Back Brake

Motorbikes

Almost all motorbikes have a clutch, therefore the back brake is down at the right foot.

Bikes and Scooters

Bikes and scooters do not have a clutch and therefore have the back brake left hand

Front Brake

Is right hand, and should be on everything. But be aware, some countries use the left side for front brake on bicycles.

What are you used to?

If you are used to clutched bikes, you don’t want to accidentally grab the rear brake thinking it is the clutch. This hasn’t been a problem for me, but I don’t have the years on motorbikes others do.

Case for foot

Consistent with motorbikes. This one is tricky, since it isn’t consistent with bicycles or scooters. We switch between cars and bikes and motorbikes.

The rolling on a hill argument is interesting. The idea there is that you keep right foot on the brake, and won’t roll, thus releasing your hands. Where as with hand brakes, you can’t use both hands. However, the opposite is true, you can use both feet. This doesn’t stop the roll, but can present you with a more stable ground, especially as a beginner.

Case for hand

Finesse. I find the gentle tacktle response far better control that using my foot. And it means I can wear chunkier boots when riding as I don’t need feet finesse to control gears and brake.

Conclusion

For me, no question, hand back brake on the left handlebars is FAR superior to a foot brake. I also totally understand people who have ridden for years tripping up on this.
