2007 hasn’t been a good year for cycling, at least not for me. I recently made a birthday resolution that in 2008 I would ride more.

Along with riding less, I’ve paid less attention to bike technology, which is something that’s always interested me. Lately I’ve been paying a little more atention. I just read about a prototype bike-computer/rear-view camera called Cerevellum. This looks like a great idea—plug-in modules for different functionality. One idea I’ve never seen implemented on a bike is a crash camera. Now, this might be more of a concern for me than most people, but the overhead would be slight and the potential benefits considerable.

I envision the system including rearward-looking and forward-looking cameras, an accelerometer, and some flash-memory storage. It wouldn’t need much—just enough to capture about a minute’s worth of video and audio (about 180 MB for good-quality uncompressed video—chump change by today’s standards). If the accelerometer detected any sudden movement (indicative of a crash), the cameras would save the preceding 30 seconds and the following 30 seconds. That should be enough to capture license plate numbers, the circumstances of the crash, etc. A manual trigger to save would also make sense, as would manual still photography capture. Equipment like this does exist for cars, but nothing miniature enough for a bike. With 1 GB memory cards as common as dirt, one could record several minutes of footage per ride, as well as a lot of still photos, which could be interesting in ways other than crash documentation.
