Lumintrail Rear Mount Bike Kickstand Quick Adjust Height Bicycle Side Stand fits Most 24” 26” 28” 700c

Overall, this is a fantastic stand. I installed two of these on my kids' bikes. I've listed a lot of cons, but overall I'm perfectly happy.Pros:* Very positive action. It locks up and down nicely.* Solid stand, no flex.* Stand length adjustment is super easy.Cons:* Heavy. If you're an ultralight bike person, you're probably not looking for an add-on stand anyway.* Fiddly to install. Installation is easy, just a bit of a juggling act with the stand, the backing plate, the anti-mar plastic inserts, and three bolts. Takes a bit of coordination and careful torquing.* If you're not careful about installation and checking the installation, the anti-mar inserts can slip and you'll scratch your frame's paint.

I couldn't get the kind that fit behind the bottom bracket because a brake line is in the way so this was my only option. Unfortunately the bar it attaches to is slim and tapered on my bike. No matter how tight I make it, it's just not enough because it wants to rotate around the bar - and the bike will fall over.It's still useful... when I take my bike out of the car it holds it up okay for a minute or so but I have to be very careful that it's set up okay. Starting to feel like it's not worth the bother, though I don't like leaning the bike against the car, either.There is no way I could leave the bike propped up with this for any length of time, I'm pretty sure it would eventually fall over :/

I converted a mountain bike to an eBike and I immediately noticed that it was too heavy for the original mid-mound kickstand. This kickstand was the solution. Initially it wanted to rotate under the weight of the bike, and the slicker the surface the worse this was. However, I managed to fix this by adding some outdoor-rated mounting tape between the frame and the rubber pads that are sandwiched between the frame and the kickstand. This sort of worked, but then I noticed that if I would just tighten the screws a little over the course of a couple of days this eventually compressed the "sandwich" of softer material to the point that the kickstand would reliably hold up my bike. On a standard bike none of this would have been an issue. In fact, this is a great kickstand. It is easy to install, the length is easily adjustable with the push of a button, and it looks good too!

Worked great for the application. I used this on a aluminum hard-tail e-bike. It is very sturdy and adjustable, so it should work with most all ADULT bikes. I doubt this works with anything below a 26" wheel. It's really tall. But with today's 29'ers it makes sense it's so long. Easy to install, came with a gasket to protect the chainstay and can be adjusted without tools. I am thinking I am going to glue it in the length I need, because I don't trust this adjustment feature. I expect this will be adjusting itself in a few months... But for the cash it's a quality kickstand.

For the price, the overall quality seems good. Good appearance. Mounting it was a little tedious, trying to hold the parts together and position it just right. Due to a brake line and the shape of my chain stay (goes from oval to nearly round near the rear), I had to position the stand within a 2 inch area. I uniformly tightened the 3 bolts (VERY important) for the best chance for the clamp to hold. Because of the rubberized inserts "relaxing", the bolts lose a little torque so I needed to tighten them down little by little several times before I was OK with them. I'm sure the stand would still rotate a little if pushed on too hard but it seems to be holding under normal foot contact. If it does move I believe a single wrap of rubber tape stretched around the chain stay first would provide better grip for the inserts/clamp.The push button to adjust length is great but I suspect the wire clip that fits into a notch may not withstand the test of time. Most of the bikes weight is on that wire clip. Mine is adjusted about 1 1/4 inch out. If the wire clip broke the stand would collapse that amount. I'm not sure if the bike would fall or not. To stop a possible collapse, I suggest placing something inside the adjustable hollow "foot". A piece of round wooden dowel or anything strong enough, cut to correct length, would work. Even silicone sealant would work. Also, if the wire clip breaks, there's nothing to stop the foot from falling off. Again, silicone sealant or a strong epoxy could work but the stand would no longer be adjustable.One last idea, to minimize pressure on the wire clip, mount the stand so the bike is upright as possible and still be secure. As a side note, I DID mount my stand at first so the bike didn't lean much but my foot was too close to the stand. I had to re-position the clamp to move the stand inward even more. So the bike is a little more upright than I'd like but it will be secure.So much depends on YOUR bike. The shape and height of your chain stay, any cables in the way, even where you like to place your feet on your pedals. From what I've seen, this stand, because it expands to 17 inches, is the best chance to hold a larger mountain bike. I have a 2018 Specialized Rockhopper Sport 29er with a large frame. It measured about 12 1/4 inches from the ground to bottom of the chain stay. Just remember to uniformly tighten the 3 bolts, try to minimize pressure on the wire clip by mounting the stand to keep the bike more upright, consider a wrap of rubber tape if the clamp wants to slip, and "modifying" the adjustable foot as I described. I think if your chain stay is too round then rubber tape is your only hope of the clamp holding, and it still may not work. Measured with a precision tool, my chain stay, at my mounting point, was .68 of an inch wide and .86 of an inch high, so not truly oval but somewhat oval. I give 4 stars. Could potentially be more or less. Hard to say until some time passes. Hope this helps.

At first I did not like the "squeeze" it puts on the chain stay, but it does not seem to have bent it. You will need to re-tighten the bolts again and again for the first few weeks of use - but frankly this is a responsible approach to any bicycle add-on. Once you get that done, the kickstand is really pretty nice. I've got it on my son's hardtail mtn bike, and we actually left it on during a trail ride. No problem. The trail was rated "blue" and had some drops. The kickstand was never an issue. It is also very light, so I doubt the additional weight is an issue.In any case, we've used it pretty hard for about a month and it seems great. I can recommend the kickstand.
