Rad Power Radster Road vs Rad Power RadExpand 5 Plus

Pick the Radster Road for fast, long paved commutes: Class 3 assist to 28 mph, 29-inch wheels that roll smoothly, and a mid-step frame that is easy to mount. Pick the RadExpand 5 Plus if you need to fold the bike for a car trunk, apartment or train, or if you want fat tires for gravel and dirt. Both use Rad Power's 720 Wh Safe Shield battery and hydraulic disc brakes, and both are heavy at around 73-74 lbs, so neither is light to carry. Owners praise the stable ride and strong brakes on both; the Radster feels quicker and more road-oriented, while the RadExpand trades speed for compact storage and softer tires.

• Choose the Radster Road if you ride mostly pavement, want Class 3 speed up to 28 mph, and have room to store a full-size bike.
• Choose the RadExpand 5 Plus if you need a folding frame for tight storage or mixed-surface riding and are fine with Class 2 speed capped at 20 mph.
