My quinny buzz four which i bought off ebay a couple of weeks ago has today started collapsing when i go up kerbs mostly one side. Its fine going up and down (the hydrolics) and doesnt happen all the time but its quite scary ive been in touch with the person i bought it off but shes stating it was fine when i sent it. Im wondering if you know what could cause this and if i can get it repaired. thanks

I bought it and its great - much easier to push

SOURCE: Main frame and worn wheels of the quinny buzz

This happened to my wife the other day, I found that the main pivot bolt had pulled through the plastic pivot/collapse assembly. This part is rivoted to the frame so without drilling it out and replacing with an ugly nut and bolt you will have to source a new frame. I got mine from Ebay, I found someone selling lots of quinny buzz bits and asked if he still has the frame he said yes but the handle bar no longer extends (Hence im on here looking how to swap the two), Problem solved!

I also found out from Quinny that the Buzz has a 2 year manufacturers warranty, where Motercare insisted it was 1 year, so dont let them fob you off.
Hope this helps
Chris.
