I recently purchased an Aventon Level 2. I immediately realized the handlebars were too low and too far forward for me to get a comfortable ride. So I purchased this adjustable stem. It worked but one of the brake cables was too short so I took it to the local bike shop to get the cable re-done.This stem fit perfectly except the holes to mount the headlight did not line up, plus a couple of the adjustment screws were installed pretty tight but I was able to loosen them. Oher than these issues I was able to fairly easily install it where I needed it and it works very well.

My husband and I purchased Aventon Level ebikes. While we really like our bikes, our backs were getting sore due to the forward position of the handlebars. Being in our 50's now, we knew that stressing our backs was not a good idea,.l so we purchased this stem for our bikes to see if it helped. It was fairy easy to install and allowed the handlebars to be the perfect height to allow us to sit in more upright potion. In my opinion, it is a great value for the money as well.

I’m a tall guy and needed to raise the handlebar on my new Himiway Zebra D5, this stem riser worked perfectly! It looks really well made, everything fits with precision so you know someone put a good bit of engineering into it! Be sure to maintain spacers that worked with your previous stem, you’ll need those to tighten everything up. I’m very pleased and definitely recommend this stem riser, 5⭐️

I bought a FOMTOR 31.8 Adjustable Stem 0~90 Degree 90mm 110mm MTB Adjustable Bike Stem to use on my Aventon Aventure. Now I am not sure what to do. The stem came with no directions at all. Just the stem in a plastic bag. Loosening the left and right screws was impossible. One side simply would not loosen. I'm pretty strong and I have good tools. The whole fitting would turn if I really got aggressive with it. But it absolutely wouldn't loosen. This made getting on the actual stem bolt difficult. I managed to get it assembled but I'm not sure I trust it.

We bought 1 first to try it out and then bought a 2nd one for my parents Level 2 e-bikes. The factory stems were much lower and even my hands would start to go numb just after a short ride so I knew we needed to get a setup that raised the handlebars for more comfort. My dad said the installation wasn't that bad and the adjustment range of the stem allowed the handlebars to be raised to a comfortable level. We went with the 90 degree height stem due to the cables and it was enough to make the bikes more comfortable, even without going to the full 90 degree setting. The only downside was the factory headlight would not fit back on with the new stem, so my dad made a couple custom brackets from aluminum to remount the headlight and everything was good as new (even better). I've attached a couple before and after pics along with the custom aluminum brackets for the headlight.

I love my Aventon Level, but I needed an articulating stem to achieve a better fit. My wife and I are in our mid-sixties and prefer a more upright riding style. Aventon's stock handlebar stems don't give us sufficient range to customize the fit of the bike to our preferred posture. The Fomtor adjustable stem installed in minutes and was easy to tweek. We have much more comfortable rides now, which allow us to ride farther and longer than before. Highly recommended.

Some of the reviews cautioned about the weight of the stem but i was still surprised by how heavy it was compared to the non adjustable stem i was replacing. Hoping the weight means it is sturdy and long lasting. The adjustment lock/button needs to seat and tighten properly to avoid play while riding. The stem has a built in top cap and adjustment screw.

Bought this to help with a shoulder injury. Waited 3 weeks for it to arrive. Ended up receiving a defective, dented stem that's missing 2 bolts and has clearly been used. Now for the icing on the cake, as other reviews mention, it's impossible to adjust and completely useless. Should have known better than to buy cheap trash.

It was easy to install, it did exactly what i needed. My bars are now higher and slightly further away and my riding angle is better. I would have given it a 5 star except one of the allen screws on the pivot part was impossible to loosen to change the angle on the bars. Luckily the angle was OK. I even tried a breaker bar and an small impact wrench. It would not loosen. This was not critical as the angle was close to what I was working with. Seems to be good quality construction, nothing has come loose or feels weak.
