Design Weakness

The mounting brackets that hold the digital display on the ebike handlebars has failed again.  Twice I’ve attempted to repair the break in the mounts and both times the mounts have failed in a different location.  I believe it’s a design weakness.

Not wanting to spend the $100+ purchasing a new display I searched online to see if it was possible to buy replacement mounting brackets.  I thought this might be optimistic but to my surprise I found a seller on Aliexpress.   However the price of the brackets was $12.97 with an additional shipping cost of $18.23.  Did I really want to spend that much money on something that was likely to fail.

After  30 minutes of searching I thought I might have an alternative.   A seller on Aliexpress had CNC machined aluminium motorbike brake hose mounts and the hole for the brake hose looked very close to the size I required to mount the display.   Moreover the cost was $12.67 with free shipping.  I took a gamble I could make them work and they were delivered today.

You can see where I have attempted repairs on the original mounts in the photo below

After searching through all my ‘stuff that might be useful one day’ for something that might be used as a 10mm dowel in the hole of the new brackets I realised I could probably use the ends of the original brackets.

Below is how I plan to modify the new brackets.

I cut off the ends of the original brackets and then filed them down in diameter in order to fit them into the 10mm hole in the new brackets

Next I did a test fit

All good.  Time to remount the display on the handlebars using the new brackets.  I don’t think these brackets will break as easily as the originals.  AND they were cheaper!
