5 Pcs (+ 10 Caps) Brass Presta Valve Adapter - Convert Presta to Schrader/Auto for All Types of Bikes, e-Bikes and e-Scooters - Inflate Tire Using Standard Pump or Air Compressor - by Mobi Lock

Perfect for changing valve type without having to change inner tube, the brass adaptors fit very well and are very well made

Perfect! Added with ease to valves with exact fit and inflated tyres using an electric car pump. Nice easy and simple but highly effective and very low cost.

I had given up on finding a good presta pump. None of them seemed to work well so I thought I would give this adapter a try and it works well. The bag contains several (4?) presta-schrader (car) adapters plus dust caps for both types. Just open the central screw on a presta then screw the adapter on and you can use any standard car type pump. Personally I then take if off again because it might jiggle free or cause balance issues but you can just keep it with the pump. I can now pump the bike tires to high pressure with a reliable car pump. A good purchase. The worst thing is the legal disclamer "Our products are not intended to diagnose, treat, cure or prevent...Discontinue immediately if any adverse effects occur...This is not a medical device and is not intended to treated for medical use in any way. Strictly for home and personal use only." Don't know what they think people will do with them!

Why on earth have I been battling with the Presta valves on my mountain bike inner tubes for so long? These adapters screw straight over the top and turn them into Schrader valves which are so much easier to work with. Such an easy conversion. They work perfectly.

⭐️⭐️⭐️⭐️⭐️ Great product! Works as expected and I’m very satisfied with the quality. Fast delivery and well packaged. Definitely recommend!

I bought these quite a long time ago for my new bike that had inner tire tubes with Presta valves. For some reason I just continually struggled using a pump to get air into them. I sometimes wonder why Presta valves are so popular because I'm sure I can't be the only person who has an issue with them! Or am I? Anyway, so I came across these and decided to give them a go....best thing I did! They have proved to be a very inexpensive solution, are quick and easy to use converting from a Presta to a Schrader valve, and thereby saving me a lot of frustration and unnecessary stress! Highly recommended!

Nearly got me out of a hole. Borrowed a friends bike but tyres needed blowing up. They were not fitted with the correct valve stem as my compressor so ordered these. Delivered next day. Great had time to wash the bike and check everything was working in the garage. Valves arrived out on types pumped up great only to find my friend has a 36 inch inside leg and I couldn’t get the seat to adjust. Bike returned like new and he was chuffed. Oh and the valves worked a treat.

Decent quality items for the price, generally well machined but one was not and it sat at an angle on valve and didn’t hold air very well. All the others seem to be ok.

Quality manufactured product, it was received quickly and specifications were as described on Amazon

Perfectly fits the cycle mouth to convert the normal pair to bike type mouth valve. This makes it easy to fill air in any petrol pump. Surely value for money, but they can give 6 pcs instead of 5. Very easy to install and use. Good quality brass hope it will be durable.

Works great! Amazing quality. Filled tires with air no problem! 🙂

I’ve been working with different bike parts lately and what really stands out is how much of a difference quality components make in the overall ride. Even small upgrades can completely change how smooth, responsive, and enjoyable a bike feels. The drivetrain parts shift cleanly and make pedaling feel more efficient, especially on hills or longer rides. Brakes are another big one, when they’re solid and responsive, it instantly adds confidence and control in all kinds of conditions. Wheels and tires also play a huge role. A good setup feels faster and more stable, and it handles bumps and uneven surfaces way better than lower-quality parts. Even things like chains, cassettes, and cables all work together more than you realize until something feels off. What I like most is how everything connects. When the bike is dialed in with good parts, the ride just feels effortless, like everything is working in sync without you having to think about it. Overall, quality bike parts turn an average ride into something smooth, reliable, and way more enjoyable.

عملي جدا واراحني من الذهاب لمحل الدراجات لتعبئة الهواء ولكن قبل التركيب يجب فتح الصمام حتى لد'جة افرغ الهواء من الاطار ولا يتم اقفاله ويتم تركيب قطعة الوصلة فوقها لتكون الرئبسية ومن ثم يمكنك استعمال مضخات الهواء الخاصة بالسيارات بكل سهولة . شكرا لكم من قلبي
