Vancouver. 5'3". Used to ride a26" wheel but not sure of frame size. Tux for ur reply.
My two favorite full size bikes for shorter riders are the Easy Motion Evo Eco Lite (Sold out for another month or so) and the
Pedego 24" Interceptor II (Step Thru Frame with 24" wheels specifically made for shorter riders). On the higher end the
Felt SPORTe will be available in a small step thru size this month, but I'm not sure there plans for distribution into Canada. Depending on your time frame there may be some more bikes released this fall after
Interbike (the largest bike show in NA).
As Vandor mentioned the other consideration would be a bike with 20" wheels, there are several out there including bikes from Easy Motion, Currie and Ejoe. I also agree with Calvin, its generally better to invest a bit more to get better quality and pay close attention to the manufacturers history, if they don't have much be careful, they could go out of business and you're stuck with an bike you can't get parts for. Also look at the warranty and if possible user reviews.
This site is a great resource with some very knowledgeable members, if you spend some time browsing around you can learn a lot and it will help you make a wise investment that fits your needs.
It seems like there are a good amount of dealers in your area, from a brief Google search it looks like a lot of them sell junk though. Do you research and make sure you buy from a reputable company that you feel comfortable with. I don't want to tell you what to do, I just want people to be happy with there purchase and the bike to give last, there are too many crumby bikes out there that have been hurting this industry.
I hope the above info helps.
