I looked at bunches of pics of long wheelbase recumbents. They all have about the same geometry. I'll try out a fork and put a 24" wheel on to see how high the BB is. I think most use a 20" front wheel with a larger rear wheel. And a lot of chain.Took a few to realize it's a recumbent. The BB looks low though?
I had a Bike E several years ago but it always felt twitchy and balancing was always difficult even though the seat was great. I couldn't turn to look for traffic either.
