Put some Mary bars on a 10 speed type bike,PRESTO,fast upright bike.



Same bike,same motor,sit upright.......


I changed the bars on a couple of my friends older type 10-12 speeds(1980's) bikes and both of them are happy.They cruise around town and ride to the beach and back(35 miles).I even put a big cushy seat on one of them,that's what he wanted,he doesn't complain about it.They look like old Schwinn Collegiates,fenders and all.
