I includes any and everything you need. Including street scene live cams (Harlem based cams), maps, parking resources, even applications to request that commercial building owners let you park your bike on site! Check this and more out at their site.
Also remember that once a Summer NYC gives out free helmets – I got mine last year! Looks stylish and offers great protection too.
Also perhaps most importantly, don’t forget that if you happen to be biking in Harlem please stop by the bikeshop Modsquad.
