Jueshuai is a well established maker of electric bike motors and offers a front/rear hub based motor, if you're not a fan of the bulky profile a mid motor conversion system creates. You can buy this kit . Advantage of Hub Motor：1. Power saving. In-wheel electric vehicles are more power-efficient and efficient. Since the in-wheel motor is directly driven by the front/rear wheels, there is no energy loss during the transmission process, saving more power!2. Low wear.When the hub motor is running, the current is relatively uniform, and it relies on electromagnetic induction to operate, with low noise and low wear.3. Simple maintenance.The motor is not easy to burn out, the installation and disassembly are more convenient, and the maintenance is simple. 
How to Measure a Bicycle Wheel SizeMethod 1:If your tire is mounted, you can find the wheel size on the bicycle's tire.Method 2: Measure the distance in inches from the ground beneath the tire to the center point of the wheel. This measurement is the wheel's radius, or half of its diameter. Multiply the length by two in order to calculate the tire's diameter. With the exception of BMX models, most adult bicycle wheels are between 26 and 29 inches in diameter
