There are plenty of folding bikes, and plenty of electric bikes. But not too many bikes that are both 
electric and folding. The Santa Clara California company ELV Motors released their latest bike the VeloMini fold-and-carry electric bike.
You can pedal the bike the old fashioned way, or do nothing and use full electric mode, or a combo of assisted electric pedaling.
The bike is perfect for bus or train commuters to bridge the last few miles. The only problem I see is the $1,050 price tag. For that hefty price you get the bike (ready to use after a charge), a carry bag, and a toolkit. The bike weighs in at 32 pounds
