Sun Easy Sport AX here. It's pretty much my transportation here in town.

I got it to relieve the pressure on my hands - and to ride across the country. It's kind of a slug on hills, but any bike under my mass, especially with all the Stuff for a commute or a tour is a slug on hills. I just enjoy the downhills more than most. (Brakes? On a downhill? I think not! )

This winter I've been commuting on my daughter's MTB. As soon as the ice is off my route, I'm going back to comfort - and 27 mph downhills.
