There were two on the Bay, one for 1350 and an all singing & dancing Dt swiss/Rolhof version for near 2K.
Used prices are high as a niche market for them, I think the two on the Bay are at least 10 yrs old.
Having been passed and left in the dust by 2 wheel recumbents I decided they weren't for me so I bought a trike...
Gaz, you are lying down (so comfortable) and downhill or on the flat you don't need a motor. There is a steepish learning curve and you will be looked upon as eccentric by younger men as you thrash them despite not wearing lycra. Any more questions?
