When we choosing to buy commuting tools, we will consider buying an electric bicycle. It does not pollute the environment and can exercise, but the price of an electric bike is very expensive, so many people will choose to buy a bike kit, it’s the price is much cheaper, So how do we choose an electric bike conversion kit? Is the cheap e-bike kit worth buying?

Advantages
1. The after-sales service will be very good
2. Electrical components and mechanical components are very well matched.
3. The electric bike looks nice. A lot of modern e-bikes have integrated batteries and internal cable routing.

Disadvantages
1. The price is very expensive, especially after the end of the warranty, the cost of replacing accessories is very high
2. Not easy to upgrade – if you find yourself needing a longer range battery, sometimes the option is not available.

If you own a regular bike and have enough experience and interest to retrofit it, We suggest you buy a kit that not only makes life more interesting but also saves a lot of money. So how do we choose a cheap and useful e-bike kit?

Motor selection: Hub Motor vs Mid-drive

Hub Motor Advantages
1. One of the biggest advantages of hub motors is that they require little or no maintenance.
2. That enclosed system also means there is a lot less to fail.
3. Gearless hub motors, on the other hand, have zero moving parts aside from their bearings, so there is basically nothing to wear out. As long as they don’t rust out or wear down their bearings, they can pretty much last forever.
4. Hub motors are much cheaper than mid-drives.

Hub Motor Disadvantages
1. Hub motors are usually heavier than mid-drives
2. Hub motors can be more limiting when it comes to wheel components such as rims, tires, and cassettes.
3. It just isn’t as efficient to use a single speed motor when functioning at the lower RPM range under load.
4. Tire changing is also more difficult with hub motors

Mid-drive Advantages
1. The single largest advantage that mid-motors have over hub motors is their gear ratio. They allow the
2. A mid-drive motor is also usually smaller and lighter than a hub motor of similar power.
3. Changing a tire on a mid-drive motor e-bike is much easier since you don’t have a heavy hub motor to deal with.
4. Mid-drives uses the bike’s transmission as the motor’s gears, so the electric motor can run in the optimum RPM range.
5. The main advantage of mid-drive motors over hubs is their hill climbing ability, so it is the best option for building a full-on electric mountain bike.

Mid-drive Disadvantages
1. Because of the increased number of moving parts in a mid-drive motor, there are more points of failure.
2. Mid-drives motors are much expensive than a hub motor.

Battery selection

Battery selection
Most of the kits listed below using either a 36v or 48v battery, but some of the more powerful kits use 60v or 72v batteries. You will need to make sure your battery voltage matches that of the motor controller.
Lead-acid is a tried-and-true technology that costs less, but requires regular maintenance and doesn’t last as long.
Lithium is a premium battery technology with a longer lifespan and higher efficiency, but you’ll pay more money for the boost in performance.
Sealed lead acid batteries can be used if you don’t mind the extra weight and size.
Personally, I would stick with lithium batteries, as they are coming down in price now, they are much lighter and last longer than lead-acid batteries.

Electric bike controller


An electric bike controller is an electronic circuit that not only controls the speed of an electric motor but also serves as a dynamic brake. This controller unit uses power from the battery pack and drives it to the hub motor. Different types of controllers are used for brushed and brushless motors.
