Tire valve extension for electric scooters and e-bikes. Comes in a set of two. Extend your tire valve by 45mm for easy access with any air pump. You'll look forward to pumping up your tires cuz you'll finally have the upper hand! There's actually nothing worse than wanting to ride and having to spend 10 minutes sweating in your gear trying to fit a hose onto your non-existant valve stem. Just get a couple of these bad boys for a few bucks, and be done with it! Keep on in your G.O.W bag and one in the shop, always good to go.
