Although, engines are a little different in that they tend to last the life of the car. EMTB motors certainly don't! There are also a lot more bike frame manufacturers than cars, which could make it commercially viable, for the frame manufacturers anyway.

I expect they're exactly the same unfortunately. I can't see them having made any improvements recently to them given they're now effectively obsolete. It's quite possible they're just old stock as well and no longer manufactured.

Absolutely. I can't see it happening though unfortunately. Frankly, even the ability to easily buy replacement motors I'd be happy with.

I can't see it, at least not that would be compatible with the existing systems. Shimano had a track record of not allowing backwards compatibility and forcing users to but a whole new system.

I thought I had one fail, but it turned out to be thr magnet had rotated ever so slightly and that was enough to give an intermittent fault. I've never tested it, but not sure they should have continuity through as would either be s Reed or Hall effect sensor?

I guess that's what makes them the money though. Unfortunately they're businesses so have to make a profit.

Front tyre still looks in decent nick. I could do with a new one as well, wonder if the owners selling?

Unfortunately I gave up on it ages ago. I got bored of what I thought were just biased adverts for their sponsors. A great shame as it has a lot of potential, and should be a growing market.

It's normally determined by the battery capacity (or lack of) and the internal resistance which limits the amount of current which the battery can supply and so the motor output power. Its very likely that the battery capacity will have reduced to the point where it isn't usable first though...

Wireless and safety critical applications..... only ever ends well!

I've been trying to be consistent and using only miles in the tables. Where people have stated km, I've converted to miles. There are a few oddities where there are photos showing km, but the system has been modified so its actually in miles! In the UK, we still tend to talk about distance in...

And table updated as I'd missed a couple over the last page. Some staggering mileages on bikes & motors.

Agreed. A good idea, but would probably be better in another thread.

Sorry, but is this correct? Lithium cells will always be charged to a fixed voltage to be 'full'. I think this table is about the maximum charge voltage and the associated resultant capacity relative to the what is deemed a 100% charge voltage which is normally 4.2V/cell, hence 42V for a 10S...

Ah, perfect, thanks.

Well, bugger. My E7000 is playing up so was going to get the shop to swap it out. Bit of a pain if the new motor then can't be derestricted. Will there be a work around do you think?

What ever decision you make, please ensure it doesn't involve keeping that bike!

Unfortunately the problem is proving it to get the warranty honored. Its a well known issue for some of the shimano batteries but they just ignore the claims. I tried to get a battery warranted but the software the LBS has had the capability removed by shimano to even read it out. They then...

You do of course have to prove the degradation to them to be actually able to claim the wattanty... I'd say 60% at 1000 cycles is probably about right though based on phone batteries.

300 before the battery's done? I've got just over 200 on one of my batteries and it's lost about 20% of its capacity now, although the degradation seems to have leveled off.
