Can't get my flickr account to work.
I've attached them below.
I call it The Rat Bike, its served me well for the past two maybe three winters. Its great fun, with a nice easy gear so can easily slow down brakeless (42-16). It wheelies really well and once you've learnt that, bar spins are a good laugh. I built it as a winter beater which takes on anything, good for riding across grass land and then back onto roads etc. Looks like a heap of crap so unlikely to receive any unwanted attention, but at the same time I think it looks really cool!
Its an old Ralliegh MTB frame that I had shot blasted. I built up some Halo Freedom Disc 26" rims onto system ex hubs, so they're strong and light. Its got Park Identiti Forks with a disc mount so you can run a brake if necessary. The bars are old S&M race bars that I ground down. It has an FSA pig headset. And the rest was out of the parts bin from old fixed gears/MTBs I had. Oh nearly forgot, it has Odessey Plastic Pedals and some awesome foot straps which I bought off someone on here.
Not really given a price much thought but figured £150 yesterday evening. Somewhat over your budget but there are actually some quality parts on the it. There is some surface rust near the bottom bracket as I ground all the paint back and then clear coated it with a rattle can, must have missed that area. I give it coat about this time each year before winter and then grind the flakey bits off after winter and repeat.
Let me know your thoughts!
