Bike Anti-Porn - When Things Go Wrong

Changing one wheel size wouldn't affect the wheel base materially, by nothing if you kept the wheels the same size (i.e. changed both).

Eh?

Wheel base is measured at the point where the wheels contact the ground ie 100% straight down from the axles - on a bike with the same size of front and rear wheels and tyres (and this size is actually irrelevant, they could both be 12"wheels or they could both be 700c wheels) the axles will sit equidistant from the ground. We will call the horizontal measurement between tyre contact points with the ground 'X'

Imagine that there's a strip of tape or a piece of string stretched between the axles, on the forementioned bike with same size wheels and tyres this tape or string would be parallel to the ground - dead flat - horizontal. We will call the this measurement or line 'Y'

At this point, in the plane of X (in the horizontal direction it was measured), X=Y

Now change the size of either wheel. The tape/string will now be at an angle as the height of the two axles from the ground is no longer the same. We will call the angled line 'Z'

It is simple geometry that while X,Y and Z are all lines of equal length - because we haven't changed and frame or fork components which dictate where the axles are placed - in the plane of X, Y reaches further than Z.

Thus changing the size of wheels from 700 to 26" would have no effect on wheelbase and changing the size of only one wheel would actually shorten the wheelbase making the bike - presumably - better for polo.

Someone has a sense of humour!

what don't hate that bike, i think it's kinda cool...

^^ is that a plastic toy bike? :)

although i think it's quite cool, very custom indeed

I think its fugly, as well as the blue one.. sorry

That bike defines this thread.

I bet it's nice to ride however.

So much shite.

What the fuck is this?

haha, another golden example from that site

amnn yeah, and this too

Eh?

So what you're saying is that changing both wheels would have no effect on the wheelbase? And that changing one wheel wouldn't change the wheelbase much, that is to say not materially?

Which is what I said.

The geometry change resulting from different size wheels would far out weigh the minor shortening of wheelbase, which wouldn't necessarily make the bike better for polo.

IMO this is a disgrace of a paint job, reminded me of this:

VIDEO

Lol

RE: Homer Simspn bike.

lol,

for some reason I thought this was the logo on the rims:

its been so long since I've seen a set of Deep V's with the logo intact

On German E-Bay now 'Trendy bike 09' / 'Trendy oder Vintage look' Take note...

Bleurgh.

Beautiful, thinking of painting my Zipps up just like that lol.

Aww, I was going to paint hearts on mine..

bit of a shocker that site, i never really realised how many shite bikes there are! but beauty is in the eye for the beholder !

Pretty cheap source of Phils (etc) though, before Sterling died.

I think its fugly, as well as the blue one.. sorry

thats a lovely colour, same as the wrapper for canburys chocolate

Cornlieus (sp) blackfoot's bike is more purple than that ^ that's more pink!

this bike confused the fuck outta me. what's going on..?1??!
