    There's a kid on the block who says he had to make the tough decision between the one wheel and a car, he got the one wheel, one big flaw with that kinda thinking at that age especially --- they really don't attract to many young ladies lol

    My BR600 blower pushes my canoe along at a good clip... but it's misery when the tube flips around sideways... nearly disaster.. never lock the throttle! lol

    NO stupid umbrella of course...

    This guy's jet turbine leaf blower generates 50+ pounds of thrust, and would certainly take him on a wild ride if he were wearing roller skates or a bicycle.

    Sorry - NOT! fake yes - but debating the finer details of "how" does not put anyone on "the hook"...

    yeah kid's the spittin image of Mr. Bean lol

    Ha Ha Ha Priceless!
    I swear that kid looks like a young Mr. Bean.
    Good find.

    Yes to reiterate I already stated that --- but look how little speed he loses "if any" for the duration of the coast,,, Like I also stated it's the best demonstration he could do in such little space as it would take forever for the bike to hit it's equilibrium point, take the vid along with you for one straight run somewhere to achieve this? then how would we know he's not heading downhill?

    think he could achieve those kinda coasting results without the blower and going both ways? not a chance... iv been riding knobby tired bikes for many decades and can tell you the second you stop pedaling is the second you start NOTICEABLY losing speed.....
    Man, that guy has you on the hook. Everything about the video is fake. But, if you want more proof, here's an extended video where a kid steals his rig and motors along with the leaf blower pointed forward but not even close to the umbrella:

    Ughh I put myself through it one more time --- im beginning to hate that guy lol

    I can't tell if it's the throttle control for the blower or if he also mounted something else by it? when I freeze the vid it goes to a slightly darker mode.... I hope he's not getting paid every time I view it cuz even if just 1/10th of a penny I do not want to contribute anymore.... lol

    I would not say that...

    Calculate the thrust. The results will put things in perspective.

    I would not say that, they are indeed "low torque" output propulsion, meaning a mere pebble could stop one from taking off from a dead stop, but once going they will build on the momentum to a degree, anotherwords "if" one is even capable of budging on flat ground then it will continue to slightly build upon that till the equilibrium of wheel friction and oncoming wind drag matches the propulsion output and you end up with your "final score",,, I think a powerful one strapped to an efficient road bicycle would yield propulsion results on totally level ground with a light rider - not fast by no means but faster than walking...

    That's why it's tricky to watch "segmented video" and try to make a judgement call on it - ALL segments could be manipulated with the guy just getting done coasting down a descent,,,

    here's a video clip that I believe is real - and one that even if the chair is on an angle and his weight slightly unbalanced it is actually a fair testing ground to at least prove propulsion due to it being 360 degree's so all imperfections are equalized - another words if he gained at the 90 degree mark he has to pay the fiddler at the 270 mark, and what kind of bearing in the chair? most likely just plain bearing nothing fancy...

    https://youtu.be/ApsnacMLoUs

    I also believe this vid to be for real - and it's piss poor quality but his testing is at least somewhat uniform as he goes back and forth on the same road so as far as cheating with downhill effect that's at least eliminated --- and he does pedal out of the turns to get up to a little speed - you would have to as like I said it's such a low torque machine that it would take many minutes to equalize it's effect with the drag factors,, but what's interesting is look how well it maintains the speed after the fact - and this looks to be a mountain bike with knobby tires?

    Bottom line is I do not believe the umbrella man would have to have had an electric skateboard to pull off his "illusion" like I stated before a skateboard had to be used as there would be no way he could have controlled a mop bucket with swivel castors...
    and the very lame propulsion would have ever so slightly helped with the illusion esp. in segments where you know there's level ground like at the gas pumps... don't forget vids can be mildly sped up to show no decrease in perceivable speed as well...

    There's one guy that knows for sure which tricks he was using - well make that two as he did have to get someone to video him... and yeah that being said - could indeed just be an electric skateboard too...

    My reactions, in order:

    Wow, that's fantastic. He must have hit a sweet spot between the leaf blower and the umbrella.

    But those wheels are awful small. How does that work.

    And how can he be steering by tilting when the bucket shown at the start had standard mop-bucket wheels at the corners.

    Boy, he sure is going fast for what it is.

    Oh, the wheels are different.

    You mean you can get an electric skate board? I never saw them before. Yea, that does look like a skate board under the bucket.

    And what's that black thing on tip of the leaf blower?

    So it is a hoax.

    Just don't ask me to make that umbrella.
