We built the quadbike or 4 wheel bicycle with electric power. Technically, this vehicle uses a bicycle component, but the pedal been eliminated. We built this quadbike starting in February 2014, by made the framework of the body in 3abike Bandung, and followed by finishing at January 2015 in Yogyakarta by mas Wiwien Vegas who also is the owner of Mobilijo, the shop manufacturing of electric cars in Yogyakarta.
His quadbike or electric quadricycle powered by a 48V 20Ah battery and the engine is Brushless DC 48V 750 Watt and has a maximum cruising speed of 35km/h with a distance of 35km, which is sufficient for going to the office. Currently, this quadbike standby at my office headquarters as an icon for the concept of green energy.
The next following development that will be done on this 4-wheel electric bike is the addition of a capacitor to lighten the load current from the battery and add solar cell panels as roof to recharge the vehicle.
