I ride my Sorty back and forth through the mad traffic of London daily regardless of the weather (almost) without worries, feeling as safe as one can on two wheels. A couple of days ago, for old time sake I decided to do a run on a push bike. I couldn't believe how unsafe and threaten by the other road users I felt. I never have had these feelings on a motorbike. Without the possibility to give the throttle a quick squeeze if necessary, being much more difficult to see and without the protective gear I felt extremely vulnerable. It has given me a new sense of respect for cyclists (even though I think that they should stop when the traffic lights are red as other road users).
