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.

Feel natural

Experience smooth rides on any terrain with a torque sensor that responds to the way you pedal, added power for effortless hill climbing, and hydraulic disc brakes that bring you to a prompt, graceful stop.

Ride the way you want

Blaze your own trail. Versatile mid-fat tires glide over mountain paths and uneven pavement, while the adaptable class 1, 2, and 3 speed settings let you set your own pace. Add in its two frame sizes, and the possibilities are endless.

Rain or shine

No more rainchecks. With industry-leading IPX6 weather-protection and a brighter 200 lumen headlight, the Radster Trail is your go-to rainy day companion.

Radically safe

Stay safe in the saddle with rear-facing turn signals. When the ride’s over, secure your ebike by locking the controls with a fob or personal security code. And for ultimate peace of mind, the Safe Shield Battery is outfitted with thermal-resistant technology.

Raising the bar

Both the electrical system and the batteries on this model are UL listed to UL-2849 and UL-2271.

To set a new standard for ebike safety, the Safe Shield Battery features thermal-resistant technology, which means that each cell is encapsulated by a unique heat-absorbing resin designed to prevent an accident from escalating.

All eyes on you

All 2024 models feature a bright 200 lumen headlight for safer night riding and rear-facing turn signals that let cars, pedestrians, and fellow cyclists know your next move.

Ride rain or shine

Our 2024 models are built to handle the rain. With industry-leading IPX6 weather-protection, they can withstand high-pressure, heavy water splashes. And for added safety, they’re equipped with hydraulic disc brakes to ensure all-weather stopping ability.

 

Reliability on wheels

Keep the ride going. This model features a thru axle to ensure a strong, safe, and secure wheel system.
