Believe it or not - I once tried it with my experimental prototype. As soon as I touched the handlebars with only a fingertip, the bike began to shake uncontrollably. I think I am stuck to my non-handlebar solution until the end ...
Similar problem with the trike I have build: My wife and daughter could ride it instantly but I never managed it, because the usual lean-steering does not work on the trike.
Happy to say that I finally have overcome my knee problems, so that I can ride my P3 again almost every day. And I still love it ...

Yes indeed!...only a question of time.....till Jürgen put also handlebars on his bike ;-) ;-) ;-)Serge from Belgium Dirk Bonné a écrit :Glad to hear it! I can't find any good picture of the handlebars but you can see a glimpse of them in this video right at the beginning: http://www.youtube.com/watch?v=0NRXeL89TwA These handlebars on my pythoon are 55cms wide. They are unnecesary wide, but are a consequence of trying to ride with a pivot angle of 70 and 80 degrees (now I am back at 60degrees which seems to be an optimum). On the baby python the handlebars were only 45cm wide. The handlebars are specifically NOT for excerting high force - and thus are not for turning. They just give the last measure of fine control that are not possible by foot-steer only. They especially help at low speed, at high speed, or in climbing situations. Practically all the pythoneers that can obtain high speeds (60+kmh) have handlebars installed. Dirk On 25.06.2010 13:43, Howard Stevens wrote:Hi again Dirk. Thanks for the suggestion....it works really well! I made a straight bar 430mm long and bolted it on top and 40mm in front of the main pivot joint. It feels comfortable, as it gives a convenient support for the hands and has virtually stopped the PSI. I think mounting it fore or aft of the joint probably doesn't affect the mechanical leverage, as the important leverage distance appears to be how far lateral to the pivot, the handgrips are placed. THe handlebarsare very little use for turning but great to stabilise the trike. Also I was previously worried about crashing if my feet slipped fromthe pedals, but this gives another means of control. So look out! I'm now cruising!! Cheers Howard
