The Fidlock Twist bottle 800 + bike base makes it easy to take a bike bottle with you. The practical combination of drinking bottle and bike mount is held together by magnetic force. The bottle stays in place on the holder and does not slip off on the way. This is made possible by a flexible, resistant belt (belt-only technology) around the bottle, which in turn is screwed to a special connector that is firmly attached to the bike. The Twist bottle has a capacity of 800 milliliters.
