Two batteries for longer routes

The C29-K combines a 48 V 15 Ah frame battery with a 48 V 22.5 Ah rear battery. Their combined nominal energy is 1,800 Wh. The aluminium frame, 29 × 2.125-inch tyres and hydraulic disc brakes provide a conventional bicycle format with additional battery capacity.

  • Dual 48 V batteries
  • 29 × 2.125-inch tyres
  • Hydraulic disc brakes

Battery, range and storage

The supplier specifies approximately 150–170 km in pedal-assist mode. That is a manufacturer estimate, not an ortlux range test. Two batteries also mean more weight and two charging routines: allow 7–8 hours for the 15 Ah pack and 6–7 hours for the 22.5 Ah pack with the specified chargers.

Before you choose

Measure your storage space and check whether you need to lift the bicycle. Compare battery capacity and carrying weight together, rather than choosing from the longest range figure alone.

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.
