Most modern bikes come with a bottle holder as standard but how do you hold that Latte you just bought from Starbucks? You can probably get away with holding it with one hand while steering the bike with the other when the road is straight and clear but in the hustle and bustle of city life, it could get a bit awkward. Instead put your cup on a handy cup holder from Bookman. It clips to your bike's handlebar with a clever spring steel construction and doesn't lose its grip even on bumpy rides. It's not a permanent fixture so you can quickly put it on or take it off when you need to.
€29 but no longer available. See other stuff from Bookman
