Been reading up on e-bikes for an upcoming company move with a new 15 mile commute that I may have to do for awhile. I luckily found a 2013 Ohm Urban XU700 locally for $1750. Not sold on the it's looks, but for a 350W Bionx equipped e-bike with everything needed for commuting for $1750 before tax I can live with it. It comes in two sizes 18.5" & 20". I did a short 15-20min test ride on each & the 20" felt more comfortable with reach but I might have had to slide a little forward on the seat. The 18.5 felt a uncomfortable at the handlebars, but it may have been me not use to the slightly more swept back handlebar style & it might not have been set up optimally but was the bike I test rode first. Just curious would anyone here go for the 20" at 5'7" 30" inseam? My arm span is maybe 2" longer then height.
