The DUOTTS C29-K is the long-range sibling in the C29 lineup: a 750W rear-hub motor and a large 20Ah battery push manufacturer-claimed range to 90 miles, with a more realistic 65 miles in mixed everyday riding. Its 29-inch wheels roll faster and smoother over pavement and light gravel than smaller-wheeled alternatives, while a Shimano 21-speed derailleur and throttle give riders full control over how much they pedal versus coast. At 64 lbs with a 330 lb payload rating, it is built more for commuting and recreational road riding than off-road use, and the front suspension takes the edge off rough city streets and bike paths.
