I see what you were trying to do,which would have some value to perhaps new people.But there are way to many variables,and folks get too defensive,then all your trying to do gets forgotten. I like the idea that you can get different sizes in Tikit for instance,i like the idea of different handle bars like Brompton.S-type which arent only lower but further ahead.As far as gears go i would want s/s in either so im biased that way.Actually car manufacturers are good at producing so many models one cant really compare without confusion.I guess there just trying to fit different bums to different seats so to speak lol.And if confusion in comparing, as a side to it happens, im sure there happy with that too.Cheers.
