Choose a bike with wheels that are 26", 20", or 16" as these are the most common off-the-shelf wheel sizes. The smaller the wheels are usually found on folding bikes and will accelerate more quickly, be bumpier, and be less efficient at cruising speed. Mountain bikes are most commonly converted to electric bikes, though you could use a different type as long as it has a strong frame and standard bottom bracket. Don’t use a bike with a carbon fiber frame or forks, as these aren’t strong enough to support the extra weight or handle the extra torque.

Ensure the kit comes with a wheel that is the same size as the existing wheels on your bike! It’s much easier to replace the front wheel than the back, due to the position of the gears, so opt for a kit in which the hub motor is on the front wheel. In most cases, the battery doesn’t come with the conversion kit. For ease of installation, though, it’s best to purchase the battery and the conversion kit from the same manufacturer.
The capacity of the battery defines how long it’ll last. If you’ll be taking short trips, a 10Ah will suit you well, while a 20Ah battery will provide you with extra capacity for slightly longer journeys. [5] X Research source
To remove the front wheel, turn the bike over so it’s sitting on the seat and handlebars, then flip the quick-release lever over to the “open” position. Then, simply lift the front wheel off of the bike. [7] X Research source To remove the back wheel, crouch behind the bike. Hold the frame with your non-dominant hand and use your dominant hand to pull the derailer backward. Then lift the bike frame up and off of the rear wheel with your non-dominant hand and unhook the chain with your dominant hand. [8] X Research source
Adjust the brakes as needed, either by aligning the calipers (for mechanical brakes) or pumping the brake lever (for hydraulic brakes).
If you have any other accessories, attach them as well. Secure the speed sensor to the back wheel and connect any displays and gauges to the handlebars with the included hardware. [12] X Research source
Alternatively, you could place the battery in a box or basket on the front or back of the bike, particularly if it is too large to fit well on the frame (such as if it’s more than 60 volts).
