Something further.... A vague & equally pointless remark was made early about the length of tandems, recumbents, etc. making them hard to OTB under front brakes.
I race recumbent trikes (<see avatar). The design limitations imposed by the rules we race under mean "Formula HPVs" as we call them are inherently front heavy, and it's actually quite easy to lift the rear wheel under hard braking. Two front brakes tend to help that too. But the underside of the nose prevents any big problem.
There has been discussion among the racing scene questioning the need to have rear brakes at all, because they are so ineffective.
Believe it or not, the rear brake actually does its best work when used as a form of traction control under acceleraton on a wet track! You squeeze it on enough to load up the rear wheel, and select the gear to give an appropriate cadence & power delivery to match the wheel speed out of the corner. The brake loading prevents wheelspin. The thing is, not a lot of riders have discovered that you can do this, so it's kind of my secret weapon.
