Like a compleat plank i left my bike in "Park" instead of "Lock" so the lights were on and now i have a flat battery, i have tryed to bump it and after much huffing and puffing and running up and down the slight hill outside my house i have given up. can i jump start it from my car? or will that make the weels fall off or some other sort of expensive damage, if this is a no go how can i get it going with out having to shell out for a battery charger.
