Wow, you killed it handyandy1100! First picture is just great. I like it how there is almost no distance between the chainring and the chainguard.
That headlight is pretty sweet too.
My addition to the thread. I love reusing and repurposing the nuts from the V-brakes that I remove from donors. Here on the kickstand bolts:
Also the front brake reaction arm bracket on the same bike:
The bolts need those rubber cable protectors from the V-brakes, to look complete though.
Also this:
And this:
Then on this one I have brass nuts - only where the extension attaches to the frame:
Also valve rings/nuts on the seat clamp bolts:
I have some brass washers, I should replace them...
Same only these are the other type:
I love looking at art-work bikes, but anyone who's seen my bikes knows I personally have more of a propensity to remove "details". On the other hand, one set of details important to many of us here can go completely un-noticed by the public at large. Satisfying things like setting up a bike with wheels true and in the same plane as the steer tube and saddle, crank and chain line straight, bearings that neither bind or rock, etcetera, etc... But... since the OP was clearly looking for ideas about styling touches, I have two words. Tab delete.
I like to use small angle brackets to mount reflectors and lights on or near the rear axles. I've posted some of these in other threads before but I think they apply here in this one.
