Product Details Specifications Photos

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.

One of Rad's best motor experiences to date.

The power curves in Rad Power Bikes’ new motors make for one of the most intuitive riding experiences we’ve seen.

Safe Shield

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.

Reliability on wheels

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

Design driven

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.

Features may include:

Off-Road Tires

Rad’s classic fat tires are slimmed down to 3" mid-fat tires for better performance and sportier handling.

Torque Sensor

Experience a natural ride feel. When you pedal harder, the torque sensor kicks up the power.

Safe Shield Battery

Our all-new Safe Shield Battery is UL Certified to UL-2271. Its thermal-resistant technology encapsulates each cell with a unique heat-absorbing resin designed to prevent an accident from escalating.

Upgraded Display

Track your stats in full color, charge your device miles from an outlet, and alternate between class 1, 2 and 3 speed settings. For added security, lock your controls with the touch of a fob or a personal security code.
