I was just saying a x10 would be a cool choice .....

A Dahon Vector P8 is a bargain right now..... add a jetstream short one piede handlebar stem ( if you dare ) to make it much lower in the front and much stiffer.... maybe wait until I have some ultrafast 20 inch wheels available ... add a 2nd chainring .... and you would have a hydroformed frame for a low entry level price ... than start modding with change to spare ...
