First of all: I made a mistake when i posted the link to the controller manual this is the correct one: https://kellycontroller.com/wp-content/uploads/kls-nm/KellyKLS-N-UserManualV2.7.pdf (I thought you were using a KSL instead of a KLS, little difference in the name, but big in the what are they.....

Looks awesome.

Too bad you are in Shanghai....

I am imagining some kind of battery cover for my Bultaco, too -
in my mind it would be something like what you made there,
just continuing the form of the former gas tank downwards.

Hummers use portal axles to obtain ground clearance.

Hummers... LOL

Real portal axles are to be found in UNIMOGs:

Have a look at my build thread for more info:

(NEW: better take care from who you buy...)

I got a reply from QS. Very interesting. Here a quote of the most important parts: " We're Taizhou Quanshun Motor Co., Ltd., QS Motor in short, now our company name change to Taizhou Quanshun Electric Drive Technology Co., Ltd. SiAECOSYS (SIA in short) is the sub-brand of QSMOTOR, who focus on ...

I don't think so, because eventually the rotor would lock up and the tire would skid. The torque would never go above the amount required to lock up the rear wheel. With a sprocket the torque can go higher. I think, "amberwolf" is right. As a general rule, in a street legal vehicle, brake...

And one more question: Can anyone explain me, what this "3 Speed Switch" on the throttle is supposed to do? In the Kelly Controller Manual, I find this: "(23)Three Gears switch: It is used for function of F-N-R control. Please check the wiring diagram in the manual for F-N-R control.&...

How shall I know which of the 6 cables of the display serves which purpose? You need them to tell you what is what in that, else there is many chances you destroy it during process. Probably you got this connections: - Ground - Positive (Here it will read if the vehicle is on/off and battery state)...

Thanks for the great reply

As for my question:
Yes, the controller and motor just work with whatever they get from the battery.
(of course within their specifications)
I tried it with 48 V and 60 V until now.

Now, after I got the controller/motor/throttle combo working, I received an email from QS, confirming that I just need to put together the 6 wire plugs of Motor and Controller, regardless of the wire colors... They also answered my question about the display, but not as I wished. I am quoting: "...

I will not fix a charger to my planned build. I suppose, in most cases I will not need (or have the possibility ) to charge if I am not at home. IF there will be need and opportunity, I will simply take my charger with me. All my bicycles and motorbikes (electric or not) have a place where I can tra...

I also think the points " thoroughbred " made about the "NC" and "B+" connectors are reasonable. Indeed the screw labelled "B+" was fixed, and the one on "NC" was loose. So today I connected the necessary cables, as " Dui, ni shuo de dui " ...

I hope this is enough room..

Looks good to me !

Took some pics outside: .... The first saddle I made using the silicone clearly wasn't comfortable enough, so I'll make another one, a bit thicker with a slightly different shape. Aside from that so far everything's fine, the frame and the powertrain are done! Looks really awesome. I wish I were al...

A little side quest yesterday: I designed and printed a little enclosure for the BMS screen.
Nothing really fancy, ...

If this is "nothing really fancy", I am curious to see what you call "really fancy"
I find it quite impressive.

Here is the manual for your controller: https://kellycontroller.com/wp-content/uploads/ksl/KellyKSLUserManual.pdf Thanks again :) Hmm... This is the 4th version of the manual now... I have "KellyKLS-M-N-UserManualV2.5", KellyKLS-M-N-UserManualV2.6" , "KellyKLS-M-N-UserManualV2.7...

[/size]Thank you again for the reply :bigthumb: We can't see anything on your picture, so I really cannot say. Only thing that really matters on this plug is to have the red on the red and the black on the black. The other colors are not important. OK, here are two new pics, from the both sides of t...

And in order to help you to setup the controller here you have link to some videos I made about it with Kelly-KLS controllers:

¡muchísimas gracias!

(discúlpame para el feo portaequipajes en mi bultaco - estoy muy satisfecho que me ayudas sin embargo )

Thanks again for the replies. I am beginning to understand a few things. I have written to QS motors and they replied: "We have matched the controller and motor already, so you just need to connect it and work, but if you need to adjust some datas in the controller" I understand this so th...

QS Motors:
Ordered and paid 3.2. (Air freight by FeEx)
Arrived 22.2.

Thanks for all the answers. So I suppose I have to look for an android phone app on the Kelly homepage for setting up the controller... As you can see from my questions, I am an absolute beginner in e-motorbikes (all I did until now was building two electric bicycles, but this was using complete con...

Today the parcel from QS China has arrived, finally... And the questions arise. First of all: I got absolutely NO documentation. I wanted to make the conversion with 48 V and ordered the components for that. The Controller has a decal saying 40-90V, so this seems OK. But on the motor is a print sayi...

While I am still waiting for my parcel from China (now announced for Monday 22nd...), I am trying to get some basic understanding about the cooperation of battery, controller and motor. The kit I have ordered from QS includes (amongst others) a QS138 mid motor and a Kelly Controller KLS7245N. The co...

Today the parts from China should have arrived (thats what FedEx said). But they are still in Shanghai- already lying there 8 days without moving, if I can trust FedEx's tracking page. Today FedEx finally answered my email (after 48 hours instead of 24 hours, as they write on their page :lol: ): Due...

Do you really think a tensioner will be necessary for this short chain? I am trying to avoid it, to have less things that can brake.. The motor is movable back and forth to adjust tension. The chain will also be in an oil bath, so I dont think it will wear very fast. It has room to move everywhere ...
