DYU D3S

DYU D3S – compact electric bike for smooth urban commuting.

The DYU D3S is a compact electric bike for those who want to make everyday journeys easier without needing a large and heavy bicycle. The combination of a 250W motor, pedal assistance up to 25 km/h and a range of up to 50 km makes this model well suited to commuting, shorter errands and city riding. The foldable construction takes up less space at home and is practical when your electric bike needs to come along in the car or be stored in limited spaces. With 14-inch tyres, an adjustable saddle and a weight of approximately 17 kg, you get a nimble format that still offers the most important features for daily electric transport.

250W motor for efficient electric bike commuting.

The 250W motor helps you along with smooth pedal assistance and makes the DYU D3S a practical electric bike for the city's everyday journeys. The assistance reaches up to 25 km/h and the model handles gradients of up to approximately 15 degrees under suitable conditions. This makes hills and longer stretches less tiring while you still pedal and retain the feel of traditional cycling.

No throttle for natural pedal assistance.

The DYU D3S is an electric bike without a throttle, which means the motor is activated through pedal assistance when you pedal. This gives a more natural cycling feel and makes the model well suited to everyday commuting in urban environments. With a 250W motor and assistance up to 25 km/h, you get extra help on, for example, hills and longer stretches while still pedalling actively.

Up to 50 km range with pedal assistance.

An integrated 36V 10Ah lithium-ion battery gives the DYU D3S a range of up to approximately 50 km in pedal assistance mode. This gives this electric bike capacity for both daily commuting and several shorter trips between charges. Actual range is naturally affected by, for example, rider weight, temperature, surface, gradients and how much motor assistance is used. The battery has a BMS for battery management and takes approximately 5–6 hours to charge. You can therefore easily charge your electric bike during the working day or overnight and have it ready for the next journey.

Foldable electric bike that takes up less space.

The DYU D3S is developed for those who appreciate a compact means of transport. The foldable design means this electric bike can be made considerably narrower for storage, which is practical in the flat, a storage room or the car. When unfolded the model measures approximately 1170 × 500 × 990 mm and folded approximately 1170 × 200 × 720 mm. With a weight of around 17 kg it is also easier to handle than many larger electric bikes. For those who combine cycling with other forms of transport or simply want to free up more space at home, the DYU D3S provides a flexible solution for everyday life.

14-inch pneumatic tyres for comfortable city riding.

The 14-inch pneumatic tyres help the DYU D3S give a pleasant riding experience on tarmac, cycle paths and other common surfaces in the city. The air-filled tyres absorb minor bumps and contribute to this electric bike feeling smooth during everyday journeys. The compact wheel size also contributes to the model's agile format and makes it easy to manoeuvre in narrower urban environments. A suspension seat post gives additional comfort, which is especially appreciated when you use your electric bike regularly for commuting or longer rides through the city.

Dual disc brakes for controlled braking.

The DYU D3S is fitted with disc brakes both front and rear. For an electric bike used in city traffic, two disc brakes give good control when you need to reduce speed or stop. The model also has lighting front and rear for better visibility when light conditions deteriorate. The IP54 rating gives protection against dust and water splashes and makes the construction more suitable for varying everyday conditions. The combination of brakes, lighting and a robust frame makes the DYU D3S well considered for those who want to use their electric bike regularly in urban environments.

Adjustable saddle for different riders.

The adjustable saddle height makes the DYU D3S suitable for riders of different heights. The recommended rider height is approximately 160–195 cm and the recommended maximum load is 120 kg. The wide saddle and suspension seat post contribute to a more comfortable riding position, especially on slightly longer journeys. This compact electric bike has a single gear, keeping use straightforward for everyday city riding. An LCD display shows the battery level so you can more easily keep track of remaining capacity and plan when it is time to charge.

Practical features for everyday journeys.

The DYU D3S combines a compact format with features that make an electric bike easier to use every day. You get a cruise control function, clear battery indication, front and rear lighting and a foldable construction that makes both transport and storage easier. The package includes a charger with cable, battery, pedals, multi-function key, user manual and warranty card. This means you have the most important items to assemble the necessary parts and start using your new electric bike without needing to supplement with basic equipment straight away.

Choose the DYU D3S for simple and flexible commuting.

The DYU D3S suits those looking for a foldable electric bike with a 250W motor, up to 50 km of range and a compact format for city riding. The combination of 14-inch pneumatic tyres, dual disc brakes, adjustable saddle and pedal assistance up to 25 km/h makes the model practical for everything from work commutes to quick errands in the local area. The low weight and foldable construction also make storage considerably simpler than with a traditional full-size electric bike. Order the DYU D3S from Wheelyshop and make everyday commuting smoother with a compact electric transport alternative.

EU-wide rules

• Electric bikes: under Regulation (EU) 168/2013 a pedal-assisted bike with a motor of max 250 W that cuts out at 25 km/h is a bicycle in every EU country – no registration, licence or insurance. Anything more powerful or faster is a moped (L1e) with type approval, registration, licence, insurance and helmet requirements.
• Electric scooters: e-scooters are excluded from the EU regulation, so each country sets its own rules on speed, power, minimum age, helmets, insurance and registration. In most countries the limit is 20–25 km/h.
• More powerful models: a scooter that exceeds your country’s limits may only be used on private or enclosed land.
