This man wasn’t satisfied with how fast his bike could go… so he modified it in an extreme way! He added an extra gear by welding a new axle—creating a crazy transmission system where one pedal stroke spins the rear wheel multiple times. The result? This bike can go as fast as a moped!

  1. Wow
    Wow
    As fast as a
    MOPED!!
    Is that downhill?!
    Silly , as are so many of this variety of goofy vids.
    Don't tell me he quit his job in aerospace because someone there was stealing his idea , but he wanted humanity to have access to this amazingtechnology?

  2. FRONT SPROCKET 56 TEETH , REAR FREEWHEEL 13 TEETH, IF I RECALL 4.5 TO 1 RATIO = MAKES SIMPLY ONE ROTATION OF PEDAL TURNING REAR WHEEL FOUR AND HALF TIMES. IF I RECALL THAT WAS TWENTY- SIX FEET , ON A BMX BIKE MADE INTO A TEN SPEED. ALL WAS NEEDED WAS SHIMING FRONT CRANK TO PREVENT SPROCKET HITTING BIKE FRAME AND PHYSICALLY SPREADING REAR WHEEL FRAME SO TIRE WILL FIT . MAYBE SHIM FOR SPROCKETS ALIGNMENT, ETC. NO PROBLEM FOR FRONT CRANK TO HAVE TWO SPROCKETS. AND FIVE FOR FREEWHEEL. I HAVEN'T SEEN A " 56" SINCE THE 80'S,BUT I KNOW THAT THEY ARE OUT THERE, BUT DUDE ! YOU'LL MAKE "TENSPEEDS" LOOK LIKE THIER STANDING STILL! AND YOU BETTER HAVE DAM GOOOD BRAKES. I S#!^T YOU NOT! YOUR NUTS, BOLTS, AND BALLS, SCREAMING 😱 MOMMMY!😂 YOU MAY NEED LONGER CHAIN IF I RECALL. 😊
    FREEWHEEL AND TENSPEEDS INTERCHANGE BACK IN THE 80'S.

  3. A 3-speed hub, combined with a 3×9 derailleur system has been on the market since 35 years, so this is nothing new.
    But I wonder, how strong are his legs, because someone like Harrie Lavreysen is capable of speeds of up to 80 km/h on his bike.

    Harrie uses a 69×15 gear ratio, but he can do that because he can generate around 800 kg of pedal force.

    With a peak power output of around 2,600 watts, Lavreysen produces a power output almost double that of road sprinters.

  4. Most road bikes can be pedaled at 40+ mph! Good look doing it on a flat road, though! It takes approximately 600w to do 40 mph on flat road with no wind! Even world tour pro cyclists can only do 600w for about 5 minutes maximum! The average cyclist can do 600w for 30-60 SECONDS! The guy in the video, on flat pedals, could probably do 600w for 10 seconds! Enough to get that bike UPTO around 25 mph… for 10 seconds!
