Hi.  I'm  Jack  Foster,  and  I'm  a  Londoner.  I  love  my  city.  I  think  it  is  one  of  the most exciting cities in the world. 

I  enjoy  driving,  but  I  almost  never  drive  in  London.  For  one  thing,  it's  too expensive. You have to pay a congestion charge to drive in Central London. 

And  if  you  do drive  in  the  city,  you  spend  most  of  your  time  stuck  in  traffic.  And parking is even more expensive than petrol. 

So I always get around the city by public transport. 

London  has  a  great  bus  network.  And  the  Tube  is  the  oldest  underground  system in  the  world,  but  it  definitely  isn't  the  cheapest.  Public  transport  in  London  is much more expensive than in many other cities.

Luckily,  since  2010,  there  has  been  a  cheaper  alternative  to  the  buses,  Tube,  and cars in London. And it's a healthy alternative, too.

This  is  London  Waterloo,  the  busiest  railway  station  in  Britain.  And  right  next  to the  train  station  is  this:  one  of  the  many  cycle  hire  docking  stations  around London.

At  each  of  these  stations,  you  can  borrow  a  bike  for  making  short  journeys  around the city. About 3000 people hire bikes from here every week.
