29" electric bike with 1,800 Wh battery and 170 km range – DUOTTS C29-K

This version of the C29 boosts the battery to 1,800 Wh, making it one of the longest-range bikes in our range: 130 km real-world or more. It includes dual chargers and hydraulic brakes. It's for very long journeys or for charging just once a week.

Guide price: €1,249 (VAT included). See the full data in the specifications on this page.

Estimated real-world range

The manufacturer claims up to 170 km, measured with minimum assistance, flat ground and a light rider. In normal use (medium assistance, a 75–85 kg adult, some hills and stops) we estimate between 129 and 180 km per charge, based on 10–14 Wh/km with its 1800 Wh battery. With maximum assistance, cold weather or steep climbs, expect the lower end of the range.

Example: for a 10 km commute each way, you would need to charge it roughly every 6–9 working days.

Who is the DUOTTS C29-K for?

• Tall riders and longer trips: the big wheels roll better and hold speed with less effort.
• Heavier riders or loads: rated up to 150 kg.
• Riders who value braking: hydraulic disc brakes stop with little effort and need less adjustment.
• High-mileage riders: the large range means charging only a few times a week.

Do you need a licence or number plate?

No. With 250 W rated power and assistance up to 25 km/h, it is treated as a bicycle in the EU: no licence, no registration and it can use cycle lanes. In Spain helmets are compulsory on interurban roads and for under-16s everywhere.
