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.
