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.

  1. That was cool but what's up with the really slow eye blinks? Also, you said the two stroke is more powerful but you maintained a higher top speed with the 4 stroke… ?

  2. Love your well done videos. Do you build motorized bikes for sale by any chance?

  3. So my question would be what will be the best frame to build a 4-stroke on beach cruiser are trail bike 90% of my riding will be on the road

  4. Okay I have a question I put together a few two strokes first time I put one together it took me about two and a half very easy to work on but now I have my mind set on a 4-stroke I'm 50 years old so I'm not into the speed I want something easy to operate since I have COPD four-stroke seem to be an easy motor to work with no paddling required to get startedmy question for you would be what will be the best frame build a trail bike are a beach cruiser

  5. Thank you for your video I enjoyed watching I think I'm going to go with the what would be the best bike to put it on a cruiser a mountain bike

  6. You should build one of the fat tire eBike kits out now … electric bikes are they are the way to go. Super dependable, silent, easy and cheap to charge and the torque is crazy.

  7. Feel like the 2 stroke should have a clutch because i know it can go faster if it has like 3 gears

  8. As quarantine measures here banned public transportation, bikes and motorcycles are becoming more commonplace now. I've seen several converted bikes before quarantine, but I guess more people will buy these as more people try to go to work despite the government trying to make it more difficult for us to go to, at least for those who can't work from home.

  9. Could you, please, put a turbo kit on that 4-stroke kit to equal the power with the 2-stroke?

  10. Too many times have heard the fable of the direction of the chain keeper…
    It can be inserted in both directions, because the chain is a "tension only" device.
    " tension " has not preferential direction.

  11. I have the $700 4 cycle engine with the 2 litre fuel tank and a round trip of 2.24 KM each way totalling 32.5 km in one week is what I got on 2 litres of fuel which is about 50 miles to the gallonwhich isn't bad compared to a scooter that does 80 miles to the gallon and with the 82 transmission that comes with the kit and sprocket for the wheel does 40 kilometres an hour with the upgraded Hunter tooth transmission and upgraded wheel sprocket it will top out at 55 kilometres an hour top speed

  12. Now what about the cops or local laws with one of these 4 strokes, Do you still need a motorcycle license, I have my drivers but its not for motorcycles, But as long as pedals are there its still a bike am i wrong. So there street legal?

  13. 2 stroke is light and powerful if it's tuned right, a 50cc 2 stroke is plenty powerful enough
    can be fast if it has a multi speed transmission
    4 strokes is just fine for cruising and fuel economy
    it has good torque at a relatively low rpm

  14. Smoke meanings there is to much oil im mix with gasoline. If you make correct mix of oil and gasoline there is no smoke
