Original – Updated diagram of a bicycle
Reason
Back in October, a version of this file – File:Bicycle diagram-en.svg, which is still the version used in articles – was nominated which attracted a lot of comment, which can be summarised as saying that the idea was fine but there were problems in the execution. Since then, I've implemented a raft of small changes. Some of them are identified on the file page. There were some suggestions of things to include, but I've concentrated on fixing the flaws in the implementation. After all, I think there's room in our article to have a fairly simple diagram alongside more complex ones. Very instructive in my opinion. (Will update articles if it passes; or maybe even if not.)
Changes include: greyscale the bicycle; change the circle markers to blue; reorganise to avoid annoying overlaps; remove grey boxes; split the seat area section; capitalise labels; redo wheels so that the spokes are radially equidistant.

  • Oppose I think the diagram can be improved a bit further (but feel free to debate my points):
  • The front may be better with a disc brake, firstly to illustrate different types of brakes used on bicycles, and secondly because the left part of the fork has clearly the mounting holes for a disc brake caliper. As it is now, the viewer is left confused as to why the left and right halves of the fork appear different.
  • The seat tube and seat post are not entirely straight even though they are straight in most frames.
  • The left crank and pedal are not shown even though it seems to me they ought to be partially seen at that angle.
  • Now that the colouring has been removed, the awkward pinkish hue that remains on the derailleur and sprocket components seems out of place (and suggests rust).
  • The lack of perspective on the handlebars is inconsistent with the perspective on the fork, the seat stay, and the chain stay. Maybe it would be better not to have perspective at all.
  • The shadows underneath the wheels are distracting and unnecessary -- it is obvious the wheels rest on the ground.
  • The blue pointers are not easily followed due to low contrast between blue and dark grey and due to the many intersecting spokes.
  • The shading and glossy reflections on the frame are inconsistent and have many glitches. It may be better to remove the shading altogether.
  • Is Front set a commonly accepted term or something made up for this diagram? I couldn't find the term either in Bicycle frame or in Bicycle. Besides, the head tube is usually considered to be part of the frame.
As a side note, perhaps a well-executed bicycle diagram clearly illustrating the different parts ought to be bigger and shown more prominently on the bicycle article. -- dllu (talk) 09:50, 3 March 2013 (UTC)[reply]
  • Weak Support It is much improved (several of the points I raised have been fixed). dllu (t,c) 21:21, 10 March 2013 (UTC)[reply]
  • Weak Support It is much improved. A few things make it weak though:
  • The spacing of the teeth on the front and rear seems inconsistent.
  • The chain seems a little thin/not to scale (take this one with a grain of salt)
  • The angle of the saddle isn't how a cyclist would usually adjust it (level).
  • The shape of the downtube is a bit wonky/not straight.

Update

  • Label lines are now red
  • Left pedal added; left crank not visible anyway and neither I think left handlebar (played around with it).
  • Ligthened the circles under the tyres to be less distracted- actually looks really odd without them though.
  • "Front set" is not an actual term
  • Head tube moved to frame per original FPC
  • Corrected some odd shaping of the seat post and seat tube
  • What do you mean by teeth, JJ?
  • The tyre tread on the wheels seem to be unevenly spaced. Also, I just noticed the sprockets are wrong -- the spacing between the teeth should be the same regardless of the size of the sprocket (smaller sprockets have fewer teeth) but in this diagram the smaller sprockets appear to be just scaled versions of the big ones. dllu (t,c) 21:27, 10 March 2013 (UTC)[reply]
  • Yes, the sprockets were what I was referring to. JJ Harrison (talk) 03:09, 11 March 2013 (UTC)[reply]
  • Pinkish areas now greyscale as far as I can see (some of them are very subtly coloured but I don't think that's a problem).
  • With braking systems with was mentioned on the first FPC but I think they merit a separate diagram and could confuse here, because it would be difficult to show how they operated properly.
  • The shading on the frame is illustrative of its shape. Whether realistic or not, I think it functions fine.
