Insane Chainless Bicycle Prototype

Imagine bicycle without chain. Can it work as well as regular one? Well.. let's watch this cool experiment and find out.
Yes, this prototype works but definitely needs some modifications.

Congratulations on the rediscovery of ancient bicycle technology.

This man took "We are evolving, just backwards" to next level

I've seen this idea before. Problems are 1) gear ratio, you're confined to one, 2) the actual contact point and transmission of power is confined to a single tooth at a time thereby putting extreme force onto a small point, 3) the drive shaft roller bearings are pretty small and likely to fail quickly, 4) the drive shaft is thin and subject to distortion.

Finally! They've made a bike that you have to pedal twice as much to go half as far!

[terrificfrogg]

Pretty cool but it actually shows how efficient the chain mechanism is

I love how this “prototype” has been around since the late 1800’s

The Q: Rides a bicycle.
The bicycle: My time has come.

This reminds me of those ideas I had when I was a kid and how genius it was. Only to discover someone already made it years ago. This gives me same vibe.

This's cool DIY video, but shaft-driven bicycles are already there for more than 100 years, since 1890.
Actually, chain-driven are considered a vast improvement over shaft-driven bicycles with better performance, efficiency, and ease of maintenance.

The sleek look is definitely top notch. The major disadvantage is friction loss which will be much higher than a conventional chain.

Nothing like re-inventing the wheel. A pal of mine has an 1898 Belgian FN, which I've ridden. Nothing new here, but I admire your hack it and weld outlook.

'The Q' in 2030 : "Tireless Bicycle prototype"

[pradeeppanchal]

You can't Stop paddle when it's move freely, I mean there a very important role of one way bearing which is missing in this case

[Trutko.Dmitry]

Такие системы были опробованы ранее. Очень много недостатков.
1. Слишком большой вес.
2. Быстрый износ зубчатых колёс.
3. Необходимо дополнииельно создать систему свободного хода.
4. Ухудшение регулировки колёс. Плюс десяток других недостатков.

This was invented 100 years ago. One was found in a barn on American Pickers.

[darthvail]

The major issue with his sprocket build is that he was to pedal extremely fast for minimal energy transfer. In other words his system is far less effective than a traditional chain gear system

[jareddahlseid]

Looks like perfect gearing for those who had to ride to school uphill both ways!

[retweaksatapathy]

The gear ratio being the same for peddal and wheel would require lot more peddling to travel the same distance but this idea was awesome.

[oczhaal]

the chainless bike was used during WWI by the belgian army. The bicycle was made by FN Herstal and it had so many flaws and was so hard to pedal when the road wasn't flat, that it was quickly abandoned.

People can say what they want about efficiency vs chain drive but you can't deny the craftsmanship. Great video
