Bike For Speed

top speed : 200 km/h acceleration : from 0 to 100 in 4 hours

Great and fun project, but reading the comments, I don't think people really realize how hard it would be to be cycling on that bike! 😂

You deliver the maximum torque to the wheels when your crank arm is at an angle of 90° wrt to applied downward force (i.e. when it's horizontal to the ground), and 0 torque when crank arm makes 0° angle (when pedal is at it's lowest and highest positions), hence the relationship between crank arm angle and Force is "T = F*Sin(θ)" where T is Torque, F is applied downward force, θ is Crank Arm angle.. now the wider the diameter of the crank set, the more Force you need to apply, since T = F*sin(θ) increasing F, increases the amplitude of the sin wave very sharply, hence when θ= 90°, you'd need to put A TON of force in order to even move forward.. hence this thing can only be used on horizontal ground, if there's any slope, you're dead. Thanks for reading have a nice day.

I can't imagine how difficult it is to even get the bike moving with that sprocket configuration! Great video!

Let just appreciate how much this man spends on bikes in a year

The fun part is that he built a bike to reach high speeds that does not have brakes!

"This seems like a fun channel" "Buy our NFT" "Nevermind..."

Reminds me of how I used to do speed training throughout the entire summer during its holidays. Almost every day, from morning until evening, I would try to ride as fast as I could. My bicycle wasn't really expensive and cool; it was just quite light and had 3*7 speed modes (I don't know how it's called in English). So, by the end of the summer, I was riding on a straight road and gradually began to catch up with a scooter. A little time after I overtook it and realized that I was faster than the scooter. I was in total shock. Well, the guy who was riding the scooter also looked at me like, 'What on earth is this?!' Of course, it was a low-power engine scooter, but it's still one of my highlights.

This man has done what my intrusive thoughts have wanted me to do for years. Truly one of the chainrings of all time

That gear ratio will take you to much higher speeds than in the video, if you have the legs to push such a large gear. Wind resistance will quickly be a limiting factor. 53*11, which is a pretty common gear to have, yields over 70kph at 120rpm with a road bike wheel size (700c).

Love your skill and effort to transform normal bike to a super fast one 😮😮😮

I used to cycle everywhere and had extremely strong legs. I was on the lookout for a bike like this, because the gear ratio on my bikes didn’t challenge me even in the fastest gears. Unlike my friends who were into high reps to maintain speed, I liked to use the fastest gear and pedal less revolutions, taking advantage of my strength. I never was able to find anything like this back then. Wish I had, though maybe not quite as extreme.

Riding 60 km/h on a bike without brakes 🙈😧. Nice build, as usual!😎

As a cycle guy who comes out of home at 9:05 and wants to reach destination by 9:00, I want to say that this is a very nice invention.

Damn, I know I'm a year late to this party, but I started this video out super excited, it was a fun concept, you opened it on a bike with a gorgeous frame with some real hipster commuter potential and then you announced an NFT project. It's too bad I didn't get past the first forty seconds, I bet the rest was cool.

This is a man of focus, dedication and sheer effon will

you could've gained the same effect by going to a small sprocket connect to a larger sprocket on an independent axle in the middle of swingarm before going to the rear axle. That would've saved weight, be stronger, and far easier to produce. However, the bike wouldn't be as eye catching at first glance.

This guy is almost too bored, imagine if he creates a quad bicycle, seriously this guy is innovative and also very crafty!

Если уменьшить лобовое сопротивление, то можно добавить ещё 5-10 км/ч, и при столкновении поймать ещё больше переломов. Снимите видео как на таком велосипеде ехать хоть в небольшой подъём.

One chain RING that binds them all... Finally this guy cracked it
