1"/1.5"(25mm/38mm) Silver CNC Adapter 40T Sprocket Fits 80cc Motorized Bicycle

I really like how well this fit around the rear hub of my 26 inch cruiser. It fit Tightly without any slippage. Not to mention it was worlds easier than using the basic 9 bolt sprockets That come with the motor kits. Functions perfectly right out the gate without any of the headaches you could run into having to balance the stock sprocket that comes with the motors.

This product is exactly as advertised and all materials are well made and delivered was fast too. Thanks.

Good product makes the sprocket perfectly centered only thing is it slips if not tight enough and I mean tight tight

Who knew? Not me!Very nicely made, and finished. It appears to be clear anodized all over as well, which will keep corrosion in check. I just wish I could have bolted them straight on.I bought a set of wheelmaster rims for my 20yo Schwinn Del Mar beach cruiser. It had a 1-1/2" hub so I assumed my new ones would too ...there's my problem...The wheelmaster rear coaster brake hub is 44mm which is basically 5/16" digger in diameter (just under 1-3/4"), so I'll need to find a shop to bore the adapter. If someone makes one, I didn't find it, so something to keep in mind.

Very simple installation. A must have if you’re building a motorized bike and don’t want to fool with the rag joint the kits come with.

Fit just right on my sons motorbike he built with bicycle frame

Buena calida

Great for motorized bicycles. Heavy duty. I'll never go back to a rag joint again.

This sprocket is perfect being a light weight guy I can still feather the Throttle and clutch and get her going from a stop maybe a quarter turn push on the pedal and the top end speed feels so much more natural and fun compared to the stock sprocket,I do miss the wheelies though and trail riding but with different environment comes with the opportunity to try different sprockets the hub adapter was a little finicky with the wheels I had on but otherwise it worked nicelyRecommended for more heavyset individuals as well, just because I said I’m lightweight doesn’t mean a bigger guy can’t get speed. I’ve seen a lot of bigger guys get away with riding with this setup on my bike and they all had a blast

Don't waste ur money the hole in the middle is way to small and the little holes are so close I can't even make the big hole in the middle bigger and the bolts arnt set in so they stick out too far .it's unusable

Didnt work

If you bought a multi speed mountain bike from Canadian tire/Walmart it will not fit your rear wheel. So, CCM, Supercycle, you'll need the rag joint sprocket. The frame will take a 80CC 2 stroke motor, but the rear wheel will not work with this adapter.
