&ldquoArre cycle walon ko rasta do, yeh to paanch baje se chal rahein hai&rdquo The exclamation is only one of the many, all good-natured, that we encounter as we tackle the alleyways of Old Delhi. In the lead is the six-foot plus figure of Jack Leenaars, who has begun DelhiByCycle. The South Asia correspondent of the Dutch daily De Telegraaf, Jack has been living, and cycling, in the city for the last five years. Over that time he has developed an intimate knowledge of its sidelanes and byways, something that he decided to put to good use after he went on a similar bicycle tour organised by a Dutchman in Bangkok.
