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 Catrike 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 version of the SeatSide Mount for Catrikes attaches to the seat frame. We make other versions that attach to the main frame tube. We recommend this version of the mount for people that simply want a good sturdy place to mount things beside the seat. If you want maximum versatility in where things are located or need quick on/off removability, check out the main frame mounted version.
1. How does it work?
Specially machined clamps attach to the seat frame. For Catrikes that don't fold, they go on the straight part under the seat between the main tube and where it bends up. On Catrikes that fold, the clamps go on back of the seat near where the seat angle adjusts. A support tube comes out sideways and over to where the accessory mounting tube needs to be. The end of the support tube has a T clamp that holds the horizontal accessory mounting tube. The accessory mounting tube is long enough to hold whatever you'd like.
2. I've seen ICE trikes with something similar. Is this like that?
The stock ICE side mount is vaguely similar, but it has a smaller accessory mounting area than the ones we make and is only adjustable left/right. On our mounts, everything is clamped, not welded, so you can adjust things up/down, left/right, and forward/back. The space provided to mount accessories is about 3 times as long. If you want to really customize it, you can shorten any of the tubes, or even substitute another of a different size. We make a version for ICE trikes, too, of course, in which case the mounts would be very similar. On the ICE trikes, the tube that you attach to is behind the seat, rather than under the seat, so how you get from there out to the side of the seat is a little different.
3. Which side does it go on?
Either, or both, it's up to you.
4. Will this work with any bag?
Yes, the tube where the accessories mount is 7/8in (22.2mm) diameter, so pretty much anything designed to mount to a bike or to handlebars can attach there.
5. What can you put on it?
Anything that you can attach to a standard 7/8in (22.2mm, standard handlebar size) tube. Handlebar bags, water bottles, phones, things like that. The supplied accessory mounting tube is 11 inches (28cm) long, so you have lots of room. We have longer tubes if you really want to go crazy.
6. How much weight can it hold?
A lot, but obviously it has it's limits. We're saying 10lbs (4.5Kg) to be on the safe side. We do recommend that if you want to carry living things (like pets) that you do so carefully.
Installation is straightforward.
- First, you attach the clamps to the seat frame under the seat.
- Next, you assemble the accessory mounting tube to the T clamp on the support tube.
- You then slide the support arm into the clamps under the seat and adjust the system to the left/right, up/down, and forward/back position you'd like.
You're ready to install your accessories!
- We include a user installed catchpost in case you want to use a handlebar bag that is designed to index to the handlebar stem on an upright bike. Some handlebar bags have a cable or an arm that is designed to catch on a handlebar stem to keep the bag from rotating down. The catchpost provides a place for that to connect.
- We make a lot of tubes and clamps that are compatible with this system if you need to do customizations. Check out the Seatside Mount Hardware and Cockpit Mount Hardware pages for more information.
- Clamps are CNC machined aluminum, anodized black, with all stainless fasteners. Tubes are black powder coated aluminum with removable black end caps.
- Fits all Catrikes (and possibly Musashis, haven't tested that yet).
It’s the Best
Excellent! Now let’s remember what we’re talking about here. We’re taking a bar that is long in one dimension, bending it to travel in a second, and bolting on another bar to travel in a third. Then we’re hanging a load on the end to torque the whole thing both vertically and rotationally. This can’t be done right unless the whole assembly is done right and with quality parts. I’ve had my mount for a month and am only surprised that it’s required tightening only once, just after my first ride.
