I start with a walmart bike, had the bb and other parts creaking and crackling within 2 weeks of daily riding... so I got rid of it and got a 86 schwinn world sport and fixed it. I rode that for 4 months and it was awesome. Went through some crank arms ( learned that 170mm cranks do not work well with my desired lean angles ! ) ...
Then I killed the hub on it by over-tightening it and so I put the original 7spd wheel on it and gave it to a friend of mine as a ss with a front brake...
Then I got myself an ebay special 24spd road bike (chromoly steel)...
I've been riding that for another 2.6 months... (currently still riding it)..
it looks like this but in british racing green and it says " dawes lightning dlx " on it instead of motobecane but its 100% the same bike with the same sorry "sora" components..
=)
I Have ordered a few little things for it here and there but I have not installed them yet... dura-ace 9psd rear deraileur, new wheels, ultegra 9spd cassette, dura-ace 9spd chain... etc I cant wait to get it all setup so I can get the chain to actually stay on the gear I put it on when I sprint !!
