Re: You got that backwards, we're trying to prove something is true. I can't but I'd like someone to show how it can be done. Kinda like Archimedes... edit:spelling

Re: Re: No, that would be fairly straightforward IMO.

Re: For you to suggest that I'm not a highly paid top engineer myself is naive. Period. Your memory fails you. Go back a few hundred posts and read what I think about possibilities regarding motor fraud. If I was a professional cyclist I would probably be cheating with motors...

Re: Re: I think I have asked you nicely seven times now to show how you would generate the torque, configure the gearbox, handle the temperature, interact with the freewheeling cassette, avoid public breakdown, etc etc, all within a non-conspicuous road hub. You keep doing a volumetric scaling...

Re: The winner of Paris-Roubaix 2017 was under scrutiny. Some argued a hub motor, I saw a Shimano hub and said 'no way'. IMO, one can only argue hub motor if the hub is BIG.

Re: See, I asked you to not do a 5 minute google search to find a generic product you could 'scale' to a road hub... Since you seem to agree that there must be a gearbox, you do realize that the "output shaft" (the axle that meets the dropouts) must exit the stator (the hub shell) on both...

Re: Re: I tried. Call it a failed effort to show that it can be done. I tried but couldn't. I then urged you to try. Please do. So far, I'm the only (?) one here that has done some real engineering using actual dimensions and adressing the packaging restraints. If you claim that it can be...

WTF? A skateboard hub motor doesn't need a gearbox, can be ~5 times bigger and there are four (4) hubs available. Please, don't ever use a skateboard as reference for a road bike, road hub motor...

Re: The thing is, John has not shown that he can produce even a conceptual design of a hub motor that fits in a road hub. Start here http://forum.cyclingnews.com/viewtopic.php?p=2062155#p2062155 and notice his constantly moving goal posts...

Re: ToreBear has geneterated a lot of anger in the XC-skiing thread, using the same kind of "alternative reasoning". He got no support from anyone about anything when trying to defend the norwegian dominance in the most VO2max-driven sport during the EPO era :rolleyes: When the top two XC...

I like this verdict. This is why: 1. Johaug is caught with stereoids in her blood. 2. She is asked to explain how that could happen 3. A completely improbable chain of events is fabricated. Funny thing is that it was the least improbable story that could be fabricated. 4. A very experienced...

I know, "hard to say" But in relation to the 'skin temperatured skin', they both seem a lot cooler, no?

Re: Re: The rolling resistance of the rear tire is ~15W. The drive train friction is ~9W. Assume 2/3 of that friction is generated at the cassette (lots of bending + high load), ~6W. The surface area of the tire is much greater and more exposed to the wind than the cassette, but of course it's...
