Not for Strider bikes

1 Star only because it does not fit the Strider Balance bike. The axle size is different and the wheel is too tall. It however is a nice, light wheel.

I am disabled and bought these for my 24" bike. They do not fit the frame.  By the time I had someone help me put them on, it was pass return period.  Now I am afraid to try another type for fear that I will be out more money.

I bought this lock to use on my 2011 Harley Davidson Dyna Super Glide, however it will not work due to the diameter of the locking pin.  Apparently, the diameter of the holes in a stock Harley&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Kryptonite-998655-Yellow-DFS-10-Disc-Lock/dp/B0030M4DCQ/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Kryptonite 998655 Yellow DFS-10 Disc Lock</a>disc brake are smaller than that of the Kryptonite.  Makes a great (expensive) paper weight, but basically useless for the intended application

Would not tighten on my Trek bike.  In fact the metal screw scrapped some of my paint off.  The design is clearly made for smaller handle bars, not my 3mm handlebars.  Sent it back. Very unhappy.

Simply does not fit at all on my Giant Roam 1 bike's handle bar. The supplied clamp/screws are too small. Ended up being completely useless.

The clamps, although they come with a soft rubber layer on the inside, they have sharp exposed edges that caused scratches on the handle of my bike when I attempted to install them (unsuccessfully).

I read lots of reviews and purchased this hoping to finally exercise at home.  I had eye problems and could not ride my bike in the neighborhood any longer.  Unfortunately, this stand does not fit my newer bike that has the easy take off wheel.  I had not read this in the description that it would not work.  I tried returning the item, but due to health issues, it was a little over 30 days.  Again, unfortunately the seller told me I had waited to late and would only refund $8 and just give it to someone else.  Bummer.

Not for professional arca Swiss clamps. Should of looked at pics. Has the stoppers

As others stated, does not fit many of the bikes it is listed as being compatible with. If you're okay with drilling out the mounting holes for a sprocket (dumb for a few reasons) then good luck...

It states universal but the holes were too big for the exercise bike so I had to rig things differently

The clips will not fit a slandered pedal (my case trek 4300) unless you modify the slot. I had to use a soldering gun to enlarge the slot before I could install them on my bike

These training wheels do not fit a 12 in. bike.  One end of the bracket is adjustable and according to the directions should attach to the bicycle wheel.  However, the bolt in the middle of the wheel was too large and the only way to install results in the back end of the bike being lifted off the ground.  I did email the seller and they did reply to my first email.  However, they did not believe that the training wheels wouldn't work.  The wheels themselves seemed to be of good quality and they may work fine on a 16 in. bike.

The quality of the bar and the chain appear to be good, but be advised that this bar will not fit Stihl chainsaws.  I bought this as a short bar alternative for my 18" 024AV Woodboss.  The pitch is right, the groove width is right, but the position of the adjuster to the bar guides is wrong and will not allow the chain to go around the clutch.  I bought a Stihl 16" chain to make sure that this was not just a short chain and the exact same problem.  Looking at the OEM Stihl bars, it looks like this was intended for Husvarnqa or Homelite. Stihl bars don't have the open mounting guides.

This was deceiving. The housing cables have the spiral wound inner wire support, instead of the lengthwise kind you would find on any new bike with modern shimano or sram shifting. This isn't compatible with the new stuff, even though it says SIS on it.

Did not fit on either bike I own. The front attached to the a part of the handlebars that has to be able to move so the seat was not secure.

It does't fit my Bike properly, had to trim the leavers, it is probably the bike's fault.

Product advertised to fit 2015 883 sportster, and it doesn't. Only the right hand extension fits. The left side is completely wrong and cannot work on my bike. False advertising.
