I recently did some research into weight limits for e-MTBs. I compiled the table below based on published material in their websites or responses to my emails. The list is not every manufacturer, but simply the ones that I was looking at, or were available to me in Australia.
Almost all brands specify a max limit for an "All Up Weight" (rider, gear and bike). Rocky Mountain specified Max Rider Weight in their response.
I noted bikes are manufactured to an existing bike standard, ISO 4210 (which replaced EN 14781 (road bike) and EN 14766 (mountain bike) standards). This standard does not take into account e-mountain bikes with the added stress due to bike weight and speed.
As a result these bikes are usually only rated to that ISO standard, which is 120kg. Not that they cannot go beyond that in the real world, it is simply they have been manufactured to meet that standard and therefore they only guarantee to that standard.
A lot of people will state they ride beyond those weights without issue, which is fine until something breaks and then the manufacturer will not warranty it.
Some manufacturers are now pushing beyond that and I would suspect soon there will be a new standard for e-MTBs. You will note some manufacturers are already using components (forks etc) specifically rated for e-MBT.

It is these components that will raise the max rider weight limits of the bikes, not their frames. I am pretty sure the manufacturers can make quite strong frames, it is the off the shelf components that are added tot he frames (Wheels, shocks, forks, brakes etc.) that are subject to ISO 4210.
Assuming a 20-25kg bike weight (covering all bike sizes), you can subtract that from the listed weights below in the table to get the max rider weight. All except Rocky Mountain who specified a rider weight (rider/gear/clothes) of 136kg straight up, so technically a max all up weight of 161kg (136kg + 25kg)
So for the heavier riders I would look at Giant and Rocky Mountain if you are looking for a bike that will be covered under warranty without argument over the rider weight.
I hope this helps.
