Talk:Bicycle and motorcycle dynamics

message: I'm a bit astonished to see no reference to Robin Sharp's work on motorcycle dynamics? I mean in the text itself - in the history section it reads as if the 2007 work was the first time the equations of motion have been written down. Black bird blue (talk) 13:54, 5 December 2008 (UTC)
replies: text: The history doesn't mention Cossalter, either. If you think it should, please just add it without all the hysterics. 2007 was the first time the equations have been written down with a comprehensive literature review and verification by other means. At least that's what the reference says. If you think we've done a bad job, you can always just cut our budget. -AndrewDressel (talk) 15:29, 5 December 2008 (UTC)
replies: text: Sharp is added. Cossalter can add himself, his work isn't widely regarded as credible although his pictures are pretty. 88.108.190.85 (talk) 00:06, 6 December 2008 (UTC)
thread_title:  History 

message: Article has these two statements:
1. At normal bicycling speeds on level ground, aerodynamic drag is the largest force resisting forward motion.
2. At faster speed, aerodynamic drag becomes overwhelmingly the largest force resisting forward motion.
One of the references to "aerodynamic drag" must be wrong.

message: In the main article in the section Longitudinal Dynamics the picture caption reads "a rider performing a wheelie", this is incorrect, the picture clearly shows a BMX rider performing a manual.  A wheelie and a manual are not the same thing, the mode of balancing is different between the two, the former is reliant upon torque/brake whilst the latter is solely reliant upon balance, achieved by moving the centre of gravity (the riders body) forwards and backwards.  The difference is such that a rider who can perform a wheelie may not be able to manual, and vice versa.  Please fix! 80.229.162.156 (talk) 00:05, 30 December 2016 (UTC)

message: In the Real Wheel Steering section the article mentions the, as yet unclaimed prize (offered by Rainbow Trainers), for successfully riding a bicycle with rear wheel steering.  However, there are endless clips on YouTube showing people riding conventional bikes backwards.  As this is evidently possible then surely riding a "rear wheel steered" bike is similarly equally possible?!  Sorry, this is more of an observation on this (interesting) section than a request for an edit, but just a point for consideration! 80.229.162.156 (talk) 00:17, 30 December 2016 (UTC)

message: This recent addition:
:"A technique used on poor surfaces is to alternately (and gently) pump front and back brakes so that if they start to break away they can rapidly regain traction while the other wheel continues to contribute a stopping force, this technique also reduces brake heating, reducing brake fade."
has several issues:
:#Wikipedia is not a how-to manual
:#The cited "source" is "Relja, a quite decent bicycle mechanic" on what appears to be his personal blog.
