You’ve never had a commute this good.

The Radster Road isn’t just the best commuter bike, it’s the perfect commuter bike. It can get you up to 28 mph when you’re running late, give you enough range to cover your entire town, and keep you feeling great for hours — thanks to two ergonomic frame options that prioritize rider comfort. And the best part? It’s just as fun and capable when the weekend rolls around.

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

Built for your well-being: When you're in the saddle, you're in good hands. The Radster Road is equipped with a full suite of safety features, including dual turn signals, a brighter 200 lumen headlight, and a Safe Shield battery with thermal resistant technology.

An extra touch of security: With just the touch of a fob or a personal security code, you can lock your bike’s controls to prevent others from powering it on. Use it with the bike lock of your choice to provide an added measure against theft.

Features may include:

Turn Signals

Let cars, pedestrians, or fellow cyclists know your next move with rear-facing turn signals.

Turn Signals

Safe Shield Battery

One-Touch Fob Security

For an extra layer of security, you can lock and unlock your bike’s controls with the touch of a fob or a personal passcode.
