Two teenage boys killed when their petrol powered dirt bike slammed into a bus in Sydney‘s west had both shared a haunting final video of themselves riding the same bike together.

Adrian Lai, 15, and William Drake, 16, were zipping along the Liverpool Parramatta Transitway at Bossley Park when they collided with a bus at around 7.15pm on Monday.

The bike, which was being ridden in tandem, became wedged underneath the vehicle and both boys tragically died at the scene.

The pair had developed a keen interest in the sport and frequently shared clips to social media. William, who had only recently purchased the bike, shared the same footage as Adrian of them riding it before the accident.

In the clip, posted to TikTok, Adrian is seated behind William as they speed down a residential street before he performs a wheelie.

William is wearing a full face helmet with just shorts and a t-shirt, but Adrian does not appear to have protective clothing or a helmet.

Both boys also uploaded several other videos in their carousels, including a mirror selfie together and more clips of hair raising tricks.

Friends flooded social media with tributes, remembering the pair as fun-loving boys and passionate trail riders.

But news of the boys’ deaths, especially in the wake of growing calls for tougher laws around e-bikes, has also seen heartless comments directed at their grieving parents.

William Drake and Adrian Lai died on Monday when the motorcycle they were riding hit a bus 

Within hours, harrowing footage circulated on social media showing the motorcycle trapped beneath the front of the bus

‘Why were they out at dark on this bike?’ one person wrote.

‘Where were the parents?’

Another added: ‘How many lives need to be lost before something is done, why are the parents allowing them to have these bikes.’

The sparse comments were dwarfed by the amount of tributes for the popular boys.

One friend recalled seeing Adrian that same day and not knowing it was going to be the last time. ‘Rest in peace Adrian, one of the most funniest ones I knew,’ they said.

Another friend said: ‘William, never thought I’d lose you this early. Thank you for everything you taught me on the bike. I’d be nowhere near where I am without you.’

‘It’s a wake-up call to everyone – get rid of these bikes, they are not toys. It kills to know you’re gone and doesn’t feel real.’

William’s older brother, Byron Drake, also shared his grief, thanking a family friend for posting a tribute. ‘Thank you so much for this video you have posted for my little bro,’ he wrote.

The bike was wedged under the front of the bus 

Adrian often posted pictures of himself performing stunts on his bike 

Friends have since organised a memorial ride in honour of the boys, set to take place on April 3 at Bankstown Airport, urging those attending to ‘ride safe and respect the day.’

There was also an outpouring of concern for the driver of the bus, who was taken to hospital for mandatory testing.

‘That poor driver,’ said one person. ‘He was just trying to do his job.’

‘We need to spare a thought for the driver who has to live with this for the rest of his life, as well as the families who have lost their boys,’ added another.

Police said neither the driver nor any passengers on the bus at the time of the crash were injured.

While the teenagers were initially suspected to have been riding an e-bike, transport officials later said it is now believed to have been a petrol powered trail bike.

NSW Police Commissioner Mal Lanyon said it was a tragic scene that would impact many.

‘We’ve got two young boys who won’t grow up, we’ve got two families who will grieve forever at the loss of their loved ones,’ he told Radio 2GB.

Friends have organised a ride in memory of the teens 

The pair were riding tandem at the time of the crash 

‘Importantly as well, we’ll have a bus driver who will be significantly impacted, and for our first response officers, our emergency services who have to attend these scenes, they are incredibly difficult to go to.

‘So our thoughts are very much with the families and certainly those impacted.’

The crash came just hours after NSW Police revealed they had issued 170 fines during a two-day operation targeting illegal e-bikes in Sydney’s south last week.

Officers spoke to more than 215 e-bike and e-scooter riders last Wednesday and Thursday and issued a further 99 cautions.

‘More than 250 people were breath-tested and 26 people were drug-tested,’ police said in a statement on Monday morning.

‘There were five e-bike riders who tested positive to drugs.

‘Police laid five charges for criminal offences and 21 traffic charges.’

Traffic and Highway Patrol operations commander Anthony Boyd said officers take illegally modified e-bikes and dangerous riding seriously.

The tragedy comes as new laws allowing NSW Police and Transport for NSW to seize and crush illegally modified e-bikes are set to be introduced into parliament
