Although the bike doesn't wiegh 300 lbs, it would take a couple of hefty guys to lift it that high. Thanks for your concern, but I took the picture after I'd removed the lock on the rear wheel and frame. That's quite enough security for dropping in at the liquor store in a 'tony' part of Toronto.
As far as the front wheels go, It's a brushless hub so I have to pedal to get it going. I have spun the wheels in snow and on ice, and it tends to slide to the right. On dry pavement, the traction has been great. Strangely it is the rear wheels that seem to spin most often. I've just changed the front crank for a much larger one so when I'm pedalling with some assistance I can go about 25-30 kmp/hr. I have a 42 km commute each day, so I really need to keep a fairly high top speed. It's taking me about an hour each way currently, that's averaging about 20 km/hr. Pretty good considering getting there is mostly up hill. Check
