Got this new bike and not sure how the wheels work like how they're pumped.
It's basically one hollow screw that comes out of the wheel and then a second kinda smaller one that has a little bit of rubber on it which slots into the first one.
I can pump the tyres up fully when it is just the hollow screw but when I the pump of all the air comes out within seconds.
Anyone heard of this sort of pump or know what Im supposed to do?
Got this bike off eBay
