    Default Best innovative thinking behind a e-assist design I've seen thus far.

    Sounds great in theory, curious to see how this actually works in practice.

    sounds like a perpetual motion machine, which is totally practical

    The utmost in the "stealthiest" bike category would be type that have not only the batteries hidden in a slender frame, but eschew the hub motor in favor of a miniature, high performance motor built into the seat's down tube. In either case, it is an engineering challenge to pack a powerful motor, and the amperage to drive it, into a small package... and a premium is being paid for the "stealth" part.
    IF a cyclist is determined to use the boost only in the "startup" and "hill climb" exclusively, AND the regenerative braking charging circuit is very efficient, it may be able to carry on without an external charge.
    The weight is a problem; with it pushing 30 pounds, you may have better results riding an exquisite, lively, lightweight $3,000 non e-bike than this $4000+ bike.
    For my money, I'd rather leave my ego at the door and get an e-bike at a fraction of the cost, and not try to fool anyone. The cost of the power to charge an e-bike battery is negligible.
    I like the innovation though, equipping a bike with a quality, light frame with lightweight, efficient e-bike componentry could provide the best of both worlds.
    That hub and the beefier spokes aren't going to fool the critical eye though, if that's the game here.....

    I love it. The ridiculous $5000 super-niche bikes of today inspire the more reasonable bikes of tomorrow. And really, unless you live in a flat world, riding a fixie is finding the middle ground between "my knees are going to explode" downhill and "I literally can not advance this bicycle any further" uphill. Having a bit of boost means you can ride a taller gear without dying on the uphills.

    If advances in ebikes get more people riding fixed, it's a net gain for humanity

    Hmm. I have no problem pushing around a 45 pound commuter "analogue" bike on a daily basis. Sure, I am slower on my commuter than on my sub 20-pound gravel race bike, but the point of a commuter bike (IMO) is to be a work horse, not a race horse.

    Rule #5. HTFU. Ride the heavy bike. It only makes you faster on the lighter bike.

    I agree with that... I've always been a thrifty cyclist myself... but I'm positing that at over $4,000, this e-bike with a diminutive 250-watt motor is placing itself at a price point higher than a most exotic non-ebike. As for the "fixie" aspect, I'd agree that having e-bike power removes much of the need for gearing... a 3-speed would be ideal.

    My annoyance with it lies more in the pseudo-advertising-copy. I really have my doubts that it's actually a fixed gear, although I was unable to confirm or reject this suspicion looking at the article (only hint is that the article isn't included in the "Fixies" category). I get that language changes, but using "fixie" or "fixed gear" to describe the aesthetics of something when it's functionally very different still annoys me. One of the other bikes linked to in this article is described as a "stunningly minimalistic e-fixie" that has "fixie style" handlebars, but "the charge is obtained through an energy recovery sytsem, when going downhill or freewheeling".

    Yes. In the second paragraph of the article is this line:
    "The Nua Electrica is the stealthiest single-speed e-bike we've seen to date ..."

    Many people confuse "single speed" with "fixed gear" or "fixie".
