Seat angle adjustment

[[email protected]]

Hi bent friends,

If I recline the seat more on the bike do I need to slide it forward or
backward to compensate for the change in distance to pedals? Thank you
for your help as always. Anj

It will depend upon the specific implementation: on my Streetmachine
there's no need, but I can think of possible mechanisms where it might
need doing. The easy way to find out is empirically: alter the angle,
and see if you have a problem pedalling...

It depends on the seat, if I reclined my mesh seat on the Vision it did not
affect distance to the pedals, if I recline my hardshell it requires
shortening of the boom to compensate

The constant point is 9 inches up from the seat bottom. You measure that
distance from the crank spindle to the constant point. All seats on
every recumbent your ride can now be set. Every one has the same
characteristic distance and can adjust all seats to the same distance.

I have noticed that reclining the seat on Rocket requires I move the
seat forward. I suspect that on the Rans with it's fixed seat, the
lowering of the back raised the front edge to the seat and my legs
effectively shortening them. At least that is my theory.

Not a theory, that's accurate and the same thing happens with my Baron
hardshell
