Butyl rubber construction with a 0.9mm wall thickness balances durability with weight, and a 36mm Presta valve with removable core makes inflation and maintenance straightforward. Every tube is 100% inspected before leaving the factory.

I absolutely love the bike and use it nearly everyday.
I’m 67 years old but it’s a bit like going back to having dirt bikes in the mid seventies! Also 12 boards was easy to deal with. A great shop.

Belts are amazing, better price than direct from Exway (Don't deal with Exway) these belts thicker and more durable than the OEM ones too! Highly recommend.

Why Buy from Twelve Board Store
Twelve Board Store has been riders selling to riders since 2013. We are not a generic retail chain — we are a specialist board sports retailer built around genuine product knowledge, real rider experience and the kind of after-sales support that only comes from a team that actually uses the gear they sell.
Every brand we stock, we ride. Every recommendation we make comes from real experience — on the mountain, in the park, on the street, and on the road. When you call us, you talk to someone who has been on a snowboard at Hotham last weekend or a skateboard in the carpark this morning. That is the difference between buying from Twelve and buying from a warehouse with a website.
We offer services that no online-only retailer can match. Our in-store workshop handles snowboard waxing and tuning, boot heat moulding, electric skateboard and e-bike repairs and assembly, and warranty support handled in-house rather than shipped offshore to a call centre. If something goes wrong with your gear, we fix it. If your boots don't fit, we sort it. If you ordered the wrong size, we swap it — no questions asked.
Our showroom at 435A Bridge Road Richmond stocks the full range across snowboards, bindings, boots, skateboards, longboards, electric skateboards, e-bikes, outerwear and accessories. We offer free shipping Australia-wide on orders over $89, AfterPay and Zip for flexible payment, and fast dispatch so your gear arrives when you need it.
Over a decade in business. More than 1,000 reviews. The most trusted specialist board store in Melbourne. If you need advice before you buy, call us on 03 9421 2293, visit us in-store, or contact us online — we'll get you sorted.
