Folding step-through electric fat bike 20" with 748 Wh – Cyseekin C20

The C20 is Cyseekin's go-anywhere folding bike: a step-through frame so you can get on and off without lifting your leg, wide 20 × 3.0 inch tyres and a suspension fork for a comfortable ride over cobbles, gravel or dirt tracks. Its 250 W rear hub motor delivers 60 Nm, the removable 48 V 15.6 Ah (748.8 Wh) battery is among the largest at its price, and hydraulic disc brakes stop it with little effort. It has Shimano 7-speed gears, a colour LCD display, built-in lights and mounting points for a basket and rack. It weighs about 30 kg, so it folds for the car boot or a storage room rather than for carrying.

Guide price: €1,184 (VAT included). See the full data in the specifications on this page.

Estimated real-world range

The manufacturer claims up to 120 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 53 and 75 km per charge, based on 10–14 Wh/km with its 749 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 2–3 working days.

Who is the Cyseekin C20 for?

• People short on space: it folds for a car boot, a small storeroom or a corner of the flat.
• Tracks, sand, gravel and broken tarmac: the wide tyres soak up bumps and grip well.
• Heavier riders or loads: rated up to 150 kg.
• Riders who value braking: hydraulic disc brakes stop with little effort and need less adjustment.

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.
