That's mostly pretty good but the battery just kills it. 720wh @ 4.1kg is just not cutting it in 2026/27 I'm afraid. Look at what Gobao will be able to offer for comparison.
Seems as though a lot of brands will be going with their own proprietary battery, so I don't think the OE battery is an issue really. Otherwise I think it's probably exactly what most people need from a motor, even if it's not what most people want.
Wasn't one of the issues with the original EP8 system the fact that it was open standard? Rather than put in good batteries, brands would put in whatever battery met their budget/design that were either too small, too heavy, or too failure prone. Then if there was a failure with the battery, you basically had to hope that the bike company bought extras because Shimano sure as hell wasn't going to help you get a 3rd party battery.

YT comes to mind with that. Used market went bonkers there for a bit, riders buy used bikes just for the battery and <edit > wiring </edit > stuff.

Good luck to whoever buys a non-Shimano battery. Do we really trust the bike companies to put in something that will last, be supported with replacement parts and not catch fire?

Yeah, not really. If a proper battery maker is engineering it for the bike company, and the battery has the proper certifications, then I'm less concerned about the quality, but the warranty thing is really fully on the bike company's shoulders, and at least a subset of them don't seem to be taking proper responsibility for it.
There is the slow replacement issue, and then the lack of long term support issue. On the long term side: Santa Cruz is known for their awesome frame warranty. Lifetime bearing replacements. Etc...I know people who broke a SC front or rear triangle on bikes that were near 10yrs old, discontinued, and due to the lack of spare parts, SC gave them the newest current equivalent. Now, SC ebike parts only have a 2yr warranty, from my understanding. I am not sure if there is any obligation for them to make parts available beyond the warranty period, but if not, you could have a nearly new SC that is basically unusable due to a bad battery pack. Unlike with a frame failure, they will presumably not be giving you a new Bosch Bullit to replace the unusable Shimano Bullit, in this scenario, so it basically removes the incentive to buy a "premium" brand, because it shares the same weakest link as a budget brand like YT.
All of that assumes that SC doesn't have a warehouse of Darfon batteries and Fazua motors, to keep people on previous generation bikes going, and isn't handing out free warranty Bosch bikes. If they do, then props to them.
Cotic Bikes mentioned in the PB comments that Shimano has new batteries with 205Wh/kg density coming in February. Seems like a PR blunder not to get that out there at launch.

The open system also allowed for innovative/light bikes like the Orbea Rise and others which was a success. I never heard to there being issues for the owners replacing batteries. But that's a general thing with ebikes: we always talk about the latest and greatest and the evolution is fast. So nobody really cares if 5 to 10 year old bikes still can get spare parts.
