Silver 2 1/2 / ELECTRIC BICYCLE

Silver 2 1/2
Silver 2 1/2

Nowadays, to design a vehicle with high efficiency and environment protection is a very important issue all over the world. We use the 2.5 wheels concept to have the advantage of both bicycle and tricycle and focus on the future daily needs of the GREY-HAIRD as a replacement of the short-distance transportation,. The extendable distance between two front wheels can increase the balanced state of the bicycle and provide the convenience for GREY-HAIRD to place their shopping basket. The vehicle is driven by two electric hub-type motors in the front wheels and is controlled by an electronic differential mechanism.
