Sounds pretty dangerous, riding on the pavement!
How to get on a bike - for pillions.
The man gets on the front and holds the bike upright.
The lady stands to the left of the bike and puts her left hand on the Gentleman's left shoulder.
She then puts her left foot on the foot peg.
Step up on just that foot using the hand on the shoulder to help. You should be standing on the footpeg with one leg - the right leg hanging free.
Put right leg over onto the other side.
To dismount she just stands on the footpegs then does the same in reverse - but not without telling him first.
What do you mean, sexist?
