I leave mine on max all the time, I keep hearing it's more efficient to turn it off for cruising but you can just hold the throttle neutral and if that's annoying to you then just give your handlebars the reacharound so you can cruisecontrol it. I just don't understand what scenario you would possibly want *less* regen.
Tbh, I want a clutch, so I can do clutch wheelies and other fun activities. J/k
But seriously, having to reach over for cruise control sucks, rewiring it is a good second. I do want to treat it like a clutch and be able to let go of my right hand quickly without slowing down, reaching over for cc, or going into settings.
A regen lever also adds more regen granularity without having to sacrifice throttle granularity. Plus its not unintuitive, and is really not complicated.
I'll probably put a rear brake on my left handlebar for fun though.
