Bottom bracket Torque sensor

Hi. first post on the forum!

Looking for a bottom bracket torqe sensor for my DIY e- bike. the only one i seam to be able to purchase is the Thun X- cell RT. But it only measures torque i one pedel and only torque as well.

I have seen some other bottom bracket torqe sensors on the market:

FAG torqe sensor:

My question is were can i get an hold of a bottom bracket torque sensor that measures torque i both pedals and also speed?

Best bet is to search for Torque Sensor here on ES, or to read thru the Cycle Analyst V3 Beta thread over in Ebike Reviews and Testing section, as there's been a fair bit of discussion about the available options and what is needed to make each work.

ebikes.ca sells the THUN brand BB torque sensor.
