>>1021239>not many hills, small hillsyou'd be fine with a fixed gear, but just for convenience stopping/starting at lights it may be nice to have a derailer
>flip flop hubmany new bicycles meant to be run fixed gear and kits available for converting old bikes to fixed gear have rear hubs (the bit in the middle of the wheel) that have a fixed gear on one side, and a single speed on a freewheel on the other side
they do this so that you can switch the wheel around to choose between riding fixed and being able to coast
>new to cycling, don't know much about framesyou're looking for a commuter, and you're probably not looking to go super fast, so you probably want a frame made out of cro-moly, which is a high grade steel. it'll be heavy(-ish) but indestructable and cheap, and you wouldn't get much out of aluminum/carbon fibre if you're a new rider
you want something that's rigid, as lower end suspension is beyond shitty and can be dangerous at times. also, there's no need for suspension if you're not going on rough trails
as for handlebars, drops can be comfy if set up right, flat bars are really comfy, but don't look as classy and aren't aero
>is it any goodnot really, but as a cheap beater it will work. its expensive for what it is, and personally i hate that sort of thing (and 90% of fixies), but some people love them
you can get much more bike for less if you buy used
another thing to note is that if you buy online, you'll have to build it yourself. it really isn't very hard and its a good way to learn, but if you just want something you can grab and go riding, then that might not be what you want to do
>being able to coastjust my personal opinion, but the main reason not to use a derailer is because some people really like the feel of riding fixed gear. i don't really see the appeal, but some people swear by it. there isn't really much reason to ride with only a single speed with a freewheel, cause having gears is really nice
