Tours and activities startups that work with Airbnb guests themselves have also originated from the home-share company's model. These include I Bike Harlem, which offers bike tours of Harlem that expose travellers to the history and food of the neighbourhood. Less than a year old, it has already developed numerous relationships in the local Airbnb community, aided by the fact that founder Maxine Daniels is a host herself. Daniels' decision to start a bike tour company coincides with a trend - the steady rise in popularity of bikes as an efficient way for tourists to see and experience a city, paling in comparison to bus tours or even walking. According to Daniels, "Harlem is Manhattan's largest neighbourhood and biking is a great way to cover a lot of ground and get you close to the sites and people that make it special. The Airbnb traveller is someone who's very adventurous and biking is a great combination for that."
