A 750W (2200W peak) fat-tire electric bike built for adults, with a default 20mph street mode that unlocks to 30-32mph off-road. The 48V 15.6Ah battery is rated for up to 75 miles in pedal-assist or 40 miles on throttle alone, paired with 20x4.0 fat tires and dual disc brakes.

  • 750W motor with 2200W peak output
  • 48V 15.6Ah battery rated to 75 miles PAS range

Who it's for

Riders who want one electric bike that handles both paved commuting and rougher trail riding, and who don't mind some assembly out of the box. Not the pick for someone who wants to unbox and ride in five minutes, since a front tire and handlebar installation is part of setup.

Pros and cons

Cons
  • Requires front tire and handlebar assembly
  • One reviewer hit a persistent E10 error code
  • Seat comfort fades on longer rides per one report

Performance notes

The 750W motor with a 2200W peak is geared toward torque for climbs, defaulting to a 20mph street-legal setting that can be unlocked for higher off-road speeds.
