DUOTTS C29-K 750W 48V 37.5Ah
Description
DUOTTS C29-K – Dual Battery E-Bike 750W with 150–170km Range
The C29-K is the long-range urban e-bike in the DUOTTS lineup. Two independent batteries — 48V 15Ah primary and 48V 22.5Ah secondary — combine for 37.5Ah total capacity and a remarkable 150–170km range. With a 750W motor, hydraulic disc brakes and 29×2.125” wheels, the C29-K is designed for riders who simply cannot afford to run out of charge.
The dual-battery system is not a single oversized pack — the C29-K uses two physically separate battery units that draw down independently and can be recharged separately. This means you can ride on the secondary battery while the primary charges at home, effectively halving your downtime on long touring days.

Dual independent batteries – why two separate units matter
A single 37.5Ah battery would be bulky, heavy, and require a very long single charge. The C29-K’s two-battery approach solves this: each unit is a manageable size, they draw down in sequence, and you can charge either one independently. On a long touring day, you can swap the depleted battery at a charge point while continuing on the other — a level of flexibility no single-battery bike can match.
150–170km range – real-world expectations
The 150–170km range is achievable at assist level 1–2 on flat terrain. At assist level 3 on mixed terrain with a 80kg rider, expect 110–130km. Even at a conservative estimate, the C29-K offers at least double the practical range of a standard 48V 15Ah e-bike — making it the longest-range option in the DUOTTS urban lineup by a significant margin.
Who Is the DUOTTS C29-K For?
Long-Distance Commuters

E-Bike Touring
Two independent batteries let you manage charging strategically across the day — charge one while riding on the other.
Riders in Areas with Few Charging Points
The largest battery capacity in the DUOTTS urban lineup, for environments where public charging is sparse or unavailable.
