I have never liked computer games, but with the influence of the Co-Habitant I am finally starting to get into them.
putting one of these on his own bike, he decided that I was just jealous and got me one for Graham (my Rivendell Sam Hillborne). I reluctantly agreed to try it, and quickly grew to love it - much to my dismay, as there is really no attractive way to attach these things to a bike.
For those not familiar with it, a bicycle computer is basically a speedometer with some extra features. Mine tells me: distance covered during a trip, current speed, maximum speed during a trip, average speed, and total distance covered so far (since installing the computer). There is also a clock, which is handy since I don't wear a watch and extracting my mobile phone requires stopping the bike. If you are training yourself for touring, the bicycle computer helps you measure your progress in terms of how fast you are able to cycle. Keeping track of the distance you have covered is also useful. My top speed so far is 27.4 mph (44.1 km/h), which I reached the other day on the hills in Maine. I know that to the roadies out there, this is far from impressive. But for me, it was shocking to learn that I was capable of cycling this fast. 27.4 mph is of course a downhill speed, but on flattish ground I was consistently cycling at 16-19 mph.
