is beneficial to have some knowledge about voltage and current. This way, you can consider all the crucial factors when choosing a battery. We hope that you now possess all the necessary information for selecting the perfect electric bicycle battery. If you have any other inquiries or require additional assistance, please don't hesitate to ask. We wish you success in finding the electric bicycle battery that is perfect for you!
Your electric bicycle battery is quite expensive. Understanding how to charge and maintain it correctly can extend its lifespan by 2 to 3 times. There are also some things to avoid that can significantly shorten the battery's lifespan. This article will tell you:
What to do when your battery is new
Basic electric bicycle battery charging guide
How to store it when you're not riding for a while
Lithium-ion batteries and safety
How to prolong battery lifespan
Charging with a "smart charger"
These guidelines and instructions assume that you purchased the battery together with the motor or electric bicycle, and their power and charging capacities are matched accordingly.
If you purchased them separately, you will need to learn more information to ensure you have the correct battery and there are no potentially dangerous combinations. Ideally, the battery should provide more capacity than the motor requires, and the charging speed should be faster than the charger's charging speed. Both have room to spare, so your battery won't be stressed, making it safer and prolonging its lifespan.
Lithium-ion batteries require minimal maintenance. The battery's longest range is achieved when it is charged between 30% and 80% capacity. Unlike other chemistries, lithium-ion batteries do not have a memory effect and can be topped up as needed.
When your battery is new:
Before use, it is recommended to fully charge the battery. For the initial charge, you should charge the battery to 100%. If time permits, leave it on the charger for about 12 hours to ensure an even distribution of battery charge. Afterward, if you have a smart charger, you can charge it to 80% or 90% to extend battery lifespan. Then, every few months or so, perform a full 12-hour charge after a deep discharge to recalibrate the battery.
Basic electric bicycle battery charging guide:
The battery can be charged on or off the bicycle.
First, plug the charger into an AC power outlet. If there is a switch, turn it on and then off. This charges the internal capacitors of the charger and prevents a surge current to the battery.
Next, plug the charger into the charging port of the battery, and if there is a switch, turn it on. Most chargers have a set of LED lights. One of them will be red during charging and turn green when the battery is fully charged. When the indicator light turns green, the charger is not charging the battery and should be disconnected.
Ensure that the battery is not near flammable materials during charging.
For Electrify Bike Co batteries with switches, turn them on before charging.
Disconnect the charger when the green light is illuminated.
Charge the battery when the remaining capacity is between 30% and 60%.
Partial charging extends battery lifespan more than full charging.
Do not charge below freezing or above 50°C (120°F).
Perform a 100% charge every 1-3 months.
Storing Your Lithium-Ion Electric Bicycle Battery
When you are not riding your electric bicycle temporarily, there are two crucial things to consider when storing the battery: the charge percentage and the temperature. If you plan to store the battery for more than a few weeks, you should set its charge level between 40% and 70%. Do not store the battery at 100% charge as it will shorten its overall lifespan. Additionally, avoid storing the battery with a charge level below 40% as the capacity may degrade over time. If it falls below its low-voltage limit (around 2.6-2.8 volts per cell), it may become permanently damaged and might not be rechargeable thereafter.
During long-term storage, it is advisable to periodically check the voltage and recharge it to above 50% as needed. This frequency can range from every 3 to 6 months.
Keep the battery at a moderate temperature. Lithium-ion batteries that are partially charged tend to have a longer lifespan when stored in a cool place. The worst combination is high voltage (100%) and high temperature. For long-term storage (several months or longer), store the lithium-ion battery at approximately 50% charge. Ensure that you do not leave the battery in a place where the temperature may rise above 120 degrees Fahrenheit for an extended period, such as a closed vehicle or a building without climate control.
If the temperature drops below 32 degrees Fahrenheit (0°C), do not charge the battery, as it may be damaged. Place the battery indoors and allow it to warm up before charging. Discharging the battery (riding the bicycle) is possible in cold weather, but it will reduce your range. However, it will not harm your battery or shorten its lifespan. Conversely, if the temperature exceeds 120 degrees Fahrenheit, do not charge the battery, as it may also be damaged.
