110cc motorI 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 🙃😉🙂

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

I just got this for my birthday and then spent the next two days fitting it all in my bike. The instructions leave a lot to be desired and since my bike had a really thick frame I had to macgyver it a bunch to get it on to my bike but was fairly straight forward. This engine has got some real power I couldn’t get an accurate top speed but I estimate it to be around 30-35 MPH stock. That being said DO NOT RIDE WITH THIS ENGINE WITHOUT DISK BRAKES. My dumba$$ nearly killed myself😂. Another thing is the chain that comes with it is incredibly weak and the master link snapped after about two rides and I had to get a new chain. 4/5 would buy again.

All parts came as mentioned. Good quality. Everything fit snug except for muffler which I had the torch and bend so it's out of the way of my left pedal. Came with BoFeng carburetor, which I prefer. Great price..ðŸ‘ðŸ‘ðŸ‘

I bought this bike because I wanted something fun to ride. And it fulfilled that purpose. It's really fun and goes around 25-28 mph. I think I am going to make this a project and add more things to it to make it faster. I am going to add a performance carburetor and a better exhuast, and MOST IMPORTANT YOU WILL NEED DISK BREAKS NO MATTER WHAT THE NORMAL BREAKS ON BIKE ARE TOO BAD, BUT DON'T GET THEM IF YOU WANNA CRASH. Do I recommend this? Yes. Even for people that can't afford a car. But if you are going to use it on a daily basis, you should upgrade it with the things I listed above.

Runs great other than a small exhaust leak in the head easy fix.
