Made of very high quality metal. It is not huge so look at dimensions before buying. Works great for me!

The Accessory Extension Mount is too small for most uses. For the same amount, I can buy one that is 11 inches long and provides much more usable space.

Great bike , kickstand was my fault entirely. Lost a screw in the fender as well.

Because the Bafang display and controller takes up room in front of the handlebars/stem, there was no place to mount my beloved Ortlieb handlebar bag. This extra mount bar, in front of the handlebars, enabled a way to attach the Ortlieb handlebar bag, out of the way of the control display. There is space left over, on each side, to add extra things on each side of the bag.
