If you're going to ride your e-bike after hoisting a few drinks, be sure that you didn't take your pedals off.
That's one takeaway from a recent police scanner conversation related to me (the other takeaway is: don't cycle while impaired).
Apparently, the local police had detained a woman who was clearly impaired while riding her e-bike. After about 30 minutes of backing-and-forthing on the radio with someone else higher up the food chain about whether the woman could be charged with impaired driving, the detaining officer was told what I could have told him instantly: under the Canadian Criminal Code, impaired driving applies to the operation of "motor vehicles."
Under Ontario's Highway Traffic Act, an e-bike is a bicycle, despite having an electric motor. But that e-bike designation applies only as long as the bike meets the criteria for e-bikes. The most common modification for e-bike owners who plan only to use the electric assist motor, is to remove the pedals (which they say get in the way of their comfortable use of the e-bike).
Take off the pedals, and you don't have an e-bike: you essentially have a "motor vehicle" (because it is entirely dependent on the motor to move).
If the detained woman had removed her pedals, she'd be looking at a Criminal Code offence. Since the pedals were still on the bike, she's not chargeable for that offence.
There are likely other things the police could do: drunk and disorderly, if she was. No lights if travelling at night. Etc. But drunk driving? Uh-uh.
