The biggest factor contributing to your range is whether you pedal or use a throttle without pedalling and what level of assistance you use. Thunder E-bike is a strong proponent of the synergy resulting from combining human pedal power with electric power, so we’ll tell you the expected range when you do both. With relaxed pedalling, expect 40-75 km on a single charge. In some cases, you’ll go even farther. We have bikes that are getting 120km or 300km on a single charge. The battery capacity, the hills, the wind, and your size impact the range. Many electric bikes pedal easily as regular bikes. So you can extend the range even further by using little or no power on level surfaces and downhill.
