need to get a bike, too fat to run for more than a fortnight as it kills my shins, and I can't go swimming because they keep throwing me back in and shouting "save the whale!". nah, not that bad really, but I've got 5 stone to lose to get to my target weight.
it'll be starting out early in the year (earliest I can afford a bike) and will over the next 3 months get into a condition where I can cycle to and from work (18 miles, some long inclines/declines & starts 7am to ends 1am.)
Head is saying, road bike is best, heart is saying fixie bike as I feel it'll be better initially for getting me in shape and then I can upgrade to a road. Head is going to win, so looking for suggestions on a cheap road bike to start with and what things I should be looking for. budget £100-150 to start.
I'll be reading through all 543 pages asap and a few other cycle threads. Also, what are the laws regarding helmets? I know I should wear one, and when I start doing long distance then I would, but I'm a bit of a bugger for not wearing one around town etc if I'm just zipping around.
Also going to need some suggestions on lights + other gear, again, cheap as chips until the bug really hits and I get my bonus in April![]()
you can hardly get an ok set of wheels for that price.. even a used one for 100-150 is not going to happen.. fixie is the only plausible choice at this price and even that will probably come to peaces doing 18mile commute!

double the budget(i know that might sound like a lot) but if you do that you can get a brand new triban 3(had mine for 2 months now done 800+ miles and its been perfect)
lights will be around ~30 but then triban 3 comes with a good-ish set from decathlon anyway!
helmet well its up to you, i don't wear one(do ~23 miles a day in london) but it is risky and it is stupid so if you can and want to WEAR IT

see if you have cycle to work scheme at your work place as that would help you a LOT!
if not please do double you budget and get something that will at least do the job - if you don't you'll soon be trowing money at a rubbish bike and in the end will get a proper starters bike anyway and by doing so you'll waste even more cash.
