Mike,
The Easy Racers chain tensioner could be used in conjunction with a
jackshaft for a step-up gear. Be aware that the jackshaft will see large
loads so the connection to the frame needs to be substantial.
Due to the relatively thick walls and frame material (1018 Steel IIRC)
of the EZ-1, any competent welder would be able to attach a jackshaft
mounting. However, the easier way to obtain wide range gearing would be
to add a SRAM DualDrive hub (this would work with the existing rear
derailleur and cassette.
You should realize the danger of hanging out with Ben Fox. Ben has an
advanced case of recumbitis [1] that is contagious. I believe he caught
it from a bike he purchased from an alt.rec.bicycles.recumbent regular
who suffers from the same disease.
[1] A disease that leads to the constant purchasing and selling of
recumbents in the elusive search for perfection.
