Switching from a car to a bicycle comes with many benefits, including a smaller carbon footprint, a healthier physique, and fewer parking tickets.
However, the threat of theft doesn’t diminish with the transition to two wheels. Bikes, of course, are much easier to steal than cars. Two students to USC hope to solve that problem with a new wheel-lock design.
Called Nutlock (via TreeHugger), the device replaces existing wheel fasteners with ones that can only be removed with a special key, which is unique to each set. There isn’t one universal design, to keep the device secure if one key ends up in the hands of a serial bike thief.
While it doesn’t secure the bike itself (a separate lock is still required for that), Nutlock at least ensure the wheels can’t be easily separated from the frame, without adding any weight to the bike.
