We've owned this from new, around 2.5 yrs. It is 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.
