Tesco has up to 75% off toys at the moment, and while it's not 75% they also have reduced the Chillafish Bunzi 2 in 1 Balance Bike from £45 to £30, saving you £15. I have looked for it online, and the only other place I can find this particular brand of balance bike is still selling it for £46.99, so this seems a pretty good price for the Chillafish bike.
I've never actually heard of this brand of bike, but it does look pretty funky.
It's a two in one bike because you can apparently change it from the 3 wheel mode to a two-wheel mode when your child is ready. It removes the need for stabilisers, and lengthens the life of the product, for sure.
There's very little information about this balance bike, which is a bit frustrating, but I have managed to figure out that it's suitable from 12 months, which I assume means it's not really suitable for older toddlers as it will probably be too small. That said, reading the reviews, most people bought it for children around 2 years old, and they say it's the perfect size, so that's a good guide.
Most reviewers also say it's sturdy and robust, so another point in it's favour.
