Anyone made an electric Doran?
After I get my a** in gear and finish my truck, I want to build a small
low-profile 3-wheeled electric...

The BugEV is a little too light-weight, though I thought about it... and
the Doran seems too big, and I don't know anything about fiberglass.

If the BugEV were heavier....

Suggestions?

I'm waiting on the XR-3, but that from the pictures I've seen, RQR hasn't
finished the design yet (major structural change from earlier pictures
I've seen)...

Moreover, it looks like with a diesel engine + lithium batteries - that
it's going to be an expensive undertaking.

Is there anything out there thats electric, around $5k, 3-wheeled-tadpole
design?

Used Sparrows requiring refurbishment, perhaps?

Thanks, Best Regards....

[EVDL] Gizmo Gearing






I had a a couple Gizmos. One was quite early and the other was fairly
recent. They both were geared at about 6:1.
They both seemed to have the right balance for starting and running
at top speed (~40mph).

Ed,

Of the two Doran's made BY Doran, one of them was a full electric,
although the motive design was pretty primitive. The other one is in
the EVAlbum, and was probably converted later:

Stephen Taylor is a collector it seems. :) If he is around I'm sure
he'll be happy to pipe up.

Anyhoo, as you can see the range is pretty low, mainly because there
is very little room to install battery, and the weight allowance is
pretty small for the Doran constructed per plans.

I'm sure you could adapt the design, and put more battery in (AC
Propulsion put in enough lead in the TZero to make it go pretty darned
far) but of course, that would increase the cost.

OR you could put in Lithium and get something like a 5 times range
boost (increased DOD and 1/4 the weight). Maybe more.

But then, that's not $5k

Ed,

Check out these electric Dorans on evalbum.com:

http://www.austinev.org/evalbum/559
http://www.austinev.org/evalbum/243

You might look into the Vortex (another hand-built 3-wheeler), although
I didn't see any on the album. There is an active Vortex group on Yahoo:
