So far, it is excellent
Color: Black
Size: 18”-28”
So far, so good. Seems very sturdy and well made. My bike is 36 pounds and seems so far to be working well for my needs. Attaches in seconds with no issues. Due to the set up of my bike, I had to install it the opposite way than what is in the pictures on the listing. I have the yoke end attached under my seat and the U end under the handle bars - works perfectly! Certainly easy enough to put on and take off each time if needed, but I think I will just leave it on all the time.

The best for this price

The product does what advertise but is not as fancy or flashy to the ones costing a lot more. In this case, the product came without a a bolt but was an easy fix. Its doing the job very well

This bar makes a nice support helping to keep the bike level. It is spring loaded to keep it snug.

Carry Girls bike level.

Sturdy functional. Logical to use. Heavy duty spring loaded operation. Intuitive to use. My wife has a front basket and this still works. Solves the problem of safely carrying girls (aka XX possessing people) bikes.
