Gearing/ pulleys

I am really trying to grasp pulley set up but it’s hard to get. I understand the larger pulley the more torque lower top speed concept. How without spending tons of money on all the sizes do you pick them out. I have done the esk8 calc playing around but I know wheel size and motor pulley size all play into the right size for a set up.

Example, most of the set up I played with all top out at 30+ mph, I really do not foresee myself doing 30 plus. So go with more torque set up? What I don’t get is will it take forever to get to my desired speed if I go that route?
Setup I am looking at,
TB110 wheels
15/36
15/40
15/44
16/40
16/44

Well first of all, you can always limit your speed if you want, if not, you don’t have to ride that fast.

When I ran dual 6355 I found that 15 40 is a great torque combo on the 110’s. Sacrificing some speed for more torque, 15 44 or 16 44 would give you heaps of torque

More torque = more acceleration, which means faster to get to your desired speed. Conversely, if you gear for speed, it will take longer to get to that speed at the same input power number

Torque > top speed that I will hardly reach
So for me, its always pick the larger wheel pulley and change the motor pulley if i need more speed, which never actually happen lol

So if I went the 44 tooth route would the 15 or 16 tooth motor pulley give the more speed? I have a 15 tooth right now.

I’m not really worried about top speed as much I just don’t want a slow to get to desired speed set up.

Without changing wheel pulley, to get higher top speed, either change the motor pulley or change to a higher kv motor

Play with the skate calc. I run 15/36 on 110’s and it’s faster than I need, but it still pulls hard since it’s dual 74’s. I may still swap to 40T wheel to get a bit better efficiency.

I’ve played with that but since it’s still on build it’s hard to figure out without feeling what I need, so 40 would be betterthan 44 for all-round use?

You can go well over 30mph with 44T if you need, I would go for that.

15/44 is your friend. Maybe 16/44 second choice. IMHO

Gearing for more torque, first and foremost gives you more torque, which feels amazing. But aside from that, it also can increase your range, decrease accidents (by allowing faster stopping, and lower top speeds, etc) and stress your battery less which makes it last longer.

It’s also a cheap and fast change to increase top speed if needed (change motor pulley and belt) but it’s hard and expensive to go the other direction.

And furthermore, lower gearing works better sensorless and that increases reliability.

So I’d go 15/44.

Thanks for the explanation, I really appreciate the help. 44 it is!

Conversely I run 18t or 20t motor pulley and 40t wheel pulley on TB110s, you can always make up for sluggish acceleration using more current (providing the entire system can handle it) but you cant increase your top speed by changing software parameters.
