How long have you had out of your E8000 motor so far bro?
is it a month already?
Its had 2 decent rides.How long have you had out of your E8000 motor so far bro?

This reminds me of the modern Kickstarter projects... a lot of hype and marketing to draw people in.
I don't think it's really about them taking anything seriously (or not).

Shimano has pretty much stuck with 4 year rotation when launching each new updated groupset level for years now. and with the E6000/7000 and 8000 ranges they still have most bases covered. I think folk here get too carried away and can't see the bigger picture because they're so wrapped up in EBIKES R AWESOMEness to even see it.
also have a think about just how many pricepoints, cycling styles, levels etc. shimano components do actually cover.
in the grand scheme of it premium high tech parts like Di2 and Ebike motors are still a pretty small share in the shear volume of product Shimano shift year on year..
I don't usually comment too often in Rob's main page article threads as I have a habit of being easily derailled so I'll STFU now. It's not like this bike even interests me
Unfortunately there is only so far you can go with reducing the weight of a motor whislt also having a usable amount of power. Ultimately heat still has to be dissipated, and we still want it to be well sealed for reliability. What would really revolutionise things would be a step in battery tech, but I still can't see that happening in ebikes for at least 3-4 years (even if there was one in the coming months it would be swallowed up by automotive and industrial uses before products like ebikes got a look in).
It's just a fad. 9/10 wouldnt even know why they would want one other than they look cool.A coil shock is now pointless in the mountains of Andora when half the Ebikers in Swinley seem to be craving them?
Things have certainly escalated here
No doubt.Yeah, cause fucking around with a shock pump and re-setting sag height after every big meal is waaaay less greif than undoing 2 bolts, winding a threaded collar and swapping a springa couple of times a year.
Air and coil both have their metitsand downsides mate.
Not all of us are clueless fashion victims with bottomless pockets.
Now where did I put my gucci manbag?
51v system is more efficient. Less heat and potentially higher draw rate. They use more cells to get higher voltage. 36v can use less cells for larger energy capacity in a given space.
Well fundamentally it means the Forestal pack has half the available energy of the Levo. Capacity in Wh = Pack Voltage X Capacity in Ah. That means the Forestal pack has a much lower capacity in Ah (~6.85Ah) than the Levo (~19.4Ah), but the higher voltage means the overall energy available is only 50% less.
Not sure all that is entirely accurate tbh. Assuming they have specced a lower Kv (Kv = unloaded RPM/Volt) motor because of the higher voltage pack, current draw will be less for the same output power not more. You are right that should make it more efficient though as less heat will be generated (reduced I2R losses). Some of that will be offset as brushless motors generally get less efficient as you lower the Kv, but I agree the overall drivetrain should be a smidegeon more efficient at 51V.
