When compared to a hub motor, a MID drive is an elegant solution. This is because MID drives allow you to use the bike's transmission as the motor's gears, so the electric motor can run in its optimum RPM range. This translates to a happier more efficient motor and a lighter better balanced e-bike. Why a lighter bike? When going through the gears, you dont need as heavy a motor to propel you up hills without smoking, and you dont need as much battery because a MID drive is considerably more efficient than a hub motor especially when climbing.

Package & Delivery:
Crank MID drives are the holy grail power-providers for electric bikes. If you want to know how you can spend a lot of money on an electric bike and get the ultimate in efficiency and performance this is a good start. MID drives are not the easiest or the cheapest electric bikes to build, but can be the cream of the crop once you are out riding, especially off road, especially climbing hills or even mountains. When compared to a hub motor, a MID drive is an elegant solution. This is because MID drives allow you to use the bike's transmission as the motor's gears, so the electric motor can run in its optimum RPM range.
