DUOTTS C29-K 29" Long-Range Electric Bike 750W Dual Battery

The DUOTTS C29-K combines a 48V 15Ah main battery with a 48V 22.5Ah extended battery. Together they provide 1800Wh of capacity and support longer journeys than a conventional single-battery commuter electric bike.

Yes. The International Version can be configured to a restricted 250W motor setting with assistance limited to 25 km/h. Riders should still check the applicable electric-bike requirements in their country before using it on public roads.

No. The DUOTTS C29-K uses a 100 mm front suspension fork without an independent rear shock, and its 29 × 2.125" tyres are narrower than conventional fat tyres.

The DUOTTS C29-K is designed for riders between 170 and 200 cm who regularly cover longer distances and want a commuter electric bike that can also handle gravel and light off-road routes.

The Shimano 21-speed drivetrain provides a broad gear range for hills, cruising and unassisted riding. Hydraulic disc brakes provide smoother modulation and more consistent stopping control than typical mechanical systems.

DUOTTS C29-K Long-Range Dual-Battery Electric Bike

The DUOTTS C29-K combines a 750W brushless motor with two 48V batteries for riders who need extended range without sacrificing practical daily performance. Its 29" wheels, front suspension, hydraulic brakes and rear rack make it suitable for commuting, longer leisure rides and mixed road conditions.

750W Motor with Adjustable Limits

The International Version uses a 48V 750W brushless motor producing up to 65Nm of torque and supporting speeds up to 45 km/h. The system can also be configured to a restricted 250W and 25 km/h setting when lower motor output and assisted speed are preferred.

1800Wh Dual-Battery System

A 48V 15Ah main battery works with an additional 48V 22.5Ah battery to provide 37.5Ah and 1800Wh of total capacity. This dual-battery arrangement supports up to 200 km in pedal-assist mode while helping reduce charging frequency on longer routes.

29-Inch Wheels and Front Suspension

Chaoyang 29 × 2.125" tyres roll efficiently across paved roads while providing stability on gravel and light trails. The 100 mm lockout suspension fork absorbs impacts from uneven surfaces and can be locked for more efficient riding on smoother roads.

Hydraulic Brakes and 21 Speeds

Front and rear hydraulic disc brakes with 160 mm rotors deliver smooth, controlled braking in urban traffic and on descents. The Shimano Tourney 3×7-speed drivetrain gives riders a broad gear range for climbing, cruising and riding without motor assistance.

Connected and Practical Equipment

A 2.4" HD display connects to the DUOTTS App through Bluetooth, while the half-twist throttle, five pedal-assist levels and phone charging port keep essential controls within reach. A 300 LUX headlight, mudguards and a steel rear rack with a 25 kg load rating add everyday practicality.

With its extended dual-battery range, efficient 29" wheels and practical commuter equipment, the DUOTTS C29-K is designed for riders who regularly cover longer distances and want flexibility across city roads and light off-road routes.
