Realizing that it's not an ideal scenario.........I did snug the pedal threads, set the chain tension with the rotation of the elliptical in mind. I did orient the chainring the same as it would be on the normal drive side. Conditions on the fixed cog and lock ring are probably not ideal either. It does have a little slop in the drive train. Cartridge BB should not be an issue. I can assure you, it will not be ridden very aggressively by me. We have a quarter mile paved loop at our Quarantine Compound for test rides and such experimentation.
