Wall-mounted bike holder, designed for electric bikes, but it is no problem to attach other bikes as well. Due to the large weight of the bike, the rear wheel rests on the floor and the front wheel is inserted into the holder and secured with a pin made of 10mm (https://www.hornbach.cz/p/kulata-trubka-hlinikova-stribrna-o-10-mm-1m/6069573/) diameter aluminum tube, equipped with a tip for better insertion and a handle for good grip. There is a hole in the holder and handle for sealing an M3 threaded insert for attaching a string or chain so that the pin does not wander.
