One of the great things about triking is how nice it is to have everything right at hand as you roll along. With a SeatSide mount, you can have all sorts of things close at hand. The Azub SeatSide Mount lets you carry bags, water bottles, cameras, all sorts of things, right by your side. Snacks, phones, lip balm, you name it, now you can keep it all within reach while riding. This mount attaches to the main tube behind the seat. The SeatSide arm can be attached on either side, or both if you wish. The OneBolt option allows for quickly taking the mounting arm on and off. If you plan to go to a double sided mount in the future, order the OneBolt Release version for a super simple later upgrade.
