I grew up in Florida and 3 out of my 4 beach cruiser bikes stolen… no joke. The initial shock of coming out and finding your bike, which was locked up, gone sucks big time.
Finally a smart lock… appropriately named the SmartLock. The SmartLock works like a normal lock in that you wrap it around your bike and a fixed object. The fun starts when someone tries to cut the lock as it is filled with compressed air and liquid dye. Ready for the bummer… the lock is still in concept phase… but will hopefully make it to market.
