I recently upgraded the transmission on my not-a-bike (Street Strider) from 3-speed to 8-speed, using a whole rear wheel I bought from Terra Trike. I didn't want the twist-grip shifter, so bought one off Amazon, but it's not listed as being compatible with that hub. It's an Alfine shifter, and I have the Nexus Inter-8 hub. However, reviewers on Amazon said they had paired it up with the Inter-8 and it worked fine--and it does.
