vanpro DIY Electric Skateboard 83MM 90MM 97MM PU Wheel Pulleys Kit Set

These can be tricky to center with the wheels since they aren’t designed for this, but they do fit with some patience. Good sprocket set, everything came in the package and everything fit. The only thing I would say is a minus is the motor gear that is included is 12 tooth, most other diy companies use 15 or 16 tooth for the motor gear. Not sure why this is. Will update later for ride quality.

The don’t work for any of the newmatic hubs

So I'm not completely happy but I did get it to work. I'm building an electric skateboard right now and the problem wasn't in the application but in the assembly. I couldn't get the screws through the holes in the outside plate to go through my wheels. I had to take a drill bit and kind of ream out the holes to get the screws to go through. Then, I had to grind down my caliber trucks so that the wheel can actually spin. I took pictures so anyone can see but I am getting it to work with modification. I have 90mm flywheel which it said it would work but I'm just glad I have the necessary tools. But now that I know how, I might order another pair for the opposite side. But if I ever do this again on a different skateboard, I'll go with something else.

The media could not be loaded. Used these to upgrade the spindle drive for my taig milling machine, great price for a couple of HTD pulleys belt and hardware.

Let me preface this with, this product of working fine for me and hasn't had any performance or structural issues. I am not sure what you would use half of the ( wheel mounting the gears were fine ) hardware for I was given two sets of screws( sets of 7 ) standoffs, and a ring with holes in it. Issues are the ring does not fit any of the screws so I don't think I can use it no matter what wheels I was using the angled part of the large gear makes it difficult to put the screws in without scraping some threads. also this does not really fit a caliber 2 truck right up against the axel, it scrapes the the hanger so I had to use 5-6 washers to get it to be far enough away, you could file the hanger a bit to get a good fit. In short the overall mounting feels pretty janky and the gears threads are not the best but it has been holding up and for the price it works for me.

I am running the MBS al terrain wheels on my custom electric long board. This pulley works perfect!!

Screws don't fit through the outer black ring. I tried drilling it out with a drill bit, but the steel is so hard that it broke my drill bit in half. I don't understand why the screws don't fit through the outer ring in the first place? They literally came packaged together and it doesn't fit?

This kit was a great kit, everything listed was in the kit and craftsmanship was good. However for my application (single drive 6370/149k 6s with 113mm wheels) was too much torque for the belt. I stripped the belt that came with it in about 200 feet, I purchased a couple of wider belts and they lasted only a couple of miles and two hills before stripping.If you don't have as much torque as I do that you can get to speed in for seconds going up a steep hill, you will probably be good with this kit. If not get an open gear drive, and never but a belt again.
