HGC 1.0" Compatible Pad For 1.5 Inch CNC Sprocket Adaptor For 1.5" Adaptor 1.5" Hub 60cc 66cc 80cc Motorized Bike (Silver)

To be honest I thought the center of these when put together was supposed to be circular but the ones I got wasn't. I didn't say anything but I couldn't use them so I tossed them away.

They work perfect

I will give this shim a 5 star for price but not fitting on my hub from a mongoose dolomite I don't know what to rate for that, but I did figure out what could be done to make it fit to use a carbide but slowly and fit onto my hub until it completely fits into place. If you are a diyer for motorized bicycles no mater it's gas or electric be prepared to make certain parts work when you can't make the part yourself

HAd to fabricate with an angle grinder fitment issues

easy to use

OUT OF ROUND

Fit as advertised

Measured my hub with calipers. Came to 1.000 +/-. 005. When I set it on the hub they were clearly different radius'. Got it sorted by cutting up a top tube of old bike to make inner shims. See the pink pieces. Couldn't quite get the bolts to start even though everything seemed to fit. Decided to stud it. Used the longest bolts with threads all the way a cut the head off. Trimmed about 3/8" off the top to make it work. That's a Walmart rim and the cheap Kimball adapter, so I didn't mind it hacked up some. I have a nicer 12g wheel. Also 1" Hub, longer studs on the way.Don't know how anyone got it it to fit perfectly. Unless I somehow got the wrong size 🤔

It worked flawlessly on my 1” hub, works good for the 1.5” hub sprocket adapters.

Too small doesn't work

Not 1" ID. About 1.005Also oval in shape.
