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.
