Finally! A good way to mount vertically oriented rear lights on the backs of recumbents! Rear lights are important for safety. Recumbents often don't have good places to mount them, especially if the light was designed to go on a vertical tube like an upright bike seat tube. How do you create a vertically oriented tube on the back of a recumbent? With this! This mount attaches to almost any tube in almost any orientation, and allows you to create a vertically oriented tube sticking up from it. The locking swiveling clamp system is super simple and holds really well. Simply snap the clamp over the tube you want to attach to, swivel things around until they are lined up the way you like, and tighten the bolt. Attach your light and away you go!
1. What does this do?
It attaches all sorts of places on oddly angled tubes and creates a nicely vertical or horizontal place to mount things like lights. It's really handy for mounting rear lights on recumbents.
2. Where can I put it?
Almost anywhere. Higher is usually better with rear lights. The clamps are available to go on round tubes anywhere from 1/4 inch up to 1-1/4 inch. Tubes smaller than 1/2 inch require a rubber shim; the rubber shims are 1" outside diameter. So- things like rear rack rods are now available for attaching lights!
3. Will it hold my light?
If your light is any normal sort of bike light, yes. Anything of a reasonable size and weight will work.
4. Really? That simple?
Yes, really.
Decide where you'd like to attach a light. Tubes at any angle are OK, as long as they are between 1/4 inch (6mm) and 101/4 inch (31.8mm). So things like horizontal tubes across the back of the seat, seatstay tubes that angle up to the back of the seat, all those are OK. Measure the tube and order the corresponding clamp.
Remove the bolt from the clamp assembly and set aside. Snap the open clamp around the tube where you want to attach things. Reinsert the bolt and start the threads.
Swivel the light mounting tube around to the orientation you want. Keep in mind the light mounting tube can be positioned to the left or to the right of the tube it's attached to; if in the course of your swiveling things around, it winds up on the opposite side from where you want it, remove the clamp from the bike/trike, rotate the clamp 180 degrees, and snap it back on. It will now swivel to the side you want.
When things are lined up the way you want, tighten the bolt. If the clamp is not tight enough, you may need to insert some of the provided grey plastic shim. Start by trying the entire shim; if that's too much, cut off 25% and try again until the fit is right.
Attach your light.

Used to mount both lights and mirrors on my handcycle. Worked like a charm.

An excellent Mount for my taillight.

I’m happy with my rear light extender. It raises my rear light up to a level where it is more visible to approaching traffic from behind me. Now, if I just figure out how to raise my front light I’ll be more comfortable riding in trafficy areas.

Outstanding customer service from Terra Cycle and the vertical light mount I purchased is equally as great!
Kris M. 5/5 Verified
Excellent product to solve difficult mounting problems. Lots of ways to use it.
Marty F. 5/5 Verified
The top bar on my 700 is full. So I had to mount the rear light on the angular part of the frame. Using your adjustable light mount was necessary.
Robert W. 5/5 Verified
Used 7/8” id by 1 1/4” od tubing sleeve to accommodate seat post style clamp for my blinkie.
Gregory K. 4/5 Verified
Worked just as I imagined. Had no place to mount my rear view camera on my bike and this was the perfect solution.
Roderick P. 5/5 Verified
Wouldn’t use anything else. Perfectly designed for its purpose. Adapts well to any angle and forward/rearward tilt. Can be used front or rear, vertical or horizontal, or on angled rear frame support. Replace tube with any length for elevated light above rear pack.
Elliott D. 5/5 Verified
I like how sturdy the mount is, but with the teeth so tiny it can easily move if you put pressure on it. Other than that, it’s a great product.
Martin M. 5/5 Verified
Needed something for my light to be higher than my bag so I would not have to take my bag off every time I ride. This is very well built, makes for a real clean install and works perfect

I have a different situation, in that my tail/brake light turn signals, and LED laser lane projection indicators are made to mount on a seat post. I did build a structural frame for my fully cantilevered canopy secured to the back of the factory seat frame, and fortunately had a horizontal tube in the perfect position to mount this vertical rear light mount. Just what the doctor ordered. In fact with my other flashing lights it's situated so that it looks exactly like the third brake light used on cars! Thanks again for another quality product.

Used to mount wireless computer on a recumbent with 1.125 diameter clamp. Cut 4" tube to 3" length, reinsert end plug and clamp around stem riser, since almost all current wireless models only have a range of 70cm from front wheel sensor to computer they will not function when mounted on the handlebar.

just what I needed, ordered a second!

Used it to attach to an Ortlieb quick rack I have on my commuter bike. Good solution!

Great product! Enabled me to place a safety light in a much more visible position.
Mary J. 5/5 Verified
Instead of the intended use, I used it on the center front post of my trike to mount a headlight.
Marshall W. 5/5 Verified
Purchased the 1 inch mount but needed the 1 1/8 which was correct fit. Looks great on my AZUB Ti Fly 26. The mount was for my Garmin Varia RTL515.

This made putting an additional flasher on my rear rack easy when nothing else worked. Highly recommend!

fits and does what I wnt it to.
Maurice D. 5/5 Verified
Added to my TerraTrike Rambler to give me a good place for a rear light mount that is above the pannier rack and rack bag I usually run. While I do also have a rear light on the rack, this provides me good option for mounting an additional light. Most rear lights are designed around seat post mounting, not a candidate for trikes. Installed easily, well made and secure. Good engineering.
James H. 5/5 Verified
The adapter is perfect for mounting my rear light to my rear rack. My only minor issue is I needed another space in addition to the one included. Otherwise I would give it 5 stars. Still a quality product.

It works as it should

Be aware that the diameter of the post is 3/4" which is smaller than the mount for the Garmin Varia. I was able to find an alternate mount that fits 3/4" but the mount shipped with the device quickly stretches to be too loose on the post.

The excellent quality and precision aftermarket products from TerraCycle has really added to the appearance and functionality of my Ice Trike. Thank you for providing these Made in America after market products.

This is, of course, more than a rear taillight mount. While installing an e-assist on my Gold Rush, I found that the handlebars had no good place to mount the controller. The T-Cycle "tail light" mount mounted horizontally allowed very convenient and readable placement of the controller part way up the "U" of the handlebars. T-Cycle components never fail to please! BTW, the T-cycle dual tube battery mount worked very well on the Gold Rush.
John Y. 5/5 Verified
I have a standard commuter bike. Due to the shape of my handlebars, the orientation of a horizontal mount could only project light through the brake and shifter cables. I needed a vertical light mount but had very little bar space to attach a mount. The Terra Cycle team helped me find a Vertical Rear Light Mount model that fits perfectly and projects light right where I need it. I highly recommend Terra Cycle for their products, knowledge, and customer engagement.

Worked perfectly, very well made.

The mount works perfectly on my new ICE Adventure.

I needed a way to mount a Garmin Varia RCT715 on my ebike. I have a suspension seat post, so I couldn't mount it there. The rear light mount attached to my rear rack, and povides a stable mounting location.
