I don't ebike, but for my regular bike, I have one of these: https://www.amazon.com/gp/product/B000AOA3W6/. It's extra long, and it's the widest lock, the same as the fuggedahboutit.
Idk if pinheads can be used for ebikes, but if they can, you should get those too.
I use this (https://www.amazon.com/gp/product/B000AOA3W6/) for rear tire + frame (locked to rack/post/etc), and this (https://www.amazon.com/Kryptonite-New-York-Standard-Lock/dp/B06XCH21YH/) for locking my front tire to the frame.
