Electric Bike Conversion Kit Guide – What You Need to Know

Thinking of converting your bicycle into electric, but don’t know where to start? In this e-bike conversion kit guide, I will look into the different ways you can add an electric-assisted bike.

If you are willing to take risks, it can be a very rewarding experience to convert your bicycle into an electric assisted bicycle. Not only that, you can also save a lot of money compared to buying factory-produced electric bicycles

So, what must you do? So, what must you do? It’s very simple, all you have to do is replace the power wheels with the front or rear wheels of your existing bicycle.

1. Choose the right e-bike battery
Most kits are 36v or 48v, 48v kits usually require 52v batteries, but in some cases, this may compromise reliability. There are some motor controllers that can use 36v or 48v batteries

The Ah (Ampere Hour) specification provides a measurement of battery capacity. In other words, it is an indication of how much energy the battery can store. For example, a 36v 13ah battery (36v x 13ah) has a total energy of 468 watt-hours (watt-hours)-using a constant 20 watt-hours per mile, the cruising range is about 23 miles. In real-world riding, this number may be larger or smaller, depending on the power level used, rider weight, terrain type (flat or hilly) and wind direction.

2. Type of conversion kit
Rear wheel electric bike conversion kit
Gear Hub Motor
Small geared hub motors are much more efficient than direct drive motors. The motor housing is connected to the stator through a planetary gear reduction system. Every time the housing rotates, the motor inside turns many times faster. This allows the motor to work at higher (and more efficient) speeds, while still allowing the wheels to spin at a lower travel speed.

Another benefit of using a geared hub motor is that if the motor is turned off or the battery runs out, there is almost no resistance to pedaling-you can pedal like a normal bicycle.

LCD Display: to show battery power, time, speed, mileage and gears
Pedal Assistance System (PAS): let you enjoy cycling while driving electric bike
Dual Mode Controller: Motor works under Hall effect and non-Hall effect, extend life for electric bike

Best Electric Bike Conversion Kits:
1.Battery Choice: For the Hailong battery box, we currently provide 5 battery pack models, all are using li-ion 18650 cells. The electric bike conversion kit is available without a battery and can be powered by any 36V / 48V battery pack. Kits purchased without a battery pack come with a battery wire harness for connecting to the E-Bike Kit controller.

Choice 1:

36V 10AH Hailong battery
40 pcs 2500mAh battery cells+Hailong case+BMS
Range: 20-30Miles

Choice 2:

36V 13AH Hailong battery
50 pcs 2600mAh battery cells+Hailong case+BMS
Range: 50-60 Miles

Choice 3:

48V 10AH Hailong battery
52 pcs 2500mAh battery cells+Hailong case+BMS
Range: 35-45 Miles

Choice 4:

48V 11.6AH Hailong battery
52 pcs 2900mAh battery cells+Hailong case+BMS
Range: 40-50 Miles

Choice 5:

48V 13.4AH Hailong battery
52 pcs 3350mAh battery cells+Hailong case+BMS
Range: 50-60 Miles

If you have a full suspension mountain bike, it is practically impossible to install a battery on the frame (depending on the bike). Ladies frame bicycles and scooters are usually more suitable for rear rack batteries.

3. Bafang 8FUN is our first choice for the best electric bike modification kit. Although this is a rather expensive option, it is one of the best mid-drive conversion kits to date.

The mid-drive system provides you with two working modes; you can switch between pedal assist, or you can choose throttle-only mode, which will provide you with explosive speed.

First of all, the in-wheel motor is completely independent of the transmission chain. Although we do not claim that in-wheel motors are better than intermediate drives, both have pros and cons. When the chain breaks, there is a problem with the flywheel, or the derailleur is damaged, the hub motor can still continue to move the bicycle until the rider reaches the destination.

It is friendly to the chain because the hub motor reduces the mechanical wear of the gears. It reduces the pressure on the pedal and the chain, unlike the middle drive motor.

The mid-drive motor is the drive system of choice for more expensive electric bicycles. So far, these types of motors are the most efficient and also produce higher torque than hub motors.

The in-wheel motor with the torque arm installed correctly will not have peak power problems. It can be accelerated easily without relying on the chain.

The hub motor is easy to install. Especially installing the front hub motor may be the easiest type of ebike conversion. Just remove the existing wheel and replace it with a hub motor wheel.

The hub motor will not have any downshift or upshift problems. You can hang the bike in any gear, and you can use the motor to accelerate without shifting gears.

Most mid-drive kits are only compatible with standard threaded bottom bracket housings that are 68 mm-73 mm wide and approximately 33.5 mm in diameter.

If installed correctly, the mid-drive system will make your bike look and feel like a more expensive electric bike.

The only disadvantage of the mid-drive motor is the increased pedal resistance when the motor is turned off and regular maintenance (such as tightening the motor). You will also be restricted to one chain link in front.

In the long run, small in-wheel motors are usually a lot less troublesome than mid-drive. Another thing to consider is pedaling resistance. When the motor is turned off, both the intermediate drive and the direct drive hub motor will produce a lot of resistance.

The mid-drive is definitely much better in terms of climbing. A 250-watt Bafang BBS01B will produce nearly 100% torque than an equivalent gear hub motor.