Lithium-Ion Batteries and Safety
Lithium-ion batteries can pose a fire hazard. This risk is significantly reduced if you purchase high-quality batteries from reputable sources that use branded cells. However, the risk increases if any cells within the battery are damaged due to drops or exceeding charging/discharging limits. Do not leave charging batteries unattended, and avoid charging them near flammable materials. If the battery is visibly damaged due to drops or water exposure, it should be recycled and replaced.
Failure to charge lithium-ion batteries in accordance with the following guidelines can shorten their lifespan and pose significant safety hazards.
Lithium-ion Battery Charging Temperature:
0°C to 45°C (32°F to 113°F)
Lithium-ion Battery Discharging Temperature:
–20°C to 60°C (–4°F to 140°F)
Extreme Temperature Guidelines:
Charge at reduced current below 41°F.
Charging below freezing is not permitted.
Good charging and discharging performance at higher temperatures but with a shorter lifespan.
Extending Battery Lifespan
Lithium-ion batteries, unlike some other technologies, do not have a memory effect, so you can charge them at any time without fully discharging them. When charged to 100%, it is expected to go through about 300-400 full charge cycles before the battery capacity drops to 80% of its original capacity. In terms of range, this means that if your new battery can travel 20 miles at 80% capacity, it will only travel 16 miles after 300-400 full charge cycles.
The simplest way to extend battery lifespan is to only charge it to 80% or 90% when you won't be riding for a few days. Most recreational rides don't require a full charge anyway. Doing so can extend the battery's lifespan by 2 to 4 times. Charging to 90% will give you around 1000 charge cycles, while charging to 80% will give you around 1600 charge cycles. This is similar to how you treat your smartphone. After charging it every day for a year, you'll notice that its talk or screen time is only 80% of what it used to be.
If you know you're going on a long ride and want to ensure the battery has enough charge, feel free to charge it to 100%. Doing so before a ride won't shorten the battery's lifespan. To control charging at 80% or 90%, you would need an "advanced" or "smart" charger that has this feature. Most chargers that come with electric bicycles do not have this capability.
If you use a smart charger to extend battery lifespan by charging to 80% or 90%, you should occasionally (every 2-4 months) balance the battery. To do this, you'll need to perform a deep discharge (below 30%) and then charge the battery to 100% to give the battery management system (BMS) a chance to rebalance the battery for maximum capacity.
Subjecting the battery to high drains will shorten its lifespan. If your battery is rated for a continuous power of 40 amps, it doesn't necessarily mean you should run it at that power for extended periods. If your battery feels hot to the touch during use, it may indicate that you're drawing too much current for too long. The BMS of the battery may allow you to draw more current when needed, but you should be aware that it should not be abused.
Avoid charging the battery too quickly or too frequently. Just like electric cars with fast-charging stations, you can also fast-charge electric bicycles. Electric car manufacturers warn against relying solely on fast-charging stations as it can shorten the lifespan of the car battery. Unlike fast chargers for cars, most electric bicycle fast chargers operate within the safe charging limits of the battery and do not shorten its lifespan, unless you have found and purchased an ultra-fast charger.
For example, all the batteries used by Electrify Bike Co. can be charged at 1.5 amps without decreasing the battery lifespan. Our popular battery, the Super Shark, consists of 14 series cells and 4 parallel cells. Four times 1.5 amps equals 6 amps, so the charger can charge at a current of 6 amps without reducing the battery lifespan. Our fastest chargers are only four and five amps, which is two-thirds of the safe charging level. Each battery also has a safe fast-charging rating, but frequent use may decrease the battery lifespan. This rating is approximately 2.5 amps per cell, so a 4P battery has a rated current of 10 amps. Even the Electrify Bike 2P Mini-Max battery can handle a 5-amp charge without reducing the battery lifespan. This is one of the many advantages of using high-quality batteries in battery manufacturing.
