It occurs to me that the BMW e-scooter looks a lot like, and has similar performance to, the original Vectrix scooter - which I might add sold for $11,000 when it first came out, how many years ago? I am pretty sure that stuffing the latest LiFePo4 batteries into the Vectrix would get you the same performance as claimed by BMW.
I test rode a Vectrix some years ago and was impressed with its performance. I got it up to 65 mph on the Freeway and it had a real world range of 35 mph. My only complaint was that it was kind of large and would have taken up a lot of space in my garage - about two motorcycles worth. I also heard that they had cooling problems with the hub motor when running full throttle up hills for more than a couple of miles.
The original Vectrix had a 7kw cont / 20kw peak motor and a 3.7 kwh NiMH pack. A bit faster* and a bit more pack than the Enertia 3.1, though 200 lbs heavier (6.8s 0-50mph, 515 lbs).
* I'm actually surprised it's faster at all, with the extra weight.
Most recent Vectrix, Vectrix VX-1 Li and Li+ use a 3.7kwh and 5.4kwh lithium iron phosphate battery, 125V 30Ah and 43Ah respectively. Weight is down (425 and 460 lbs respectively), performance is up (6.0s 0-50mph and 6.2s 0-50mph respectively). Motor - peak 21 kw - and chassis are likely the same.
Prices are set at $12k and $14k USD respectively.
If the BMW comes in at $15k, then I'd expect to see a large price drop from Vectrix. The BMW is likely more powerful, may have more range than VX-1 Li+. Vectrix claims 55-85 mi or 88-136 km which is optimistic on the high end. We don't know how much battery the BMW scooter has, BMW claims 100 km.
Most importantly, BMW has the name and BMW has a dealer network.
