The frame construction and quality is very good on my Gekko Fx 20 but there are a few things that bother me about my trike. The front hydraulic disc brakes sometimes touch the spokes when I turn sharp. The folding on the HP Velotechnik video makes the folding look so easy and fast but I find it a bit difficult to fold underneath the frame. I thought for $2300.00 that the trike should have come with bar end shifters rather than the grip shifters.
