Recumbent - Recumbent for adaptive cycling

My wife has MS and is not in great physical shape. I run and ride quite a lot. I'm looking for something that can help her get more active and hopefully that we could do together. Is there a recumbent solution? Perhaps a trike that would have enhanced stability? Is there a tandem arrangement for bikers of unequal strength?

Thanks for any help here.

Look at the threads "Biking without arms". The suggestions could apply here too.

Basically:

– A handcycle would work for her if she has good arm strength. But even with powerful arms, hills remain a challenge.

– A traditional tandem works great for bikers of unequal strength. As long as she is stable and can spin the legs (or let you spin them), she is OK. By "stability", I mean that she needs to be able to stay upright; no need to keep the bike upright, because that's your job. If she has still legs, she might need something like the DaVinci Independent Coasting System.

– A tandem tricycle such as the Greenspeed will work even if she needs time to sit on the bike.

Thanks Michael. I'll do the research on these options.
