    Nice idea but just wait until Peter Sagan’s legs start pumping his end of stage sprinting HP through that rear cog ….. ping!

    Have it tested out by PeterSagan at 60 km /hr



  3. mistral55 on July 27, 2019 at 11:24 pm

    Mud? sand?…



  4. Andrew Montague on July 27, 2019 at 11:24 pm

    I want some that and hate sore legs by hills

    Like any concept vehicle it is not a fully working model but the principal could be developed. Unfortunately there is a reason most motorcycles don’t use shaft drive. Changing the rotational direction and being able to handle the torque introduces lots of friction.

    china will nik your idea



  7. Sam Chiu on July 27, 2019 at 11:26 pm

    Use a solid rear cog then the drive shaft can have a continuous range of movement.



  8. Ghanshyam Singh on July 27, 2019 at 11:26 pm

    Brilliant design….. when it would be available in India and how much it would be?



  9. Matchless AJS BSA on July 27, 2019 at 11:27 pm

    You said you could change the overall gearing by swapping the drive shaft. If you just swapped the shaft with different sized ‘gears’ on each end the ‘gears’ wouldn’t mesh properly. If the shaft gear was smaller there’d be more backlash and if it was larger you wouldn’t be able to assemble it at all. You would have to reset the shaft mounts to get things to line up and mesh properly.

    To Frail to Derail. only good if you rode in a clean room. add dirt, snow or water and your walking home. but cool concept.



  11. Sjaak McD on July 27, 2019 at 11:28 pm

    should, could, will? So nothing built that works then!



  12. Gregory McCoy on July 27, 2019 at 11:29 pm

    Show us somebody riding it, that was all jibber until we see it actually move.

    Freaking brilliant



  15. John Doe on July 27, 2019 at 11:33 pm

    They need to encase it somehow so that road dirt, mud doesn’t get in there.



  16. jancreighton on July 27, 2019 at 11:34 pm

    lol – that prototype was designed by someone who knows absolutely nothing about the laws of physics. This is what happens when you get a wet-behind-the-ears university engineering graduate, (educated on autocad, who has never had oil on their hands, and who has probably never ridden a bike), to design something. There is a reason why they don’t show anyone riding this thing,  and why they never will – because as soon as you put power through those pedals, the entire contraption will explode into a heap of shards, and the "gears"-disk at the back will crumple like tin foil. A total fail.



  17. Keyboard Dancers on July 27, 2019 at 11:36 pm

    I see no gear changing.



  18. Victor Silva on July 27, 2019 at 11:37 pm

    You keep telling us how efficient this is compared to the classic chain derailleur system. So if this is 99% efficient how efficient is the classic derailleur system? I have a feeling it’s not too different. If the chain in a classic system is made with bearings it would have zero friction points.



  19. 1spiders1 on July 27, 2019 at 11:38 pm

    Only 10% lighter oh we don’t know not measured it lol



  20. Jacques Brun on July 27, 2019 at 11:41 pm

    Could you put this idea to a manual wheelchair?my email, jbrun1961@hotmail.com
    Thank you



  21. Pleroma on July 27, 2019 at 11:41 pm

    I need to see someone actually using this tech on the ROAD



  22. Scott Stewart on July 27, 2019 at 11:48 pm

    So many experts in the comments section.



  23. simone versaci on July 27, 2019 at 11:48 pm

    Cagata pazzesca!



  24. AG Coarseman on July 27, 2019 at 11:49 pm

    OK, I am sold….now how do I switch the gears?



  25. L45V3G45 on July 27, 2019 at 11:49 pm


  26. George Wade on July 27, 2019 at 11:50 pm

    so one year later (2019) can it switch gears yet hahahahha



  27. Joel Mayores on July 27, 2019 at 11:50 pm

    why don’t you just pedal it to see for ourselves how it works…



  28. Educated Manholecover on July 27, 2019 at 11:51 pm

    Crap. Waste of time watching this trash



  29. Kelvin Ham on July 27, 2019 at 11:51 pm

    The angle of load on the large gear loks problematic to me. I woould expect it to warp or buckle over time. Probably okay on the inner ring gear, but outer gear is under huge deflecting load.



  30. Martin Grindrod on July 27, 2019 at 11:55 pm

    So they didn’t even manage to weigh it? Plus easiest thing in the world to hook it up to a test bed and see what happens at different power levels, no test data, really??!! I’ll stick with my 3 speed hub thanks!!



  31. Alex de Melo on July 28, 2019 at 12:01 am

    I’d like to see it working.



  32. Biami21 on July 28, 2019 at 12:03 am

    Good concept

  34. Shawn Clark on July 28, 2019 at 12:09 am

    cool



  35. hobpeeper on July 28, 2019 at 12:10 am

    Is this something that would benefit slower, less powerful riders and not be enough for really strong cyclists? Sounds like a bit of a leveling technology to me.

    where cn i buy this …..????



  38. Proculopsis on July 28, 2019 at 12:11 am

    This is what’s called a "Spoof of Concept"



  39. originalscottfree on July 28, 2019 at 12:13 am

    Looks really neat, lots of possibilities… One issue, what would happen if you threw a hand full of wet mud on that rear sprocket? Asking for a friend.

    Fucking spinning wheel of death on the back of your bike



  41. 1spiders1 on July 28, 2019 at 12:15 am

    But what about torque and power ? So when you riding in high gear

  43. Matchless AJS BSA on July 28, 2019 at 12:16 am

    You estimated a weight saving of between 10 and 15%. Why didn’t you just weigh the kit and compare with a conventional setup before making the video, then you could give the actual figures instead of an estimate?



  44. Bill I on July 28, 2019 at 12:17 am

    show us shifting it must not work joke

  46. toxicat on July 28, 2019 at 12:17 am

    It certainly looks pretty….



  47. Kristijonas on July 28, 2019 at 12:18 am

    they are reinventing the gears , and useing batteries to switch gears, how much torque can this system hold without breaking, i doubt that traditional gears are not efficient, maybe just have planetary reductor instead then. Well made gears are mostly rolling anyway because of special teeth profiles. 😀 *sarcasm intensifies*. I am mechanical engineer, that is working on aerospace industry.

    What a fucktard

    The more you listen, the more you realize it does’nt work.
