We have been looking for a way to teach our son how to ride a bike. He is very tall and blew past the training wheel bikes incredibly fast. We tried to teach him without training wheels and there was just fear of falling. We installed these and they make the adult mountain bike pretty stable. It gives our kids confidence. There is only really one main diagram for the direction but installation was simple enough. I did feel that it was easier to prop the attachment on my leg while sitting on the ground to install; there may have been a more suitable position, but this worked for us. I was able to use my hands to screw on the bolts. During use we noticed that the tires came very flat and need air, as well - depending on size of biker, their foot can hit the aforementioned bolts when pedaling. Considering the circumstance, these were a great option, but it is no perfect.

Works good, very sturdy. I used it on an ebike so I had to modify it a little.

they are well built but may need some knowledge on how to install depending the bike frame you are putting them on . I think they could have better install instructions with the kit or online

Non compatible à divers types de vélos.

The hardware with this kit is absolute garbage. Do not buy this item
