2025 Rad Power Bikes RadExpand™ 5 Plus Electric Folding Bike

The folding bike. Gone futuristic.

We’ve taken the classic RadExpand folding bike and enhanced it with all-new tech, impressive range, and a collection of features that make it more comfortable, capable, and unique. Tackle tougher terrain with a hydraulic front suspension fork, and enjoy smoother rides wherever you wander with the all-new torque sensor that responds to the way you ride.

One of the Best Folding E-Bikes We've Ever Tested.

Better handling over nearly all other folding ebikes we've tested.

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. 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 bolt-on axle to ensure a strong, safe, and secure wheel system.

Design driven

Comfortable & versatile: Effortlessly traverse city streets, rugged trails, and steep hills. The hydraulic front suspension fork smoothes out your ride, while the responsive torque sensor delivers added power when you pedal harder.

Safety. Expanded: Whether your ebike’s on the road or stowed away, the Safe Shield Battery features anti-thermal technology for extra protection. And for even safer rides, the RadExpand 5 Plus boasts rear-facing turn signals and fast-acting hydraulic disc brakes.

Take it anywhere: The RadExpand 5 Plus conveniently folds-up for easy storage in cramped apartments, RVs, or the trunk of your car. To save you even more space, we’ve equipped it with new collapsible pedals.
