You built your own bike? What made you decide for building over just buying?
Mainly, I wanted to be able to fix it when it went wrong! I thought building one would ensure that when bits went wrong I'd know exactly how to make it right. It certainly wasn't profitable. Even buying all the parts second hand, I spent about £250 on a bike that I could probably only sell for £200 if I'm lucky! No regrets though - learnt a lot, can fix it with my eyes closed now and got a great sense of achievement from the project! Plus - the tools I bought as part of the budget will continue to come in handy.
Oh yes, you can fix almost anything on a bike yourself if you spend some time with it. I grew up with bikes, so I'm always baffled when people fail to do the simplest things like replace or fix flat tires or worn out brakes.
