surron feels kind of herky-jerky

Question

if you try for a steady cruise at half throttle, the controller feels over-senstitive, and the bike feels very herky-jerky. you're really careful with the throttle, you can get it to settle down, kind of, but even then it lurches and so on

does anyone else have this issue? how do I know which controller software revision I have?

thanks

This is almost definitely due to the way that regenerative braking works.

When you let off the throttle, the bike is applying an inverted torque on the wheel to reduce speed and generate electricity to charge the battery. This can cause the bike to feel extremely jerky when you re-apply throttle or when you let off.

This is inherent to the way the bike is programmed, however you can always disable or lessen regen with your programming cable and brake cut-out sensors. This is something I plan on making a video about, but until then, here is a great link to change this yourself!

@bruce.t.buchanan you will still have some level of rolling resistance, but highly reduced.

hey thanks for checking in on this! I have changed the regen setting to "off" but there's still plenty of engine resistance when I let off the throttle, enough so that it still feels pretty jerky...

with regen off should I feel no engine resistance? some but less? I'll double check to see that I disabled the regen properly!

Would getting an after market controller fix this? Custom settings via apps?

why would the old cable throttle be any less glitchy?
