If you're someone who would prefer cycling into the gullies of Delhi, instead of taking a walk, then this cycling-cum-walking tour organisation will not leave you disappointed. They conduct various curated and immersive experiences in all parts of the city, and they have something for everyone. Well, everyone who knows how to ride a bike, at least. Their Shah Jahan tour, which covers Old Delhi comes highly recommended. Also, their website is one of the easiest to navigate and book through.
