My memorable bikes were a fixed solid-wheeled bike which was my first, then I had a Raleigh Mag Burner, a couple of girl-style cruisers (internal 3 speed hubs) and then later a Raleigh 10-speed road bike as a youngun, then went to an X-mart MTB when I was around 15 that lasted me through 'til I left the UK and I left it there.
I think by definition, the Raleigh bikes were fairly decent, but I've yet to really have a 'good' bike. If it wasn't for the perma-frame damage, my Centurion would be reasonable but until my IRO is built I'm in klunker-ville.
