Ah sorry. Edited link.
Adapter is to help align the wheel gear and to allow the wheel itself not to be bolted to the gear.
Will share once I have tested a little more…

is there a calculator like we have for belts, but for gears. because i have no clue how to calculate the needed distance.
Since people don’t want to 3D print the pulley or don’t have access to a 3D printer. I made an adapter to use with vex robotics versa pulley. It’s a much smaller part to print and won’t take a lot of money. I have ordered a couple of vex robotics 60T pulley to show you guys how it fits. I can send them to whoever’s interested. Pay me shipping + what I paid for.

duude you are the man. i am probably going to use a reshipping service to get vex pulleys to germany, before the mad max brexit happens. @mishrasubhransu where are you located?
I’ll DM you.
Here’s my Delrin cnc router solution…,
Nice! I like that you are using all 6 screws. Maybe I’ll update my design.
Do you have a pic of your cnc router? How much did it cost?
Thanks! The router belongs to the school I work for… it was around £4K and is not the best! It copes with Delrin well enough though.
Problem I am having is these wheels drink battery juice for breakfast!! I was expecting 20km range on my mini AT build, looks to me like I will only get about 15km.
I noticed a ~50% increase in energy consumption compared to my 83mm 75A Flywheels. Definitely worth it for the softer ride (the roads are really bad in my area).
What PSI are your wheels inflated to?
Wow 50% is bad!! But yes seems about right…
I have these at maximum PSI of 70.
Double the energy consumption for pneumatics has been the rule of thumb for like 2 years now.
So it works. Works pretty well. The vex pulley adapter is just 1cu inch. So probably less than a dollar to print. Now if only I had a motor to test everything.
I’ve used m4 bolts and I can’t find any m4 nuts that sit in the vex pulley nicely… I hate using imperial parts but it looks like the way to go!
Was the pulley 3dprinted?
No, I bought it from these guys,
Seems i am late. The prices rised a lot
what price?
Not 69$ for 4 wheels anymore. I see 18.72€ each
you can still get them cheaper, but there is a difference. The one version that is cheaper can only take 40psi and the slightly pricier can take 70psi.
Hi Guys,
I wonder if these tyres will fit these cheap rims. They may reduce the rolling resistance and increase battery as there is less tyre in contact with the road.
