Hello,

I have controller (KZQW22A-LKTS17066-HJC) in my ebike with rear hub motor.

Can I remove speed limit somehow?

Or can I change current LED display with throttle to LCD display which would allow access to settings?

Blue wire had to be connected to allow 25km/hour with throttle (otherwise 6km/hour).

Some pics attached.

I've not seen one of those controllers before, but it doesn't look easy to adjust. If you can't find out how to hack it, a replacement controller with LCd would work, but you'd have to change some wires and replace the throttle with a normal one.

Thanks for the answer. What do you mean changing wires?

Any ideas how to find suitable lcd controller?
Pretty sure he means connectors . There is no real standard with these Chinese controllers so , for example, the Lcd connector on this may be different from any replacement

You either need to solder direct or replace the connectors

I think, if D8veh can cos it’s beyond me, to manage some expectations a bit. Which needs knowledge and calculations I cannot do

Although a new controller will help ; the whole system is also limited by wheel size, motor windings and battery capability

I’m only trying to avoid you spending time and money to gain 1mph :) !

Change connectors and/or swap around the sequence of wires in their connector.

This is a nice controllerif your motor has hall sensors. uou need to count the conductors in the motor wire to dertermine that. eight or more is sensored, 6 or fewer is sensorless:

It has a different motor connector, so easiest would be to cut your connector off and join the wires directly.

Hi, joined yesterday and can't workout how to post?

As ob the subject of speed restriction. I have ordered a Speed box 2 for my new cube ebike. The device is turned on and off via the walk button. I just wondered if anyone knows if the walk button function of actual walk assist will still work?

Anyone used the ebike tuning company in Germany? They seem to have a good reputation?
