I put together a Voilamart 1500watt/48volt rear hub kit that has a SW900 LCD display and a controller built into the hub. It takes just the slightest turn of the throttle to almost pop a wheelie. It can be kind of dangerous when going slow or starting out. Is there anyway to reduce the sensitivity in the twist throttle? I contacted the manufacture and so far nothing on this. I read through the manual but didn’t see anything that might help.
thanks

I don't know, but this link

seems to suggest there is open source software available to reprogram it. There also appears to be an SW900 display that is programmable as well.

suggests a different controller. Might be a bit of a super nerd project to do though.

If you gain a stone of weight, it should help the problem. Also, lean into the acceleration to avoid the kick?

Uriahsky

Thanks everyone. I will read up on those links and if nothing for sure comes of it I will just adapt. It I not that bad. And I have been at 250lbs, no fun there.

You want to be looking for a term called 'ramp', maybe 'acceleration ramp' in the advanced settings. It should be user adjustable. A longer ramp lengthens the time it takes for the power to build.

Uriahsky

I. Have been digging through the manual and there are advanced settings but no ramp or acceleration. Have you done this with a sw900? Maybe I am missing it? I still can’t get the people who sold it to me to answer this one.
thanks

do you have PAS? Looks like zero mode/non zero mode might help a little. Also, current limit might help.

Uriahsky

Yes, it has PAS. I think I have gone through those different settings When riding but I will try it again on the next trip. I will look into the current limit also, I also thought maybe that might help but I figured it would just reduce the overall power and I still want to go as fast as I can, when I can. I will read up.

thanks

Since you have PAS, set it on the lowest setting. Then from a stop begin to move the bike forward by pedaling, not by the throttle. Within a couple turns of the crank the motor will kick in but since you are already moving you will not experience the "wheelie" effect. Then you can add throttle or higher PAS settings as you desire.

there is a zero mode that does exactly that, PAS first and then throttle
