Really stable,Ive had it up to 32 mph,that was to fast,**** happens quick,I stay around 20.
Eh...? 20 mph on that bike with that board overhead? Not happening unless it's all downhill from your crib to the beach. You're likely doing 10-12 mph on the flats, maybe.
How many people does it take to unstrap that setup? Because it looks like you unstrap one end of the longboard & then have to move to the other, lending added chances to the situation for board falling off.
