Price and specs last reviewed Jul 12, 2026
The DUOTTS C29Max upgrades the popular C29 platform with a torque sensor, giving the 750W rear-hub motor a smoother, pedal-responsive feel instead of a basic cadence trigger. DUOTTS rates the 15Ah battery at 50 miles, though real-world range with regular throttle use runs closer to 38 miles. The 29-inch wheels and Shimano 21-speed drivetrain suit paved commuting and light gravel routes, and the front suspension fork plus 330 lb payload capacity add more versatility than a pure city bike offers. At $1,149 it competes with other torque-sensor 29ers under $1,200, though the 62 lb frame is on the heavier side for carrying upstairs.
