Price and specs last reviewed Jul 24, 2026
The DYU C9 pairs a folding aluminum frame with 20x3.0-inch fat tires for a bike that handles both apartment storage and rougher terrain. Its 48V 15.6Ah battery is the second-largest in the DYU lineup (behind only the M20's 18.2Ah pack), delivering up to 93 miles of manufacturer-rated range (60 miles practical), while hydraulic disc brakes and front suspension keep it composed on trails. At 66.1 lbs with a 264 lb payload capacity, it is built for riders who want long-range capability without giving up portability.
