Companion Bike Seat Review

Earlier in the spring we got a chance to test out something called the Companion Bike Seat. Basically, this product gets installed on your bike much like any pannier rack would. The difference is you can actually carry a passenger (up to 200lbs). In addition, it has a lockable storage area to place anything you want that could fit in there.

The only bike in my collection that I was able to install the Companion on was my wife’s Nirve beach cruiser.

Installation was a breeze; no more than 15 minutes using basic tools such as a socket set and allen keys. What you see below allows the rack to be secured onto the seat post. You can fully adjust the pitch of the seat. If the bike was bigger or the post was further away, you can adjust this strut to ensure a proper fit.

Reflectors on the rear of the seat. You can see from this angle the lock for the trunk.

Heavy duty constructions allows for a 200lb passenger. Notice the pegs? That’s where the passenger places their feet and they are what the rack mounts onto. The rack itself has a wide stance, which means that it mounts somewhat wide onto the pegs. This makes the seat stable especially when you’re turning or if you’ve got a heavier passenger. One of the tests we did was to see if it would flex/sway when taking sharp turns. When riding through sharp turns with an adult male on the back, the rack didn’t sway/flex. If anything it’s the passenger who ends up getting nearly tossed off the seat. Just keep in your mind that this rack is pretty burly and VERY stable.

Lockable storage trunk. Perfect for food, electronic devices, cigars and donuts.

It is in our opinion that the Companion Bike Seat is a well made product. During our testing phases, nothing broke or had any type of issues. Our passengers all said that the cushion was very soft and that the rack felt stable. Our only complaint with this product…actually two complaints:

The first one would be that you can’t use it with a quick release wheel. It has to be installed on a bolted axle. This means it won’t work with a Nexus hub or any other type of internally geared hub that has a shifting mechanism on the other side of the dropout. Another complaint would be the inability to hang panniers. Sure you can place things in the storage trunk, but what if you’re picking up your kids from school and they have books to carry or if you’re doing a groceries run? It would be great to see their future models have some sort of mounting/hook system that gives that option.

Other than that, it’s a pretty great idea. There really hasn’t been any other products to my knowledge that works like this. Most rear racks have a load capacity of no more than 60lbs. But the Companion
Bike Seat is capable of carrying 200lbs. If you think about the alternatives in the bike world in regards of being able to carry 200lbs, you’d have to spend quite a bit of money for a cargo bike or something like the Xtracycle. I’ve owned cargo bikes and an Xtracycle before. They’re great and all, but they’re big and bulky. Yes I do realize that the Companion doesn’t have the same load capacity of an Xtracycle, but I used mine to carry my kids about 90% of the time that I owned it. So with that in mind, having a product that costs a fraction of the price of a cargo bike, but gives you the ability to carry a passenger would be a WIN WIN in my book. Just think about it, $149.95 isn’t much. With this simple product you can now carry your kids, go on a date with the wife/girlfriend or go bar hopping (you as the designated driver).

The Companion has an MSRP of $149.95.

    Beware that this is illegal in several countries – two adults on a bike designed for one. Your laws may vary.

    I noticed that it has a weather strip for the lid. How well did it work at keeping things dry? Would you have to empty it out when you wash the bike due to the possibility of a water jet aimed directly at it?

    Yeah, you’re right, Gunnstein, but here’s a quote from the 1975 movie The Wind and the Lion:

    Hi B Pugh – We did pretty extensive testing on the water seal to make sure water didn’t leak into the stash-box, using a hose to spray water directly onto the seat ( It ended up taking the factory an extra 4 months to source material for the gasket that worked for our needs before we started manufacturing our bike seats. I hope that helps!

    Yah, I talk about this bike seat on my blog as well. Basically, it’s a good idea, but not perfectly delivered. I use it every day with my son on the back (he’s 10), but I really can’t wait to take it off when he’s a bit older. Riding with a free-loader on the back isn’t as fun is it might seem. See my “review” at –

    They now have them with pannier hooks and an optional backrest.

    Anyone found that the excess weight from this seat plus passenger (in my case, a 7-year-old), plus whatever weight from panniers, etc. kills the back wheel on your bike? I installed the Companion seat on my Electra Townie Go about a year ago and I’ve broken 2 back fenders and had countless flat back tires (now needing to get a whole new tire and the mechanic says I shouldn’t have so much weight on the wheel). Disappointed if this is the case; it’s otherwise been a good kid-carrying solution and I’m hesitant to shell out on a full cargo bike after all the money I put into this one.
