Ladies bikes

hi, I'm new to this, but also looking for a cheap decent frame, I'm 5.4 living in London, 19 yr old student so would love to have something set up before I return to uni. thanks.

A few questions:

1) what's your budget?
2) Do you want to self build,or get a complete bike

I would guess you would need something like a 50-52cm frame (someone please correct me)

Depending on your answers your best bet is to do the following:

1) Trawl the classifieds here and check out ebay (be very careful about gumtree, a lot of stolen bikes are sold there)
2) If you want to build it yourself read http://sheldonbrown.com/fixed/index.html

If time is a constraint then you may want to get a complete - this will prob cost you more but you'll have something quicker.
Building your own is a lot more fun and you'll learn a lot as well, there is plenty of advice resource on here - if you have the time. It will also cost you a lot less.

Good luck
