Gerald's statement implies that "style" drives the rationale for not having a rear brake.

I choose to ride without a rear brake because at lower gear inches I can brake as effectively with my legs as with a rear brake, and, without a rear brake I have more incentive to develop the skills required to brake with my legs.
I find riding without a rear brake makes the whole experience much more interesting, and richer.

As one develops the complex and subtle skills associated with leg braking, the level of control and balance escalates dramatically.

Get rid of the rear brake, make a conscious effort to not use the front brake, and watch the control improve.

I would someday like to ride without a front brake.

I think I would need to ride for a year without touching my front brake before considering removing my front brake.

I suspect I would need to gear down to about 68 gear inches before this would happen, which means I would need to improve my spin to where I can get around town as quickly at 68 inches as I do now at 72 inches and formerly did at 82 inches.
