In the seated position it rides a little squirly because of the handlebars and also because I deraked the fork angle just a tad. This makes it handle like a dream as a stand-up. It really carves

update 10/ 09 the bike has been through a set of tires,and still works great,this one's a keeper

update 10/26 motor and controler went out in a blaze of glory,am rewinding the motor,and bought a new controller,lb37 48v,50 amp

update. the motor rewind is a success,and with the new controller,i think it is running close to 30 mph.i will clock it after break in

the battery wires,and controller were getting hot,so i replaced the flimsy 14 guage wire with 10 guage and used gold plated spade connectors.the wires and cotroller seem much happier now. the bike now clocks in at 35mph

update 2-10-10 i finaly got sick of replacing the band brake every time it broke,so i upgraded to disk brakes front and rear.it stops on a dime

i finally fried the rewind,and after some mods to the frame i replaced it with an ultramotor brushless hub from an a2b bicycle.i gutted the controller and ron a lyen 12 fet infineon externally
