I won't put him out by especially contacting him, since I have no interest in buying one - just a general interest.
My electric bike is pretty good, and has done thousands of kms now over almost 3 years, without a problem except a couple of flat tyres and now, worn out front brake pads.
I like the idea of electric scooters, but they're not for me.
One drawback that crossed my mind today while I was riding mine is that with pedals, you can easily assist the electric motor on hills etc at 30kph, but that's much harder on a scooter, since there are no gears.
The other drawback is that they're technically illegal here. I checked the rules again today and in NSW the law only covers power-assisted pedal cycles. A scooter comes under the legal definition of a moped and needs registration and a licensed rider, indicators, brake light, horn, etc. Not fair, but that's how it is here.
What about VIC? Different laws?
