Bought my 9 year old grandson a bMX nitro circus bike it lasted 4 months before the wheel became wobbly took it back to Halfords Sutton in Ashfield who said a bmx bike shouldn't be used for jumps tricks or Ramps! And so we had voided our warranty even though the frame was distorted which should be covered! I had previously researched this bike which you can buy a ramp for in the same name! After speaking to customer services for Halfords and screen shotting their messages they stated the bike was 100% perfect for ramps and tricks and that the frame should be covered under warranty. After several weeks of going round in circles with customer service advisors who never get back to you I'm still no further forward with a £200 bike that's worth nothing more than scrap. Have elevated the complaint but still no joy. Disgusting service and bad information on products if I'd have known a BMX wasn't any good for ramps etc (like the advice given) I wouldn't have wasted my money I'm expecting a full refund in due course as this product isn't fit for purpose and customer care by Halfords is some of the worst I've experienced! Still no refund or replacement and no reply despite several attempts to contact via email snd customer service advisors
