ah yes, the used market is a much valued resource and I would highly recommend craigslist.com. I bought, sold and then bought another folder on in Toronto. The ralligh 20 is an older bike, but heavy. For $150 there is a folder at walmart that has speeds and is possibly lighter and NEW. I would take a long look at the ones there. I just took a ride on the $100 walmart special that has 12" wheels! Folds really compact, rides decent and is around 20 lbs to boot. Finding replacement tires would be a challenge and really, there is no speed to be had from such a small bike, so 16" and up, but walmart in Canada does not have much.
