I've been thinking about this. The restrictions on e-bikes are that the motor can't be more than 250 watts and it must cut out if the bike reaches 15 mph. We can forget the latter because being assisted to exceed 15 mph (other than by gravity) is not one of my ambitions.
So, no legal e-bike can have a boost of more than 250 watts. Mine has the 250 watt motor and the top assist level must therefore be 250 watts, same as the Aviemore bikes. My bike weighs about 13-14 kg according to the shop. I could do with losing a few kg but I'm not massive. Whatever advantages the Aviemore bikes have for off-road use (suspension, mountain bike tyres, stronger frames, bigger batteries), they're going to be heavier. Therefore, logically, they can't have more glorious spadefuls of assist than mine will have. (I wish I'd looked at the OS map and not missed the steep hill to test it.)
I was in Banff (the Canadian one) in June, but just for a couple of days on the way to the Rocky Mountain Express. It certainly has some mountains!
I'm pretty familiar with the scenery here, even not from the road because it's amazing the cart tracks you find yourself driving up to deliver election leaflets not to mention the Border rideouts I've done, but it will be interesting to see what it's like from that trail. I see it goes down the Fingland Burn, where I have definitely not been. (Even on the roads, I'm used to visitors sitting in my passenger seat mindlessly repeating the word "stunning" like a stuck record.)
