Double Battery. Longer Range. More Freedom.

Built for riders who want to travel farther without constantly thinking about the next charge, the DUOTTS C29-K combines a powerful motor, a 48V 15Ah + 22.5Ah dual-battery system, hydraulic disc brakes, and versatile 29-inch wheels.

With a maximum assisted range of up to 170 km, the C29-K is ready for daily commuting, longer weekend journeys, and varied road conditions. Choose the EU-compliant 250W version or the 750W International version to match your local riding requirements.

Go Further With 37.5Ah Dual-Battery Capacity

The C29-K is equipped with a 48V 15Ah main battery and an additional 48V 22.5Ah battery, providing a combined capacity of 37.5Ah.

This extended energy reserve supports up to 170 km of range in pedal-assist mode, helping reduce charging frequency and making longer journeys easier to plan. Whether you are commuting throughout the week or heading out for an extended ride, the dual-battery system gives you more freedom to keep moving.

Maximum range is based on pedal-assist use. Actual range varies according to rider weight, assistance level, speed, terrain, temperature, tyre pressure, and other riding conditions.

Powerful Performance for Every Route

48V Motor

Choose between two motor configurations:

• EU version: 48V 250W motor with a top speed of 25 km/h
• International version: 48V 750W motor with a top speed of 45 km/h

Delivering up to 65 Nm of torque, the brushless motor provides responsive assistance for commuting, inclines, heavier loads, and longer rides. Its smooth output helps make acceleration and climbing feel more controlled and less demanding.

With a maximum climbing angle of up to 30°, the C29-K is prepared for more than flat city streets.

Motor power and speed options are market-dependent. Buyers are responsible for checking local electric-bike regulations before riding on public roads.

Hydraulic Braking Comes Standard

The C29-K features front and rear hydraulic disc brakes with 160 mm rotors as standard equipment.

Compared with conventional mechanical braking systems, hydraulic brakes provide smoother modulation and responsive stopping control with less hand effort. They help you ride with greater confidence when descending, moving through traffic, or reacting to changing road conditions.

Reliable braking performance makes the C29-K better prepared for everyday commuting and longer, more demanding routes.

Three Ways to Ride

Adapt the C29-K to your route, energy level, and preferred riding experience:

• Regular cycling: Ride using pedal power
• Pedal assist: Select from five assistance levels
• Pure electric mode: Use the supplied half-twist throttle where permitted

The speed-sensor pedal-assist system offers five selectable assistance levels, allowing you to balance battery use with the amount of support you need.

Shimano 21-Speed Versatility

A Shimano Tourney 3×7-speed derailleur system gives you 21 gear combinations for tackling different gradients and road surfaces.

Shift into a lighter gear for climbs or choose a higher gear for faster, more efficient riding on open roads. A rear derailleur protector helps shield the drivetrain from accidental impacts while reducing the risk of derailleur damage and chain disruption.

29-Inch Wheels for Confident Riding

The C29-K rides on Chaoyang 29 × 2.125-inch tyres. Their larger diameter helps the bike roll smoothly across city streets, uneven paths, and mixed surfaces while maintaining a stable riding feel.

The all-aluminium single-crown suspension fork provides 100 mm of travel to absorb bumps and road vibration. A lockout function allows you to reduce fork movement when riding on smoother roads.

Clear Information at a Glance

The 2.4-inch HD display keeps important riding information easy to see. It also supports Bluetooth connectivity for use with the DUOTTS app.

Five pedal-assist levels give you quick control over motor support, while the handlebar layout places the gear controls, brake levers, half-twist throttle, headlight switch, horn button, and charging port within convenient reach.

Charge Your Phone While You Ride

A handlebar-area phone charging port lets you power a compatible mobile device during the journey.

It is a practical addition for longer commutes and extended rides when you may need your phone for navigation, communication, or access to the DUOTTS app.

300-LUX Front Lighting

The manually operated 300-LUX headlight improves forward visibility when riding in dim conditions.

Whether you are leaving early in the morning or returning after sunset, the bright front light helps illuminate the route ahead and makes the bike more visible to other road users.

Always use suitable additional safety equipment and lighting where required by local regulations.

Built to Carry More

The aluminium-alloy frame supports a maximum total load of 150 kg. A steel rear rack is included and can carry up to 25 kg, making it suitable for commuting essentials, shopping, or properly secured luggage.

The C29-K is recommended for riders between 170 cm and 200 cm in height.

Ready for Longer Journeys

The DUOTTS C29-K brings together extended dual-battery range, dependable hydraulic braking, versatile Shimano gearing, and large 29-inch wheels in one capable platform.

Ride through the working week, take on longer routes, and carry what you need with fewer charging interruptions. Choose the motor version appropriate for your market and make every ride go further.
