My bike is far more prosaic. When I started a new job 15 years ago I treated myself to a new bike. It was (and still is) an Avanti rigid frame/fork MTB. Pretty basic stuff. Shimano Acera, nice alloy rims, some kind of V brakes. I've been riding that thing all this time. I'd estimate about 100km a week so around 5000km a year or around 75,000 km all up so far. I've replaced one bottom bracket, a headset, a couple of seats and grips, a set of pedals, several sets of brake blocks and lots of tyres, and the cranks because I found a nicer set.
It's totally nothing special but gets me around.
Other week, I bought my daughter a second hand almost new 24" mountain bike for $35 (retails for about $300). She loves it. Is the same brand as her previous, which we've also been rocking for 10 years and 2 kids. So I guess this one will last until she's ready for a big bike. Bikes don't need to cost the eath or be made from exotic materials to give good long service.
Happy days!
