As long as bicycles have existed, those who wish to steal said bicycles have found new and inventive ways to get around whatever locking mechanisms are put in place to keep them safe. As a result, lock manufacturers have to come up with new ways to ensure their products do what they're supposed to: keep the locked bike from being stolen. Among all the different designs, the U-style lock has widely been adopted as the best and overall strongest.
I recently took up bike riding as a good way to get outside and get active. Being a tech-junkie and overall stat-lover, though, I immediately wanted a good way to track my rides in detail, including real-time MPH, distance traveled, and all the other info that may help me better keep up with my progress. Instead of going the traditional "bike computer" route, though, I decided to use my smartphone to accomplish the task at hand.
