“My light-bulb moment was, ‘What if the pedals are not connected to the drive train?’ ” said Kron­feld, who conceived of an electric vehicle with pedals that only generate electricity.

It's created and made in NORTH America, by Americans, for American driving habits. Not Swedish necessarily. Definitely made for Speed limit 65+mph. I wish them much luck. Americans need small vehicles.
 
this is really cool! if they end up making a production version and selling it for $12,500 that seems like it would be a pretty fair deal - especially for the components included when you compare it to something like the Stealth Bomber which is close to $10,000. It looks like an Enertrac hub motor - quite a bit more powerful than the stealth's crystaltes - lol :lol:. plus it has 6kwh lipo and a completely enclosed aerodynamic body! it would definitely be more comfortable and efficient. although its not a replacement for an e bike (they obviously have other advantages) this is still really cool...hopefully it makes it to production at the price they state =)
 
Does 600#'s strike anybody else as heavy? I bet the Zero trike will come in closer to 450# tops.
 
600 pounds plus rider being pushed by one of those "tin pot" hubmotors = heat problems and/or poor performance. Slick velo though, and it even has what I call and "electronic chain".
 
The Human Electric Vehicle is a three-wheeled, energy-efficient vehicle that is part car, part motorcycle and part kayak bike. It combines the pedal power of a bicycle with an electric engine and features a tablet computer that gives information on mileage and speed. Minnesota-based designer Lyon Smith and CEO Rich Kronfeld hope to perfect the vehicle and enable it to travel at the speed of up to 100 mph, with a range of between 50 and 75 miles per charge.

Weighing about 700 pounds, the vehicle is street legal and is considered a motorcycle. Its carbon fiber chassis looks like a kayak, and is reinforced with structural foam, similar to an airplane. The exterior was constructed in collaboration with Winona Boiler and Steel, as well as We-no-nah Canoe and Cytec Engineering, who donated the carbon fiber.

The vehicle uses a regenerative brake system, which feeds the electricity back into the batteries when the brakes are applied. It also has a solar panel mounted on the roof.

4.5KWh battery, 50KW drive motor and a pedal-powered generator? Why?!

Extra weight & complexity for ~100W of power? That'll be fun when you're cooking under the blazing sun in a little greenhouse on wheels. Unless it's instead of a heater, for use in the winter?!
 
Pushing the envelope for motorcycle license.
Brilliant design.
It is heavy, due to the complex aluminum frame.
Too bad they just didn't fabricate a carbon fiber belly pan and monocoque chassis.
This would have minimized the aluminum frame.
They could replace the shocks with shock rods and inboard shocks.
This would be much more aerodynamic and lighten the unsprung weight.
 
This looks to me like a good step in the right direction.

Generally speaking, properly engineered metal parts have a better durability history than carbon composite.

Simple shocks are more initially economical than more complicated systems.

You pays your money and you takes your choice. Initial economy and durability or greater cost and higher performance.
 
I think the price tag is very high, but this is getting really close to my ideal commuter vehicle.

If they can bring them to market for under $10k, they might sell a few. Super cool idea though.
