You will definitely stand out on the road on this radical canary yellow bike called a “Cycle Sol” which works like any regular pedaled cycle, but it has a canopy lined with solar cells overhead that charges by the sun, or by plugging into a regular power outlet.
The solar cells charge up a battery which powers a small electric motor hidden in the back wheel.
While you won’t be winning any bike rallies on its own power which has a top speed of 15 mph (24 km/h), it will save on ‘leg power’ to make pedaling easier and lower the resistance in peddling up hills.
Its handle bars are positioned on either side of the seat rather than the front so you can lean back for a comfortable, leisurely ride.
