I take a totally different approach. Nothing on the bike. (Well, I have a computer so I can ride the trainer and motivate myself to actually do something.) But on the road its nothing. But I've lived the same place 22 years. I have regular routes. All mapped on on Thomas guides and entered into an Excel worksheet. Then I make a page for each year, line for each day and columns for bike, mileage, elevation, route, comments, mechanics or fix gear ratio. Sum each bike separately plus fleet totals.

Most of the time, it is just a small amount of work, but every once in a while, I get to have real fun in a geeky sort of way. 5 years ago I realized that I was within a year or so of hitting three milestones, 200,000 lifetime miles, 100,000 geared miles and 100,000 fix gear miles and that if I stepped up my fix gear riding just a little, I could hit all three on the same day. June 4 years ago I rode about 40 miles, roughly half on each bike and did it.

I cannot keep track of bike computers. keep them charged and working and keep 5 bikes equipped. One Excel worksheet works.
