Know what fits your ride.

For riders prioritising a large battery and suspension over carrying convenience.

A substantial small-wheel platform

The 52 V / 27 Ah battery provides a calculated 1,404 Wh. Full suspension and hydraulic brakes support the model’s substantial 20-inch-wheel format.

Before you choose

Small wheels do not make this a lightweight or folding commuter. Measure access to storage and compare the F26Lite if a simpler configuration is more suitable.

Why this brand is here.

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.
