Simple Electronic Clutch Modification
The Electronic Clutch EM came up with for the ePure bikes is shown below. It is part number TC01L-60403-00-00-ASM. Unfortunately, it costs $423 and is not compatible with the EM 5.7 system.
I did not want to butcher the factory wiring harness, so my addition simply plugs in. It goes between the power mode switch box and the main wiring harness. The clutch switch also plugs into it.
It went a long way toward making the bike more intuitive to ride. Several people told me they were better off removing the Oh-Shit! switch entirely and ride with just the throttle. I believe them, but this is even better. Of course, it still does not provide a range of modulation. For that, you need some sort of progressive electronic control (like the throttle, but for the clutch lever).
I had an idea of how to build something that will work even better. It is described in the Progressive Clutch section.
