  • Do NOT use pre-mix 50 to 1 fuel. 20 to 1 is the proper mix. Premium fuel works best for top speed.
Style: Silver 80cc
Well packaged and complete. This kit has the right fuel petcock for the bike. My last 3 orders from other vendors all arrived with dented tanks and sub standard parts. The chain on the last one I bought broke before I even drove a mile. The engine started right up without being choked and it is powerful I am very happy with my purchase. ... show more

  • Don't buy the red one...
Style: Red 80cc
I had bought this engine thinking that it was well made I was wrong. First off the thing had spray paint inside the cylinder and came locked up. I do not recommend.

  • Inspect before install
Style: Silver 100cc
The media could not be loaded. Inspect parts and engine before installing. my gas tank arrived rusted inside, but I fixed it with vinegar. The clutch cover came with a gash on bottom that I filled in with gasket maker. The engine had some small dust and bits of metal inside so I removed jug and cleaned it also grinded off the casting on intake and exhaust ports with a rotary. I ordered 100cc silver. Idk if it’s actually 100cc. As the engine just has a picture of a parrot where the displacement should be marked haha. starting it first time took a long time with long stretches of hills, but it’s doing good now, very fun to ride literally anywhere. all controls work. Starts easy now, had to do some idle adjustment on the carb, I hate the chain cover. ... show more

  • Started the very first time and have already logged over 100 miles
Style: Silver 110cc
This motor and kit is so fantastic. Starts everytime no problem. It has good performance even with the muffler on (my muffler fell off my previous moped and while it increased the HP and made my moped go faster is was too loud). Worth every penny and then some.

  • Engine problems
Style: Silver 110cc
So, building the engine and getting it on is pretty decent, startup you need a lot of stamina for and also it's prone to flooding itself out on startup. Problem is, after two weeks of running the engine to go to work (8 miles a day round trip) it siezed up, and I can't even use my bike until I take the engine off. When it ran, it ran great, that's why I'm not putting 1 star ... show more

  • Motor fit for 230lbs man, can carry you any distance
Style: Silver 110cc
110cc motor I found this bike back in March 2024 through Facebook marketplace, with a 100cc motor advertised. This motor is 2/3 larger than the one it came with, which has me questioning the Facebook seller. When buying a motor for a bicycle, or one with a motor already on it, keep in mind that you're learning a skill - the mechanical ability to perform upkeep!! 😉 Always carry the tools to work on the whole bike while out riding/traveling the distance, this is a must unless you enjoy long walks pushing a bike. Mixing the oil with the gas, before it goes into the tank, is a must as well. Otherwise, you'll have to hit the fuel release because the oil goes to the bottom of the tank if added after or during fueling. I've taken this motor+bike on a 20mi round trip tour and a 35mi round trip tour with only the basic nut/bolt re-tightening maintenance required and mixing fuel with oil to put into the gas tank. Today I ordered new brake/turn lights, rear view mirrors, and not required personal/useful accessories. I also have a 36-tooth gear on my rear wheel and not the 42-tooth gear that came with the bike. Safe Travels, Paul 🙃😉🙂 ... show more
