Competitor ranges estimated proportionally from battery capacity. Actual ranges may vary.
| Mode | Range (mi) |
|---|---|
| PAS 1 (Eco) | 47–68mi |
| PAS 2 (Tour) | 31–47mi |
| PAS 3 (Standard) | 22–31mi |
| PAS 4 (Sport) | 16–22mi |
| PAS 5 (Turbo) | 11–16mi |
| Throttle Only | 19–25mi |
Range varies by rider weight, terrain, temperature, tire pressure, and wind. Upper range reflects lighter rider (~130 lbs) on gentle terrain. Lower range reflects heavier rider (~200 lbs) on moderate hills.
Built like a bike. Rides like a bike. Lasts like a bike.
Up to 68 mi on eco. That's more range than Lectric and Aventon Sinch in a frame that folds in 30 seconds.
Fits in your trunk, RV, boat, or apartment closet. Unfold and ride — no assembly, no tools.
Most folding eBikes cap at 20 mph. The Twist runs 28 mph with pedal assist. A real bike, not a toy.
