Built a bike for the commute to Uni in London a couple of years ago. Best thing I ever did, lovely ride along the canal is a perfect way to start the day! Have seen an increasing amount of the monowheels around. They look like fun!
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.
