I also got a punk… Bike with extra air in the frame

Choka is a bicycle with a structure that stores excess air in a tube inside the bicycle frame and presses the hose to allow air to flow through the tire when a puncture or air decreases.

The internal air system has the capacity to inflate 2-3 tires once replenished. Equipped with a safety valve that prevents excessive refilling, it can always fill the optimum amount of air. In addition, a hook that wraps the hose outside the frame does not normally interfere. There are two types in all. These are models for hard trail MTB (AGHATA) and off-road models (GRAVAËL).

This product also raised funds through Kickstarter, a crowdfunding site. More information on the product can be found here .
