In Urvis electric motor located in the rear wheel (hub) was used. The advantage of this solution is that the frame can be used to configure a bicycle with a ‘classic’ drive, i.e. without assistance. The maximum power of the electric motor is defined by standard EN 15194 (EPAC) and is 250W.

A cargo bike, due to its size, weight and use, should be equipped with a high-capacity battery. The Urvis Bike is fitted with the highest capacity battery available – 623Wh. The battery has been positioned vertically, to the right of the steering column, just behind the rear wall of the load compartment. Its position allows it to slide freely out of the mounting rail, e.g. for charging (charging can be done on the bike) or replacement. The controller is located behind the battery mounting rail. The range of a cargo bike fitted with a 623Wh battery is approximately 70 km – this is dependent on road conditions, the weight of the load and the weather (temperature).

Heavy-duty 1 1/8″ standard rudder bearings are used to seat the fork and steering column. The selected rudders are fitted with heavy-duty ancillary machine bearings (ACB) and 6061-T6 aluminium forged bowls. The diameter of the rear wheel axle is dictated by the type of electric motor of this cargo bike and is 10 mm. The front wheel, on the other hand, uses a 15 mm diameter through axle.

The rear uses a wheel in the popular 26″ size and the front uses a 20″ size. This makes the front part of the frame more ‘compact’ and the entire wheel and fork assembly takes up much less space. This results in a larger load space. Another advantage of the 20″ wheel is that it does not “protrude” beyond the frame contour when turning. The wheels are built on sturdy double-walled aluminium rims, in which the spoke hole slots are additionally reinforced with bushings. In addition, oversized stainless steel spokes with a diameter of 2.3 mm were used.

An interesting body solution is the lockable box:

– body material: aluminium PA11 (TIG welding (141));

– painting: polyester powder paint RAL 9005 colour;

– technopolymer hinges with opening angle lock;

– snap locks (x2 pieces);

– ABUS lock (OneKey paired with wheel lock).

StVZO cycle lights are designed to comply with German traffic regulations. With a beam shaped so as not to dazzle other road users. These lights differ from other lights in that they have a ‘cut-off’, which keeps the beam aimed directly at the road ahead and theoretically out of sight of other road users when riding at night. In addition, according to StvZO regulations, bicycle pedals must be fitted with yellow reflectors pointing forwards and backwards.
