in my 21 years of life i have finally researched why the fuck bikes are only able to go forward, however that only planted a new question in my mind.

Why the fuck are bikes set up so that they go forward? i understand the mechanism, but i just dont understand what advantage that gets to direct link between the pedals and the wheel.

you'd understand if you ever had your shoelaces tangled on a fixed speed bike's pedals

So you don't understand basic mechanics and gearing until someone explains it to you as an adult. And as an adult you still don't understand why bikes aren't made with reverse gearing, but you have the audacity to call someone else retarded?

On a related topic, why do bikes have round tires?

How can I cook a frozen burrito if my mom dosen't do it for me?

And why is op a homosexual?

Move to Logan Square and start riding a fixie. After the first crash, you will understand why freewheels are a thing.

you dont get it nigger. If you could read you would understand that i stated that i knew how the mechanism works. I just dont know WHY they picked that mechanism instead of going for a direct ratio.

i've rode and crashed bikes several times, never had shoelaces stuck on them and never reallly understood it.

Lel I used to vote Dem and all that shit and hate the Republicans. But after I moved away from IL and 10% sales tax and came to FL with no state income tax, I started to hate the Democrats. I realized that it's possible to pay less in taxes and still have roads and schools and firefighters and that all of these Liberal quick fix programs of "tax the hard working middle class and give to those who just don't feel like working or learning a skill" just completely fuck up everything.

It's not just about the shoelaces. If you aren't 100% confident on the fixie bikes, it's real easy to fuck your shit up. First time I rode one and realized you had to keep pedaling while trying to turn, it almost rekt me.

>why they picked that mechanism
Are you talking about the roughly 3:1 drive ratio or the freewheel design where you don't have to pedal all the time?

Because the ~3:1 ratio (on my BMX it's a 30T chainwheel and 10T on the hub so every 1 time I pedal, the rear wheel spins 3 times) is for the speed. If it were 1:1, it would be like a super low gear and would be about as fast as walking.

But the freewheel, you just need to ride a fixed gear. It uses up a lot more energy because your legs are always moving. You can't just coast downhill. Kinda destroys the benefits of the bicycle being an efficient mode of transportation.

Look into "Freecoasters". It's a type of hub made for BMX bicycles where you can be coasting in reverse and the pedals won't move backwards. They are more complicated than the typical freewheel but they could probably design something along those lines that allows you to pedal the bicycle backwards.

Here's a good video about freecoasters. From the finest scientists and engineers in the BMX industry!

https://youtu.be/04O9q8-kRx4

He mentions the slack, that is the one annoying thing about that hub design. When you go to pedal, you have to move the cranks like 1/4 rotation before it starts to bite. You can normally adjust them and make the slack much less so it feels really close to a regular freewheel or casette, but then when you are going in reverse you have to keep your feet perfectly still or else it will catch and start spinning the cranks like a regular freewheel instead of coasting.

Basically you need to ride all of these- freecoaster, freewheel, and fixie- before you really know the advantages and disadvantages.

That...... Explains a lot. More friction in one way but less friction in the other.

pretty sure fixies go both ways, just like the faggots who ride them

Idk if it's about friction, but moreso that your legs actually have a chance to rest and you can coast on a regular bike and your legs never stop moving on a fixie.
