FAQs
Which version is this?
This is the supplier-listed 750W C29-K international configuration with 48V 15Ah and 22.5Ah batteries. EU warehouse stock does not make it the separate 250W EU edition.
How much battery capacity is fitted?
The two 48V batteries are rated 15Ah and 22.5Ah, totalling 1800Wh nominal. Replacement batteries must match the exact mounting, connectors and electrical specification.
How long does charging take?
The manufacturer lists approximately 6–8 hours and 54.6V 2A plus 54.6V 3A charging equipment. Follow the supplied instructions and match each charger to its intended battery.
What brakes does it use?
Hydraulic disc brakes are specified front and rear, with 160mm rotors. Match replacement pads and hydraulic service parts to the delivered brake assembly.
Which tyres are specified?
29 × 2.125-inch Chaoyang tyres with inner tubes. Check sidewall markings, rim size and valve before ordering replacements.
Does it have suspension?
A front suspension fork with 100mm travel and lockout is listed. A rear shock is not specified.
What gears and pedal assistance does it have?
Shimano Tourney 3×7-speed gears are paired with speed-sensor pedal assistance, using levels 0–5.
What can the rear rack carry?
The manufacturer lists a 25kg rear-rack limit and a 150kg total loading limit. Those are separate limits; account for the fitted rack battery and follow the supplied loading instructions.
Is the advertised range guaranteed?
No. Distance changes with total load, assistance, speed, gradients, temperature, tyre pressure and battery condition.
Is this approved for public roads everywhere?
No. A 750W specification and EU stock location are not proof of road approval. Check local rules and the exact delivered configuration before riding.
DUOTTS C29-K 750W Dual-Battery Electric Bike

Its 29-inch wheels, hydraulic disc brakes and Shimano 21-speed gears suit riders looking for a large-wheel, dual-battery configuration.

An aluminium frame, 100mm-travel front fork with lockout and 2.4-inch Bluetooth-enabled display complete the listed equipment. Net weight is 32.5kg and dimensions are 1860 × 1080 × 680mm. The maximum load is 150kg overall, with a separately specified 25kg rear-rack limit.
About DUOTTS
DUOTTS offers electric bikes across city, trekking and wider-tyre ranges. The C29-K is part of its C29 family, using two batteries rather than a single pack.
DUOTTS offers distinct regional motor versions, so model name, power, battery combination and supplied edition should be checked when comparing bikes or choosing replacement parts.
