It depends on quite a number of factors: How much you use your motor and how much effort you are able/willing to put in. Rider weight is a big factor - the lighter the rider, the longer the battery will last. How hilly your route is - the more hills, the faster your will use your battery. The riding surface - sticky muddy conditions demand more of your motor, while the lower resistance of riding on hard, dry surfaces or tarmac will give you more range. If you use lots of power and are riding in tough conditions, the battery might only last a few hours, but if you use your power more sparingly and choose a less demanding route, you can ride for 5-6 hours. In any case, we'll be happy to discuss your ride in advance and give you a good idea what to expect in terms of range.
