I disagree. I have a 15 Ahr 48V battery that weighs 18 lbs. Assuming half the weight of the device is batteries, allowing for an 80% DOD (and you will NOT get 1000s of cycles out of a battery taking it to 80% DOD every time), assuming roughly the same energy density as the above battery, and 18 Wh/mi, this leads to a maximum range of less than 10 miles.
The only range spec that makes sense is motor only. If you including pedaling, the range is infinity.
That said, there is an aesthetic appeal to this device. I think there are people who could use this and be very happy with it. However, it is an even smaller slice of the market than ebikes have already. I'd like to see them succeed, but based on the past performance of the ebike market, I think they will sell all they can pretty quickly and then they will go under when they start supporting them in use. But I am perennially bad at predicting what will be a financial success.
