140mm Brass Auto Tire Valve Extension Adaptor, Air Tyre Stem Extender Inflation Stright Bore for Motorcycle, Bike, Mower and Scooter(140mm)

Needed to inflate electric scooter rear tire

Very good tool especially if you can’t reach the stem with the nozzle

Works perfectly! Nice product!

I used it for my scooter and it is very good to work with.

Works like it should, good quality and arrived fast.

easy to get air in

Works good

I got this to use with my Niu KQI3 Max electric scooter, the rear wheels valve is really hard to reach with your fingers and when pumping the tires, removing the pump causes a significant amount of air loss since it takes a while to unscrew (due to it being hard to reach). With this I can screw it on and quickly screw it off as it extends out a good enough distance from the wheel. Highly recommended if you are in a similar situation.

This is a well made product. I bought the 100mm size figuring it would easily clear the E450 front hub caps. It is long enough but the nut up near the top used to tighten it where the hub cap cutout is. I replaced this with the 140mm size made by the same company. Just be sure you know where that nut will be before deciding what length to purchase.

This was my 3rd attempt at getting an extension valve that would work with my electric unicycle’s tire and I’m happy to say it works perfectly! Excellent build quality.
