So for its the best motor

I can't think of anything I dislike about this kit. It out did what was advertised. I will recommending it to everyone that asks me.


I had a small issue, I contacted the manufacturer and they worked with me until I had my issue resolved. Courteous, efficient, and commendable service of the highest quality.

Easy installation, great quality

Bought this for my husband, who is happily riding his motorized bicycle as I type this. He says it was great value for the money, the installation was fast and easy, and the parts were of good quality. He says that he will be buying more for future builds.

Matt Farr
Great communication with seller, and a solid product.

I bought this to install for a project, and a project is what I got! Everything is great and it works great.

The best for your money

Great engine runs runs great.

The manufacturer is stepping up their game!

I got a kit, but a part was missing, and the engine had poor compression. The seller quickly resolved these issues and delivered a slightly nicer engine this time. The finish was nice and shiny (but with noticeable overspray), had more rounded covers than the old one in the pictures, and the exhaust port even appeared as though it had already been polished! I had to bang the holy heck out of my muffler with a mallet (OFF of the engine, of course) to get my vintage cranks to clear it, which chipped the high temp paint on the muffler, but no harm, no foul. The rest is a breeze! Make sure you have some red and tacky on hand; mine had no grease on the gears unlike the older one!

Now for the good part: I ride in NM at 6000 feet above sea level. I put 25:1 in the tank and she started right up and took off! So far, I got her up to 30MPH with more breath to spare, but I weigh 100 lbs. soaking wet. I get a crisp, clean two-stroke "angry bee" tone with no "four-stroking". I haven't even adjusted the carb yet.

I'm still breaking her, so I can't say about the endurance or my top speed yet, but its plenty powerful and has no problems starting and providing near instant low and mid power with very little smoke.

Yes, it's a China-doll, but it's a good China-doll, and an absolute blast to ride! Take care of her and she'll take care of you!

Poor Instructions

Everything works as it should but poor instructions. Needed to look up YouTube video, otherwise would have given 5 stars.

Tyler Lewallen
Good for beginners

Have had this motor kit since December 2021 and today is 5/16/2023 and it still works great! Was my first bike kit so I definitely recommend!

Good but don't know about the future of it

Loved putting it together and runs greats but the clutch locking pin fell out after only 2 rides. And can't be put back in.

Engine Quit

Engine lasted about 2 30 minute rides and it locked up. Junk. Mixed the fuel and oil just like it said, 16:1 for breaking in. Compression is totally gone now and it won't even fire. It was a blast to ride until it was toast with maybe 30 miles on it.

Update: changed to 3 stars because the seller refunded my order so that was good of them. Still would not buy this product again though, spend a little more money for a better kit.
