A potentially lethal batch of motorbike crash helmets which were on sale in the city have been seized by Peterborough Trading Standards.
The helmets, which were on sale for just £25, were so dangerous trading standards officers said it would be like not wearing head protection at all.
Now bikers are being warned to be aware of the risk of buying the cheap helmets on the internet.
Officers are urging anyone who has bought one to stop using it immediately and return it to their supplier. The helmets concerned are Jiekai model JK 100 or JK 1000.
Peter Stonely, Principal Trading Standards Officer, said: “As someone who does ride a motorcycle I am shocked by these results.
“They failed impact tests, being destroyed within two impacts, rather the full five it should take.
“This would give a rider almost no protection in a crash, increasing the chance of brain injury or death.
“They also failed a number of other tests.
“Wearing them would give the rider a sense of safety, which the helmet would not back up.
“You may as well not wear a helmet, they are that dangerous.”
It is believed the helmets were old stock transported from China and purchased on the internet.
Anyone who thinks they may have purchased one of the affected helmets should stop using it immediately.
Howard Anderson, director at the British Motorcycle Federation (BMF) said: “The question you have to ask is how much is your head worth? You should only use recognised brands and helmets that have passed a Sharp Test.
“You get what you pay for and you should get the best helmet you can afford. There are plenty of good solid helmets available at reasonable prices.
“Buying a helmet like this is like buying a deathwish.”
Trading Standards officers attended this weekend’s BMF show at the Peterborough Showground offering advice about helmet safety.
