Bikes aren't cheap, but if one of your little rider is due an upgrade for his or her wheels before the summer ends then check out this deal at Tesco Direct - the 16" Urban Racers Kids' bike is just £14 right now, reduced from £50.
The stabilisers are detachable, and the steel frame measures 10.5" and has rigid steel forks and eye-catching graphics. It also comes with crash pads, chain guard, a caliper brake and a cushioned saddle.
Self-assembly is required but judging by the customer reviews, that's pretty straightforward.
Standard delivery will take 2-5 days and costs just £3.00, so that's £17 for this bike delivered. Alternatively you can opt for the click and collect service to pick your purchase up in store with no cost.
