The C29-K has a larger battery than the C29, offering the same power but greater capacity and a longer range. The newly added standard hydraulic brakes provide you with greater safety and peace of mind when choosing where you want to go.
More powerful motor
Featuring a 250W(EU version) / 750W (International version) brushless motor, this cutting-edge engine not only delivers immense power but also boasts peak efficiency, seamlessly blending speed with silent operation. Conquer uphill climbs, heavy loads, or the need for higher speeds with ease. Whether tackling urban commuting or rugged mountain trails, enjoy smoother, more effortless rides.
Range, lights, front fork
The C29-K offers three riding modes: regular cycling, pedal-assist, and pure electric. With a 15+22.5AH battery, it supports pedal-assist mode for 150-170 km. Its headlights illuminate the way forward, while its lightweight all-aluminum shock-absorbing front fork ensures a safer and more comfortable ride.
Handlebar components
C29-K's control panel features Shimano 21-speed gears, front and rear disc brakes, an electric half-handle throttle, a headlight switch, a horn button, a mobile phone charging port，and a 5-speed multifunction display. Offering precise control, the throttle ensures agile maneuvering, while the Shimano gears deliver smooth shifts for versatile riding.
Hydraulic Disc Brakes — Standard Equipment
Equipped with hydraulic disc brakes as standard, the C29-K delivers consistent and confident stopping power in all riding conditions. The hydraulic system ensures smooth, precise brake modulation, giving you better control on descents, in traffic, and during sudden stops. Reliable, responsive, and built for everyday safety, it brings confidence to every ride—no matter the terrain or weather.
22.5Ah Extended Battery
The additional 22.5Ah battery is designed to push every ride further. Working seamlessly with the main battery, it provides a deeper energy reserve that supports longer distances, steadier output, and greater confidence on extended rides. Whether for daily commuting or long, uninterrupted journeys, it reduces charging frequency and keeps you moving when the road stretches on.
Rugged Performance Assurance
Featuring a Shimano 21-speed gear system and a rear derailleur protector, the C29-K ensures a smooth and reliable ride. The protector shields against damage and chain slippage, while the gear system offers versatile options for tackling any terrain with ease.

Such a cool bike! I'm really satisfied with the range and everything else. I've tested it on regular roads, in the woods on rocky terrain, and on dirt tracks, and it performed great everywhere. Truly grateful for this machine!
It's really good, not incredibly powerful, but enough to get you where you want! It has great range and good brakes. If you run out of battery, you can always pedal 🤣
Today I’m reviewing the C29k Duttos bike🔥
First of all, the design looks very stylish and gives a premium feel. When you ride it on the road, it definitely stands out 👌 In terms of performance, the bike is very smooth. The engine response is good, and even on long rides, you won’t feel much vibration. It’s a great choice for those who want comfort. One of the best things is the battery backup ⚡
Once fully charged, it lasts a long time, so you don’t need to charge it frequently—perfect for daily use. The braking and control are also very good, which gives you confidence while riding in the city. Overall, the C29k Duttos is a smooth, comfortable bike with long battery backup—an excellent option for anyone who wants both style and performance 💯
Très satisfait de ce vélo à un prix imbattable.
Les 2 batteries sont un vrai plus, même si la conduite avec la batterie arrière nécessite une plus grande "précision" de conduite (en raison du poids supplémentaire) surtout dans les ronds-points.
The product is very satisfying and the battery time with double battery you really got some serious kilometers. I'm also planning to buy another model wich comes with double motor for different power ride and fun. Thanks
