    • Very strong, easy to assemble, gave me the height needed to end back pain.

I’ve had this on my Freesky Ranger Air for about 3 weeks now and it works great after getting it positioned properly on the bike. I ended up turning the handlebar bracket 180 degrees, positioning the bars closer to me. This actually made the extension a little shorter but still raised handlebars about 3 inches vs the 4 3/4” that these risers were purchased for. Between rotating the handlebar and the added 3” height it was just what I needed to sit comfortably with my back straight. (I am 6’ tall) I’ve read where it is not recommended to go over 5” above the original riser tube which makes sense because it would put to much strain on the stem. That said with this riser and turning the bars 180 degrees this was all that was needed to greatly improve the comfort of this e-bike! ... show more

    • Wish I had done this years ago - Lerway stem extender is great

Ever since I bought my DiamondBack Apex in 1995 (it was a high end bike in those days), the handlebars have been a little 'aggressive'. After I crashed and burned on a technical trail and separated my shoulder many years ago, I moved on to less challenging rides but the handlebars were still uncomfortable. 10 years ago I went to the local bike shop to see if there was a simple, inexpensive way to put a taller stem on the bike and they told me there wasn't. I don't know if this was liability-related, but turns out there is and the Lerway extender is it. A little different setup than most as I have only a single binder bolt (?) for the handlebars with my Tioga Alchemy headset. But the installation (very easy) is exactly as shown in the Robin's Testing Studio video found on the Amazon site. Also, other videos available on-line. I didn't use all of the adapter rings because using the full stack height was a little too much to completely insert the stem into the handlebars. I ended up using 2 1/2 rings which overall raised my bars about 3 1/4 inches - which was just about the perfect adjustment. Following the on-line instructions this is an easy install and doesn't require you to be a bike mechanic to do the job. Allen (hex) wrenches are included for the Lerway components. I did need a different allen wrench to loosen the binder bolt on my handlbars. The end result is a perfect riding position, and provides a lot of flexbility for your specific height adjustment. Looks good and was an extremely good value for the money. Sorry I didn't find this years ago. ... show more

    • Much cheaper than getting a new fork or riser bars
Much cheaper than getting a new fork or riser bars to make a more upright riding position. Install is easy, just make sure you have the spacer rings in the right spot to get the rise you want and to be able to tighten the one bolt so your fork bearing are corrected loaded. Great for most riding, but I would be cautious using this mountain biking, aggressive trail riding or the like. Also check the tightness of all the hardware before, during and after you first couple rides. ... show more

    • Best performance upgrade - a bargain at 3x the price
Review Image by JGB
I couldn’t find a bar with both rise and bend that were perfect. So I finally got this, and once I figured out how to seat the spacers at the bottom, and filled in spacers on top, fitted the stem, and put my favorite bar on, it’s insanely perfect. It just looks like another tube on a bike once you get used to it. Seat tube, fork tubes, frame tubes, steerer tube. Brings my 5” rise bar up to about stomach height, which is perfect for off-road trail riding. Not casual, slow, easy beginner trail riding. Full on moto BMX on the woods. Learn to counterlean and get a setup that gets your upper body weight off your bars. Easy install (though the spacers can be a puzzle possibly), very sturdy, simple component, good quality, and the absolute best upgrade for performance for the buck I’ve ever gotten. (The tracker bend bar cost $30.) ... show more

    • Easy Install, very well designed
Worked like a charm! Being a tall male, definitely needed this to modify the handlebar height to ride comfortably. Super simple install as well.
