For a personal bike it makes sense, tho a purpose built bike makes more sense/more efficient/more economic if an e-bike is what you want at all.
But for a last-mile bike it seems like a brick of conspicuous consumption that takes your whole attache case.
One of the beautiful things about these bike systems is the relatively slow speed of the unit. It gets you across the short distance it is intended for much faster than walking but at a wheeled pace that is relaxing to most, good for heavy congestion for most & just seconds or a minute behind the typical I'm-a-car-too-look-at-me-go-fast-I-race-bikes mindset of too many (North American) cyclists, without lycra, without special shoes, without a +1000$ bike, even without a helmet. Much faster than a car when used to purpose, not because of speed, but because of space & parking considerations/costs.
Sweat? Not much at the bike system bike's optimal cadence while dressed appropriately for the temperature. You even get a breeze on a windless day while using the same energy as a pedestrian. Are they slow? No, they are purpose-built.
If you've ever been on a highway, exceeding the speed limit by 10 mph/kph the way we all do and laughed at that guy who needs to work so hard to go 10-5 mph/kph faster, changing lanes, revving, braking, changing gears, generally making an ass of themselves. Then you can't see them anymore, until you do, 30 minutes down the highway, 4 cars ahead of you in the drive-through. You know what I'm talking about. Bike system bike designs practically eliminate that mindset IMO, people getting on them intending to go fast...?
But this might be good for people without the physical stamina to pedal gently for a mile or who have some other impediment. I just find the speed/sweat arguments for it are misplaced concerns when talking about bike-share systems. Deliberate & effective use of a bike system makes those concerns go away altogether as it is now for most anyone.
Cool fun to design, but given the market & the unit cost it's a hard sell IMO. Except hipsters.
