CRISIA ALTUS 7
"Electric city bikes, as the name implies, are designed to meet all urban usage conditions and do so comfortably and safely. With 25 km/h support of electric assistance, you can easily get around the city, roll over to your workplace, arrange shopping and do it all without any special physical effort. Our Crisia bikes are equipped with Bafang drive unit, 450WH rack battery and Altus transmission.
The Max Drive System puts the rider in complete control. In spite of a generous power output and a maximum torque of more than 80 Nm, the motor operates in virtual silence. The modular motor design and integrated controller make disassembly easier and improve service responsiveness. The mid-drive motor constantly samples relevant information at a frequency of up to 80k Hz via a torque sensor and two highly sensitive speed sensors. The resulting data on crank torque, vehicle speed and pedal rotation speed is made available to the controller, ensuring precise control while achieving the highest possible efficiency.
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.
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.
