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.
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
All Rad ebikes are either UL Certified or tested by ACT to comply with UL 2849.
This means our bikes and electric systems have undergone rigorous testing to meet safety standards set by UL, a respected third-party organization.
Although U.S. guidelines don’t currently require ebikes to meet UL Certification, we go the extra mile to ensure our riders feel safe in the saddle.
All eyes on you
This model features 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
Radster Trail is 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.
