I never got this constantly repeated refrain of "Save up to buy a better first bike" to new riders with limited means from some of the more vocal members here...

A new, inexperienced rider can't tell if what they are riding on is a slightly better, or worse bike - why should they spend more money on something they may not even get into and that will end up sitting unused in a corner? If they do happen to catch the bicycling bug - they have plenty of time to blow their money on higher end/better equipment later. I know (and occasionally ride with) lots of people in my area who are riding crappy Pure Fix/Critical Cycles type bikes quite happily, in some cases for quite a few years. My own kid started out on a cheap bike. When he stuck with it - we built him a nicer one.

OP - buy whatever you can afford and get to riding now. Hope you enjoy it and stick with it, and then spend your life "upgrading" your bike ****...