Using "smart chargers" for charging
Smart chargers can automatically stop charging when the battery reaches 80%, 90%, or 100% capacity. This can be selected using a rotary switch at the end of the charger. Electrify Bike Company offers smart chargers in 2-amp and 4-amp sizes, suitable for 36V, 48V, 52V, and 72V batteries. We also provide advanced smart chargers with the same voltages and an additional rotary switch to select 1 to 5 amps. The advanced smart chargers also feature a display screen with switches to show voltage and current.
The recommended way to use a smart charger is to charge to 90% after each ride, so your bike is always ready to go. Then, if you're planning an extended ride and want to ensure maximum battery range, you can charge it to 100%. Charging the battery to 100% before a ride will not have a negative impact on battery lifespan.

Charge at reduced current below 41°F.
Charging below freezing is not permitted.
Good charging and discharging performance at higher temperatures but with a shorter lifespan.
Extending Battery Lifespan
Lithium-ion batteries, unlike some other technologies, do not have a memory effect, so you can charge them at any time without fully discharging them. When charged to 100%, it is expected to go through about 300-400 full charge cycles before the battery capacity drops to 80% of its original capacity. In terms of range, this means that if your new battery can travel 20 miles at 80% capacity, it will only travel 16 miles after 300-400 full charge cycles.
The simplest way to extend battery lifespan is to only charge it to 80% or 90% when you won't be riding for a few days. Most recreational rides don't require a full charge anyway. Doing so can extend the battery's lifespan by 2 to 4 times. Charging to 90% will give you around 1000 charge cycles, while charging to 80% will give you around 1600 charge cycles. This is similar to how you treat your smartphone. After charging it every day for a year, you'll notice that its talk or screen time is only 80% of what it used to be.
If you know you're going on a long ride and want to ensure the battery has enough charge, feel free to charge it to 100%. Doing so before a ride won't shorten the battery's lifespan. To control charging at 80% or 90%, you would need an "advanced" or "smart" charger that has this feature. Most chargers that come with electric bicycles do not have this capability.
If you use a smart charger to extend battery lifespan by charging to 80% or 90%, you should occasionally (every 2-4 months) balance the battery. To do this, you'll need to perform a deep discharge (below 30%) and then charge the battery to 100% to give the battery management system (BMS) a chance to rebalance the battery for maximum capacity.
Subjecting the battery to high drains will shorten its lifespan. If your battery is rated for a continuous power of 40 amps, it doesn't necessarily mean you should run it at that power for extended periods. If your battery feels hot to the touch during use, it may indicate that you're drawing too much current for too long. The BMS of the battery may allow you to draw more current when needed, but you should be aware that it should not be abused.
Avoid charging the battery too quickly or too frequently. Just like electric cars with fast-charging stations, you can also fast-charge electric bicycles. Electric car manufacturers warn against relying solely on fast-charging stations as it can shorten the lifespan of the car battery. Unlike fast chargers for cars, most electric bicycle fast chargers operate within the safe charging limits of the battery and do not shorten its lifespan, unless you have found and purchased an ultra-fast charger.
For example, all the batteries used by Electrify Bike Co. can be charged at 1.5 amps without decreasing the battery lifespan. Our popular battery, the Super Shark, consists of 14 series cells and 4 parallel cells. Four times 1.5 amps equals 6 amps, so the charger can charge at a current of 6 amps without reducing the battery lifespan. Our fastest chargers are only four and five amps, which is two-thirds of the safe charging level. Each battery also has a safe fast-charging rating, but frequent use may decrease the battery lifespan. This rating is approximately 2.5 amps per cell, so a 4P battery has a rated current of 10 amps. Even the Electrify Bike 2P Mini-Max battery can handle a 5-amp charge without reducing the battery lifespan. This is one of the many advantages of using high-quality batteries in battery manufacturing.
