Fand ich auch ärgerlich. Es gibt Schläuche mit abgeschrägtem Ventil. https://www.brack.ch/vmax-schla...

Well, I think that you should get more information before you judge. I have been in possession of this monster device for just under 2 weeks. Of course, I also asked myself how the pumping works. When I was at a loss, I went to Vmax Global in Rothrist. I made an appointment (Corona technical) and they explained the whole thing to me and pumped up the wheels for the first time free of charge and also explained the display above. Very friendly team, I was very satisfied! Can only recommend it to everyone!

Loosen the black screws at the front and rear of the brake discs so that you can push the brake disc to the side and get to the valve better. (5 screws as I remember) To get to the black screws at the bottom there is an opening where the wheel is attached and there is room for a screwdriver or cordless drill. Carefully remove the rubber seal at the back with a flat-blade screwdriver to get at the screws. After pumping, screw everything back in place and that's it.

Not at all, I've tried every possible way. They even sent an extra hose, it simply doesn't work. I sent it back. The product is useless if you can't even do something as simple as pumping yourself. I still maintain that the wheels are mounted incorrectly, if the valve wasn't directly behind the disc brake, it would work wonderfully...

As they say, they have the products, but we have to live with them... :(
