The Warehouse is recalling 11 types of Milazo bikes

The 417 to 427 models have been sold at stores and on the company's website since April.

The crank arms, which are connected to the pedals, may be defective so could become loose and fall off.

If that happens, the rider may lose control of their bike and fall or crash.

People are being told to stop using the bicycles and return them to their nearest Warehouse store for refund, even if they don't have a receipt.
