This is an electric trike (three wheels) that uses a hub motor in each wheel to propel it. It is a 36volt system, using brushed motors and a single controler. It is a prototype by Howard Letovsky, the president of Letovsky Dynamics. further report at: http://cyclesantamonica.blogspot.com
This was one of the many unusual vehicles that attendees to the AltCar Expo brought to the expo informally, and were showing to people and allowing people to test ride.

with 3 hub motors u could use that to pull tree stumps hahaha.i put a electric motor on my bike because i heard it was illegal to pedal azz.well im a little disabled to so it allowed me to ride with normal people.have fun
They have been putting generators on bikes for years to run a lamp. hook a generator up same principle to your drive.. will get you farther even at a 50% increase in charge or what about 25%???? chose people all they talk about is power power power. how has that been working so far??? Think outside the box...... new ideas create new inventions...
Ill always argue. I've Been mad about this for 30 years.you still years behind,,where is the self charging system?? not to mention the 4 wheeled motored system?? I dont see the power gearbox yet anywhere.The motor is not the key its the power gearbox.So get to work ,make the power gearbox, change the way the world travels.And remember im watching..
(disclaimer: I have all kinds of concepts but no money or time so all i have is theory talk, so pardon my ignorance but i'm trying to learn as fast as possible.) 1. Doesn't a gearbox defeat the purpose of a hub motor? What about capacitors? 2. I prefer fewer parts for lower maintenance cost. So i gravitate toward designs with hubs only, or dual CVT's or large capacitors for acceleration. 3. Gears add weight, noise, and maintenance costs, right? 4. Can motors have torqe/current controllers?
1 a hub motor is direct drive. as opposed to gear drive which can take x power from the power source and mutiply it to the drive hence less power more drive.. pedel a 21 speed bike as you change gears same power more drive ,or less as you chose.. put a power hub on a bike as the drive gear on a 21 speed bike instead of direct see what u get.. get a 1 ton truck to go 100 miles on a charge and you solve 99.9999 percent of the proplem. the need for fuel.......
Electric motors have a very flat speed / torque curve which negate the need for multiple ratios. Humans and petrol based engines don't have the luxury of such a flat speed / torque curve, hence the need for gearing.
Regarding regen systems, they are already commercially available for powered bicycles, and have been used in industrial electric drive applications for some time.
Quite frankly, were all thinking in the same box - some of us just don't realize were in it.
No pedals on this one. The designer, I think, was making it more for people with mobility issues, and for people to have whom may not have capacity for driving a car because of thier age.

pedel a 21 speed bike as you change gears

put a power hub on a bike as the drive gear on a 21 speed bike instead of direct see what u get..
