I'm a big fan of the Scuttlebug Ride-On toys, purely because my toddler loves his, and right now you can get then for £14.50 at Asda George online. The yellow one and the white one are both listed as £29, but when you enter the promotional code TOY50 at the basket you get 50% off making them a bargain price.
As well as being super comfy and easy to manoeuvre for toddlers, Scuttlebugs are cleverly designed to fold down for storage. I'm also not sure how they manage to make something so sturdy so light as well. They are great for toddlers to practice steering and balancing before they move on to learning to peddle, and can be used both indoors and out.
My son is just two and uses his every single day, carrying it from room to room and whizzing round on it. He does have short legs (got those from me) so younger children than him would easily be able to use this as a foot to floor ride on, and the description says it is suitable from 12 months of age.
You can use the free click and collect from Asda stores or home delivery charges are from £2.95. Remember the TOY50 code to get the lower price!
