I have my sons old Weeride Kangaroo for sale.
Used, but excellent condition. In original box. Will suit kids aged 1-3 1/2 maybe 4, depending on size.
It’ll fit on a full sus, which is partly why I got it originally. Kids love it as they can hold the bars and see where you are going! My lad did the gear changes for me 😉
Seat is removable, leaving just the frame bar, although this is heavy, you can leave that on permanently for speedy fitting (I didnt).
Very secure and cheapest I can see new is £65 from Asda: WeeRide
