Technologies

Hydroforming

A specific frame-manufacturing process, where the shape of the aluminium alloy tubes is developed by the injection of a high-pressure liquid. The result is a very light, but aesthetic and strong frame.

Water-based painting process

This state-of-the-art, green technology allows manufacturing bicycles with perfect polishing in a large variety of colours. The durability of the polishing is further enhanced by the special powder coating applied on the frames at the end of the painting process. 

Integrated cable routing

The in-frame routing of the cables gives a simple, elegant, yet sporty appearance. Moreover, it protects the cables and Bowden cables against impacts from the outside, increasing the longevity of the system, thus preserving its precise operation.

ISO 9001:2009 certification

This international standard guarantees the constant impeccable quality and continuous development of the products and services, as well as customer satisfaction.

Postmount 160, 180

This well-known disc brake mounting solution has long been dominating bicycle industry. The brake body is fixed to the frame and the fork directly with two screws, parallel to the line of the frame. No more adapters are necessary due to the design, the weight of the system will not increase and the connection between the brake and the frame is as stable as possible. This system enables the simple servicing and adjusting of the brakes. The number 160 / 180 indicates the diameter of the rotor in millimeters.

The BOSCH POWERPACK 500WH batteries are designed to be as light and effective as possible for eBike users. They can be recharged fast, even partially, can be easily dismounted or recharged directly on the bike.
