Sydney sucks. I’m in Melbourne and the train leaves every 5 minutes, takes me about 20 minutes to get to the cbd about 7km away. Rent is pretty affordable too.
It's viable, but I think over all it's a little bit less convenient when you have to mess around with the bike, lights, helmet, etc. My place is about a 3 minute walk from the station so it's basically just step out the door and on to the train and then I'm there.
I don't mind riding my bike around to the nearby shops on the weekend but usually its just most convenient to get places on foot or by PT. I only really do it for fun and fitness rather than it being the fastest way to get around.
Seems like a bike or eBike would be a faster way to go? Melbourne climate is pretty temperate, no?
