Moved all mine to the right. Makes most sense with signaling turns to me.

Well, until I read this thread I had no idea anyone ever put the front brake on the left hand side. All bikes sold in the UK come with the front brake on the right, and I stupidly assumed that was universal. Maybe it's because we drive on the left? Though what that should have to do with it I can't really imagine...

A customer brought in a bike for a tune-up that he had switched (not very common).
Part of the tune up is a test ride. The mechanic hopped on the bike rolled around the parking lot to verify the gears shifted properly, the stem and seatpost were snug, and then checked the brakes....and went right over the bars.

Left for front brake.
Just because it is SOP on most bikes (and all of mine, and we are way into double digits here).

Enjoy

All bikes in the US are the opposite. Weird. I prefer mine on the right, too.

well, sorry to hear the guy got hurt.

The guy I replied to is used to right side braking, so he should redo the new bike so he doesn't get himself hurt by accident

Left out of habit. Most of my bikes are geared:

Right side: brake lever operates rear brake. Shifter operates rear derailleur.
Left side: brake lever operates front brake. Shifter operates front derailleur.

Left = front
Right = rear
