I bougth a touring SWB recumbent, an Optima Dingo, it weights about 18 Kg at the moment. It has thick semi-slicks on it (schwalbe supremes). I know it should be slower than Bacchetas and such, but I never imagined it will be so slow! I have already ridden around 500 Km with it since the summer, and my typical avg speed is around 20 km/h in mostly flat terrain in a calm day. With my road bike it's around 30 km/h in the same conditions. It seems like too big a difference! Do you think the problem is the bike design? (I notice my legs are much more tired after a recumbent ride than on my road bike) Or will it just take much more time until I'm finally reasonably fast with this bike?
