Are 4-Stroke Bike Kits better than 2-Stroke Kits? Let's find out!

  • In a previous video ( ), I built and tested a 2-stroke bike engine kit. For $120, it turned out to be a great kit! It does require a little bit of upkeep and maintenance. In this video, I put together a 4-stroke bike engine kit and then compare it to the 2-stroke bike engine kit. We test top speed, ease of use, noise, amount of exhaust smoke, and several other things. I purchased the kit from Amazon for $189. I don't normally provide links to the products I test, since I'm not an Amazon partner and my goal isn't to sell products. These kits are also available on many other websites. So, recommend shopping around for a better price. Thank you very much for supporting the channel by watching the commercials and through Patreon support.

    You can buy smokeless 2 stroke oil. I had it before. Same performance, zero smoke. I think AutoZone had it. Also on 2 stroke engine, vibration does suck. With no mods, I go 30mph constant. $100 kit.

    Those rag joints are garbage. You’re going to knock your wheel loose, then throw your chain.
    Buy a dedicated motor bike hub from Grubee or sickbikeparts

    The 2stroke sounded like it was maxed out to equal the 4 at the same speed. I'd like to see more about which one can burn scrap fuel better

    It's my understanding that the forks need to be reinforced
    because of the torque

    Any chance you can share a link to amazon for this? I understand you aren't a partner or anything but if someone such as yourself trusts this motor and enjoys it, I trust that more than some comments on Amazon's reviews.

    I watched both the 2-stroke bike build as well as this 4-stroke build. While you mentioned a general weight difference between the two (the 2 stroke being lighter), I didn't hear actual weight information (apologies if I missed it). I am interested to know how much each weighs i.e. how much weight to be added to the bikes?
    Another item of curiosity is how well sealed are the fuel tanks? With bicycles subject to falling over, or being laid down, I want to know that the fuel tanks are not going to leak via poor quality fuel cap vents. Along the same lines, I presume that the 2-cycle engine is not that sensitive to having been laid down sideways. How sensitive is the 4-stroke motor to change of orientation i.e. if a teen lays the bike down for any period of time, how much oil is going to work up past the piston rings or crank case vent, etc. to cause problems?
