Controller with instant throttle response?

[electric_nz]

Coming from a motorcycle background where throttles are instant, I’ve been a bit disappointed in ebike controllers so far.

Often the throttle response has massive lag; doesnt seem to be proportional at all to the input; and some of the soft start/slow ramp “features” can be dire: one I tried even had a slow ramp down as well which was downright dangerous— it literally kept accelerating after you had closed the throttle!

Are there any reliably good models of controller with a snappy throttle response? Ideally around 72V 40A kind of spec.Don’t really need a display, Bluetooth or any features; just something that is quick to ramp up and down- like a motorcycle.

Hard hitting controllers at the Voltages you are talking about make an ebike hard to ride.
Any of the older square-wave Infineons are hard-hitters.
Or contact Lynn (lynn.com). He can customize a controller into anything you want.
