No, I don’t mean ‘free drinks’ and I haven’t tried one myself.
‘Dinking’ was the old Aussie word for giving someone a lift on the your bike, back in the days when such things were legal.
It’s still a common way to get around in Amsterdam, though the idea of offering and/or accepting a ride from a stranger is probably (1) a cool marketing exercise for bike hire company Yellow Bikes and (2) likely to give a new meaning to the phrase ‘pick up’.
Anyone accepting a ‘Yellow Backie’ dink from an already wobbly rider like me would be taking their life in my hands. They’d need a stiff drink afterwards.
Look at the YouTube video above and see what you think of the idea.
