How to Install Bar End Mirrors on a Wicked Thumb E-bike

Installing a set of bar end mirrors on your Wicked Thumb e-bike can be a straightforward process if you have the right tools and follow the steps below. In this tutorial and accompanying video, we will walk you through the process of installing bar end mirrors step by step.

Since there are many different styles of bar end mirrors, as well as different handlebar styles with different inside diameters, there will be slight variations in the installation process. Different adapter sleeves, collars, and modifications may be necessary to achieve a secure fit. In most cases, the necessary hardware is included with the mirrors, but if you get stuck, contact us or find a local bike shop to give you a hand.

Alright, let's get to it.

Tools needed:

Knife or flat head screwdriver
Five-millimeter Allen wrench
Electrical tape (optional, for certain applications)

Step 1: Remove the Bar End Caps

The first thing you need to do is remove the bar end caps. You don't have to worry about damaging them because you won't need them anymore. Use a knife or flat head screwdriver to pop them out. Different bars and different grips have different ends, but they all pretty much pull out the same.

Step 2: Remove the Adapter Sleeve

When you receive the bar end mirrors, you will notice that they have an adapter sleeve on them. This adapter is needed for bars with a larger inside diameter. Remove the adapter sleeve if it's not needed.

Step 3: Install the Bar End Mirrors

Using the five-millimeter Allen wrench, loosen the tapered nut that goes into the bar first. As you tighten this Allen screw, it will pull the nut through, expanding the sleeve. Make sure that the cone is headed towards the sleeve side. Just slide the sleeve into the handlebar and tighten until the tapered nut bites. Be patient because it may take some time.

Step 3.5: Add Electrical Tape if Needed

Due to the variation in bar inside diameter, some bars may have a little bit of play, or otherwise not quite fit snugly. In this case, use a bit of electrical tape and wrap it around the sleeve. This will make all the difference, and when you tighten down this screw, it should help achieve a secure fit.

Step 5: Adjust the Mirrors

Sit on the bike and make any necessary adjustments to ensure you can see behind you. After making adjustments, tighten down everything to secure the mirrors.

Installing bar end mirrors on your e-bike can be a simple and straightforward process if you follow the above steps. Just be patient with the installation process, and make sure everything is secure and where you want it before taking your e-bike for a spin.
