<p>The present invention describes a bicycle which may either be driven manually by the user or by power stored in rechargeable batteries wherein the batteries are charged by a solar panel or by a D.C. charger (operating on A.C. mains). The bicycle is a light weight, geared bicycle, supplied with a brushless D.C. hub motor (fixed on axel of rear wheel) receiving energy stored in a battery charged by solar energy with help of solar panels fixed on the bicycle or by electric energy by D.C charger (operating on A.C. mains). The shifting of charging mode is done automatically due to auto switch. The bicycle is further equipped with a low battery cut off system and a high battery cut off system and a battery level indicator to prevent damage to the battery and a speed control device to automatically cut off the power supply to motor if the bicycle exceeds its speed limit and automatically restart power supply to motor when the bicycle speed goes down the speed limit.</p> |
