Well folks, wish me luck because...
I DID IT!!!!!
Found a 2019 Explore E+ 1 GTS with small frame size in Edmonton Alberta (I'm in Montreal, Quebec) and I just sent the dealer money to confirm the sale. He's packing the bike up and I'm trying to arrange shipping from him to me. It's MUCH MORE EXPENSIVE than I had imagined to ship, but because I don't have to pay provincial tax (only the GST), the end cost to me is not that much more than if I'd bought the bike here in Quebec (and had to pay the GST of 5% plus the Quebec tax of 9.5% on top of the new total (tax on tax!).
I wasn't happy with the 2020 Giant e-bike offerings... the top Explore model we'll have in North America is the Explore E+ 2 GTS, with lower quality components than the current E+ 1 and much lower than the 2020 E+ 1 available in other parts of the world. And the new FastRoad E+ EX Pro was interesting, but I didn't really want the wider tires or a bike without front suspension and I really didn't want the smaller 375w battery. So the 2019 Explore E+ 1 GTS really has everything I want, although it would have been nice to have the new 6-sensor technology. Plus I really wanted to have an e-bike for the rest of this riding season because winter comes quickly in Montreal.
And a shout out of thanks to @DaveMatthews for giving me the heads up about the bike's availability.
Congrats ! You made the right choice. Did the dealer agreed to ship the battery across the country?
