2025 Rad Power Bikes RadExpand™ 5 Electric Folding Bike

Fold in to store. Fold out to explore.

Our fan-favorite folding ebike has fat tires to tackle adventures and a small profile for easy storage. Featuring a step-thru frame, you can customize your ride with adjustable handlebars, seven speeds, and four levels of pedal-assist.

I love the fact that this is such an approachable and affordable bike.

The most exciting e-bike of 2022 is way cheaper than you’d expect.

Safety certified

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.

See and be seen.

Safety is paramount to Rad engineers. Reflective striping is incorporated on tire sidewalls, plus LED headlights and taillights come standard on every model.

Precision in practice.

Every eike receives a thorough 50-point inspection before it reaches your door. How in-depth is it? Even the screws are double-checked.

Brake confidently in any weather conditions.

Ride rain or shine. Every ebike comes with brakes tested for all-weather stopping ability.

Features may include:

Included rear rack

No need to purchase a separate rack - the high quality included rear rack complements the bike's 275-lb. payload capacity.

Geared hub motor

Climb hills and zip across intersections powered by our Rad-engineered 750W motor, designed in-house to help you go steeper at lower speeds.

Folding mechanism

A custom folding mechanism helps you fold your ebike for storage and easy travel.

Handlebars

The adjustable riser bar allows you to personalize your fit, with handlebars that move in and out for comfort.
