Hello guy please can anyone help me with finding a controller and display for my bike 48v 250w maximum 22a fat bike.im looking for a controller and display so I can change the pedal assist percentage.ie,0-5 so 1 =35% 2=45% 3=60% and so ,can anyone point me to the correct control and display.

Hi not sure what you mean ? Matching pair

48V times 22A is about 1050 watts. That would qualify as a nominally "500W" bike in today's very permissive regulatory environment, but I don't think anyone would call it "250W maximum" with a straight face.
KT controllers and some of their displays allow you to choose the percentage of maximum power for level 1, but 5 is full blast and the others are evenly distributed in between.

This my controller bike and hub motor,I'm looking for a different controler and display where I can change the pedal assist percentage.much appreciate your help

You can gamble buying them separately, if you like troubleshooting go ahead.

You don’t want that, it’s only a 36 volt, 7 amp controller. Check out the 48 volt sensored KT controllers and KT displays from top bike kit. If your battery is big enough then you can upgrade to a higher current controller.
You must use a controller that is slightly lower than the maximum current that your battery can provide.

Wow thanks this complicated not sure which one it is I opened the link but I'm not sure.its all a little more than I thought,so no idea which controller is the right one but I need also with display.
Thanks for the speedy response much appreciated.

You need to find out what the maximum current that your battery can deliver first before choosing your controller.
If your controller is too big for the battery then you will damage your battery.
The controller that came with your bike is 22 amps, so you know that’s safe. But if your battery can deliver over 30 amps, then you can upgrade to a bigger controller.

Hi chalo could you send me a link to the correct control and display for my bike

Most controllers do not allow individual tuning of each PAS level. That's preset for the level they provide. Some might allow you to detune the entire controller (KT does that), so you can slow down all of the levels. There really is no point in having ability to set levels beyond what the manufacturer originally intended. Just switch your PAS level up/down.
The only controller I know that allows PAS levels to be set is the Bafang controllers in their mid drive units. All you set there though is the speed limit for each level.

Hi sir thank you for that I'm trying to increase the %level in 1 an 2 there are extremely sluggish may I say ,one more question with my set up is it possible to upgrade to a better controler and display,and do you have any advice which one or even a link where I could buy such a set up
Thank you sir .
Thank you sir .

Ok
You have a 48 volt battery how many ah is it ?
You buy the controller to match your battery not the other way around because your battery is dumb and must be able to match the maximum output of your battery if you buy two bigger controller it will try to demand too much from your BMS and battery you must have said earlier be under that level.
And by all at one time from the same company the same shipping package that controller and display and make sure that the controller has a self-learning wire and that way you don't have to guess what this 36 different combinations of FaZe and Hall wire connections.
Sometimes it would be just as cheap if they threw in a throttle and a pass disc all in one package. So all is plug and Play.
As I don't think you would want to be slicing wires and putting on different connectors etc etc. As you're going to buy it make it easy on yourself.
If not you can do it the old fashioned way like we used to do and had to go through all the crimping and soldering and trying to learn what the pinout is for the phase and hall wires
I'm not familiar with what you want as I do not run a PSA and use a high power controller at 72 volts.
And maybe someone can chime in here and answer your question through experience and give you the one answer you want.
Please for us all right down one time what you desire and there's a hundred people on here that can answer that question at a very reasonable price. But a lot of people in your voltage range do run the KT controller. Good luck

Thanks for your reply much appreciated really I'm a total beginner,but not frightened to try, anyway as I said it's 48v 250watt maximum 22ah fat tire I enclosed photos.
Yes I've heard of the KT controler and display I'm looking to push my fat tire to the limit really without destroying it of course.so I guess just want to upgrade.
I would really appreciate anyone who could send me a link to the right kit as they all look the same after a while,so please see the attached photos hope you can figure out for me what I need to buy and from where.
Kind regards Martin from the Netherlands

Nobody can advise you of what controller you can safely upgrade to without knowing how much current your battery can safely deliver.
If you buy a 30 amp controller and your battery is only capable of supplying 22 amps then your battery will be damaged.
Please note that amp hours (AH) is not the same as amps (A)
Also your motor must be capable of being run with an upgraded controller or it will overheat.
As said above, I also only know of the BBS controllers where you can configure the PAS in the manner that you want and they aren’t suitable for your requirement.
KT controllers deliver PAS in the same way as your existing controller. So you won’t gain anything by replacing what you already have with a 22 amp KT controller.

ebike batteries have three important parameters.
1. Voltage (V)
2. Maximum Current (A)
3. Ampere Hours (AH)
The voltage rating is the nominal voltage which in your case is 48 volts.
Ampere Hours is the capacity of the battery. For example if a battery is rated at 40 AH then it will deliver 20 amps for 2 hours. It does not necessarily mean that it will deliver 40 amps for 1 hour.
Maximum Current is the maximum amount of current that you can safely discharge from the battery. So if the maximum current of the battery is 25 amps then you can run a 22 amp controller safely without damaging the battery, but you cannot run a 30 amp controller because it will exceed the maximum current that the battery can deliver And damage can occur.
Is there a label on the battery that shows, voltage, current and capacity?

You can only get proper help if you answer the questions we ask it's getting to the point where have ask these questions in a ABC or a 123 format and you must answer all the questions so you can get the proper help need it. You can't just say I want help. Ok

As I don't want to start over from the beginning please read what all the other people are asking you and give us the information that are being asked. Ok
1. What is your location. Oh the Netherlands
This will be helpful because we'd hate to give you someone from United States or Canada as it cost a lot in shipping.

The KT controller has the best pedal response among the 3 or four controllers I've tried, so I only use KT conrtrollers now on my ebike hobby. It will not do what the guy wants, which is to give freedom to change pedal assist response independently on any PAS level.
I took the trouble to look at the manual for the display he already has, and it says it can do that. If that's true, maybe he shoud look at whay his isn't doing what it says it can do,

Ok this my battery and we know my bike has a 48v 250watt motor ,so is there and display controller out that that can install with the options to change pedal assist percentage in the settings.
