Rahtmobile
 
The maybe should be in a different forum but I'm used to this one so here goes..... this is an Elio but lighter, smaller , a trike with BIG electric assist and really good aerodynamics .

Looks pretty cool!

Here are a few pics since their website isn't the most... robust and informative.

The kickstarter page says "Funding for this project was canceled by the project creator on April 23." It had raised about $30K of $75K. I wonder why they cancelled the campaign?

I'm not so much into pedalling, but the design looks promising for a small electric with 3 hub-motors.

PeterS 07-31-2015 12:41 AM

I think it's basically a light EV and the pedalling is to allow it's non registration as a motor vehicle.

I like the cabin, very neat indeed !

I may be off a bit, but it seemed to be a gimmick to pedal the thing and have it hit 70 mph by pedal power alone... even though it was just on a test stand and not under much of a load. "Power amplifier" reeked of snake oil to me... maybe just a bad use of words for marketing. Maybe partially true, but possibly misleading enthusiasm. Meh, maybe. He only had to make the rear wheel spin but not actually make it move through the resistance of air, rolling resistance of the tires and carrying the weight of the vehicle and rider.

Carbon fiber looks neat, but it heats up mighty quick in the sun and there didn't seem to be a lot of ventilation there for cooling the rider... for streamlining purposes I'd think.

Registered as a motorcycle due to speed and possibly electric motor HP. But with that comes the problem that Elio has been lobbying for a legal solution to regarding helmets. These may have been hurdles that they didn't have the wherewithal to overcome at the time.

And really, how many people (even if you include the niche group of bicycle riders) would want to pedal their guts out like that? The presumed fix for the more lazy of us; a markedly larger group, would be to add more batteries. But that means more weight. At some point there are going to be diminishing returns on the extra weight and probably a lack of space for said batteries.

Finally, I never heard nor saw any mention of cost to get one. Which may have been a deal killer. And the clean energy challenge page was not clear on winners, but apparently Raht racer didn't make the cut. Without backing, maybe they just gave up.

Who knows?, maybe it's down but not out.

I think this guy got funding from an investor on a TV show, like Shark Tank or something.

With the stated MSRP of $35,000 that is just not going to sell.
With what looks like bicycle tires and wheels, no way it can go on the freeway.

It makes the $9,500 price on Nimble Motorsports The Indy One Electric Kit Car look like the bargain it is.

PeterS 07-31-2015 03:10 AM

Yep, silly expensive !


Top speed of approximately 100 MPH / 160 KM/Hr.
Range of approximately 50 miles / 80 kilometers.
Regenerative disc brakes at all three wheels.
Electric engine power rated at 26.8 HP / 20KW.
Li-on battery, rated at 9.2KWH.
Two seats, only the front seating position provides pedal power.
Curb weight of 570lbs / 258.5kgs.
Expected MSRP between US $35,000US and US $45,000.

With those aerodynamics and such low weight, 100MPH seem achievable. But I wouldn't feel so confident to try it with those skinny tyres.
