The "trikes vs. quads" thread and others have been making me wonder why more hasn't been done to develop stability systems that could allow single track recumbents to have the kind of low speed and stationary stability of trikes and quads. In the powered vehicle world there is a motorcycle called an Ecomobile and its successor the Monotrace. Essentially they are motorcycles but are equipped with outrigger wheels that are manually deployed but are also tied in to the traction control system and will deploy automatically if they sense that vehicle speed is too low to maintain balance. A good thing because the rider is unable to put his feet on the ground to support the vehicle. It seems to me that design along these lines in the HPV arena could allow for the relative simplicity of the single track system along with freedom from having to use ones feet to keep the vehicle upright at stops. This allows for fully enclosed bodywork and greater confidence overall. Any thoughts anyone?

Several streamliners I've seen have some sort of landing gear. Part of the trick is designing something that can retract and leave a smooth body panel - in the HPV world, openings cause drag.

Yeah I've run with that idea a few times
but
weight {i don't have the means to do ultra light]
and it ending up looking like a mess of wheels :)
Fun idea

I've used landing gear in a couple of different streamliners. Because its usually a rollerblade sized wheel you don't really want to ride on it. Placement also tends to make them unusable for anything over about 1mph, otherwise you tip over. With a larger wheel you might be ok but honestly I think handling skill/ steering geometry can get you down to walking speed on a 'bent.

Easy, put some inline skate wheels to a double legged kickstand (preferably springloaded).
