I saw a segment the other day that someone apparently did at 130km/h.

tbh ebike riders are not much of a problem on strava (that I’ve noticed anyway), I lose more crowns illegitimately to mtb riders coming home from the trails in the car and deliveroo moped twats in London using strava to keep track of their mileage. Anyway Strava thread is that way >>>
 
They make the batteries propriety which keeps them pricey.

There is nothing magical about the Shimano battery tech. They use 2500mAh Samsung (or very occasionally Murata) 18650 cells wired in banks of four. The Shimano BMS is very good at compensating for dead cells but the battery pack is generally useless once two or three have gone. The 18650s are very cheap on eBay and I've brought a 'dead' Shimano BT-E8010 back to life with $20 worth of new cells.
 
I don't pretend to be anything other than a not that fit middle-aged man, three years ago I bought a regular (analogue) mtb and started riding for the first time in nearly 30 years, loved being out in the countryside and exploring, but found the hills a bastard to such an extent that it put me off from going out as often as I wanted and I certainly couldn't go as far as I wanted. Today I took one hour and seventeen minutes to do a route which in January took me over 2.5 hours, I built up a proper sweat, was puffed out, but could easily go and do it again, so double the distance of what normally does me in, what's not to like? Oh yeah, the cost of the fucking bikes 😧
I’m a not that fit middle aged man myself, and I’m not that great at hills but I used to be much worse. It’s exercise, physical effort and if you keep at it you’ll get fitter and the hills will become easier. Not by pressing a fucking button.

Oh I get the appeal (although apparently they’re kind of shit for fitness above a base level).
I guess because the motor assist means you don’t do threshold efforts as much - unless the battery runs out and you’re at the bottom of a hill, now with a heavy bike.
 
Tbh I was wondering about that, but the assist only works up to 15mph on most so you can still get a good effort in by going flst out if you want.

Well there’s nothing but hills from my house as I live at the bottom of a valley, so it’s e-assist or nothing. Or pull yerself up by bootstraps lad, the sleaterkinney way :rolleyes:
 
My big worry re eBikes is the millions and millions of broken toxic batteries that will, due to lack of planning, end up in landfills.

The manufacturer takes them back and pays the postage. Supposedly the battery is good for at least 1000 charges (will be down to ~60% by then and you should replace), that’s nearly three years of daily, battery draining rides, so probably not going to see them littering the countryside and that.

I still think they will be a big issue. There are millions and millions of ebikes being sold. The manufacturers taking them back doesn't mean jack. We all know how shit and dodgy the rubbish industry is.
They will probably be shipped off to a poor country to pollute their ground water rather than ours.

But not everyone wants to thrash themselves up hills. Some just want to get out in the fresh air and explore. It’s not always a competition.

There’s literally no reason why you can’t. I could get on an eBike and still go out riding to the point where I puke, but I’d be able to keep up with some of the 350W ftp monsters from my club on the hills.

eBikes are brilliant. They open up cycling - with every health benefit it brings, mental and physical - to a whole new group of people.

Mining is probably more of a problem tbh. Afaik lithium batteries can be recycled, though relatively complicated. There are also ways their lifespan can be extended - having a bunch of fucked batteries in an array where capacity of an individual cell is less critical for example. Grid storage, stuff like that. But it is something that needs to be addressed and private Industry will and is fucking it up as usual.
 
I think on the fitness thing there are two separate arguments going on, which doesn’t really help. It is very clearly better for Bahnhof Strasse and millions of others to get out when they otherwise wouldn’t, and will certainly build at least some level of fitness. Probably decent fitness.

Where it gets more complicated is in improvements above an averagely fit person. The one study I read indicated that experienced mountain bikers went round a course at 94% of normal pace (or a heart rate level 10bpm lower), with less perceived exertion. That sounds good, but a lot of discussion at the moment is around the benefit of high intensity intervals... that loss of 10bpm means less time spent at very high intensity, and less time at threshold as sleaterkinney mentioned.

There are probably further complications to that - an experienced mountain biker as in the study is going to spend more time above the assist limit, they’re also going to be more able to ride technically at boosted speeds.

Clearly that side of things doesn’t matter to the vast majority of people, but I don’t think it’s particularly helpful to polarise between ‘they may not be as good for fitness’ and ‘you evil bastards, you don’t want people to ride bikes’.
 
As an example of the not so fit crowd, after the route I took yesterday I normally need a week to get back on
the bike. Well, I am now 12 miles in, 10 off road, and at the highest point in southwest Surrey...

And feeling good, two choices now, Hankley Common and head to home, another 10 miles off road, or push on from Hankley to Frensham and Tilford before pointing back towards home. It’s downhill from here to Hankley, only a very light rain, so will head for Frensham, will make 35 miles in all, the day after a 15 mile ride.

What model is it by the way?

How do you figure out your own capability? I mean at any point including mid ride I know roughly how far I can ride before I'm thoroughly fed up, and I have some idea of how this scales up if I ride regularly - what it would take to be able to do a 50 or 100 mile day. When the bike starts doing some of it for you, probably non-linearly, I think this would get complicated.
 
In an ideal world I would really like to have an eBike along with my current Ridgeback Tempest Hybrid. Finances and room in flat will not allow that sadly.

It’s quite hard to explain, it’s not really like the bike is doing some of it for you, if you stop peddling then the bike stops moving, all the e-assist does is takes the sting out, much of the time the motor isn’t running as once you go over 15mph it cuts out. Also if your cadence isn’t high enough it doesn’t kick in either. What it does do is where you’d normally get off and push cos the hill is too steep and long to ride up without the aid of a defibrillator, it gives you assistance that allows you to ride up, and whilst still puffing yourself out you are not wrecked so you can carry on and you don’t avoid the next hill.

So really you know when you’ve had enough in the same way as on a regular bike.

I got the thing on Tuesday, so far have been out Wednesday, Thursday and Friday and am about to go out now. This just didn’t happen with the analogue bike, the e-assist one is just such a pleasure to ride that I’m keen to ride it. Which I guess must be a good thing.
