hi,JOHN LUSSMYER ev folks A Sparrows seems to me a very attractive EV vehicle for commuting and the yellow tops a good choice.BUT
-1.USA seems not have understood the energy problem they are facing. Even with the hugest quantity of coal-reserves for the elecricity plants people will be faced with higher energy prices. Their cars and their EV are way overpowered.Burning tires is fun but outdated. In germany,switserland ,austria ,scandinavia EV people are focusing far less on horsepower but on small commuter single person transport vehicles with far less power but up to 60 , 70 km with 45 km/h speed. they do this with 3 to 4 pb batteries or with high tension expensive batteries I will try to give a descripion later . http://www.cityel.com/ http://www.bineco.dk/ellert/lynch/index.htm http://www.lynchmotor.com/ -2 USA seems stuck with high torque series drive too strong acceleration and too strong regeneration at low speeds read this on torque and regeneration with belts: http://www.4qd.co.uk/faq/bmnc4.html#spstab solutions: if you can get to work without highways - use a smaller engine/shunt or permanent magnet (original design 8 hp) - (automatic ) limitation power to 80amp maximum http://www.hotzenblitz-service.de/I-Matik.htm - put smaller wheels on the sparrow as in the original design (less drag) - drive slower / you overturned already once . Personally I find the european el city and twike too small. http://www.city-el.de/c82.html The new designed SAM has two places and that is already better. http://www.ch-forschung.ch/fs/0110/S2-1_sam.htm and last but not least these pages: http://www.testsam.ch/frame.php?lng=en&cont=vis greetings
