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

KONG Tug Toy
This tug toy is decent but not amazing. It’s sturdy enough for light play, but it doesn’t hold up as well as other KONG toys we’ve used. My dog enjoyed it, but the material started to wear faster than expected, and it didn’t feel as durable as the usual KONG quality. It’s fine for occasional tug sessions, but not the best choice for strong pullers or heavy chewers.

Best toy for a puppy who loves tug-o-war
My puppy (lab/shepherd) went nuts for this toy. She loves to play tug-o-war. This is so durable and the grip handles on the end totally help you out. She loves to bit in the middle and will whip it at you to get you to engage with her. The size is perfect for her and the KONG material must feel good for her.

Kong didn't survive this guy.
He had it for an hour.. We played tug for around 10 minutes then he took it off and chewed it up.. I thought Kongs were tougher to chew up.. very dissapointed.

One of the best dog toys we've found
This is one of my little girl's favorite toys. She's an aggressive chewer so at first we followed the manufacturers instructions not to let her use as a chew toy. It was purchased in January 2025, but it's holding up just fine. She likes to turn it into a pretzel for some reason, but hey it keeps her entertained! Highly recommend.
