Been researching lately and found a couple of interest, one as stated, I'll probably get this year. DECO line of products seem to tick all the boxes for me. I'm not affiliated in any way. Have scooters & motorcycles, which I didn't realize there is a difference by definition, as I called everything with 2 wheels as scooter, whether a Honda Scoopy or big ol' Hog.
Anyway, DECO has some nice 1 & 2000w products & one 3000w engine scooter. Latter with higher speed & range, and price tag of course. If your drive your scooter hard, like myself, may be the one that can take a beating. Although you will look like a Panda food delivery guy if leaving the rear storage box on

The Suzuki / SUSU model, not that I need the extra power or distance, but better to have. If not that, maybe the Super Ace.
All in the same 'class' (1k or 2kw) seem to be similar specs, just styled differently. A few 1000w & 2000w models to choose. Don't think I would consider anything less than 2000w.
DECO gives the impression of no registration & tagging, a major plus, unless rural and staying that way. If so, then should also peek at this brand / model, which I'm having a hard time linking, without the BS, so if interested, just Google the name. Actually have one for sale locally on FB Marketplace for 40k:

See the tag mount, but yet to seen one with tags.