Using "smart chargers" for charging
Smart chargers can automatically stop charging when the battery reaches 80%, 90%, or 100% capacity. This can be selected using a rotary switch at the end of the charger. Electrify Bike Company offers smart chargers in 2-amp and 4-amp sizes, suitable for 36V, 48V, 52V, and 72V batteries. We also provide advanced smart chargers with the same voltages and an additional rotary switch to select 1 to 5 amps. The advanced smart chargers also feature a display screen with switches to show voltage and current.
The recommended way to use a smart charger is to charge to 90% after each ride, so your bike is always ready to go. Then, if you're planning an extended ride and want to ensure maximum battery range, you can charge it to 100%. Charging the battery to 100% before a ride will not have a negative impact on battery lifespan.
The first step in converting a regular bicycle into an electric bicycle is to install the battery. The installation process is relatively simple, but it is important to thoroughly understand the process before deciding where to place the battery.
How to Install an Electric Bicycle Battery
Electric bicycle batteries can be installed on the bicycle in various ways. Most electric bicycles come with pre-installed batteries and mounting features. However, if you want to change the installation orientation for convenience or install the battery on a new bicycle, you will need to follow some simple instructions.
What You Need:
Battery case
Heat sink
Rivet nuts
Bolts, screws, and nuts
Wires and connectors
Wrenches (regular, Allen, rivet)
Screwdriver
Installing the Battery on a Brand New Bicycle:
You can purchase a complete kit with a display, motor, throttle, and speed sensor online to convert your regular bicycle into an electric bicycle.
Step 1: Remove Old Components
Remove the chain, bottom bracket, pedals, mechanical lines, and brakes. Converting your regular bicycle into an electric bicycle means removing almost everything from the old bicycle.
Step 2: Install the Electric Bicycle System
Mount the motor on the bottom bracket and lubricate it. Install the display, brakes, and throttle on the frame.
Step 3: Initialize Connections
Connect the display, throttle, brakes, and motor to the controller. Additionally, connect the speed sensor to the rear wheel.
Step 4: Choose Mounting Options
Mount your front rack or rear rack or triangle pack onto the bicycle.
Or
Drill a few holes, insert rivet nuts, and tighten them. You can now install the sliding mounting options onto the bicycle frame.
Step 5: Install the Battery
Mount the battery onto the mounting option, connect the battery, and it's done.
Step 6: Connect the Battery to the Bicycle
The overall wiring of the electric bicycle may seem complex, but connecting the battery is the simplest part so far.
You simply need to place the battery in the installation position and plug the connector into the controller.
While the connection between the bicycle and the battery may be straightforward, the wiring connection to the controller can be quite complex. For more information, you can refer to the instructions.
Different Mounting Options for Changing the Battery
Various DIY Battery Mounting Options
Rear and Front Rack Mounting:
The most common mounting option for a DIY battery on an electric bicycle is the rear rack option. Almost all bicycles are rear-wheel-drive (rear tire moves first), which is helpful for bearing heavy loads at the back.
Front frame battery mounting brackets may not be as popular as rear frame options, but they are undoubtedly a convenient choice for installing a DIY battery.
Pack (Triangle and Top Tube) Mount:
Using a triangle pack for mounting a DIY battery will be the simplest and sensible decision. The pack will be placed in the middle, which is perfect for achieving optimal weight distribution on the bicycle. Additionally, you don't have to waste time searching for wrenches or screwdrivers every time you need to remove the battery—taking out the pack is simple and hassle-free.
Top tube packs for mounting DIY batteries may not be as common, but they are also easy to install and detach on the bicycle frame.
Dolphin Case and Water Bottle Holder:
Both dolphin cases and DIY battery water bottle mounts utilize the bicycle frame's water bottle cage.
Larger batteries may not fit in these, so you may need to replace the water bottle cage with a larger one.
The advantages of these two mounting options are ideal weight distribution and ease of detachment.
