Initial observations: http://visforvoltage.org/forum/9187-velomini-very-cool-little-folding-electric-bicycle-initial-review for pictures ..etc..
Just got through riding it to the day job. The ride is 2ish miles to the light rail station, a 5 minute wait for the train, a 10 minute ride on light rail, and a 2-5 minute ride from light rail to the office. This is fairly typical for one of the places where I think personal EV's would shine brightly - to extend the capability of existing mass transit. A small folding bicycle like the VeloMini is plausibly the best format for an personal EV to take advantage of existing mass transit.
About 2/3rds of the way to the train station my butt started to get sore. Fortunately the seat is standardized such that you can easily buy cushier replacements at the bicycle store. It does mean on the return trip home I'll be taking a different route with less seat-time.
This bicycle is definitely too small for me and the biggest flaw is that the seat nor handlebars can be adjusted to be very high. This might be fixable, especially as the seat tube is also a standardized part and surely there are longer seat tubes available.
It has good getupandgo and the ride to the train was pleasant and certainly not boring nor tedious. However there is a bus that goes along the same route I rode on the bicycle and IIRC the bus gets there faster than I did with the bike. On the other hand riding the bus means I'm subject to the bus schedule, the bus schedule doesn't always meet the train schedule appropriately, and riding the bicycle has the advantage of getting some exercise. Tradeoffs.
There isn't much on the bicycle of holes in the frame for securely locking the bike. There is one triangle in the rear that holds up the seat tube, so there is a hole where you could run a lock cable.
There isn't an obvious place to mount lights. Obviously with a bit of thought I could jury rig a way to mount lights. Also tapping into the electric system to power lights appears to be simple as all the connectors are in the open. However it would be really cool if this bike had appropriate lights built in - as in, the bike already has a battery pack so why not run the lights off that? It's summertime right now so lights are secondary as the daylight has enough hours that commutes will happen in the sunny period. But what about other parts of the year?
The electronics are neatly hidden in the frame tubes. Hence the whole bicycle is very stealth and you have to look hard to tell it's electric. It also means that repairing anything requires getting into the frame tubes to access the parts. There must be a way .. e.g. looks like a couple access hatches are screwed on. Will have to investigate tonight.
