According to Cycle World (surprised this wasn't picked up by the usual electric motorcycle sites):

https://www.cycleworld.com/story/motorcycle-news/can-am-new-electric-motorcycle/

[Nairb]

Now an announcement with renderings and video

https://news.brp.com/news-releases/news-release-details/brp-announces-return-can-am-motorcycle-all-electric-lineup

https://electrek.co/2022/03/25/can-am-announces-it-will-launch-two-new-electric-motorcycles-for-on-and-off-road-riding/

coming in 2024

This item isn't going to do what is going on at the begining of the video.

 Just to discuss the picture

They must be envisioning the 15,000 rpm type motor.
That small drive helical gear must not be a good choice for efficiency or longevity.


It does not show how the swingarm assembly is mounted at the pivot.

The regeneration and that tensioner slider thing would be questionable.

I see a place for drive line coushioning.

And how close could another entity come to this overall idea without violating this patent?

[Richard230]

That is interesting news. It is nice to see Can-Am make use of Alta's technology. That belt drive tensioning concept reminds me of what Buell was using before they got the H-D treatment. I hope they are successful as the electric motorcycle market could use some more competition to speed along the technology.

It's really interesting news... Can-Am have the clout to actually make a difference.

Update video from Can-am showing prototypes in testing, mostly of the Origin dual sport model including stop motion section showing ground up assembly.




In the comments to the video, Can-am reply to questions that specs and prices are coming in August, but it's also implied that the Pulse will arrive in August.

[Nairb]

another update video talking about the motor (episode 4) from a few days ago.  One clip shows 2170 style battery cells, noted by one of the commenters at 2:09 in.  Again in the replies to comments Can-Am say specs, pricing, and availability date coming in August...

[Richard230]

I wonder what kind of final drive system that bike has? It looks to me like it might be a fully enclosed belt drive like is used on some scooters.

[Grauteufel]

I think you're right about it being a belt, unfortunately no shots of it in the videos with its cover off but it doesn't sound chain-y. This also solves the complaints I've heard about zeros losing belts on gravel roads.

[princec]

Fully enclosed belt drive is such a no-brainer I wish Zero would get their act together on that...

From the linked July 24th Advpulse article:

"Looking closely at BRP’s patents, the battery is a load bearing structure in the chassis and is suspected to be made up of a total of 490 cells. Featuring a liquid-cooled power storage, the battery is expected to have a range of over 100 kilometers (~62 miles)"

They don't say where the info on the suspected number of cells comes from.  I suspect the liquid cooling is actually the motor and not the "power storage" as photos & the videos show a small radiator at the front of the battery, not unlike Energica bikes.  They do say level 2 charging, which is disappointing but not unexpected unfortunately.  Not much else in the article that wasn't covered in Can-Am's videos, but they do say they've already been invited to the US launch event in September.

[Specter]

The battery could very well be liquid cooled too.  Both pull in heat, and heat is going to be a much bigger problem with the battery than with the motor in the long run.

Heat exchanger (it's not actually a radiator) size is kind of a weird one because IIRC yes you need more surface area to dispose of more heat energy but also if your temperature difference is low you also need more surface area to keep transfer rates up. This is where heat pumps are great because they allow you to run a hotter heat exchanger.

If it can't do DC charging then you have to ask how much heat the battery is gonna build up during charging (the heaviest heat load) in the first place. I realise you can get up to 22kW from AC but the most common outlets tend to cap off at 7 and a 100km intended range is not going to be intended for long journeys (yes yes, small battery Energicas) and will likely be slow charged almost exclusively at home/office.

Overall, despite the short range there's some nice stuff on show. Stressed member battery boxes are a step in the right direction, I think the Ducati race bike is a view on things to come with everything bolted onto a power pack or single piece tub even if for road use the CF has to go.

[TheRan]

Using the battery as a structural member is all well and good for keeping weight down but I have two concerns. First off, in an accident it means it's more likely that not only does the frame get damaged but potentially also the battery, which makes up the majority of the cost of the bike. Even if the bike wasn't going to be repaired, someone with a more conventional bike with a damaged frame isn't likely to move everything over to a new frame, that now means the battery has to be scrapped instead of potentially going on the used market and into another bike. Secondly when the time comes for a battery replacement you're no longer undoing some bolts and dropping it out of the frame, you're completely tearing the bike apart to remove everything from the battery. More time consuming, more expensive, and it's going to require more specialised equipment.

[princec]

You could mitigate this with secondary protection. But let's face it, insurance premiums are going to be sky high, until batteries become commodity items.
