Too bad this seems to com in only a 26 inch wheel format: https://www.geoo.com/
"The Patent Pending GeoOrbital wheel is an evolution of the orbital wheel (the wheels on the TRON Motorcycles). The GeoOrbital wheel replaces a standard bicycle front wheel to turn your bike into a powerful electric bike in under 60 seconds. The only part that is attached separately from the wheel is a simple thumb activated throttle, which is easily clipped onto your handlebar. The Panasonic 36V removable Lithium-Ion battery (with a built in USB outlet for charging your electronics) provides a pedal assisted range of up to 50 miles per-battery (up to a 30 mile range for the 26 inch wheel). With little to no pedaling you will go up to 20 miles on a single battery (up to 12 miles for the 26 inch wheel). The more you choose to pedal the more range you can expect, and you can always take a spare battery with you for longer rides. The GeoOrbital wheel comes with a flat-proof solid foam tire, so you never have to worry about getting a flat or even checking tire pressure. By using the latest hi-density foam technology the tires act and weigh the same as a traditional bike tire, but you will never get a flat. Never!" -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Most-efficient-drive-system-for-a-bicycle-tricycle-tp4686908p4686947.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
