What to do Before You Purchase a Motorized Bicycle Kit

  1.  Determine the Right Type of Kit for Your Bike

When you are picking out a bicycle engine kit, it is vital that you choose the right kind of engine kit that is suited to your bike. To do this, you would need to ask yourself two questions.

The first is, what is your bike’s wheel cycle? Some kits can fit only 26 inches or a 28 inches-wheeled bike. Others can fit a 24 inches-wheeled bicycle. You should always check to know if your bike meets the wheel cycle requirement before you buy.

This way, you will not buy a kit that you will no be able to use or a kit that will force you to get a new bike.

The second question is, what is your bike’s seat tube height? In a normal V-frame bike, most kits require that the seat tube height falls between 9 and 11 inches. This way, there is enough clearance that will leave enough space so you can install the bike engine.

If your bike does not meet the requirement, then you should better purchase a kit that can be mounted somewhere else, like the rear.

Once you are able to answer these two questions, then you will be able to get a kit that is compatible with your bike.
