There are three types of elettric bicycles drive modes:
– mid-wheel drive
– rear-wheel drive
– front-wheel drive
The mid-engine with the drive via the bottom bracket bearing gives the electric bicycle a very balanced distribution of mass and thus stable vehicle dynamics. The probability of malfunction of connecting parts is lower, because controls, motor, and accumulator have only few cables and connecting parts. A disadvantage of many of these models are the higher repairing costs and time in case of a defect. Back-pedal brakes cannot be used with a mid-engine either.
The vehicle dynamics are also quite stable when using a drive in the front axle. In loose, sandy terrain, however, the traction is somewhat lower, which is particularly disadvantageous on hills. In this case a rear-wheel drive is preferable. The disadvantage of a rear-wheel drive is a rather unfavourable load distribution, since both drive and accumulator are situated in the rear – this gets even worse when you add luggage in the back. An advantage of a hub drive is that the repair or removal of the drive is less time consuming. In addition you can replace the drive wheel by a conventional wheel in case of a defect and use your electric bicycle like a conventional bike.
