If you want to have multiple gears with a shiftkit but stay legal this could be the set up for you. Mr. Kilduff will also sell the shifter by itself as well. He said you can adjust what speed you want the gears to change at. There is a beauty cover for it as well. This is his number 818-789-9293

The one posted now worked for me. That's pretty slick. How much does he want for the shifter?

Thanks for sharing,

Got it right now. I was told $80 for just the shifter.

I like his idea - simple. However, how about using a vacuum actuator rod with a vacuum port on the HT/China Girl intake as your source of vacuum.

Another brilliant guy in our midst.
Looks like he is using an automatic transmission governor to do the twirling and pulling.
His brake idea is great- using the pull on the coaster brake lever (that is free but limited) to pull the V brake.
Only issue I see is the rear rim must be kept true for the little wheel to ride on constantly.
Really, I am impressed.

In the near future I'd like to build another autoshift bike. My 5 speed LandRider works great. For my next build I want to use this system on a cruiser bike.

LR, or anyone. Do we have any history with shifting these IGH's under constant electric or gas engine power? Even with an autoshift our pedaling cadence provides natural low torque periods for shifting.
