The most common type of electric bike is the pedal assist or pedelec. The rider pedals the bike normally while a motor provides assistance, increasing the power transmitted to the rear wheel. The pedaling takes far less effort than it normally would, even in high gears, which allows for higher speeds and effortless climbing over steep hills. Settings can control the amount of assistance the rider desires but to be considered a Class 1 e-bike in most of Europe, the system cannot provide assistance over 25 kilometers per hour (kph) or approximately 15 miles per hour. In the US this class is limited to approximately 32 kph or 20 mph. A class 1 designation allows these bike to be used on most roads and paths where normal bikes are allowed and do not require any additional licensing.
