A7 is not for chasing racing bikes, though I have managed to overtake a few. Its less than perfect aerodynamics and relatively high centre of gravity won't let you do what Quest and WAW, or even Strada and Mango will.
I think it's good for touring and commuting. It's not as
roomy as A4 or A6, but it's by far the roomier option than WAW or
go-one. Since it's higher than some other velomobiles, it's more
visible, it offers better visibility to a rider and it is less prone to
hitting bumps or litter on the road. But if often in the traffic, it's
better to get it equipped with turn signals.
It is comfy. Since
the seat can be moved forth and back with lots of angles possible, it's
hard not to find the set-up you need. Well, it's not as comfy as Orca,
in which I felt like in a car, but given ample room for adjustments
compared to other velos, A7 is very good in this respect. Yet if you
have issues with the lower back, Orca, A6 or Sunrider are easier to get
in and out.
It has good handling in most circumstances. Compared
to Orca, the A7's steering (A6, A7 and Quest alike) is more predictable.
I didn't like the overly sensitive joysticks on Orca. On the previous
version of Sunrider, the joysticks gave better control of the ride
definitely. Just to illustrate the well-implemented steering of A7, I
recall riding almost whole winter of 2011-12 on Duranos, I'm not
kidding! Well, I didn't ride everyday, the winter in Strasbourg wasn't
that snowy, but I rode mostly on bike lanes sometimes covered with ice
or snow. Plus, I had made the steering rods shorter thus making track
shorter and stability poorer. Either I was lucky, or as I stated above.
