This is my first post on this site and so I will say first of all that what I say is only my opinion. That is unless my girlfriend is looking over my shoulder and telling me to type things in which case her opinions are my opinions...yes darling I wrote that ;O)
I have an ICE QNT trike. I bought it this year and it is my first recumbent, I am 52 and pretty fit. I also have a very nice TREK streetbike. The difference is like chalk and cheese.
The TREK is faster along the flat and uphill but the ICE is faster downhill. When you reach a hill with the trike the only thing you can do is find a low gear and keep spinning.
You can put loads of luggage on the trike and not even realise it is there, unlike a 2 wheeler.
I can sit and drink coffee, eat my lunch while I am riding the trike. I can stop and rest anytime I want without getting off and that is a big advantage. I have stopped and fallen asleep in the sun while sitting on the trike.
I can ride 60 miles a day on the trike and get off as though I have not done anything and I can do that day after day. There is no leg ache, back ache etc, associated with a regular 2 wheeler.
.
My view of a trike is that it is built for comfort and not speed. You can relax and take in the surroundings and just chill out. A recumbent bike is to get somewhere a lot quicker.
Here is a clip of me on my ICE...if it works.
