Whether it’s Bosch or anything else they’re not on my list.

The Crafty was awesome but it leaves me cold at the same time. Some of the climbs it just destroys with ease but the effort is part of the pleasure

You are allowed to turn it down and put in more effort yourself! 🫢

Anyway... Pics...? What spec was it...?

to give the Crafty it's due, it really did impress at times.

The power was smooth, nice and smooth. It was also pretty damn quiet, even though i've got wonky ears these days, i was still impressed with the motor noise, or lack of it.
There was no motor rattle at all when descending... This both surprised and impressed me. No cable rattle either, just quiet.

The only area it fell down on was the perception of fitness/effort. Although i was achey yesterday, admittedly in slightly different areas.

If you’re riding with people on regular MTB’s when you’re on a full fat eBike, even in Eco you’re not going to get the same level of workout…

If you ride it solo, or with other people on full fat eMTB’s, you will be surprised just how hard you can work!

Yeah I don’t doubt that, well, I do a bit 😀

But I get your point.

Lots of Amflow/Avinox out this weekend but i was absolutely blown away by the ratio of MTB/E-MTB, i think it was about 10-10 in favour of E-MTBs. It was arguably skewed by the fact that the places we were at this weekend were pretty steep and climby, but i barely saw a MTB all weekend. Packs of Eebs hunting the trails seems pretty common now at anyhwere.

Much as i hated the concept of them e bikes have changed MTB - whilst every everyone says “it allows me to go further” , they generally don’t . They just go faster. It means you can go out when yo don’t really feel like it, it makes getting to the top of the Downs as breeze, it makes riding Surrey Hills far more accessible.
But they do wreck trails

I'm not sure that it's the actual power of them that wrecks trails, but more the fact there's 3X the number of people and they're all doing 3X the number of runs, so someone would hit Barry knows best maybe twice in a ride, but now between them and their new mates who didn't used to ride they're putting 12 runs down it... So trail wear deffo becomes higher.
But taken in it's own instance, i'm not sure bike 1, doing 1 run, is any worse on the trails.

It's totally changed the sport, i'd guess it's arguably more social now for many middle aged riders, i see them passing me on the hills, chatting shit like they're cruising (which they are of course) and enjoying it.... I can't argue/fault that in many ways.

It’s no of runs, the “aggression” of those runs - and the extra weight of the bike …

Must admit to enjoy chasing down the Eebs on the Friston trails on my hardtail. It's either that or pacing me to get a better time as I try to keep them in sight.

Depends on terrain. 15mph is a hell of a speed uphill.

Most Friston trails contour gently down, to help maintain speed, apart from the end of "Clint Eastwood" (for ages it was the trail with no name) which is nearly a mile long and the last 300m when you're blowing out of your @rse is uphill and it's a killer😂😂.

Seeing quite a few Avinox issues since the M2S has been released. A lot of it seems to be switching modes and cutting out which may be FW and Update related by the looks of it. But seeing quite a few with "new bike back in shop after 2 rides". Can't say i'm hugely shocked in this day and age, but it's a bit confusing at times isn't it.

Tell you what, since getting the Amflow, I am itching to get out on it, never had that feeling with the Whyte t140,

Genuinely feeling like the old Supermoto days (to an extent)

I bloody love the power of it

Extra weight of the bike is minimal when you consider the "system weight" of the bike and rider together, which is what is critical... Typical rider is say 85kg, typical regular bike is say 15kg, typical eBike is say 25kg...

So the rider on a regular bike is 100kg, but the rider on an eBIke is only 110kg... As far as trail damage goes, that is totally negligible...

The increased damage will come simply because of the number of runs...

Bosch gets an update to 120Nm for what it's worth...

https://www.bikeradar.com/news/bosch-pe ... e-update-2

Personally, I couldn't care less... Rarely use 85Nm, mine is usually in Tour+ mode which I've set to 70Nm and even then the way I pedal, I'm rarely accessing that much torque even...

But then the power is put down through tyres more aggressively. And that before we get 1500 watt Avinox motors

Highway engineering describes road damage as a 'fourth power law' ie road damage increases to the 4th power for an increase in axle weight of vehicle. So a 10x heavier vehicle causes 10000x as much damage.

Can't imagine bicycles on tracks are immune so a few % increase in weight is likely to have a measurable effect on trail wear - alongside putting the extra power down through that small rear wheel contact patch and the additional trail usage.
The plural of 'anecdote' is not 'data'.
