Ever wanted to attach a computer, GPS, motor controller, or phone right near your hands? Ever wanted to attach something like a mirror to the ends your handlebars, but you have Bar End Shifters, so there wasn't any way to do it? Well, now there is! This mount uses a special clamp with a Cable Tunnel in it that attaches to the end of your handlebars right under your Bar End Shifters. The clamp extends forward and inward a little bit, and holds the T-shaped mounting tube that goes up and over. Since the clamp goes inward a little bit, your hands slide right past it. You'll barely notice it's there as you go from braking to shifting and back. What you will notice is that your mirror is now right where you want it to be, and that you can easily see your phone and operate the buttons on your motor controller. It can be installed on the right or left side of the trike.
1. What does this mount do?
A lot of trikers would like to mount accessories near their hands. When you have Bar End Shifters, the ends of the handlebars are full and there's no place to put things. This mount solves that by providing a clamp with a notch in it to go around the shifter cable. We make two versions, one for when the cable is in the front, and one for when the cable is in the back.
Since your hands need to move up and down from the brakes to the shifters and back, the clamp is angled and specially shaped to stay out of the way. It's curved and doesn't have any sharp corners, so as your fingers brush past it, you'll hardly notice it's there. The L shaped tubular mount goes up and out, putting an adjustable height horizontal tube about 2 inches (50mm) above and in front of the shifters. It works on both the left and right sides by simply flipping the components around.
2. What can I put on it?
All sorts of things- mirrors, computers, phones, GPSs, motor controllers, etc. Anything you want close at hand.
3. Can I use it as a hand rest?
Yes, it's strong enough to rest your hands for a while as you ride, but we don't recommend you use it to actively steer your trike. It's designed to be a lightweight accessory mount, not a handlebar extension.
4. Can I use it as an exit assist?
Unfortunately, no. The handlebars themselves are often not strong enough, and the clamp is designed to be small and light and it's not strong enough to hold that much weight. We make actual exit assists as well, they are made very differently.
5. How hard is it to install?
Not hard at all. You don't have to decable the shifter, but you do have to move it up temporarily.

Thought the shipping price for something this small was to high.

Removing the shifter and putting it back really messed up my shifting. I got most of the gears back, but still have some noise on some gears. I will have to recalibrate the derailleur. you should make the clamp in two halves so that you don't have to remove the bar shifter to install the T-tube.

The bar end shifter mount enables me to get my phone and electric motor display up where I can see it.

This is a great accessory mount for any bike or trike that has bar end shifters. It provides a very secure base for accessories and at the same time doesn't get in the way of the riders ability to use the brakes.

I evidently missed the small print that stated do not include the L tube. The picture with the ad is very misleading. I am a bit disappointed at best.

They are great. Holds my Garmin and both mirrors just perfect. I had to remove the plastic bar end caps and cut the short inboard side of each bar (make them less like a "T" and more of an "L") because my legs kept hitting those as I pedaled. I left a quarter inch beyond the verticle bar and reinserted the plastic bar end cap. I is perfect now. Highly recommend Mike in Beavercreek, Oregon

Been using your brand of parts for my trikes for years and continue to be pleased with the look and fit. They just don’t look like aftermarket parts. THX so much!
Bill W. 5/5 Verified
works as needed, well made, kinda pricey though
Mary S. 4/5 Verified
I installed this bar end shifter mount along with a one had operated dual brake lever to attach a remote control for my drone. It also provided a space for another mirror. The installation was very easy. Following the instructions made the installation a snap. Two thumbs up. The only negative is the price, ouch!
