20mph? I barely get 10 miles per hour.
Under what riding conditions? Flat smooth roads, or hills, or sand, dirt, rocks, etc? Winds? (and so on...)
Does the battery meter show any cahnge during acceleration vs riding slowly and steadily vs riding faster and steadily vs just sitting there stopped?
Does the battery itself get warm during operation?
Note that some localities have legal limits on the speed of ebikes; some very low. If the kit you bought was made to be sold in such an area (even if yours is not), it may have a built-in limiter preventing operation beyond that speed. The ad for the kit doesn't specify what speed it is able or intended to go.
Yes, there is a 3-speed switch.
What change, if any, is there between the 3 positions of that switch?
Were these steps (from the linked purchase website) performed after the system was installed on the bike? If not, the motor may be being driven incorrectly by the controller.
1. Turn off the power supply and the switch lock.
2. Connect the Hall wire, motor phase wire, switch lock wire, throttle handle wire,identification wire, and power wire in order to start debugging.
3.Turn on the switch and the motor starts to rotate. If the wheel rotates in a forward direction, the debugging is successful; if the wheel rotates in a reverse direction, unplug the identification wire and connect it again until it turns in the forward direction and the debugging is successful.
4. After the debugging is successful, separate the two identification wire, turn the knob to confirm the success, turn off the switch, and connect other wires as needed. (When the motor is rotating forward, separate the identification wire without turning off the power supply, the motor will stop rotating, and the motor will be fully controlled by the handle at this time. Turn off the power supply and the commissioning is completed.)
It's a front hub 500w version that did not have an LCD display included. My question is how would I connect such a display as I wish to try and change some of the controller settings. Looking at the photo provided can anyone tell me how I could connect an LCD display?
As noted by others, that controller probably doesnt' support an LCD.

I have been looking at KT products. Could you suggest parameters for the controller? I have a 500w front hub motor, twist throttle, 52 v 10ah battery. No pas sensor. Does the controller have to say it's suited for a 500w motor etc?
The reason for all this is I am barely going15 km per hour and uphill, turtles pass me.
You'd need to list the specific conditions you ride under, worst case, and what you need the bike to do for you, specifically, for us to suggest parts that can do these things for you.
For hills, total system and rider and cargo/etc weight also matters.
Hills take more power than flat roads, the steeper the hill the more power, and even more the more weight there is to move up the hill. Same thing with speed; faster takes more power because of air resistance primarily (which is why fighting winds take more power, too, it's just like riding that much faster--10mph headwind plus trying to go 20mph means taking as much as twice the power just as if you were trying to go 30mph).
