BlindXX, I'm in Sarf London, I own a KMX - K and you are very welcome to give it a spin sometime.
In essence the K class is a three wheel mountain bike. It is heavy and not geared for the road either.
All the newer classes of KMX have the same basic 'frame' so are just as heavy and prone to the same failings.(Mickle or Spandex are best to talk to, the welds holding the rear section fastenings are prone to snap?)
The KMX improved when I stuck narrow slick tyres on it and when I have the spare cash I intend to get road dedicated rings and cassette and get the frame welded so it is rigid, but it will only be for fun.
I bought mine second hand after I sustained a knee injury and a recumbent was the most recommended way for me to be able to still ride and build up my muscles safely, which it did.
I too would love to have the cash to buy a better trike or recumbent cycle but as a class of cycle the trike is one of the more expensive when starting out.
