ED/T4 Controller FWD

Torque sensing controllor from eZee T4 series e-bikes. Diagnosis of problems on this system is very challenging, to the extent that we recommend against simply ordering this product and hoping for the best. 

To order this product and have the best chance of it working, please:

• send us a picture your motor plug connector
• send us the numbers for firmware that were used. This involves getting information from the display according to this video. It's only possible when the controllor and display are both powering up, which isnt' always possible when you're troubleshooting a problematic e-bike.
