e-Assist?

Has anyone successfully added e-Assist motor and battery to an S40?
I'm 100% psyched for an S40, but based on my current age (75), I need to have e-Assist going forward
(I've been riding a Bacchetta Corsa recumbent for last 15 years)

I have successfully attached and used a Bimotal system, but only with a McGuyver attachment that is not ready for prime time. Possibly in a bit an official bracket that makes this a viable solution is in the works but no ETA at the moment from Bimotal.

Someone I believe attached the Skarper system, but that Is not sold in the US unless they have received their certification to do so - which I heard they were working on but that was just a rumor.

The above makes for an AWD bike with is an awesome experience for sure.

Thanks Robert,
Fingers are crossed that the Bimotal system is viable and might be available in the next year+
