Built with a strong aluminum alloy frame and advanced electric components, this e-bike is designed for riders who love performance and reliability. Whether you are commuting to work, exploring city streets, or going for a long weekend ride, the C29 Max gives you a smooth and exciting experience.
Strong and Stylish Frame
The C29 Max features a high-quality aluminum alloy frame that is both lightweight and strong. This material keeps the bike stable while making it easy to handle. The frame design is modern, with a clean and sporty look that stands out on the road. The full-coverage plastic fenders protect you from mud and water, keeping your ride clean even on rainy days.
This bike is suitable for riders with heights between 170 cm and 200 cm, offering a comfortable fit for taller users. The maximum load capacity is 150 kg, making it suitable for different body types and riding needs.
Powerful Motor and Battery
The Duotts C29 Max is powered by a 48V 250W hub motor (Peak Motor Power 500W) that gives you strong acceleration and climbing ability. With this power, you can easily handle slopes up to 30°, perfect for city streets or light off-road paths.
The bike runs on a 48V 18Ah battery (Dongci 21700 4500mAh cells, 13S4P configuration), which provides impressive range and performance. You can travel about 50–60 km in pure electric mode and up to 100–120 km in pedal-assist mode, depending on terrain and rider weight. The battery takes around 8–9 hours to fully charge using the 54.6V 2A charger included in the package.
Comfortable and Safe Ride
For smooth handling, the C29 Max comes with a front suspension fork made of aluminum, offering 100mm travel and a locking function. This helps absorb bumps and vibrations for a more comfortable ride. While it does not have rear suspension, the overall design ensures balance and control even on uneven surfaces.
The bike features Zoom hydraulic disc brakes with 160mm rotors and two-piston calipers on both wheels. This braking system delivers powerful and reliable stopping performance, giving you safety in all conditions—whether you’re riding in the rain or at high speeds.
Smooth Gearing and Tires
The C29 Max uses a Shimano 7-speed system, allowing you to shift smoothly and find the right gear for any road. Combined with the motor assistance, this setup ensures easy riding uphill or cruising at higher speeds.
The bike rides on 29×2.1-inch Kenda tires with reflective strips for extra visibility and safety at night. The tires have 30 TPI (threads per inch), giving a good balance between grip and durability. These large tires also provide a stable and comfortable ride on different surfaces.
Smart Display and Technology
Stay in control with the S869 LCD display, which shows important information such as speed, distance, battery level, and pedal-assist mode. You can easily switch between the six gear modes (0–5) depending on how much electric assistance you need. Gear 0 means no electric support, while gear 5 gives maximum power.
The C29 Max also supports connection to the DUOTTS mobile app, allowing you to track your rides, check battery status, and adjust settings conveniently.
Speed Options and Control
From the factory, the pedal-assist mode is limited to 25 km/h, and throttle-only mode is set to 6 km/h for safety. However, you can unlock the maximum speed up to 40 km/h by adjusting the settings (P08 value between 25–40). This gives you the freedom to enjoy faster rides when needed.
Please note that actual speed can vary depending on the rider’s weight, road conditions, and battery charge.
Lighting and Safety Features
The C29 Max includes K-code front and rear lights for night riding. The rear light also functions as a brake light, increasing visibility and safety. With an IPX4 waterproof rating, the bike can handle light rain and splashes, making it suitable for everyday commuting.
The Duotts C29 Max Electric Bike is a powerful and stylish e-bike made for modern riders. It combines excellent performance, comfort, and smart technology to make every journey enjoyable. With a long battery range, strong motor, reliable brakes, and a smooth ride, this bike is perfect for both urban and leisure riding.
