In my opinion, for leisure use, sure. But for daily commute to work - a hazard. You still will use the motorist lane. Sure we have bike lanes in blue but during peak traffic jam/daily commute, due to the speed and handling (never used one so maybe la..) is a hazard. Since it is motorised, I would say it is considered a motorcycle and therefore need to conform to regular motorist rules - signal indicators, brake lights, speed (can't be too slow even) etc.

If I lived nearer to my work place I think I might try using electric bike 😆

For now it is not mainstream. I've seen some white guys cycling after work during jam hours. Looks so dangerous... Motorists avoiding / he going slower than them. I would say why not give it a go and see if it works out for you. If not practical then can sell off the bike lol.. as for legality, this I am not sure but as I mentioned should conform to normal motorised transport rules.
