How would a deregulated e bike doing 25mph be any different to a Strava Hero hitting a walker or horse rider on a descent? I see lots of people posting GoPro videos and they don’t even slow down a bit when passing people, which must be pretty terrifying.
It also amazes me that some people think that mountain biking is just about fitness. Of course it can be if you want it to be, but there’s plenty of styles of biking that don’t require much. And I imagine the majority people usually endure the climbs to get to the downhills.
Mountain biking isn’t my main way of keeping fit, so if I want to do a long or hilly ride then I have to take it easier in other forms of exercise through the week (gym/ running etc). The fitness is a by product for me, not the main reason to bike.
I don’t have an e-bike yet but I will probably end up with one.
