Hi Uipko,
Thanks for the comparison data. Is the rowing bike higher (less aero) by any
chance? I wonder how a python would compare to these 2 bikes, given similar
dimensions and components. Steering a MBB does cost energy but python seems to
cost much less than MBB with positive trail and shorter BB-pivot, 10%?
Reducing load on the knees is another benefit of arm-assist. After a few
months, I would recommend the simple method of pushing on the thighs to any
rider who is comfortable going hands-free, since only limited power can be
applied, and only as needed to overcome some changes in wind or elevation
(variable assist). What to do with those free hands... :)
