Re: Conversion of a Bultaco Sherpa

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.....

Re: Electric Roadster

Looks awesome. :bigthumb:

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.

Re: Yamaha XS400 conversion

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.&...

Re: Conversion of a Bultaco Sherpa

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)...

Re: Voltage selection

Thanks for the great reply :lol:

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.

Re: Should the charger be "on-board" or not?

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...

Re: Yamaha YZF250F

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 ...
