@Dolomite - e-lobbying across the big pond, eh?
I live in Southern Germany (and manage and build a legal trail system here) and I travel a lot with my mountain bike, all over Europe and have spent quite a bit of time in BC and North America as well, biking.
Just for the record, I disagree with several of your "conclusions" and "facts".
1. the Dolomites, parts of Austria and South Tyrol DONT have THE best trails in the world. There are great trails in these regions, but that is true for a lot of regions. I don´t know if you´ve ridden all regions world wide a lot, but if you don´t, you just can´t speak of "world´s best".
2. E-Bikes and trail access are absolutely not without trouble (in Europe) and I for example have certainly NOT understood the potential of E-Bikes the way you have. I however understand that there´s a boat load of POSSIBLE trouble.
3. As with guns, not E-bikes kill trails, but some people riding them ;-) I´ve experienced douchebag non-e-bike behaviour on trails over the last twenty years. And I´ve experienced douchebag e-bike behaviour on trails. If you have physical ability as a selecting factor (only dedicated people get to 6000ft mountain tops self propelled) there´s a humbling element. Lazy people just don´t go there a lot. And if you´ve climbed LOADS you just don´t argue. You sit there and nibble your energy bar and some water, content with little stuff.
Add a motor though and things get ugly. I KNOW - riding an e-bike can be very exhausting. And absolutely not everyone who rides one is lazy or a douchebag. In fact, there´s no reason that regular mtbers are douchebags, too. And in lift or shuttle assisted riding areas the douchebag factor is higher as well. But suddenly every "regular" tough climb is not as strenuous as before. You´ll have e-bikers speeding climbing trails. And some who don´t. But what´s the point of lugging 5kgs of motor and battery and NOT speed? You could just ride a regular bike...
Yeah - you can rack five times as much elevation a year with your e-bike. But know what? I could multiply that with my car. And could even do it in the rain, without getting wet. In fact - I could do it with a bike on my roof rack. =)
To be fair, as long as you ride your e-bike responsibly, I couldn´t care less if you ride e or non-e. Have fun and enjoy yourself. But just to give the Canadians here a second, non-e opinion I thought I´d contrast your pro-e-bike european opinion with a european non-e-opinion...
