THE WORLD'S SIMPLEST TRANSMISSION for BICYCLE

[TheGr8scott]

Absolutely useless and it defeats the purpose.

[htomerif]

this is incredibly useful. Now we can teach students in physics, engineering, math and design what not to do in one simple video.

[LucaBoulders]

I like that

[howsey182]

go faster change down a gear lol

[harpbloke]

hi, in your video you are using the resistance of the chain to make the ratio change possible, so, whilst riding, do you have to change the pedals at different times?

or do have you set up the hub gears to not free wheel?

[rich1051414]

@TABAGfrancis please ignore the 12 year old kids laughing at tabag, since in english, its similar to teabag. Teabagging is slang for crouching and standing over and over above the head of a person they just killed in a shooting game to get a laugh. This is done to someone no one likes for whatever reasons, or randomly by very immature players.

[JungalistJoe]

@rich1051414 It's when you dunk your balls in someones mouth repeatedly, using the same motion you would dunk a teabag in a cup of tea.

Stop playing video games and experience life, your missing out on the good stuff.

[rich1051414]

@JungalistJoe lol i know what it really means, the real meaning i assumed was implied, and no, i knew the word before it became video game lingo, but unfortunately alot of youtubers are gamers and is why they are getting a kick out of your name. I am not part of that crowd, and was informing you so you would not be offended.

[tld5500]

I am interested. What have you done about the hub on the wheel? I am dreaming of ways to make a CVT, by changing the radius of the crankshaft, then move the fulcrum, or pivot point of levers attached to push rods.

[ieres100]

wath the fuck

[OdysseyBMX98]

LMAO I THOUGHT tht said Tebag

[PersonalRaineri]

These inventions are cracking me up. Maybe you could next invent a bicycle driven by muscle power and your trademark gear system. That would be the most super efficient shit ever!

[chaosopher23]

Keep the crank as long as possible, and use a standard derailleur system on the sprockets. While not as simple, the legs like a long stroke, even if it takes a bit of effort in the high gears. Longer strokes mean more time propelling the bicycle, and they're easier, too.

TeABAG

[chrisbear08]

TeaBag? Ohh TABAG...

[Jthetinman]

What the fuckin fuck?

[elvensbane]

TABAG. ROFL.

[SuperJerico23]

are you Filipino?

[dchaffee02]

@ the un-experienced, self-proclaimed experts - Forget about your precious cadence, linear travel of your feet is the real issue. You might pedal your roadie at 70 strokes/minute but try pedaling longer cranks at that cadence and see how long you last. If the pedals shown were moved from a radius of 180mm to 165mm your feet would have to travel a 9% less distance. That's the same effect as shifting from a 46 tooth chainring to a 50 tooth chainring. My 2 cents worth.

[tapjahunt]

@dchaffee02 it`s **** to ride

[superdope72]

@dchaffee02 so is it good or bad?

[dchaffee02]

@superdope72 I say its a good idea as long as the pedals don't shift accidentally. However in order to make it useful @ the longer radius you will sacrifice your leg extension when shifting to the shorter radius. But hell, the ones who complain about that are the racing elitists who blow >$150 to have their rides fitted to that "optimal" geometry. Then heaven help them if they slide their pea-sized lilly-lycra'd nads 2mm any either direction the whole time they're stroking. Damned elitists.

[heli400]

@dchaffee02 (You posted a year ago).... You claim reducing the size of the crank from 180mm to 165mm resulting in a 9% less distance traveled.... what does linear distance traveled have to do with applying force? The force produced on a bike crank is perpendicular to the radius from the center of the circle. (think - teetter totter.) Which requires more force? a force applied at 165mm or 180mm from the fulcrum? Yes more linear distance is traveled at 180mm but less force required to do so.

[dchaffee02]

@heli400 Its the classic speed vs distance trade-off that levers allow you to achieve. Using your teeter totter example, by sitting closer to the fulcrum you can apply about the same amount of force to lift the other person the same distance as before but you move a shorter distance at lower speed or you can try to keep your speed the same which costs more force but you've sped up the person on the other end. Gears are just funny shaped levers that allow you to trade distance for speed.

[Joppewo]

This isn't a transmission, you still have the same cadence for same power, whereas transmission makes you need more or less power at same cadence. All this does is make more force needed but the force needs to be applied for a shorter distance since the crankarm is shorter. Useless "gear" :D

[LoserSVK]

@Joppewo It is some kind of transmission but useless because of anatomy of human. Those ideas really sux and cant imagine why someone wasted his time for this if you can see that this will never work on first look.

[juanavilarios]

Wtf haha science and technology wat a dumb ass haha

[martinpageau1]

noob your video are so bad and long :(

[IsaacBickerstaffEsq]

Give me a lever arm short enough and I can fail to move the world.

[FilippoGatti1991]

@IsaacBickerstaffEsq lol

[TABAGfrancis]

For the idea watch: UNIQUE BIKE CRANK ( 2- SPEED)

............. Engr. TABAG ( Inventor)

[s38a5t13n]

this is actually kinda cool

[timbobel]

keep it simple. youre making it complicated.

[VarykGerai]

@TABAGfrancis how exactly does that work? shorter arm = closer to pivot point = more force is needed on the arm so that the force transmited to the gear on the wheel would remain the same. size of gears adds/removes speed not the length of the arm. Trying to invent a bicycle?
