TP (Tensile Python)
Built by me (User:Jonas Nordin) in 2024.
TP is a non-weld construction that utilises a few dyneema lines to take up various tensile loads. Hence the name Tensile Python. A fellow recumbent rider and friend of mine - Per Cronholm - initially suggested the name Tensegrity Python, but since it is technically not a true tensegrity construction, I chose to go with this similar name instead.
The line forming the lower part in the the rear triangle has multiple functions. In addition to taking up tensile loads it also acts as a spring -line-shock-absorber, takes some loads off from the pivot bearings and reinforces the self-centering effect from the steering geometry.
It is built mainly from a combination of a folding bicycle and a kick-bike in addition with a few extra leftover components from my garage. It also has some custom made 3D-prited components in PETG-plastic and some 5 mm aluminium-plates.
Dimensions BB-Seat Diff. and BB-EOS are variable measures. The measurements given here are therefore only representing the settings that I have chosen based on my self being the rider of this bicycle.
