I've ridden an electric. Very smooth & quiet. Performance in the 14-15 mph range. Owner said this 36 volt unit was good for 20-25 minutes on full charge. SLA's are heavy and bulky. At least w/ the Worksman you are supporting an American co. and that, IMO, matters more now than ever. Have to admit that I'm very fond of the Husky HD-105 as a friction drive donor. The alloy wheels use apprx. 12 ga. spokes and have flat vertical rim sides which work nicely w/ v brakes and a mtb shock fork. Toss up right now since I enjoy both bikes much. Believe it or not I can get a better quantity deal on the Worksman! Wayne Sissum at Worksman told me they sell so many bikes to mb'ers they're toying w/ the idea of developing a unit specifically for mb use.
