    Well designed and engineered, great for a 29r Mountain Bike

    5/5 bluffwalker (Wisconsin, USA) - See all my reviews Verified Purchase(What's this?) This review is from: BV Adjustable Bicycle Bike Kickstand with Concealed Spring-Loaded Latch, for 24-29 Inch Bicycles (Sports) In the past, kickstands on my bikes have been little more than simple metal rods. I am pleased that this one boasts design elements that improve its function and appearance. The stand has the right curves and rotating parts to be out of the way when it’s up and to provide level support when it’s down. The stand has a nice click mechanism when moved from one position to another. The adjustable height creates a perfect fit for my 29r bike. The only installation annoyance was that the provided lock washer was too soft, causing it to open up like a “C” and falling off when I tightened the bolt. I easily replaced the washer with one made of harder steel. Two photos attached of the stand on my red Diamondback Overdrive MB., December 26, 2013

    The Best Kickstand, No Exceptions

    Edit: I just went to the hardware store to buy another longer bolt to fit this kickstand to a different bike. It was a 3/8-16 bolt. I used a 2.5" bolt for the new bike, since the included ones were not long enough.Prior to buying this kickstand, I was never really satisfied with the generic kickstands sold with bikes. They tended to be either too tall or too short with no real way to adjust them. Changing tires (from a rugged tire to a street slick) would alter the height of the bike, thus making the generic kickstand unstable.This kickstand is really amazing. First off, it is relatively light weight at 0.66 pounds total. Most other sturdy stands weigh double that, if not more. Second, the adjustability is super easy. Press a tab, move the adjustable section to the desired height, and set. No bolts or complicated mechanisms.Another selling point to me was the length. This will fit 24" wheels up to 29" wheels. The kickstand easily fit my... 5/5 Dylan Pitcairn (Seattle, Washington) - See all my reviews Verified Purchase(What's this?)

This review is from: BV Adjustable Bicycle Bike Kickstand with Concealed Spring-Loaded Latch, for 24-29 Inch Bicycles (Sports) This is a very study and adjustable kickstand that stays clear of the petals. I was concerned that given it's adjustable nature it would slip out of position but the adjustments firmly lock into place.Also, it is installed on a Diamondback Sorrento bike with 27.5 inch wheels so no problem with bigger wheel sizes.

    Much cheaper than a gym membership!

    Great little bike, I bought this to help strengthen my knee after ACL knee surgery over the winter and have been using it daily for the past 4 days. Much cheaper than a $40 monthly gym membership and so far it seems sturdy and easy to do first thing in the morning or in the evenings while I watch TV. Takes up very little space, don't really even need to fold it up. Took about an hour and a half to assemble by myself with the included wrench and tool. Directions were ok but first two steps did not have text directions like the rest of the steps for some reason. Other reviews were not positive on the computer part, but it works fine for me to track time, distance & calories. The seat is nice and padded with memory foam. Wish the backrest was the same but it is not uncomfortable. Pedals could be a touch larger and covers would be a good addition. Overall, great buy. Highly recommend if you want to own your own bike to use in the comfort of your own home and not have to worry about... 5/5 Bike chic - See all my reviews Verified Purchase(What's this?)

    A great purchase!

    5/5 Wes D - See all my reviews Verified Purchase(What's this?) This review is from: Ancheer Folding Recumbent Exercise Bike, Indoor Cycling Bike-Seat Height Adjustable, 5 tension levels, Calories Tracking (Misc.) I was a little reluctant to buy something like this online, but after my last exercise machine died, my shrinking belt made it clear that I needed to replace it quickly.I am really glad I got this one -- it's the perfect exercise bike for me, because of a couple of key characteristics.First, it folds up, and in its compact state, takes up very little room.Second, there is nothing to obstruct my view of the TV. Since the only way I can overcome the tedium of exercise is to work out while playing Xbox, this is an important one.Lastly, the seat is comfortable, even over longer (~90 min) periods of time. It is also easy to adjust for people of different height.I can't speak for everyone, but this machine is ideal for me, and I am very pleased with my purchase., November 1, 2016

    Bought this a couple of months ago based on the high rating and good reviews. Have taken the bike out approximately ten times since installing this kickstand. The way you adjust the kickstand is by pressing in the red plastic button that you see in the picture of the product. This causes a wire spring that wraps around the back of the kickstand to move out of a notch behind the kickstand, thus allowing you to extend or shorten the kickstand. Once you let go of the button, the wire slips into the notch for whatever new length you chose, and that is supposed to keep it in place.Today, I discovered that the plastic red button has fallen off somewhere. This means that there is nothing holding the wire in place, and the wire now slips out of its notch very easily. The first time I noticed the button was gone was when the bike started to fall over, because the kickstand had slipped down and extended itself too far.It's a sharp looking product, and I was initially... 1/5 Amazon Customer (Atlanta, GA United States) - See all my reviews Verified Purchase(What's this?)

    Acceptable replacement

    4/5 John Ruhl - See all my reviews Verified Purchase(What's this?) This review is from: BV Rugged Adjustable Kickstand for Heavier Bicycles with Spring-Loaded Latch (Sports) Does the job. A little clunkier and not as sleek as the original that came on my Schwinn mountain bike, but an adjustable kickstand is a functional compromise. It's easy to adjust to the perfect height, and I am confident it will last a long time. I had to install it with the mounting clamp at a slight angle to avoid interference with the rotating pedal arm, but it's not noticeable and is securely mounted. A good value.

I got just that! Installation took seconds and they fit will around two mountain bike flat bars.I will say I didn't buy these to light up a trail or to ride on the road with. I bought them in case I ever get delayed on an evening ride and needed some front and rear flashing lights to make others aware. These are brighter than I expected, and when I tested them in my garage with the lights off they were very noticeable. Will bike with that additional piece of mind now and will probably buy more in the near future. Help other customers find the most helpful reviews  Was this review helpful to you? , May 13, 2017
