The DUOTTS C29-L Electric Bike is a powerful and versatile electric mountain bike designed for riders who want a balance of performance, comfort, and durability. Built with a lightweight yet strong aluminum alloy frame, this e-bike is ideal for urban commuting, off-road adventures, and long-distance riding. Its sturdy construction ensures stability while keeping the overall weight manageable for daily use and transportation.
Equipped with a 48V 15Ah battery using high-quality Dongci 21700 4500mAh cells, the DUOTTS C29-L delivers reliable power and long-lasting performance. The battery supports a riding range of approximately 30–40 kilometers in pure electric mode and up to 60–70 kilometers in pedal-assist mode, depending on terrain, rider weight, and riding conditions. Charging the battery takes around 7–8 hours with the included 54.6V 2A charger, making it convenient for overnight charging.
The bike is powered by a 48V 750W motor that produces an impressive 65Nm of torque, providing strong acceleration and efficient climbing ability. With a maximum climbing angle of 30 degrees, the C29-L can handle steep roads and rugged trails with ease. The factory speed settings limit both pedal-assist and throttle modes to 25 km/h for safety and compliance. However, users can unlock higher speeds by adjusting the P08 setting to 68, allowing the bike to reach approximately 45–50 km/h under suitable conditions.
For enhanced riding comfort, the DUOTTS C29-L features a front suspension fork with aluminum shoulders and aluminum legs. The fork offers 100mm of travel and includes a locking function for better adaptability across different terrains. Although the bike does not include rear suspension, its durable frame and front suspension combination still provide a smooth and stable riding experience.
The bike uses a SHIMANO 3×7-speed drivetrain, giving riders multiple gearing options for climbing hills, cruising on flat roads, or accelerating quickly. The 6-level gear mode system allows riders to customize pedal assistance according to their preference, while gear level 0 disables assistance completely. Safety is further improved with Zoom hydraulic disc brakes featuring dual-piston calipers and a power-off braking function. The 160×2.3mm disc rotors provide strong stopping power and reliable braking performance in various weather conditions.
The DUOTTS C29-L rides on 29×2.1-inch inflatable tires with 30TPI construction, delivering excellent grip, stability, and rolling efficiency on both paved roads and uneven surfaces. Front and rear flying fenders help protect riders from mud and water splashes during wet rides. The bike is suitable for riders between 170cm and 200cm in height and supports a maximum load of 150kg.
