What Range Can I Expect on a Full Charge?
It depends! As a general rule, you'll be able to comfortably ride anywhere between 35 & 70 miles, on a full charge, depending on the route, conditions, battery capacity, model of motor & power modes you use.
Most e-bike component manufacturers will offer a chart to describe the sort of performance you can expect, allowing you to plug in different values for the motor, battery & type of bike.
The display on most e-bikes will also show an estimated remaining range, which is good for making sure you're going to make it home without running out of juice!
