    Cycle Analyst V3, shorted to motor phase wires, now dead

    Rear spring rate for Greyborgs latest frame

    Just came back after an aweful ride on my newly built greyborg frame. I bought a new spring for my Fox shock, took the stiffest I could find at 550lbs/inch.

    Battery configuration, bad idea? 11S using 2S

    I have built 2 ebikes using 16S LiFe batterys (58,4V fully charged) for commuting and general riding to and from the store and so on.

    Hi! Long time reader, first time writer (from Sweden so please be easy on my spelling and language :oops: ). For a long story short, read the last bold lines that sums it up pretty well.
