I would avoid a delta trike. They will flip easier in a turn. Both my trikes have been tadpoles, they track well in turns as long as you counter balance and don't lift a wheel. You also can't make them turn tighter than they want to. At speed all control inputs have to be gentle. These things are not like 2 wheel machines where you can shift weight to turn. You drive a trike more than ride it.

As far as Actionbent is concerned, it looks nice, there has been one in the LBS several times for minor adjustments. The owner has not been willing to offer a test ride even when I offered a chance to try my WC. oh well.

The sun tadpole, there are several occurances mentioned over on BROL.

I bought a EZ3 last summer just to feel what it was like to ride a recumbent. The price was OK, around $800.00 and the quality of the components used is pretty decent, it's easy enough to peddle and "your" visibility to others is better than a tadpole. I've never flipped it, but you can very easily, an avoidance move at 10mph will lift a wheel, as will taking a normal turn at an intersection at about 8mph. The track seems too narrow for the seat height, "you" are the CG on one of these. I think it would be a good bike for cruising around the neighborhood but I'd keep it off a bike trail unless it's flat and straight.

I've seen some pretty crazy stuff done on a HAAS, but they are too pricey for me.

Leaning trikes have complex systems which adds weight and cost and most require the rider's strength to keep them in an upright position.

I am designing a delta velo, with a 74" wheelbase, track of 34" and seat height of about 8", peddle only, no electric assist. I should be finished with the prototype by next summer. My current prototype is more of a small 3 wheel electric car than an actual bike. http://www.bricycles.com/

Interesting...I've heard more about tadpoles flipping than deltas, but the appropriate point here is that if either is pushed they will flip. I ride my EZ3 on the street, around the neighborhood and such and so I would say that for me it's a good place to start. I ride a recumbent and now a trike because of spine issues and I want to keep riding as long as I can. At this time this is the tool to do that. I just bought Big Apples to mount and hopefully that will add to the "suspension" and stability of the trike.

I'm glad that it's not the EZ3 that has the frame crack issues, although I have had a DF break on me, and wouldn't wish that on anyone.

It's almost here...Hope everyone has a great Holiday and New Year.

Tadpoles and "flipping": riding a vehicle that doesn't lean into turns just means you have to lean into the turns to counter the forces.
I've rolled once on my Micro going 35 mph during my first Seattle to Portland avoiding a large group of cyclists - once is all it takes (not doing that again!) chalk it up to inexperience at the time ( I had the Micro two months before my first STP).
Seven STP's later, my speeds are faster and have over 29000 miles ridden since I got the trike in May 2002.
I'm in the process of building a new trike from an ICE Qnt 26 frame kit, should be built up by February once all my parts arrive.
Learning the handling of the new trike will be a fun experience!

I bought a TriCruiser -- they start at $800 or so, a bargain IMO. I use mine for exercise... it is not a high-speed machine. But I LOVE it, especially with a NuVinci hub. And the support by the manufacturer is second to none. http://www.americruiser.com/

WOW! I think they have been selling longer than Raptor (another thread)! I purchased another trike available in So CA.: the S & B Venice Beach trike- and talk about flipping- terrific learning tadpole. Great to hear they are still operating!
