Duotts C29-K

Duotts C29-K – the electric bike where range meets raw power.

Looking for an electric bike with long battery life, a strong motor and reliable comfort for both commuting and adventures? The Duotts C29-K is built for riders who want to cycle further, more confidently and more flexibly. With dual batteries totalling 48V 15+22.5Ah, a powerful 750W motor and up to around 150–170 km of range in pedal-assist mode, this is an electric bike that takes you all the way – and a little further. In pure electric mode, the range is around 90–100 km under favourable conditions.

Whether you commute every day or explore new routes at the weekend, the C29-K delivers stable performance, clever technology and well-thought-out design in every detail.

Dual batteries for maximum range.

One of the biggest advantages of the Duotts C29-K is its dual battery system. The combination of 48V 15Ah and 22.5Ah provides a range of around 90–100 km in pure electric mode and up to around 150–170 km in pedal-assist mode under favourable conditions. Actual range is affected by factors such as terrain, temperature, rider weight, speed and riding style. That means fewer charges and more freedom in everyday life.

If you are looking for a long-range electric bike for commuting or longer rides, this is a solution that minimises range anxiety. The batteries are removable, making charging flexible whether you live in a flat or a house. With dual charging ports, you can also optimise charging time and get back on the road faster.

750W motor with 65Nm of torque.

The brushless 750W motor delivers powerful, smooth drive with 65Nm of torque. This gives you quick acceleration and confident performance on climbs with gradients of up to 30 degrees. Whether you are carrying luggage on the rear rack or riding in hilly terrain, you get stable and controlled drive.

The top speed is 25 km/h.

Hydraulic disc brakes for safe riding.

Safety is central to the Duotts C29-K. The electric bike is equipped with hydraulic disc brakes front and rear with 160 mm rotors. Hydraulic technology provides smooth, precise braking and better control during sudden stops.

In city traffic, on descents or on wet surfaces, the braking system gives a confident and responsive feel. It is an important detail if you use your electric bike every day and want full control in every situation.

Comfort for both city and terrain.

With 29-inch pneumatic tyres from Chaoyang and a shock-absorbing aluminium front fork with 100 mm of travel, you get a stable and comfortable ride. The front suspension absorbs bumps effectively and makes cycling smoother, whether you are riding on tarmac, gravel or light forest trails.

The Shimano 21-speed drivetrain gives you the flexibility to adjust pedalling resistance to terrain and pace. Gear changes are smooth and precise, so you can easily find the right rhythm both in town and in hillier landscapes.

Three riding modes and a smart display.

The Duotts C29-K offers three different riding modes: regular cycling, pedal assist and fully electric mode. In fully electric mode, the range is around 90–100 km, while pedal-assist mode can deliver around 150–170 km under favourable conditions. This gives you the freedom to choose how much you want to contribute yourself and how much you want the motor to do.

The 2.4-inch HD display shows speed, battery level, assist level and total distance. The display is Bluetooth-enabled and can be connected to the Duotts app to record your rides for a more connected experience. The electric horn also makes it easy to alert people around you while riding.

Practical details that make everyday life easier.

The sturdy aluminium frame is built to handle a maximum load of up to 150 kg. The steel rear rack carries up to 25 kg, making the electric bike ideal for commuting with a bag, groceries or extra equipment.

The integrated 300 LUX headlight ensures good visibility in the dark, and the IPX4 rating protects against rain and splashes. The ignition key provides extra security and the battery box is easy to handle. With a recommended rider height of 170–200 cm, the C29-K suits most adult riders.

The built-in USB port on the handlebar lets you charge your phone while riding, which is perfect if you use GPS or fitness apps on your rides.

Built for long-lasting use.

Weighing 32.5 kg, the Duotts C29-K is a stable and robust electric bike that inspires confidence. It is CE-certified and designed to operate in temperatures between -10°C and 40°C, making it a reliable choice all year round.

The package includes, among other things, a charger, tool kit, pump, two batteries, front and rear mudguards, rear rack and user manual. You get everything you need to get started straight away.

EU-wide rules

• Electric bikes: under Regulation (EU) 168/2013 a pedal-assisted bike with a motor of max 250 W that cuts out at 25 km/h is a bicycle in every EU country – no registration, licence or insurance. Anything more powerful or faster is a moped (L1e) with type approval, registration, licence, insurance and helmet requirements.
• Electric scooters: e-scooters are excluded from the EU regulation, so each country sets its own rules on speed, power, minimum age, helmets, insurance and registration. In most countries the limit is 20–25 km/h.
• More powerful models: a scooter that exceeds your country’s limits may only be used on private or enclosed land.
