Re: Cycling for Disabled People.
'Best' is what works for you, hence the suggestions to go and try some (or state your location: someone might be willing to let you try theirs). IME a mesh seat is easier to adjust than a hardshell to reduce pressure on painful spots / match you lumbar curve. I find a suspended 20" wheel (ICE '...

Re: Suspension power losses/savings
Our bodies bounce badly by comparison and that is the source of Heine’s suspension losses. But how does he measure these internal losses? IIRC he inferred them by coasting downhill over rumble strips and observing the speed change vs riding on the smoother surface alongside. US-style rumble strips ...

Re: Suspension power losses/savings
Given that the losses are in the tyres, it has to be a pretty special suspension that reduces tyre losses on relatively high frequency surface roughness eg with cyclic repetition within the tyre footprint length Which losses are you referring to here? The major energy losses in riding a bicycle on ...
