Positive reviews are always welcome!

Our rugged fold-and-go model is built for big fun — and small spaces.

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.

Safety certified

Rad frames are designed to meet international standards, including the guidelines set by the U.S Consumer Product Safety Commission and European Committee for Standardization.

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.

Easy to get on & off
As the smallest ebike in our lineup, you can simply step thru and ride. No need to swing your leg over the saddle — or struggle to make it over your gear.

We lightened the load
Our engineers zeroed in on reducing the bike's weight, making it even easier to fold, lift, and store.

Fearlessly fun
Dirt-caked roads, look out. Rugged fat tires help you tackle rough terrain.

An RV-ready ebike
In a tight spot? The RadExpand is a smart fit for RVs, small apartments, or anywhere else you may be short on space.
