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.
