The World's First Inflatable, Foldable Bike Helmet
The Ventete aH-1 replaces polystyrene foam with pressurised air, so it protects like a full helmet and then folds down to less than 4cm to slide into a backpack, a pannier or a desk drawer. Independently tested by the HEAD Lab at Imperial College London, it showed a 44.1% reduction in linear brain injury risk against the best performing of 30 EPS helmets sold in the UK. Certified to EN 1078:2012 +A1:2012, CE and UKCA.
Choosing your pump option: the helmet inflates to 30psi through its Clik valve and works with any bike pump. Take it on its own if you already have a pump at home, with the hand pump if you want something to carry with you, or with the e-Pump to be inflated in under 30 seconds.
Sizing: S 51-54cm, M 54-58cm, L 58-61cm. If you are between sizes, size up and tighten the retention strap. Weight is 435g in S, 465g in M and 500g in L.
Why We Chose This for Our Customers:
- Tested at Imperial College London: the HEAD Lab benchmarked it against 30 of the best selling helmets in the UK, and it came out 44.1% better than the strongest EPS helmet in the group.
- Folds to Under 4cm: it deflates in seconds, which means it stops being the helmet you left at home.
- RHEON Rotational Protection: non-Newtonian polymer padding that stiffens on impact and spreads rotational forces.
- Built to Last: triple laminated high tenacity nylon chambers with glass fibre reinforced ribs. Swiss made, engineered in Germany, assembled in the UK.
