New Wheel Sprocket 40T 40Tooth Motorized Gas Cycle Bicycle 50cc 60cc 80cc

In the past I have used the stock 44T or 36T sprockets and with either of them performance suffered I either had no take off and good top speed...or no good high speeds and great take off. This 40T is the best midline of both take off and top speed. I only need pedal very little to get over the top of the biggest hills and still cruise at just over 30mph without the engine rpms over reving. This makes my beach cruiser custom ride like a dream.

I have a 29" bike, with an 80cc motor. I was able to get up to 42 mph with this sprocket. The build seems sturdy, unlike my wheel spokes. 😂

You will have to make some additional holes (3/6 will work just fine) and you will have to make the center hole slightly larger, but it works just fine

doesn’t fit i had to drill the holes out and rig something up

Went from a 44 tooth to this 40 tooth making my engine on my motorbike less stressed. I don't have to rev the engine as high to go the same speed. It's just better for my engine overall.

I’m a heavyset guy, but I have a pretty powerful motor on my bike. 36t is pushing it with hills and getting going from a stop, 44t is sacrificing too much too end. 40t is the perfect middle ground. Enough grunt to take me from a stop with minimal if any pedaling as well as no trouble climbing hills, and I top out around 40mph. Me gusta.

good quality ring! 40 is my favorite ratio. not too high.still a thrill in the hills

All things considered it looks pretty good. Its not perfect but its flat, and true before I put on the bike. This is a thicker sprocket and you will need to make sure the wheel and motor are lined up perfectly otherwise the chain might bind. Its for sure much heavier duty than the stock sprocket but this might throw off the alignment if you had it perfect before. I used my old rag joint hardware and it lined up fine.

this gear works great one thing to keep in mind most bike frames are not all made the same some mods might be nessary i had to place anouther wheel nut on axel to space the frame out so the chain will not rub,it was cheap easy fix for thes large gear that fit mage wheel perffectly.

Good quality sprocket. Heavy duty steel. Love it. Thanks.

This sprocket is better quality than the sprockets that come with the bicycle 2 stroke motor kits. However it is just as difficult to install as the kit sprockets.

Hey it was cheap and it works perfect. Definitely worth the money to buy.

Best tooth count. Great top speed and still good low end. I just hit 63khm and i hit 53kmh with a 44 tooth. Quality is decent and lots of hole options. Great piece.
