Single Speed Bikes?

You need either horizontal dropouts or a chain tensioner so the chain doesn't lock up and throw you over the front. I don't know much about fixies though. My expertise lies with dirtjumper and street bikes. I'm thinking it would be similar though. It's almost impossible to build a single speed out of old parts. Especially if you don't have the right tools. (chain whip, cog key, chain break tool etc...) It only cost me around $55 to convert my bike into singlespeed which included a new master link, tensioner and labour. Just take it to your local shop.

all you need is a single speed conversion.. http://www.performancebike.com/bikes//CatalogSearchResultView?storeId=10052&catalogId=10551&langId=-1&pageSize=16&beginIndex=0&sortBy=Dollar+Rank%2F%2F1&searchType=resultSet&cn1=&searchTerm=single+speed+conversion

i dont have a bike to sacrifice thats why i was asking if you can build one the same way you build fixies. it seems fun to be able to customize a bike like that. thank you though

get a cheap old frame, then you can put any parts you want on it. usually it will be about 200 for everything you need (the cheapest ishh) maybe a bit more

They are called fixies you noob

no single speed bikes you can coast. fixies the pedals rape the back of your legs if you stop pedaling

oops only saw your first post. i too am sorry
