Alright, this piece of shit Bluetooth-controlled CO2 canister mounted to your hub is $4500. How much would it actually cost to diy this thing? It seems too stupidly simple; a valve to release air from the tire into the atmosphere, a valve to release air from the canister into the tire, and a teeny-computer with bluetooth to control it all. No fucking way this is anything close to $4500, right?
