Four huge problems the prevent the current iteration of the Spyder from being a capable off-road vehicle: 1. VSS: As noted, the Nanny that makes the Spyder docile on the road reacts poorly to things like gravel, dirt, sand, etc. You *can* ride over that stuff-- I have all the time-- but you're not going to go fast very easily or safely, and maneuverability is dependent on how much the Nanny wants to slip your traction. 2. Belt drive: The belt eats rocks for breakfast and spits out sprocket. Would need a completely sealed belt, or chain/shaft drive for the Spyder to be an off-road machine. 3. Remember the first-gen of three-wheel ATVs? Yeah.... three tracks is never fun on the dirt. You hit *everything*. 4. Suspension/height/weight: The Spyder's a low-riding trike. Making it capable of traversing rough terrain likely jeopardizes its road-handling capabilities, i.e. make it too tall or with too much suspension travel and the Nanny has to be redesigned. A "dual sport" Nanny/suspension setting, something you could adjust on the fly, would be a neat trick, but would also add $$$. Lastly, and perhaps terminally to our hopes: the Spyder is *big and heavy*. Asking for polite behavior down a dirt road is one thing; actually taking this thing offroad, you run the risk of flipping something that just isn't designed to flip-- *or* flip back.
