Game-changing upgrade!
The CXWXC Adjustable Stem (31.8 × 90mm) completely transformed my ride. Installation was quick and straightforward, and the wide adjustment range made it easy to dial in the perfect upright position. The build feels solid and secure on my e-bike—and the improvement in comfort was immediate. Wrist, elbow, and back strain are basically gone, and I finally feel relaxed and in control while riding. If you’re looking to improve comfort and posture without changing handlebars, this stem is an absolute must-buy.

Saved my life! Really
So a little history about me, I just turned 50, Medically Disabled from the fire Dept. Hadn't ridden a bike in 30 years. I used to race as a kid, and it's been my dream to get a bike for years. 25 years of Fire Fighting has left my body pretty tore up, and fat 340lbs. As MLK said though "I had a dream". Loose weight and eventually cycle again. I started on the recumbent stationary bike at the YMCA, and could barely pedal. I'm 100lbs down now I finally had moved to a standard seat stationary bike. I began to feel better, and I wanted a bike bad. I Could only afford an online bike, but I got the one of my dreams. Problem was I didn't even get to sit on it before I bought it. Fit was going to be an issue. My back has L5:S1 issues, and I have 0 flexibility. I need a boat load of stack. It enabled me to finally have a comfortable cockpit. The Stack is HUGE at 40 degrees, and the shortened reach which aids in the stability of my position. All for 20$. Saved me a 200$bike fit for now. It is definitely worth the money. Just look at my bike. Black/Blue color scheme, shaved out aero look. It get's me out side and riding. Can't beat that!!! As far as the dealer? Originally I received a box with someones random stem replaced and the adjustable no where to be found. Though amazon I was quickly sent a replacement that got me up and riding within the week.

Minor modification needed, but otherwise, GREAT!!
I recently purchased the CXWXC Adjustable MTB 31.8mm 70 Degree - 145mm stem for my Aventon Level 2, and I must say, it has been a game-changer for my riding experience. This stem fit my bike with a minor modification, making it the perfect height to raise the handlebar almost 3 inches without the need to replace any wires. The installation process was relatively straightforward, with the only hiccup being the remounting of the headlight. The CXWXC mount where the existing light mount attaches was slightly larger, requiring me to make a small adjustment. I ended up cutting one of the mounting holes off the light mount to allow it to snug up to the new stem mount. To secure everything in place, I used two of the original short bolts to attach the handlebar to the stem and one of the new long bolts to attach the light mount onto the 4th hole of the stem. Despite this minor inconvenience, the end result was well worth it. Overall, I am extremely satisfied with the CXWXC Adjustable MTB stem. It has provided me with the perfect height adjustment I needed while maintaining the integrity of my bike's existing components. If you're looking to upgrade your ride and enhance your comfort level, I highly recommend giving this stem a try.

Excellent adjustment for Lectric ebike
Got this for my Lectric X 2, to move the handle bars up and back a little bit. It was relatively easy to install with one problem. It needs a spacer for the stock handle bars to work. They did not include a spacer/adapter. I made one out of PVC pipe I found in my junk pile and it works no problem. It was my oversight. There are units with the adapter included out there. Overall a really nice upgrade I wish I had done sooner. Solves the handle bar problem with my Lectric X2.

Great product, would buy again

These are a real game changer for comfort.
Great Quality for the price. We used these on both our Heybike Ranger S ebikes. The stock handlebars were too straight , , too far away and you had to hunch over, no matter what you did with the seat adjustment. They may look a little goofy mounted under the original handle clamp, but I assure you they are a real game changer for comfort, adjustability and they fit the ebikes neck perfectly.

Impressively well built piece!
Due to a wrist injury, I could no longer tolerate the straight-forward 105mm bar riser on my mtn bike. This looked like a potential solution, so I ordered it. I didn't know what to expect, but it is a VERY sturdy, nicely-adjustable (with serrated engagement to prevent slippage or movement of your setting), good-looking part. It absolutely does the job and has no flex that I can notice. I have it set on the tallest possible orientation and it makes a world of difference. Installs in minutes. It's heavier than a hollow piece of aluminum, but is a huge bargain for this price. You will not be disappointed. Note: be sure you check/set your steering head play after install as you will likely remove the top cap on your steering stem during install.
