Electric bike crank motor also called mid drive motors, crank drive motors directly power the crank drive, and usually work in concert with your gears. Crank drive motors tend to be more about smooth and efficient performance than simple brute force.
Advantages of Electric Bike Crank Motor
1. The motor has a fanned casing which allows for heat to be more effectively released than in a hub motor.
2. Electric bike crank motor will be in or near the bottom bracket, so the extra weight is low on the bike – contributing to good balance and a classic bike feel.
3. The key advantage is that by working synergistically with the bike’s gears, the bike can perform better on hills than an equivalent sized hub motor.
4. E-Bike crank motors can do well with quite low power levels because they work so efficiently.
