While solar powered cars, catamarans etc. are already being manufactured, solar-powered electric-scooters are yet to enter the market.
This is probably due to the difficulty in installing solar-panels on top of electric bicycles, scooters or motorcycles.
The panel can be installed by fitting two steel-tubes vertically on the front chasis or the handle bar which arch backwards at 90 degrees above the rider's head.
The Solar-Panel can be fitted on the tubes above the rider.
This will increase the range of the Electric-Bikes as well as protect the rider from the Sun, especially during summer. The Solar-Panel will also protect the rider from rain.
