The Quad Lock bracket for the brake cylinder cover is the perfect solution for attaching your mobile to the square brake fluid reservoirs of maxi scooters, scooters and motorbikes. Secure fastening: With our patented two-stage locking mechanism, you can be sure that your smartphone will stay securely attached while riding, no matter the conditions. The holder is attached to the brake fluid reservoir of your scooter with thread-locking screws. This reduces the risk of the fasteners coming loose due to thermal and/or mechanical influences, such as vibrations. Optimum viewing angle: The angle of the index head can be adjusted and the arm has several joints. This means you can flexibly adjust your smartphone to the optimum viewing angle without having to change the controls on your scooter or motorbike. The hole spacing is suitable for lengths between 38 mm and 70 mm (1.5 inch to 2.75 inch). The holder can be moved sideways when mounted on small brake cylinder covers. This ensures that your mobile is in a position that gives you full access to all controls. Elegant design: The holder for the brake cylinder cover fits perfectly with your scooter or motorbike as it is made of high-quality materials and has a discreet design.
