A dual-battery option for riders whose priority is charging less often between longer rides.
The 15 Ah and 22.5 Ah packs provide 1,800 Wh in total at 48 V. Hydraulic brakes and 29-inch wheels distinguish this configuration from smaller folding formats.
Two batteries add handling and charging considerations. Measure your storage route and compare the C29 if a simpler single-battery setup is enough.
Keep the model label, serial number, battery label and charger details. For a fault, record the display message and take clear photos of the affected part. Match replacement brake pads, tyres and electrical components to the supplied version.

DUOTTS spans conventional-wheel electric bicycles, large-battery configurations and fat-tyre models. In this selection, C29Lite and E29 offer different assistance systems; C29-K adds a second battery; F20, F26 and N26 use wider tyres and larger formats. Those differences matter more than a single headline power number.
DUOTTS gives riders a choice between conventional wheel sizes, large batteries and fat-tyre formats. Compare the EU configuration before choosing. We would not choose its heavier fat-tyre models for someone who carries a bike up stairs every day.
