We have reviewed the best electric conversion kits for bicycles. If you are in a hurry, the table below gives a quick snapshot. Or you can scroll down for detailed product reviews.

E-bikes have recently started gaining a lot of popularity since they are a low-cost, motorized, non-polluting vehicular option for people who want to travel green but don’t want to break a sweat while doing it.

Another reason for the recent increase in usage is that biking has gained a reputation as a calorie burner, and a lot many people have taken to biking as a hobby. Having the electric option available when you are biking is always a good thing, in case you get tired and want to head back without having to pedal all the way.

Thirdly, with the kind of traffic in large metro cities today, biking to the office has become more than just a fad, it is indeed a legitimate way to commute, and no one wants to enter the office huffing and puffing after having pedaled all the way from home.

Knowing all of this, we are aware that many of our readers are asking the questions: what is the best way to go about getting an electric bike? Well, one simple way is to of course go out and buy a ready-made e-bike. There are several options available, each more powerful than the other, and all of them are expensive as hell!

The other way is to take a standard bike that you like, strap on an e-bike kit that fits your bill for the dream e-bike that you always wanted, and you’re ready to hit the streets!

While it may not give you the most optimal and powerful e-bike out there, this is a practical, relatively inexpensive, and working method to go about getting your dream e-bike.

What Are the Different Types of E-Bike Kits?

E-bike wheels

This entails replacing either the front or the back wheel of a regular cycle with an e-bike wheel, a battery case, and a motor and gearing box.

Unless the battery pack can be mounted on the bike’s frame, it makes sense to have the front wheel be used for the e-bike. This is because the battery tends to make the cycle imbalanced and can cause great damage. If you are planning to use the bike mainly on the road, then this is the method for you.

However, if you are planning to use the bike for dirt-biking, or other off-the-road activities, then you might be better off using a back e-wheel.

Mid-drive conversion

Mid-drive conversion is also a popular way of converting your normal bike into an e-bike. A mid-drive uses a battery + motor assembly mounted on to the frame, with the motor attached to the bottom of the assembly most of the time.

Mid-drive conversion is the standard form of assembly used in professional e-bikes, so we’re in good company if we are using this method. The drawback, however, is that the motor remained exposed (especially when driving off-road). This can lead to damage and the assembly retiring a bit earlier than it was intended

Friction drive

A friction drive involves a motor and a roller installed above the rear wheel and uses friction to move the wheel along. This is not a very efficient method to make an e-bike, which is why this method is rarely used.

Concealed method

The concealed method of creating an e-bike uses a motor and battery that is run through the tubing of the frame of the bike.

Other components

Apart from the motor and the battery, the following other components are also of interest if you are looking to make an e-bike using an e-bike kit.

Controller: The controller is a digital display that shows you important information about the bike – the current speed, distance covered, battery power left etc.

Throttle: Some e-bike kits come with a throttle, which can then be pressed to move the bike without having to use your legs at all. If instead, your kit has a pedal-assist instead of a throttle, then you will need to engage your pedals in order for the motor to power the bike

Brakes: Some e-bike units have special brake levers that will cut off acceleration the moment you apply your brakes.
