i thought it was a pump at first now i realise its just a right angled drive for belts

 

[PP Bear]

Won’t play for me unfortunately

An elaborate method for belts to turn a corner.

His lubricant looks very emulsified.

Wonder what the efficiency is versus gears?

 

[Jim]

So clever

I think it must just be an exhibition piece, can't see it standing up to much hard work/torque used by the belt size of those pulleys?

 

[TinaLes]

Wow! Great example of KISS.

Gears would seem to be a more practical solution. It would be interesting to see how much vibration there is when it's running.

Exactly! It makes one wonder why it only shows 4 very slow revolutions and not a belt in sight?

 

[tacr2man]

probably OK at low speed , the various directional changes not good for high speed ?

Can’t remember exact number but you lost either 20% or 25% power at the back wheel running a shaft drive bike versus a chain drive. This isn’t theoretical it was proven converting shaft drive to chain.

There would be losses on the setup in the video but no idea how it compares to crown and pinion. Saying that it would be relatively low powered drive system anyway I would expect
