E+ Electric Bike

E+ Electric Bike

The E+ Electric Bike is available in six styles of bike that are all a variation on a hard-tail mountain bike. The E+ comes standard with a 750 watt BLDC rear hub motor but there is a high torque 85 Nm 1kw hub motor as an upgrade option. Both hub motors have built in inverters so there’s one less box to find mounting space on the bike frame for. The front hub mounted battery pack is something we’ve never seen before on an e-bike. The internal layout is very similar to a hub motor with the stationary inner structure (called the stator) attached to the axle while the outer housing is attached to the rim via spokes and rotates as part of the wheel. Thirty NiMH battery cells are arranged in six groups of five cells arranged in a polygon layout parallel to the axle and mounted on the stator. The battery pack puts out 36 volts at 9 amp hour giving a battery capacity of 324 watt hour. (0.324kw/hr). No electric only range is quoted as this is very dependent on terrain, how much you pedal and the amount of regeneration possible but each battery charge should give between 20 and 40 miles (32 – 64 km). A full charge from a 110v wall socket will take four to six hours and cost about $0.03.
