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.

Sigh. I remember as a kid we had exactly that device mounted on a rear rack.... That was 43 years ago.

Clever! I think, though, that a heavy pillion rider would be risky, especially it he/she leant back. Wheee! Up goes the front wheel.

The addition of the seat-pillow is nice, and the mini-footlocker is very cool. But, how on earth does this rate more than $40-50? It's not exactly ground-breaking.


Problem with this is that most bikes are simply nowhere near being sturdy enough to take up to 90kg (that is the weight of a large adult).

Tandem bikes are engineered for the extra weight, having reinforced wheels, usually very strong brakes compared to an average 'city bike', a much longer frame, and most importantly, an extra set of pedals.

This seat idea might be fine for a kid who has outgrown a child seat however. I'd still want to see better footpegs and something to prevent feet accidentally getting caught in the spokes or gears.


Two comments about safety: 1) none of the riders uses a helmet 2) the child in the picture barely reaches the place where the feet should rest. Also it's very easy for a child, to introduce his foot in the wheel and receive a very dramatic lesion.

A neighbor of mine designed and built a saddle type seat that clamps onto the frame between the regular seat and the handlebars. It's only for small children but it has foot pegs and the child can hang onto the handlebars.

I did a patent search for him and found various versions of the seat patented as far back as 1890.

Come up with something new next time.

This is so old as the way to Rome. My mother brought me to school on her bike about 50 years ago. That one was even better because the cushion could be mounted on whatever good and stable carrier. not this flimsy thin wire-frame that is shown on the images

BTW. this is forbidden for safety reasons in some countries and right so. Have you ever had your heals in the wheel? it hurts. and you will fall both of you on the street under a bypassing car ......

Can we get a European version rated to 75kg? ;-)
