44T Sprocket 1.5in Blue CNC Adapter for 415 Chain Motorized Bicycle 50cc 60cc 80cc

Amazing.

Grips onto hub very well! Fits well and seems made of good quality material. Easy enough to install literally 2 bolts and 3 for the sprocket, spacing was good.

Hub worked great the gear did not mate with the chain I was using on a 4 stroke gas bike kit. Drilled sprocket that came with the engine kit and used hub mount. High quality works great.

Does not work straight out of the box! Some fab work needs to be done THEN it's awesome. I had to grind down where the mating surfaces meet about 2mm on each side so that there was a small gap in-between the top and bottom piece so it could really clamp down on the hub. After mods, it's really great. DO NOT USE THE RUBBER GASKET. I did that originally and I ended up killing 6 of my spokes because the rubber squeezed out from the bracket and everything got loose. 29inch BMX, 25mm hub, fitbikeco.

Super duper duperrrrr thx so much

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.

I tried to order this product to install on my mountain bike with my new motor kit. For one it didn’t have the right hardware meaning screws bolts call them what you will but I got this sprocket that was what looked like to me is very scratched the bolts didn’t fit the holes. Now not only is my bike not finished but I’m waiting on my money to come back to my account. When I went to take the product back at the store the female working told me I needed it boxed up and labeled and that put me back even further than I was to get my mountain bike motor kit to go on my bike. There’s a reason I’m putting a motor on my bike it’s to make my traveling easier obviously that’s not happening and now I’m waiting on my monry

Or on most that you can buy a promoter's bike the inner hole is not designed for coastal brakes and the whole has to be boiled out to 2 and 1/4 inch The next problem I found was that the boats did not have locking threads on it or washes and lock nuts so every bolt wont come lose on the gear came loose and broke my new chain on bike.

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

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 nicely Recommended 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

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.
