The new PowerTube 625 lets you enjoy long rides and gnarly climbs while still reserving plenty of power for the next adventure. Thanks to a rated capacity of 16.7 Ah and approx. 625 Wh of power, the lithium-ion battery brings maximum ranges and altitudes within reach. The PowerTube 625 is well secured to prevent it from falling out of its housing, even on very bumpy terrain, but it is still easy to remove.
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.
The optimised frame geometry provides comfort for the cyclist even during long distances and enables maintaining an ideal posture. During designing our bicycles, we take our pick from the most comfortable accessories available on the market (e.g.: comfort grips and saddle) to represent the highest possible level of ergonomy.
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.
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.
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.
During the design process of our bikes, one of our top priorities is the safety of the cyclist. One of the most important elements of safe biking is excellent visibility, therefore, we apply the highest quality lamps and reflectors possible on our bicycles to achieve 360° visibility.
