About
What it is.
The RadExpand 5 is a folding e-bike from Rad Power Bikes, built on a 6061 aluminum frame with a low-step shape and a steel fork. Its 20-inch knobby fat tires and rigid suspension suit cityscapes, fire roads, and dirt trails alike, while the folding mechanism and saddle lifting handle collapse it to a compact footprint for storage or transport.
A 672-watt-hour battery drives the pedal-assist system, with a top speed and per-charge range positioning it for both commuting and longer recreational rides. Aluminum crank arms, handlebar, and seat post keep weight manageable despite the load capacity, and the adjustable-angle display accommodates riders across a range of heights. It's built for adults who want one bike that folds for an apartment or a car trunk and still handles varied terrain.
The verdict
The RadExpand 5 ranks second among folding e-bikes and delivers strong comfort and battery life for urban commuting, but widespread reports of tire punctures and controller failures—plus inconsistent customer support—undermine its reliability promise at $1045–$1599.
