You don't always expect a guy in his 70s to be able to cycle up a notoriously steep road for a beer at a popular pub.
But that's just what one of the customers of Riding for Life e-bike shop managed to do, according to owner Andrew Larkham.
"I had a guy - he was about 71 - he bought a bike here and the next day he rang me," Mr Larkham said.
"He was sitting up at Mt Kembla pub having a beer. He said 'Andrew, I can't believe it. I rode up the hill and I'm sitting here having a beer. I absolutely love it'."
Mr Larkham said he knew that feeling - he opened up his Wollongong store 10 months ago after test-riding an e-bike in January.
"You get your moderate exercise but you can ride longer, you can ride further and you arrive fresher when you do arrive," he said.
"The biggest advantage for an e-bike is riding along and you come to a hill where typically, a rider will be absolutely killing themselves to get up the hill. Instead, you just whack it it up a couple of modes - you've still got to pedal but once you get up the hill you still feel fresh."
The legality of e-bikes and e-scooters has been a talking point on social media in the lead-up to Christmas, with NSW Police posting reminders of the sometimes severe restrictions around them.
For an e-bike, the pedals still have to be the primary power source and, if the motor is used, the bike cannot travel faster that 25km/h.
A bike that doesn't comply cannot be ridden on public roads, footpaths or cycleways. Those caught doing so risk a fine starting at $704.
As for electric scooters - and skateboards and hoverboards - they are illegal to ride on public property in NSW.
Mr Larkham also sells e-scooters and said he always informs potential buyers of that restriction. However, he thought that law should be changed.
"I think the e-scooter law is probably a little bit silly," he said.
"They're legal in Queensland, they're legal in Canberra and I think NSW needs to look at what the other states are doing."
That seems to be what the NSW government has in mind, with a trial of e-scooters due to start next year.
"This trial is in response to growing popularity and the need to safely manage their use," a Transport for NSW spokeswoman said.
"The e-scooter trial will provide Transport for NSW with data about how e-scooters are being used, how they can support mobility outcomes and important insights into safety risks and how to manage them."
The spokeswoman said the potential for e-scooters to "provide an affordable, convenient and sustainable mode of mobility" needed to be balanced against "the known risks of e-scooters to users and pedestrians".
