How fast can it travel using only power?
When you ride your bike and use power only you can travel up to 18 Km/h (11 Mile/h) in flat roads and using the highest gear, of course terrain conditions, the uphill factor and the headwind can decrease your speed. If in addition to the power from the bike you also assist with pedaling you will go up in speed to about 28 Km/h (17 Mile/h).
