Hello everyone 😊 I bought this part a few weeks ago. Fully satisfied. Until the question about tyre pressure came up. I have three left hands, sorry 😔. I've now bought an easy pump from Bosch, except that half the air is always out straight away. Otherwise great part❗ Seen on sale on VMAX (don't understand a word about Dunlop etc...): the valve adapter makes it easier to inflate your e-scooter. Thanks to the valve adapter, your e-scooter is easier to inflate. Thanks to the recoil bolt, very little air escapes when the adapter is removed. The adapter can be easily operated with conventional hand pumps and electronic compressors. The adapter is not suitable for inflating at a petrol station. very little air escapes when the adapter is removed. Does anyone know what I would need? A connecting valve from the Bosch Easy Pump (which actually connects directly to the VMAX valve) with a "recoil bolt" so that I don't have to pump three times thanks to the different air BUT BUT BEFORE ALL never know exactly (which apparently can even be dangerous) how much BAR pressure my tyre has inside? Many thanks to the person who answered 🙏🙏🙏🙏 Christian
