I found a couple fasinating front wheel drive recumbent trkes, but the computer shut down before I could save info.
now impossable to find agian.
found utility trikes of same, but too large they be!!!
and why cant these people put vidios on thier sites?

The popular delta trikes are like the Sun EZ, Hase, Lightfoot and
Penninger (probably in this order).
SWB like the Stites and JTB Raven are low production thus far. I've
never seen or ridden either. I did ride the original Raven several
years ago.

The Raven's drivetrain should work fine. More of a concern, based on my
past experiences with lean/steer type deltas is high speed stability
and steerability.
By this I mean that this type of steering needs more stability at speed
and an increased ability to turn sharp at low speed. Another trike
built years ago in BC Canada, had rear wheel steering and FWD. It had a
variable/adjustable steering linkage depending on whether you needed
better high speed or low speed steering ability.

March. You might be able to see it at the show.

The main problem is getting a long chain. These days most are spliced
together using quick links. Sometimes mfrs buy chains by the roll,
which is a better idea. Long chains wear better and don't have as much
trouble with deflection angle that plagues 9/27 speed drivetrains.
They take longer to clean and cost more to replace. More of a concern
is the quality of the idler system. We call this chain management. Some
are horrible, and some work great and are nearly silent. I think some
2-chain systems are problematic. I'd prefer 1 chain unless I'm getting
something for the added complexity and weight of the two chain system,
such as a wider gear range (Lightfoot does this). Some are unnecessary,
especially on commuter type recumbents (what we call compacts or
compact long wheelbase).

I don't know of any volume production models that have FWD.
The new Stites Design trike has FWD (upcoming RCN 082), but it hasn't
really been in production yet.
Often you don't find new and unusual drivetrains on recumbents because
it could be considered too much new technology. Most builders want to
make as few explanations as possible. For the Stites and JTB, FWD makes
sense.
