Doubling another person on your bike isn’t always the easiest (or safest, or most legal) thing to do, particularly if you have them perching on the handlebars, or sitting on the saddle while you stand up and pedal. Things are somewhat easier if they sit on your rear rack, but that’s not what it’s designed for. The Companion Bike Seat, however, is designed for just that purpose.

The Companion has the same basic form as a rear rack, but includes a padded seat cushion, foot pegs, and is sturdy enough to support a rider weighing up to 200 lb (90.7 kg). Beneath the hinged seat is a splashproof lockable storage box, should you wish to also carry some inanimate cargo.

The rig weighs 8 lb (3.6 kg) and reportedly fits onto a variety of frame sizes and styles, that incorporate wheels up to 26 inches in size. A rear thru-axle that uses locking nuts (as opposed to quick release levers) is required in order to attach the foot pegs.

Potential buyers can pre-order the Companion Bike Seat now, for US$124.95. The first 100 orders are expected to ship on or before Sept. 6th.
