Price and specs last reviewed Jul 15, 2026
The DUOTTS F20 pairs a 52V 27Ah battery, one of the largest packs in the catalog, with a 1000W peak motor and 70 Nm of torque in a full-suspension fat tire frame built for gravel, sand and steep pitches. Manufacturer range is rated at 87 miles; expect closer to 56 miles in real-world mixed-terrain riding, still among the longer ranges in the fat-tire class. At 83.8 lbs and $1,099, it undercuts most 1000W full-suspension fat-tire e-bikes on price without giving up dual suspension or Kenda's grippy 20x4.0 tires.

- ✓ Full suspension front and rear
- ✓ 1000W peak motor with 70Nm torque
