my apologies if this should've been posted in an exsisting thread, but i was interested in purchasing this bike if it was still available. folding bikes have intrigued me, but i have vurtually zero knowedge about this segment of bikes. could any of you give me any info on this bike such as wheel size, buy or not buy, etc.

thanks.
