A daredevil e-bike rider has been sent sprawling after he crashed in a busy cross city tunnel trying to cross a raised lane divider to reach a blocked-off exit ramp.
Sisters Kobi Klyde and Amy Macintosh filmed the rider - who was not wearing a helmet - inside the Eastern Distributor in Sydney around 9.30pm on Saturday.
The man, dressed in a lightweight pink shirt and light grey pants, was travelling in the left lane, heading south towards Sydney Airport
Perplexed by the bizarre sight Ms Macintosh began to film the man riding the e-bike on her phone.
'What are you doing brother?' she asked.
The man then crashed into the lane divider just seconds later, as he attempted to skip into the left lane towards the Bondi and Randwick exit.
The man then fell off the Uber-backed white and green Lime rental bike and landed heavily on the road.
A helmet which appeared to have been inside a basket located in front of the bicycle, was seen flying out as Ms Klyde and Ms Macintosh screamed in shock.

Moments earlier, the man was seen changing lanes inside the tunnel several times.
Ms Klyde, 26 said the man was briefly holding up traffic on the southbound lanes as he was pedalling the bicycle.
'I was very shocked he was in the tunnel because I knew it was illegal,' Ms Clyde told the Sydney Morning Herald.
Cycling on motorways and in toll tunnels is illegal in NSW with offenders facing a maximum $2,200 fine.
A spokesperson for Transurban told Daily Mail Australia they are aware of the incident after being notified the rider had entered the tunnel.
'After locating the cyclist, we closed a lane and dispatched our Incident Response personnel to assist. The cyclist was able to exit the tunnel before our team arrived,' the spokesperson said.
Last year, a food delivery worker was captured on CCTV footage riding a bicycle inside the M8 motorway as cars and trucks drove by.
He then brought traffic to an abrupt halt, as he made his way across several lanes into another part of the tunnel towards an exit.
Another cyclist was also caught riding in the M4 tunnel, after an incident response crew saw the man riding his bicycle on the wrong side of road against the traffic.
More than a 120 cyclists travelled on motorways and tunnels across Sydney between January and July last year.
The Eastern Distributor was the most used by cyclists and 11 have been spotted there since January, with most being food delivery drivers.
A spokesperson from Transport for NSW told Daily Mail there are several measures in place including road signs, which instruct bike riders not to enter tunnels and motorways.
'Most tunnels are not designed for bicycle use and are high-speed vehicle thoroughfares that do not have the infrastructure or provisions in place for cyclists or pedestrians,' the spokesperson said.
'Bike riders who are illegally using tunnels are placing themselves and others at risk of being seriously injured or killed.'
