Mount a Bicycle With Toe Clips

This will explain, with full detail, how to mount a bicycle with toe clips. ^[1]

Steps

Straddle your bicycle frame, forwards of the seat. You can lean the bicycle and swing your leg over the seat or the handles, whichever is easiest.
Position the left pedal at the 10:00 position. That's rotated forwards just a bit from the top of the stroke.
Put your left foot into the left toe clip.
Push down with your left foot.
kick off against the ground several times to gain enough momentum to safely swing your other leg over.
The resistance of the bicycle should raise you up and allow you to slide back onto the seat.
Pedal a few times to reach a stable maneuvering speed, especially in traffic.
Flip the other pedal with your right foot and slide your foot forwards into the pedal.
Now you're ready to roll!

When getting onto a bike this way, be patient,as it takes a little bit of practice.
If you're left-handed, your right foot may be the correct choice to start with. The idea is to use your more dexterous foot to manipulate the other pedal while you're in motion.
If you don't get enough resistance when starting to come up and onto the seat, start in a higher gear.
Remember to always wear a helmet when riding a bicycle.

It's especially important in traffic to reach a stable maneuvering speed before fiddling with the clips on the other pedal.
