Radster™ Trail Electric Off-Road Bike

Smooth off the Beaten Path

Off-road fun meets eye-catching style.

Rugged good looks are just the beginning.

The Radster Trail is an electric off-road bike with the power to do anything, and the range to go anywhere. The 100 Nm motor makes quick work of hills, the 28 mph top speed promises fast-paced fun, and with two frame sizes for a personalized fit, it’s so comfortable that you’ll barely feel like you’re roughing it.

  • Up to 65 miles per charge
  • 370 lb. (290 lb. max rider
  • 750W / 100 Nm
  • Versatile and well-rounded, the Radster Trail is a compelling combination of comfort and capability that will appeal to a wide range of riders
  • One of Rad’s best motor experiences to date. The new 750W, 100 Nm of torque climbs hills easily, but it has very manageable power for any rider.
  • We love the enhanced fire safety with Rad Power’s new Safe Shield Battery, which features individual fire barriers for each cell, effectively preventing battery fire “runoff” and providing peace of mind.
  • Impressive range of over 75 miles on a single charge, achieved through the combinatin of a high-capacity 720Wh battery and an efficient torque sensor.
  • Better handling than most fat bikes. The 3”-wide tires are still very stable, yet feel livelier in turns than most 4”-tires.
  • Well-equipped for commuting, with integrated turn signals, front and rear lighting, fenders, and a rear rack, making it a practical choice for daily rides.
  • We like the increased e-bike security with the included proximity key fob (or backup password), providing an added layer of protection against unwanted use.
  • Braking felt solid thanks to the Tektro E350 Hydraulic Disc Brakes and 180mm rotors.
  • Practical range of gears. The large 50T chainring and 8-speed Shimano drivetrain worked well with the bike’s class 3 speed capabilities.
