I was on the fence about ordering this because of reviews. But after getting it and putting it on my bike i realize the bad reviews are probably from people that are not mechanically inclined. You will have to most likely modify a few things so if you dont know how to use a drill for holes or an angle grinder for chopping and shortening then youre screwed and will probably write a bad review. After i put this engine on i couldnt stop riding it, it is so much fun most likely will be getting upgrades for it or saving for a 4 stroke. But overall great product definitely recommend it to anyone that is relatively smart when it comes to this sort of thing.

The packaging and first appearance was excellent but upon closer inspection and teardown if the motor I found so many things wrong with it!!! The bottom of the cylinder sleeve is cracked and missing a big chunk, the port work is hideous!!! The intake and exhaust surfaces were damaged and cast horribly to the point that there’s no way they would seal correctly… Piston was installed backwards and would probably cause motor to seize as well as break the piston rings. The hardware was finger tight throughout entire motor. The clutch bevel gear had no grease nor did the the clutch bucking bar and ball bearing.Also it was listed as an Amazon prime listing and it was shipped snail mail via FedEx and showed up several days later than expectedAlso listed as 100cc it’s closer to 70cc by my measurements and calculationsIf this thing even runs even after cleaning up the ports and crappy gasket surfaces and doesn’t self destruct I’ll be amazed🤞🤞

Overall the price is right, (if the product actually worked…) unfortunately the instructions are completely shotty, and not descriptive at all. The instructions are along the lines of (if you already know what you’re doing) and they have tiny pictures that you cannot even make out to explain the process of building the motor. And of course last but not least.. the clutch was faulty out of the box.vit barely worked at all when I got the bike running, and then suddenly without any cause the clutch stopped engaging the motor and it is not able to start due to the motor not turning over at all. If I can get it replaced for free, with absolutely ZERO extra payments it’d be fine because I know nothing is perfect and every product has issues in one or another of the productions. But! If a company is 3illing to replace for free any problematic parts, then I say it’s awesome and worth purchasing! I will post another review when I find out if and when the company will replace the motor decently.

The motor itself operates as expected (for now at least), the hardware and clutch that came in the set left a lot to be desired. My second ride in the bolts for the muffler stripped out and I almost lost it, ended up going to O’Reilly’s and found better quality hex head fasteners that fit properly. Clutch arm and hardware were also stripped out, I reached out to the customer service and they offered to replace but it would take 20 Business Days to receive, or I could buy my own and they would reimburse me. I chose the second option, for the time being it’s operating great though, not sure of the speed I’m reaching yet as I don’t have speedometer.

Clutch lever is very loose felt like it was falling apart when it came out of package I almost crashed because the lever won’t hold down I had to buy a new one also pedal won’t clear the muffler I also had to buy muffler other then that the motor seems to be just fine works really well start first try every time.had a small problem with installing rear sprocket would be much better if they had the sprocket that connects to center of rim instead of spokes for one it’s a lot safer and two would be much more easier to install without much problems I wish they had an option to customize whats needed for any particular Bicycle also add instructions to register a motorized bike legally or even add a certificate of origin because some DMVs require it
