i rode the A bike..
just alittle bit better than walking..
you have to watch for every crack,bump,etc..
or you'll be sorry..
also not suited for a tall person...
with all the joints in the frames..very loose ..
it feels like you are trying to balance yourself all the time..
so if you really want all the short comings of the A bike..
then go for it..
just my 2 cents..
