I didn't buy one rick but I'm going to..we had the parts bent up out west at a bike fabricator.
One bikes getting simplex so it should be a pig...the other either a gc190 or a whizzer engine with electric start... That's because I don't wanna try and do a kick start on the whizzer.
One thing I don't like is the simplex stand for mounting the rear wheels...may salter the look and shape of those. I tried a set from 3\16 and they're just too funky for me.
It may be their height(with the back of the bike at 7 13\16 which DW gave me for a height there).
I have a third frame and may space the two front bars apart more...moving it closer to the seat to increase the height on the top bar...that would help.
For now,these two are going together as is.
