We've owned this from new, around 2.5 yrs. It has been well used, but still perfect mechanically.
Adjustable suspension, easy to mount to any bike with QR rear wheel, and usable for a wide range of younger kids. We've used ours from about 4 months, and have only considered selling it as our twins are rather large and at 3 years old, are rather heavy to get up the big hill to our house!
2 x baby slings
2 x bike hitch with Q/R
Stroller/running kit (wheel + mount arms)
Due to the size of this, I would much prefer the buyer collects from Bolton area, or I can meet within reason. I am across in Sheffield for work most weeks, and also work a day or two in Nelson/Colne area, if that helps. Happy to answer questions on here, or else email is in profile.
