Heybike Mars 2.0
A folding fat-tire e-bike that punches above its price: a 750 W motor, a 600 Wh battery and 20x4 tires that fold down to fit a car trunk. The app lets you dial the speed and class, which is either handy or a gimmick depending on where you ride.
What you get
- 750 W motor and 600 Wh battery for a claimed 45-mile range
- Folds for storage and car transport — rare at this price
- App-adjustable speed/class, defaulting to a legal Class 2
Trade-offs
- Heavy at ~75 lb — 'folding' does not mean 'light'
- A separate 1000 W variant muddies which model you're buying
- Cadence-style assist is less refined than a torque sensor
