Sherer USA TLT Torque lever recumbent trike
The design doesn't really appear to be all that revolutionary. The
levers pull cables or rods that in turn rotate a sprocket for the chain drive. The only apparent advantage is the longer arms on the levers than you can normally get in a crank set. That could be enough to provide improved results such as higher speed and/or less effort for similar results. I too am looking forward to seeing the video. Just a side note, often better designs are ignored in favor of poorer ones due to better marketing (for example, beta versus vhs format for videos) or sheer momentum of the existing marketplace that wouldn't want to retool to incorporate the better design (for example, more fuel efficient or alternative fuel automobiles). So rather than shoot this down, I'll be interested to see the video. I may even buy one if the video is compelling enough. --Russ Jeff Grippe wrote: I forgot all about Johnny.

I agree with what you've said. I like to keep an open mind. I'd love to see
something that could go up hill at the kind of speeds that he's claiming. The good news with this trike is that the only part that would need to be replaced to turn it into a conventional trike would be the front boom (along with chain rings, etc.). It is mostly a standard Tom Teesdale trike frame which is built to Greenspeed specs. Jeff "Rusty Bucket Bent Triker" wrote in message ups.com...

You would be WAY outside of optimum power posture. I hope Teesdale collected his costs up front for the fabrications of this monstrosity. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

The front tube angles down from the cross tubes, so that if you replaced the boom parts, the bottom bracket would be too low for crank arms and clearence or your heels.

It's not revolutionary, not by a long shot. Lever drives have been
tried over and over again since the '70's... the *18*70's. None have come close to equalling the performance of conventional rotary cranks, the claims on the website notwithstanding. If lever or linear drive provided some advantage, you'd expect HPV racers (who have no rules regarding drive systems) to be using them. As far as I've seen, *all* of the fastest human-powered vehicles use conventional rotary cranks, even when this means compromising the design of the vehicle to accomodate the cranks.

I think you are probably right. I'm not rushing out to buy one. I am still
curious to see the video and if I lived close enough to test ride one, I would. I also find it impossible to believe that there is a mechanical technology available that is so much better (or even better at all) than what we are using. If the system had two cables per pedal to take advantage of both the concentric and eccentric muscle movements then I might think he was on to something. I know that pedals and clips are supposed to give you the ability to work in all directions but I've never been good at doing it. A lever system that forced you to work in both directions could produce greater speed but that greater speed would come with greater effort. The claim on this web site is greater speed with the same effort. It seems to defy the laws of physics. Jeff "Jeff Wills" wrote in message ups.com... It's not revolutionary, not by a long shot.

"Jeff Grippe" jeff@door7 wrote in message ... == snip == The claim on this web site is greater speed with the same effort. It seems to defy the laws of physics. Jeff I think you nailed it here, Jeff. Whether you use levers or cranks to transfer power from man to machine shouldn't make much difference in the long run. It still would take the same amount of power to move the machine at a given speed. If a person could move this thing 40 MPH steadily, on the flat, with levers, he could probably do it with cranks, too. However, since the levers operate independently, it is possible to push both at the same time. It might be possible to get up to 25 or 30 MPH pushing the levers alternately, then give one or two humungous heaves with both legs at once and hit a 40 MPH peak. That is if the back wheel doesn't lose traction and you don't punch through the seat into the back tire. But to keep this up steadily--I don't think so. Maybe Lance.... ;-) Jerry |

"Scottie, I need WARP power in three minutes or we're dead." %^) I think you nailed it here, Jeff. Whether you use levers or cranks to transfer power from man to machine shouldn't make much difference in the long run. If the drive train were more efficient (less losses) or the human power input interface (levers, cranks) were more efficient (more ergonomic, recruiting more muscles, less losses), then the laws of physics could be obeyed and one design might be faster than another. As others have suggested, if a human power input interface equal or better than cranks were developed (and many have tried), it would likely appear in the fully faired 80+ mph HPV racers where dealing with crank and foot clearance seems to be one of the limiting factors for more aerodynamic enclosures.

They have put a video of the trike on the web site although you can't see
much more than you can with the static picture. It looks like it has a lot of pedal steer. Other opinions? http://www.shererusa.com/page5.html "Jeff Grippe" jeff@door7 wrote in message ...
