Talk:Stoppie

Motorcycling also?

Isn't there a motorcylists version of this trick?--Knife Knut 01:08, 8 Jun 2005 (UTC)

Endo

This article seems to claims that the stoppie and the endo are the same, while endo (cycling) says they are different, but doesn't say how. Pissant 00:08, 20 February 2006 (UTC)

i always thought that an endo was the rider bailing over the handlebars, while the stoppie was riding the front wheel.Motorbyclist 10:03, 15 February 2007 (UTC)

Same here. I've always been under the impression that a Endo was a "failed" stoppie where you flip your bike end-over-end thus the name 'End-o.' Maybe we need a citation needed for this? RaggTopp (talk) 12:55, 9 September 2012 (UTC)

It would definitely be good to get some clarity on the difference, if there is any, and some etymology of known. jezmck (talk) 19:30, 5 October 2021 (UTC)

Consistency Problem: Rear Brake

The article states that the rear brake is not used, which appears to conflict with the graph's indication that it is used. DavidGC 10:52, 12 May 2006 (UTC)

The graph clearly shows the rear brake being applied only at the end of the maneuver. It is not necessary. -AndrewDressel (talk) 15:24, 27 February 2009 (UTC)

Applying the rear brake when the wheel is spinning would contribute to the forward pitching moment. I'm not sure if it's significant. It could also be a reflex action from the rider. --90.231.35.118 (talk) 19:02, 4 October 2009 (UTC)

Image and graph

In the image the motorbike is facing in the opposite direction to the sequence in the stills. Someone who can manipulate images needs to reverse this part of the image so that just as the sequence goes left to right, the bike appears to travel that way. Lumos3 11:54, 6 June 2006 (UTC)

Managed to do this myself. Lumos3 12:28, 6 June 2006 (UTC)

that graph is a mess, and the images, while effective could be of higher qualityMotorbyclist 10:04, 15 February 2007 (UTC)

The graph looks like an elementary school art project. It should be removed, and the entire article needs cleaning up. Exploding Boy 17:02, 5 May 2007 (UTC)

Friction

The description of friction is incorrect. Friction does *not* increase as you put more weight on the front tire. I'm updating this section along with a reference to http://www.msgroup.org/forums/mtt/topic.asp?TOPIC_ID=4533.

The entire topic of friction appears to have been removed, along with the bogus forum reference. -AndrewDressel (talk) 15:25, 27 February 2009 (UTC)

Safety warning

I feel very strongly that the warning of the unsafe nature of an Endo has no place here. This encyclopaedia covers a raft of risky activities, be they rock climbing and mountaineering, cycling, or whatever, and cannot comment authoritatively on the safety of them all. Further, there is a serious risk of liability if we create a perception that dangerous activities are listed as such. Any dangerous activity not so listed could then open WP up to legal action. In short, we should not presume to advise anybody on what they should or should not be doing. Article edited accordingly. --Che Gannarelli (talk) 23:14, 6 September 2008 (UTC)

G forces and de-acceleration

Is there any calculations of the G forces and de-acceleration? My own roughly calculations for about 10-15 years back came to a conclusion that the force/de-acceleration is something like 2-3G for a bike. I think that a motorcycle gives more G:s because of its weight. Can this be verified with reliable source? --Kslotte (talk) 14:45, 21 September 2009 (UTC)

According to Bicycle_and_motorcycle_dynamics#Braking :

For an upright bicycle on dry asphalt with excellent brakes, pitching will probably be the limiting factor. The combined center of mass of a typical upright bicycle and rider will be about 60 cm (23.6 in) back from the front wheel contact patch and 120 cm (47.2 in) above, allowing a maximum deceleration of 0.5 g (4.9 m/s² or 16 ft/s²).[10] If the rider modulates the brakes properly, however, pitching can be avoided. If the rider moves his weight back and down, even larger decelerations are possible.

The last sentence is interesting. For example with mountain bikes the rider moves his weight back and down when breaking. But with a motorcycle the rider can only move back, not down. --Kslotte (talk) 14:59, 21 September 2009 (UTC)

Ridiculous

This has to be the most stupid thing you can do on a motorcycle. — Preceding unsigned comment added by 67.142.130.46 (talk) 03:27, 24 August 2011 (UTC)
