Choosing the right DYU electric bike – a guide to the models
DYU is built on the idea that an electric bike should be easy to bring along, easy to store and easy to get started with. That is why most of the range is compact folders with small wheels, while the C6, Stroll 1 and King 750 are full-size bikes for riders who prioritise comfort or power. Here we go through what sets the models apart and what applies on European roads.
Folding DYU electric bikes for the city
Most of the models fold. The smallest are the D3S and D3F with 14-inch wheels and 17 kg. The D3F is recommended for riders of 137–167 cm and tops out at 20 km/h, while the D3S takes you up to 25 km/h and suits 160–195 cm. The A1F Pro (16-inch, 21.2 kg) and C2 (16-inch, 23.6 kg) have a rear rack, mudguards and cruise control, and the C2 also gets a central suspension. The T1 (20-inch, 22.5 kg) adds front suspension, 7 gears and a horn.
The SP1 is the lightest in the whole range: 14 kg, 20-inch wheels, 7 gears, an adjustable handlebar and a removable 24 V battery that also works as a power bank via the USB port. The C9 is the most generously equipped folder with 48 V 15.6 Ah, 83 km of range, hydraulic disc brakes, front suspension, a rear rack and a lockable battery.
Full-size models: C6, Stroll 1 and King 750
The C6 is the classic city bike with 26-inch wheels, a front basket, a rear rack, 6 gears and front suspension – 27 kg and 70 km of range on a 36 V 12.5 Ah battery. The Stroll 1 is slimmer: 28-inch wheels, 19.5 kg, 7 gears, 70 km of range and a removable battery, without suspension but with mudguards and a bottle holder. The King 750 is the range's fat bike with 26-inch off-road tyres, front suspension, 7 gears, a 150 kg maximum load and an 864 Wh battery that lasts up to 110 km. Bear in mind that the C6 and King 750 fall into the moped class in the EU – more on that further down.
Range and battery on a DYU electric bike
The stated range goes from 30 km (SP1) to 110 km (King 750), and most models sit at 40–70 km. Expect 60–75 percent of that in reality: range drops with a high assistance level, headwind, cold, hills and heavy loads. Battery size matters most – the D3S, D3F, T1 and C2 have 360 Wh, the C6 450 Wh, the C9 749 Wh and the King 750 864 Wh. Most models have a removable battery so you can charge indoors; the D3S, D3F and C2 charge on the bike. Charging takes 3–4 hours for the SP1 and up to 7–8 hours for the C9 and C6. If you want to compare with more long-distance models, see electric bikes with long range. Our practical tips to get more range from every charge apply to e-bikes too.
Motor, brakes and comfort
Most models have a 250 W motor, often with a higher peak output (C9 650 W, Stroll 1 and C2 500 W) that gives extra push at starts and on hills. Torque ranges from 10 Nm on the D3F to 75 Nm on the King 750, and the 40–45 Nm on the C2, C6 and C9 is clearly noticeable on climbs. All models are rated for a 15-degree gradient. The brakes are disc brakes throughout, hydraulic only on the C9. Front suspension is found on the C9, T1, C6 and King 750, the C2 has a central suspension and the rest ride unsuspended with pneumatic tyres that soak up the bumps. The SP1, C9 and A1F Pro have an adjustable handlebar, a rear rack is fitted to the C2, T1, A1F Pro, C9 and C6, and every model is IP54 rated with lights.
Rules in Europe for a DYU electric bike
Across the EU an electric bike counts as a bicycle (pedelec or EPAC) if the motor is rated at no more than 250 W and assists only up to 25 km/h, with any throttle limited to 6 km/h. You then ride on the cycle path without registration, insurance or a driving licence, while helmet rules vary by country. Several DYU models meet that: the D3S, SP1, C9, Stroll 1, C2, T1, A1F Pro and D3F. The C2 has a documented 6 km/h limit in electric mode; the C9, T1, A1F Pro and D3F have a throttle that you should keep within 6 km/h on public roads.
The King 750 (750 W, 45 km/h) and C6 (350 W rated, despite 25 km/h) are formally speed pedelecs or mopeds. Public roads then require registration, insurance, a helmet and a driving licence or moped permit; without that they may only be used on enclosed private land. The exact requirements vary by country, so read more about road rules in the EU, and choose a helmet whatever the class. The EU rules on pedal assistance, throttles and speed limits are explained in our guide to electric bike laws in Europe.
Service, warranty and spare parts
All DYU models come with a charger, a manual and a tool kit, and at Wheelyshop a 2-year warranty and free delivery are included. If you need tyres, brake pads, a charger or a battery, you will find parts in our spare parts portal. Simple care goes a long way: keep the tyre pressure up, charge the battery before it is completely empty and store it indoors over winter.

Frequently asked questions
Is a DYU electric bike legal in Europe?
Most of the models are pedelec class with a 250 W rated motor and assistance up to 25 km/h, and may be ridden on the cycle path without registration: the D3S, SP1, C9, Stroll 1, C2, T1, A1F Pro and D3F. The King 750 (750 W, 45 km/h) and C6 (350 W rated) are formally treated as mopeds and require registration, insurance, a helmet and a driving licence or moped permit on public roads. The details vary by country, so check your national rules.
How far does a DYU electric bike go on a charge?
The stated range is 30–110 km depending on the model: SP1 30 km, D3S 50 km, T1 60 km, C6 and Stroll 1 70 km, C9 83 km and King 750 110 km. In practice you should expect 60–75 percent of the stated figure, since assistance level, hills, cold and load have a big effect.
Which DYU electric bike is best for commuting?
For longer commutes the C9 is the best DYU model with a 749 Wh battery, 83 km of range, hydraulic disc brakes and a rear rack, and it still folds. If you commute shorter distances and combine with train or bus, the SP1 at 14 kg or the D3S at 17 kg is the easiest to carry. If you want a full-size bike with a basket and rear rack, the Stroll 1 is a good pedelec-class choice.
Are DYU electric bikes foldable?
Most of the models fold: the D3S, D3F, SP1, T1, C2, A1F Pro and C9. They have 14–20-inch wheels and weigh 14–30 kg. The C6, Stroll 1 and King 750 have a fixed frame with 26–28-inch wheels.
Are spare parts available for DYU bikes?
Yes, Wheelyshop has spare parts such as tyres, inner tubes, brake pads, chargers and batteries for DYU, and you will find them in the spare parts portal. All models come with a tool kit and a manual, and a 2-year warranty is included.
