Three teenagers have been injured – one seriously – in two separate crashes involving e-bikes.

The first crash involved a 14-year-old boy hitting a stationary car on the Five Islands Road Bridge, Teralba in the NSW Lake Macquarie region.

Police said the boy was treated at the scene by paramedics after the incident on Tuesday night at 7pm, before he was taken to hospital for further treatment.

The car’s driver, a 48-year-old man, was uninjured.

Police revealed they have seized the e-bike as they continue to investigate the crash.

Another crash involving a 13-year-old rider and his 11-year-old pillion passenger, was reported just 20 minutes later on the state’s south coast.

The pair were thrown off their bike and onto the road after striking a Toyota Corolla on Gloucester Circuit, Albion Park at 7.20pm.

Paramedics treated the 13-year-old boy before taking him to Wollongong Hospital. The 11-year-old pillion passenger suffered serious injuries and was flown to the Sydney Children’s Hospital in Randwick.

The 36-year-old Corolla driver was taken to Shellharbour Hospital for mandatory testing as police continue to investigate the cause of the crash.

It was revealed last week, a NSW crackdown on illegal e-bikes resulted in 68 bikes being seized in the past three months.

An operation in the NSW Hunter Region netted 10 of those bikes, with another 36 modified bikes seized across Sydney’s northern beaches.

Another 22 e-bikes were taken off young riders in Sydney’s south and the Illawarra last month, including in the Cronulla, Wollongong and Shellharbour regions.

War of words over new rules

The lastest crashes come as the Coalition ramps up its targeting of the Minns Government’s e-bike legislation.

Opposition transport spokeswoman Natalie Ward on Monday accused NSW Transport Minister John Graham of letting a key piece of new legislation “gather dust”.

“In February it was ‘there will be an age limit’ and now it’s ‘ask me after the election,” Ms Ward said.

“He is tough on talk and soft on delivery. It is a weak response that ignores the community and lets injuries pile up while the report he promised sits on his desk. Accountability for the public and riders is currently the emergency room yet nothing for the Minister.

“We have an implementation plan for license plates paired with education. John Graham has admitted he has nothing.”
