Satori UP2+ - E Bike - Bicycle Riser Extension Adjustable Handlebar Stem 1-1/8" x 31.8mm x 65mm/90mm/110mm - Great for E Bike Up to 45 km or 28 Miles per Hour - 3D Forged Alloy - Super Heavy Duty

Very easy to install and made though

Seems like good quality. This is supposed to be the more heavy duty version for ebikes and mountain. That is the difference versus the Up 3 model. One of the adjustment bolts was really torqued tight. Just keep turning, trying not to strip it. Definitely follow the steps in the video for fast and correct installation.

I purchased this riser to install on my Aventon Aventure ebike. It fits perfect and feels solid, important for this heavy, fat tire ebike. It was easy to install. One consideration - if you have the front rack installed, there may not be enough play in some of the cables/hoses to allow for a riser stem. I installed the 90mm version, similar to the OE size, but when elevated, some cables were tight and the Tektro front brake hose was a constraint. I removed the front rack to allow for proper clearance. I saw another review that showed the stem with the front rack installed. May depend on the components your bike is built with based on availability. This concern is not specific to this product. Raising the bars definitely takes pressure off of the hands/wrists/elbows and makes the riding position more comfortable. This product is a good way to do it.

Wife rides a stock Rad Rover e-bike. She complains that the handlebar is a bit low and has her reaching a bit, increasing the weight on her wrists because she is leaning forward. I like that the pivot mechanism on the Satori stem seems more robust than most that rely on one nut and bolt to secure the pivot. Installation was painless, adjustment was easy and the small change in rise and a slight pullback in the new position resulted in her raving about the new comfortable position. Booyah! Recommended, just be vigilant about sizing. Watch some videos on stem replacement so you have some idea of the wrenching involved. Otherwise, go to a local bike shop and buy from them.

I purchased this stem riser to take pressure off my neck & shouders. I am 58 YO and been an avid cyclist since 1983. I ride higher end bikes and had a need to complain until 2021.This riser does a good job. BUT it is much heavier than I could have imagined. At this point in my life, comfort supercedes weight as I could lose 20 lbs and make up the difference this adds to my ride. With this said, it is a well built piece of metal. The adjustabiity is endless and the install is straight forward (DO NOT overtighten the head bolt into the fork).

It is designed quite well, it’s sturdy, solidly mounts and is more adjustable than most all others, which gave me the right fit for a more comfortable ride.. (If you have play in the fork after installing, you most likely need to adjust the stem spacers.)

This product is easy to install and works well on my e-bike (KBO). Helps bring the steering to a comfortable level. I’m baffled why bicycle manufacturers don’t install these from the beginning. Every biker I’ve spoken to purchases one of these.

Easy to install and setup.

This stem requires two bolts to adjust and is not like others that are a simple loosen one bolt and tighten in position. This was not simple.

The media could not be loaded.  Excellent produit j’en ai commandé d’autres pour les vélos des membres de ma famille !! Satori toujours un excellent rapport qualité prix !! Je le recommande.

Want to share for others in my situation (as I researched this a lot) that I turned it the opposite way to the images/videos in order to bring my RadRover 6 Plus e-bike's handlebars closer and higher to my body as I'm 5'4 and the reach was a bit uncomfortable for me. Worked perfectly, the handlebars are much closer so my arms aren't so stretched and I like the height options

I am over 6 ft tall and it Improved my ride and comfort .
