Left-leg biking

From Carls wiki

When going over rough terrain, I've begun to hold out my left leg a bit, and leaning the bike ever so slightly to the left, so that if I were to lose balance, I could easily land on the left foot.

With time, I've found this motion to have several other advantages.

Signaling

Raising my left leg a bit more, I can replace the usual hand movement in critical left turns, for example when crossing roads. This allows me to retain both hands on the handlebars.

Maneuvering

The left-leg technique not only gives me an extra safety on non-flat ground, it also allows me to exercise more fine-tuned control over small sideways movements, which means that I don't have to slow down as much when going through small passages, for example.

Sled

Putting down my winter boot-clad foot and letting it scrape against the ground, I can go down Slottsbacken without braking.

To a lesser extent, I also use my right foot for all the above purposes.
