Worked well on my bike

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

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

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.

Line up the bolt with the spring. I miss this step the first time. It was a duh moment.
Fits like it should. Holds the bike well.

Works well...
A little tricky to put together but feels sturdy enough and pretty easy to use . I've hauled my 64lb e bike several trips on my bike rack with no issues. Definitely good for the price.

Works as promised.
Works as promised. Took my daughter's bicycle to Jabel Hafeet top all the way from Abu Dhabi. As it was the first trip, was a bit concerned initially, but started gaining confidence day by day.. it's very strong and useful bar for transporting step-through bicycles.

Awesome
Well packaged by the manufacturer. Used it on a number of occasions and not had any issues. Looks like it will withstand the test of time. The only thing you need to be careful of is, when taking it off, remember it is spring loaded so when it returns to its default size I always catch my finger where they meet.

Great job 👏🏻
Great for holding up my Doris’s bike off the ground. Coupled with a wall mounted hanger, it works great 😊 It’s the little things that matter and because I explained in short sentences just how good it was, how I expertly fitted it and without it, the idea of supporting the Doris bike up high, I got a well done and a cake 🎂

Lightweight and fits most bicycles, not for e-bikes.
Very useful for transporting bicycles without a straight cross-bar as with most kids and adult bikes these days that are gender-neutral. I added a small rubber tube on the pin to prevent bike rash but other than that very robust quality and should easily withstand weight of around 20kgs. Easy to attach and detach, I bought 2 and have been using them for several months without any issues. The ends are all rubberised and can stretch out to fit most bicycles, just not e-bikes too heavy.
