    • Good and sturdy

Works great! Makes my 30yr old Trek MTB rideable again! Super easy to install. Build quality and fit were perfect.

    • This is perfect to make my HeyBike a Yay-bike.
Color: Black-210mm
Wow, who knew, this is what a tall person really needs with any bicycle. For an Ebike this makes its super comfortable. I purchased the 210MM, it was a snug install and I had to remove all the "clips" or other holders on the cables. Once installed, it was very smooth and no wiggly issues. This is a post, very simple to slap into place. Then the rings go on to achieve desired height, so you can remove them to go lower, but you always have to extend to the highest height to get the handle bar over the top. If you are unsure of how much length you can get out of your cables, order a shorter height. I was able to put this onto my Heybike Race Max 27.5", the best super cheap ebike right here on Amazon. ... show more

Looks Good and does what it should. I got the tall one, which gives me plenty of adustment, as to what height I want to install my stem.

Fit well on my older Scott 30 bike. Directions were not included and would have been helpful. Got directions off the internet.

    • Couldn't get it to work for me
Color: Black-210mm
3 days trying and I gave up trying to get it to work. Couldn't get the adjustment right. Either too loose or too tight, I think I'm pretty mechanical but this has me stumped. I'd think I got it then it would loosen up, after about 29 attempts to get it right I went back to the original and within 5 minutes my old one is set up perfectly. It's NOT me. ... show more
