Hi Vi, Hi Dirk, I can imagine there being a need for this basic principle, but in reverse. Riders with some back problems may need some help _getting down_ instead of getting up, which is the problem resolved by the system in the link. Since with the lowrider the weight has to be borne during the lifting/lowering (which is not the case with the linked system, the degree of complexity and the engineering for reliability issues are considerably higher. Cf., some of the variable height solutions // to the development of the Air-Bike. Wondering what Jürgen thinks about this.

Hi Vi, why would you need this on a lowracer? the design introduces 4 joints/axes that are prone to play. I reckon, that the seat will give you a wobbly feeling one day... interchangeable seat mountings are a good thing on recumbents, in case of different sized riders - DirkS Vi Vuong<vi_vuong@xxxxxxxxx> hat am 25.

It seems that we shouldrecommend beginners to start out with high seat, and then lower as they progress or want more challenge. How about an adjustable seat height design, anyone?Cheers, Vihttp://dirk.steuwer.de ============================================================ This is the Python Mailinglist //www.freelists.org/list/python Listmaster: Jurgen Mages jmages@xxxxxx To unsubscribe send an empty mail to python-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field. ============================================================ ----- No virus found in this message.
