    Need Help With Stuck Higo Connectors

    Take a small, blunt flat bade screwdriver, like a small watchmakers one, and carefully insert it between the outer soft black plastic and the harder inner plastic of the connection.

    Magura MT5e Opener or Closer for Bafang M600?

    Best solder for shortening cables? (PAS, Motor etc)

    For signal wires 0.14mm² and 0.2mm² I would use 40/60 leaded electronics solder 0.7mm diameter. Even with these small signal wire diameters, I use a medium sized soldering tip that I clean with metal wool. Here some instructions on how to join a signal cable.

    I've been rebuilding 2 MACs for my AWD Fatty. Standard Stator and runner, standard gears (but greased with Aeroshell), and with a beefy clutch (up to 170Nm). It has a side entry motor cable and internal gear & temp sensor. Heavy duty use, so far no problem. Been tinkering with the idea of a...

    How to make EVERYTHING truly waterproof

    I wrote some articles on upgrading the Cycle Analyst V3 in order to waterproof it and even produced a kit to do that with. With your motor, fit a GORE pressure equalising valve to the hub housing, after you treated your stator with red PU spray to protect it from corrosion und you can forget...

    Grin Phase Runner / CA3 and BBSHD

    Hi all, I keep getting enquiries as to when I release a CA3-Phaserunner combo with HIGO connectors on the phaserunner and a plug&play set of cables for the BBSHD. The idea was to get some 'raw' phaserunners from Justin, wire it up with HIGOs and then encase it in epoxy. Justin so far is happy...

    BBSHD thottle response.

    The more I follow Bafang developements of their hardware, the more I don't like it. Apart from the fact that their support is non-existent, as is their spare parts supply, they keep springing surprises. Only really interested in you if you buy a large quantity of motors from them. I've thrown...

    Grin Phase Runner / CA3 and BBSHD

    The CA3-HIGO is more or less the standard CA3-DP/DPS upgrade. It is NOT suitable for use with BBSx controllers. With an adapter (HIGO to JST) you can use a CA3-HIGO with the Phaserunner. A full CA3/Phaserunner set (including plug and play harness) will be available later in the year.
