28.6mm x 31.8mm Adjustable Bicycle Handlebar Stem, 90mm/110mm, 0-90 Degree Rise, Short Stem for E Bike

This adjustable neck adapter I purchased for one of my e-bikes. The quality is good and made the height on my handlebars at a much more comfortable height. This is the 2nd one I've purchased from this vendor. The product fits good. And the price is fair!

Fit perfectly on my fun hang e-bike. Easy install. Enables me to sit in a more upright position with less weight on my wrist and shoulders. Easily adjustable and sturdy.

High quality, very sturdy and adjustable.

Once installation was completed the new stem looks great. My product seemed to be assembled by strong gorillas as the hex nuts were near impossible to loosen. With a new hex wrench and vise help-mission accomplished.

This was a game-changer for me. The stem extension and its adjustable angle all but eliminated the pressure on my hand, wrists, and shoulders. I’m now able ride for miles without discomfort.

I needed to raise and better position my handle bar on an Aventon Adventure 2 for more riding comfort. I selected this model stem because it looked like the one sold by the bike manufacturer. The installation was straightforward and everything fit with no problem. The front half of the original handle bar bracket has protrusions on the lower two holes for mounting the headlight. This original front half lined up perfectly with the new rear half, so I used it with the new rear piece to remount the light. The new bracket screws are larger and the two lower screws must be longer because of the extra distance required to accommodate the light. I purchased two M6 X 1 screws at Lowes to finish the installation. The holes in the original front bracket half did not have to be enlarged to use the larger screws.

This stem is great. I used it to raise my handlebars on my commuter gravel bike to make it a little more comfortable for my daily commute. I read one review from a person who could not remove the wobble. They must have installed incorrectly, maybe did not tighten the top cap headset preload bolt correctly. This stem is beefy and very stable. It is not light weight which is no issue for this bike.

adjustment screw siezed ! hlad i had where i wanted it!

Perfekt
