thanks ill surely look into a qualisports for my wife.im 150lbs so the 3kwatts kit will give me plenty of torq and speed provided my bike can handle it, therefore would like a complete new rear wheel setup for something with wider tires/rim combo, plus that white industry freewheel cog. i hope to just continue to use my fixie type frame and not need to go the purchasing of a mountain bike. i plan to just use it to cruise around for fun. the metro in california allows full size bikes still.
