For riders comparing a conventional 29-inch bicycle format with fat-tyre alternatives.

A familiar full-size starting point

The single-battery configuration uses 48 V / 15 Ah. Shimano 3×7 gearing offers a wide choice of ratios; the source distinguishes C29 mechanical brakes from C29L hydraulic brakes.

Before you choose

Choose the exact brake/version combination carefully. Compare C29-K for dual batteries; the manufacturer’s conflicting weight figures need resolving if you plan to lift the bike frequently.

Range context: Manufacturer pedal-assist range estimate; not an ortlux road test. Rider mass, assistance level, terrain, temperature and tyre pressure affect the distance.

Configuration notes: C29 and C29L share the source page. Their brake specifications differ. The battery and brake equipment must match the selected version.

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.
