Conversion Kit Comparison: Front-Wheel, Rear-Wheel, and Mid-Drive Motor

Adding an electric motor to your traditional bike will give it more power and speed.

Bicycles have been around for decades, and the new electrified models add more range, so they’re suitable for lots of riders.

There are several e-bike designs and systems available on the market. These systems refer to the location of the motor and determine what it can do.

Understanding the features of each type will allow you to pick the most suitable one.


This is the most straightforward e-bike conversion kit design, but it’s also the one with the most limitations.

Throttle operated e-bikes move forward without any additional pedaling or extra effort from the rider, and this is where you’re likely to find the front-wheel system.

However, due to that particular feature, front-wheel systems and throttle-type bikes are not legal in European Union countries, where the e-bike should provide power only when the pedals are moving. As a result, you might find that front-wheel systems are more available in other parts of the world like the US.

Nevertheless, there are several front-wheel models that would allow the bike to move forward, only when the rider is using the pedals.

Theses kits are quite affordable, so they’re more suitable for occasional riders. Moreover, they’re easy to install so that anyone can add one to their existing standard bike.

However, these e-bike systems have several drawbacks, especially with traction, because most of the bike’s weight is not balanced.

Cornering and accelerating can be a little tricky when you have a front-wheel system. This is why people who buy these kits will not be particularly interested in going at full speed.


Pedelec or pedal-assist e-bikes are likely to have a rear-wheel system. These bikes will move forward when the rider pedals, but the motor will increase the power and give the bike more energy to go faster. The engine pushes the rear wheel to run faster, decreasing the effort of the cyclist’s muscles.

As a result, most riders favored rear-wheel systems as they decrease the effort and strain, without affecting the overall experience of riding a bike. Even in higher gears, the rider can go pretty fast without exerting much effort.

Pedal-assist e-bikes have settings to control the speed, but in the US and EU, the government’s maximum speed is set, so riders can still ride in traditional bike lanes without needing an extra license.

Rear-wheel motors can also be found on throttle-type e-bikes, and you might even be able to switch between both systems on the same e-bike.

Nevertheless, more experienced riders might feel that the bike is less balanced, as the rear-wheel system will add more weight to the rear wheel than the front one.


This conversion system will keep your e-bike balanced on all roads because it’s attached to the middle of the frame, without adding unbalanced weight to the front or back.

The system is then integrated with the crank and bottom bracket, giving the rider more control on steep and more challenging roads.

Mid-drive systems are not installed on throttle-type e-bikes, so they will always be found on a pedal-assist model. Since the motor is located in the center, it will give the e-bike more torque than an engine located on the front or rear wheel. Moreover, the weight is distributed evenly, which provides the rider with more control over the direction and speed of the e-bike, especially on more challenging trails.

The motor in this system will be attached to the crank and not the wheels. As a result, it will allow the rider to take better advantage of the range of gears on the e-bike.

The mid-drive motor will have a torque sensor that calculates the power provided by pedaling and transforms it into power supplied by the motor to make the ride smoother, less tiring, and more fluid, regardless of the condition of the trail.
