1. [Safe and Reliable] Made of sturdy solid steel, the Iteftutne bicycle wall mount can accommodate bicycles weighing up to 66.2 lbs (27.7 kg). The surface of the rack is covered with a rubber coating to relieve pressure on the bicycle hub, wheels and speakers, thereby preventing potential scratches or damage. This vertical bicycle storage solution makes it easy to hang by optimizing gap utilization and easily storing the bicycle when not in use. It is an effective solution for residential and commercial storage applications. This wall-mounted bicycle rack is designed to be flexible and suitable for various bicycle types such as road bikes, mountain bikes (MTB), cruisers and BMX bikes, and even equipped with fenders. Please note: This storage rack is not compatible with bicycle wheels with a depth of 3.54 inches (8.75 cm). The Dorner system allows you to hang your bicycle on the wall. Insert the front wheel, lean the rear wheel against the balancer, and then rotate the bicycle wall strap to the desired angle. 4. The wall-mounted bicycle rack comes with assembly screws suitable for concrete, walls or thorn walls.
