Not much has been revealed about the FACTOR-e motor. The following illustration comes from the 2025 parts book.
We do know that it operates at a higher RPM than its predecessors. It also appears to be much more compact than its predecessors.
We can also see that it has a removable inertia disc (flywheel). Item number 11 is standard for the FACTOR-e. From the drawing, it appears to have more material near the perimeter and weight-reduction cutouts near the center when compared with item number 11' (which is for the Race/Escape R models). Electric Motion provides the following information:
11 TC03R-50601-00-00 INERTIA, STANDARD, 1430 grams
11' TC03T-50601-00-00 INERTIA, OPTION, 940 grams (Standard for ESCAPE R and RACE)
11'' TC99U-50601-00-00 INERTIA, OPTION, 1210 grams
The motor itself is part number TC03R-40100-03-00. Its price is available on request.
The motor encoder (not shown) is part number TC03R-50415-00-00-ASM. Priced at $253.00, it is considerably less expensive than the encoder used on the Epure bikes.
Three special tools are shown with the motor parts. Prices are said to be available on request.
