    Swytch Ebike Conversion Kit

    Why Swytch? afaik the common wisdom is that Swytch excel at marketing a pretty generic low powered system at a high premium cost. while the motors are pretty good the batteries are small and control systems limited in useful features. and the same money spent elsewhere will generally get you a...

    PAS sensor (KT-V12L) install issues

    My only reference for 12x magnet sensors having a bad rep is an incidental comment from one of the forum gurus in reply to my update of an initial pas issue with my conversion kit. The solution i ended up with was using a right hand sensor that required a steel plate on which the sensor is...

    PAS sensor (KT-V12L) install issues

    Any pas sensor will work in all probability and if your crank axle is just a tad wider than 17mm these can be a pita. afaik its generally the 12x magnet type sensors that give anyone a problem, so replacing a 12x magnet sensor shouldn't be an issue at all. If this design is too wide nothing...

    Handlebar display/controller unit

    a KT 15a sine wave controller and compatible lcd display (there is a range to select from ktlcd1.., ktlcd3 is popular/common), is a top shelf replacement option, partly due to the range of compatible displays and also because its fairly configurable with a detailed chenglish manual. (manuals...

    Battery and electronics to mate with Panasonic front hub motor.

    Trace the cable from the motor to its First connection, disconnect and photograph the motor end to validate its a standard 9x or 3x connection configuration. (probably 9x) . while the basic 4x pin battery connector initially looks promisingly simple, the "D" labelling on the 2 thinner wires...

    Topeak D2 Tyre Pressure Gauge

    The 'ebay' mod caps work a treat, my basic pump adaptor and fancy new battery pump are both geared towards schrader valves so after screwing up and buying a presta valved tube last time round its the way i went.. a bit more fiddley, as you need to open and close the presta valve in addition to...

    Ezee motor question

    Test the signal wire for a pulse with the wheel spun backward to confirm its a speed sensor, otherwise its possibly a temp sensor signal.

    Topeak D2 Tyre Pressure Gauge

    the valve needs to be open to enable a full pressure reading as said above.. if catered for what is different in the air passages between the 2 valve types, perhaps a packing fragment is obstructing or partially obstructing a crucial feed path?? and Shrader mod caps are available for Presta valves..

    If you cant the display from the bikes maker or its agents. any 3rd party option will be a punt as many bike makers will customise the controller system f/w used to communicate between the controller its display and often the battery bms. A drastic solution may apply if you can replace the...

    24v Battery Replacement Options

    @Peter.Bridge - seems ok, if the OP likes the lcd6 display? I Would urge consideration of brake cut off sensors too - again, last time il mention it.. - But.. Just consider approaching offset barriers like at the exit/entry to a bridleway, cracking a brake lever to disengage assistance allows...

    24v Battery Replacement Options

    Generic pas sensors tend to have 3 wire connections, and anything other than 2x hi-power connections to the battery is a red flag warning of superfluous battery communication features that in reality mainly just hamper the use of 3rd party batteries. So the above suggestions for a KT...
