Hi i recently upgraded from 36v to 58v and put a bigger bat on my bike.
it used to go 16-17 mph on lowest setting 36v and legal enough.
i dont wanna be risking an encouter with the law that goes beyond a quick ok goodbye.

im using a cheap ebay scooter or ebike brushless controller 350w and got no cycle comp other then a speedo to change anything.
it has 3 speed settings, basically left 80% and right 100% then turned off centre gives you 95%, really lame... the bike is now doing around 23 and 28+ and 27 when off.

my question is how can i limit it, my heads telling me i should be able to replace something in the controller to drop those settings to a lower % but no clue what that is so would love a point in right direction or any other ways to do it thanks.
