Count me in as a lifelong DF rider with an equally long-standing curiosity about 'bents (I became curious with the early 'bents in the early 80's).

I have never ridden one, but have really become curious again in the last 5 years or so.

I like the idea of a trike or quad for the stability, but get a bit freaked out by the practicality and safety of riding such a low-slung vehicle in traffic or on MUP's. It is quite possible that these concerns are my own fabrications or projections, but I have repeatedly tried to visualize myself on a trike while riding my DF, and have wondered about visibility and footprint. For example, riding in the city, where parked cars are commonplace along most streets, I'd imagine a trike would be almost invisible (even with a flag) to cars entering the roadway from parking lots or side streets/alleys when compared to a DF with a front blinkie on the bars. I'd have to have a 3 foot extension on a trike to get a blinkie up that high, and my body wouldn't be visible. I've also wondered about the practicality of maneuvering a trike in heavy traffic, where a DF can offer alot of flexibility. Again the low position (I would imagine) would be pretty unnerving - sitting at wheel level of a bunch of vehicles who cannot see the rider, even worse so with SUV's.
So, that is my main concern with the trikes.

The two - wheeled 'bents sit a bit higher, and would seem to be more maneuverable than a trike. However, the 2-wheelers seem to pose their own issues - stability being the primary one - particularly at slow speeds, such as on busy MUP's or in heavy traffic. I shudder to think about losing my balance in traffic, though I realize the same could happen on a road bike.

So, concerns aside, I'm really intrigued with 'bents. I like the idea of being more upright, with no neck strain and more visibility.

Are there any here who have any urban exposure on their 2 and 3 (and 4) wheeled 'bents who can share experiences, things to consider, etc?
