I'll make the popcorn.
Here is the ride if you want to take a look, The "long segment" i posted is tight single track, the short segment is open double track. Most of the climb is open double track.How long was the climb, and how steep was it? And was it tight, or pretty open? I assume this was in turbo mode? Or... whatever they call "full power output" mode?
We just had our first Tony experience a few weeks back. Had a fairly steep and long road climb to get to the trail. We weren't exactly pushing to get to the top but Tony came whirring by us like we were walking. My son was like what the HECK!! He was out of sight when we got to the trail but we caught him pretty fast once in the woods. He looked back and tried to get away from us and quickly ran off the trail and hit a tree. So bike skills still count for something, sometimes. A good and fit rider on an E bike will walk away from about anyone though. We see a couple of brothers in their 70's on e-bikes out in our usual trails quite often. Great guys and both have said they would have had to quit riding without the e bikes so I'm happy they are able to still ride. If it comes down to not being able to ride there will be one in my garage. Not just yet though.No surprise here, except the actual differences in climb speed are even greater than I expected. But when Tony Tubalinksi cooks past me on the uphills with his pasty breadbasket poking out from under his shirt, it is immediately obvious that it isn't a matter of fitness. Curious to see the responses, my experience is that there is a pretty good contingent of attack dogs in this forum. If it were me, I'd just shrug and say 'Thats the way I like to do it, its fun and sucks less". Popcorn in hand...
Anecdotally, my local trail system is pretty contested in terms of mountain biker access (with user groups that are actively trying to remove bikers, getting editorials in the local newspaper, etc). And at the local meeting with the parks dept, the speed differential when climbing was called out as a concern for hikers, specifically for ebikes (ebikes are illegal here). Mountain bikers are faster than hikers on the climbs as well, but not as dramatically fast (most climb ~3-6mph-ish). But the ebikes are 2-3x that, and apparently they don't like getting passed at those speeds.Is climbing at 12mph vs 4 or 5 or whatever really a safety issue? As you showed, going downhill, where a faster bike might be an issue or dangerous, the speeds are the same. And on flatter singletrack, THIS is where you will go a bit faster but not enough to be dangerous except in the wrong hands, like any other bike.
Again, what is so bad about going 2-3 times faster uphill? I can guarantee you there are some fast locals (maybe pros) that can ride uphill 2-3 times as fast as you, are they dangerous? I just don't get the whole list of your post...
