For this, I steal brandon1945's Trek 4300 which I find muoy bueno.
Now folks, isn't this a classy looking bike? How does one make a bike look so nice? The answer is simple and will be found in someone else's post.
(Give tips on how to make your bike look classy)
These are mine:
Add decals on your bike (Preferably with primary colours including white and black)
Do not clean non clean necessary items (frame but still clean components)
Get a seat post and stem and handle that have lots of writing on them.
Get tires that have lots of writing on them
Get a 2 toned colour saddle commonly found on Giant Bikes
That is all.
