BMS New (?) controllers ?

S12P 750W TORQUE SIMULATION SQUARE WAVE CONTROLLER
(web address says 250W!)

S12S 500W TORQUE SIMULATION SINE WAVE CONTROLLER

As usual for them- different wave shapes. It seems no pedal sensors, but an absolute lack of any real detail. What's this about?

From where did you get the idea that they have no PAS function?
All the compatible panels have multi-level PAS.

That is not what I said.

I said 'no pedal sensors' NOT no PAS.

But you never get pedal sensors with controllers unless you buy a kit. If you wanted one of those controllers and need a pedal sensor, you can buy one at the same time for $1.50. What you do need though if you want the display to show your speed, is the wheel speed sensor that costs $1.90.

Wish I'd known that when I bought the controller , now they want almost $50 in postage for a $2 part

Which bit are you missing, the PAS or the speed sensor? You can use a normal cycle computer sensor for the wheel-speed sensor. If you haven't got an old one, you can buy a complete cycle computer for about $3 and cut the sensor off. The PAS sensor is standard, so get one from Ebay.
