After riding my new MTB for a few days I realised that I only really use three out of the 15 speeds, and two of them are for off-roading- which got me thinking about singlespeed bikes. With my luck there was a budget surplus from my MTB project so I can start this one soon.
I want something that is durable, no maintenance, has good all-weather performance, and is (optional) fairly lightweight. I'm not in it for the "purist" vibe, so it doesn't need to be a fixie- singlespeed, or even internal three-speed is okay. The only things on it, apart from the bicycle standards themselves, will be a small headlamp and a small tool bag.
I really want to try this out, if only for the experience of it, but must do so on the cheap, meaning $50 or less. For reference I have racks, brakes, lights, etc in terms of upgrades already in my storage supplies so the budget would go to chains, tires, wheels etc.
Now this would mean scanning craigslist or the local goodwills for a decent looking bicycle, and then converting it to a singlespeed- that's where I need some help.
Now say I pick up a mountain bike, vintage bike, or even road bike with derailer gears. What would need to be done, all in all, to convert it to a singlespeed, or alternatively, if I find an old three-speed, how to make it fulfill the requirements of durability and versatility?
Thanks, this forum has been very helpful already.
