79cc Monster 80 COMPLETE Bike Engine Kit - 4-Stroke

A bigger kit to get your bike moving. This setup includes a CNC single speed transmission with a  ⅝ shaft keyed centrifugal clutch. Using the motor gas tank and exhaust which both can be upgraded (see 79cc Monster 90 kit).

4 Stroke engine kits are very different from 2 stroke kits in many ways. Building a 4 stroke bike is a little more involved then the two strokes, the extra effort is worth it. Pull start engine, not push start like the 2 strokes. Overall this type of engine is more reliable with more power and torque. With some of the larger cc motors, the top speeds far exceed the 2 strokes. Since these motors are larger in cc they are also larger in size and weight. Almost all bicycles will need to use a wider crank setup to clear the motor, the stock arms and pedals will hit the motor when pedaled as a regular bike. One piece cranks will also require a bottom bracket conversion set as well (not included).

This style of the engine might need slight modification to the bikes and will not fit all frames.

Advantages of 4 Stroke Bicycle engine kits:

  • Use straight gas (no mixing oil with gas)
  • More Horsepower
  • More Torque
  • Quieter Engine

Ok
Color: Dark Teal, Size: King
Looks pretty but not on my bed. It constantly looks messy. I don’t like the lack of neatness.

Couple Win
Color: Spa Blue, Size: King
The Amazon Basics Lightweight Soft King Size Comforter has been a wonderful purchase for our home! The comforter is incredibly soft, comes in beautiful colors, and is the perfect lightweight option for year-round use. My husband and I have very different sleep preferences—I tend to run hot while he’s always cold—but this comforter somehow works perfectly for both of us. It’s breathable enough that I stay comfortable while still providing enough warmth for him. We finally started sharing the same blanket again, which is a win in itself! Highly recommend for couples with different temperature preferences. 🛏️💕✨

Light Weight but Not Hot
Color: Dark Grey, Size: King
Ok... I absolutely love this comforter. In fact, I use it on three different beds. The colors are perfect. The material is soft. It's extremely light weight, but it keeps you warm in the winter and does not overheat you in the summer. I have this in King and Queen, and the sizing has been good for both. I have thrown it in my washing machine multiple times, and it holds up well. Great quality, low price.

Navy is pretty, but doesn’t feel like a great quality set.
Color: Navy Blue, Size: King
I purchased the Navy. The color is great and the pleated pattern is a nice touch. My daughter has the white and it’s very soft. The navy is not, though. So that was disappointing. It’s also not breathable. It’s not thick, but just not breathable. I actually get pretty warm at night with this one when I don’t normally with any other blankets. It also seems on the small side. We have a king and always buy king, this just feels a little smaller. Doesn’t feel high quality. I would not buy again.
