In just the US, one bike is stolen approximately every 30 seconds. This amounts to around 350 million dollars in losses for bike owners every year. Bikes are easy targets for thieves and the current prevention mechanisms are simply not enough (nor practical). Lock buddy seeks to provide an extra level of protection by adding not only a proximity-activated alarm, but also a GPS system that would allow relocation, even if a bike is stolen. By this, we are hoping to add a social deterrent aspect to the traditional devices on the market (wire locks, U-locks), in addition to potential legal repercussions for a thief’s actions.
