Product Description
3 riding modes for flexible mobility
The Electric bike BK-U1 offers three practical riding modes: power mode, assist mode and bicycle mode. With assistance up to 25 km/h, the BK-U1 is ideal for daily commuting, city rides, shopping and relaxed outings.
Powerful and quiet drive
As an E-bike, the BK-U1 is equipped with a 250 W mid-drive motor specially designed for urban use. The motor operates particularly quietly and smoothly, providing a pleasant riding experience. With maximum torque of up to 70 Nm, it delivers powerful assistance and makes starting and riding uphill easier.
Comfortable equipment for everyday city use
The City electric bike features high-quality TPR grips with good elasticity and a pleasant feel. The non-slip surface supports a secure grip, while the aluminium clamping rings ensure stable fastening. The height-adjustable stem can be adapted to different riding positions using a practical clamping structure. The height-adjustable saddle also allows individual adjustment for different body heights.
Reliable brakes and good visibility
As an Urban electric bike, the BK-U1 is equipped with high-quality hydraulic disc brakes on the front and rear wheels. They provide direct and controlled braking performance and allow reliable deceleration in different riding situations. The LED lighting system with an especially bright front headlight and a safe rear light improves visibility in poor lighting conditions and in traffic.
Robust aluminium frame for versatile rides
The Trekking electric bike BK-U1 features a stable and durable aluminium frame. With comparable volume, aluminium is significantly lighter than steel, making the bike more comfortable to ride. The robust construction is suitable for both everyday city traffic and longer rides on different routes.
More safety in different conditions
The Comfort electric bike BK-U1 is equipped with pedals with integrated reflectors and a grippy surface. The structured surface supports a secure foot position, while the recessed reflectors reflect light in the dark and increase visibility. This makes the equipment particularly suitable for rides in changing light and weather conditions.
LCD display with APP and NFC functions
The Premium electric bike BK-U1 features a multifunctional LCD display that clearly shows important riding information. This includes speed, distance travelled, assistance level, battery level and error codes. In addition, the BK-U1 offers practical APP and NFC functions for modern operation and convenient everyday use.
Adjustable saddle and handlebar position
As a versatile Commuter electric bike, the BK-U1 features an adjustable stem and height-adjustable saddle. The stem can be adjusted via the integrated clamping structure without complicated tools. This allows the riding position to be flexibly adapted to different body heights and riding situations.
27.5-inch tyres for different surfaces
The 27.5×2.20-inch tyres are puncture-resistant, non-slip and wear-resistant. Their balanced width provides a stable contact area and good grip on different surfaces. The bike is therefore suitable for paved roads and cycle paths as well as varied routes beyond purely urban traffic.
Mechanically lockable suspension fork
The suspension fork of the BK-U1 features a mechanical lockout function. On flat roads, the suspension can be locked to reduce unnecessary suspension movement and transfer pedalling force more efficiently to propulsion. The mechanical lockout allows quick adjustment of the suspension to different riding conditions, supporting a comfortable and controlled riding experience.
