Choosing motor pulley


#1

Hello
I need to choose timing pulley for single motor (sk3 6374 192kv) with 6s battery
9mm / 12mm / 15mm which one is the best ?
thanks


#2

For a single drive you want 12mm or higher (if you can find it). 12 is fine. i thought your question was about gearing not belt width


#3

12mm will work fine, 15 to be safe.
9mm on single drive works unless you got a lot of hills in your area.


#4

9mm also works on hills if gentle with the throttle and sub 70kg


#5

OK so which 12mm pulley is good for this wheels : https://www.yocaher.com/product/hd7-longboard-black?gfid=p1191-o1570 ?

what are the benefits of a thinner belt?


#7

I’m just gathering my parts for a build and came across this site, they will alter pulley bores and make specific pulleys and belts to order…Cheap. http://www.beltingonline.com/


#8

less drag 4200000000000000


#9

Less friction and the possibility of using two bigger motors because not so much space is used up by the belts


#10

ah, I’m running a dual diag setup but i couldn’t find >9mm kegel wheel pulleys so i just stuck with 9’s

I’m 85kg, have hills in the area and generally go easy on the throttle in favor of range. I have no problems with a 9mm belt except for some occasional skipping when hard braking.
