Amsterdam has 881,000 bicycles. The estimate is based on  using the 
Wisdom of The Crowds. This is the average of the estimates  obtained from experts, being in this case the Amsterdam cyclists  themselves; 2600 panel members who filled in a survey about cycling  policy made by the 
Research & Statistics department of the City of Amsterdam. The average of all the responses came out to 881,000  bicycles. The survey also showed that seven out of 10 Amsterdam citizens find  it enjoyable to cycle through Amsterdam (23% found it very enjoyable),  and just over 1 in 10 find it (very) unpleasant (11%). The rest give a  neutral response (neither pleasant nor unpleasant, 19%). The cyclists that find it pleasant add that it is a fast an easy mode  of transport (50%), that they enjoy the surroundings while on the  bicycle (19%), and that is sportive and healthy (19%). The good bicycle  lanes and facilities and low costs are mentioned less frequently  (respectively 9% and 6% of the respondents who find cycling enjoyable). Less pleasant aspects mentioned by cyclists are antisocial traffic  behaviour, insufficient safety, and scooter nuisance. Some locations in  the city are avoided because of the difficulty of parking bicycles  there. Most often mentioned in this context is Amsterdam Central  Station.
