Frequently asked questions
On 3,000 miles a year replacing car journeys, typically under two years. If you also replace a season ticket or a second car, the payback can be under a year.
Modern e-bike batteries last roughly 500β1,000 charge cycles, about three to five years of regular use. Spreading the replacement cost across those years keeps the comparison honest.
Charging a 500 Wh battery costs a few cents and adds perhaps $10β$20 a year. It is small enough to leave out, but you can add it to the maintenance figure.
