How far can an e-bike really go on one charge?

Real-world range depends on battery size, assist level, terrain, rider weight, and wind. A typical 500Wh battery delivers 30-60 miles on mixed terrain with moderate pedal assist. Manufacturers often quote optimistic ranges tested on flat ground at low assist. Expect roughly 15-20 Wh per mile for a realistic estimate — divide your battery's Wh capacity by that to get your actual range.

What is the difference between a mid-drive and hub motor e-bike?

Mid-drive motors sit at the cranks and leverage your gears, providing better hill climbing and more natural ride feel. Hub motors are in the wheel (usually rear) — simpler, cheaper, and lower maintenance. Mid-drive excels for hilly terrain and off-road; hub motors work well for flat commutes. Mid-drives cost $500-1500 more on average.

What are the different e-bike classes?

Class 1: pedal-assist only, max 20 mph — allowed on most bike paths. Class 2: pedal-assist plus throttle, max 20 mph — allowed on most roads and some bike paths. Class 3: pedal-assist only, max 28 mph — often restricted from bike paths, may require helmet. Class determines where you can legally ride, so check your local regulations before buying.

How much does e-bike maintenance cost annually?

Budget $200-400 per year for regular maintenance: brake pads ($20-40 every 2,000 miles), chain replacement ($15-30 every 3,000 miles), tire replacement ($30-60 each as needed), and an annual tune-up ($100-150). Battery replacement is the big expense — $400-800 every 3-5 years. Keep the drivetrain clean and the battery properly stored to maximize component life.
