36 Teeth Drive Pulley Kit Flywheel Parts 12mm Belt Motor Gear Bolts Retainer DIY for 83mm 90mm 97mm 100mm Wheels Electric Skateboard

The item was pretty good I used it on my Hundred mm flywheel for my electric skateboard I'm building, the only thing was the holes in the front in the back on my flywheel I had to shave off a little bit of the inside for the wheel to go all the way in the second sets of screws.. to get around all of that just put three screws in the front and screw 3 in the back of the wheel..

DIYE excellent customer service is 2nd to none. I expressed my concerns about the belt and DIYE reached out to me to let me know they are addressing it. Drive pulley kit works as it should. Can not go wrong with this purchase.

This looks to be a great product. Attached to the flywheels very easily but when I went to install the wheels they don't fit with the Caliber II trucks. I want to say that they work with Paris trucks but cant say for sure. Overall i'm happy with the product but disappointed in compatibility.

My DIY project called for a motorized skateboard to pan a camera, a dolly-zoom effect. This kit of parts along with an 80mm Rollerblade wheels was perfect for that.

I did a rebuild on my electric skateboard and picked up some new parts. These pulleys, these trucks (https://smile.amazon.com/gp/product/B00NY3Q5Q8/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1), and these motor mounts (https://smile.amazon.com/gp/product/B073C6TJC5/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1) see their listing for their reviews.Anyway, these pulleys worked our pretty good. They were an upgrade from my plastic ones and were a great price. Simple to set up on the wheel but proved a little difficult to get rolling perfectly without a slight wobble, in the end they really don't need to be perfect any way. Also don't over tighten them or you will start to bend the little plate that goes on the outside of the wheel and make sure to tighten then a little at a time bouncing back and forth between ones to get it evenly tight.When it came to mounting it on the trucks is where there was a slight tolerance issue. The inside on the pulley just barley hit the truck. This was not that big of an issue though if you have a dremel, you can also use a file. If using a dremel use the WOOD bits, aluminum is soft and will clog other bits. After removing the little bit of material they rolled with out a problem. Well, that is until I put the motor mount on. That slight wobble I mentioned before came to cause a little issue here. After tightening everything down the pulley slightly hit one screw. If you have this issue, which you might not, it can be resolved in a number of ways. You could pull out the dremel again, try moving the pulley mount in on the truck some more if you can (which I could not), or do what I did and simply added another washer to the truck to add a little more space.In the end everything worked out great though.

The pulley teeth actually lasted me only a week of riding < 10 milesEdit: However, their customer service is AMAZING. Resent me new belts to replace my old one

I purchased this product and overall everything works after 20 Miles on the belt it snapped I’m disappointed I’m having a difficult time finding a replacement belt will update my review if I find a replacement

There is no notch for the kewway to go through which basically makes the motor useless because it spins without the pulley spinning
