The Motor 01 is the 3 kW electric hub motor by CAKE, used in the Makka.
¶ Versions
This motor appears to be used across all Makka variants. Although the Makka range is rated at 1 kW peak power, it seems to use the same motor and controller as the Makka Flex :work, which is rated at 3.3 kW peak power.
This strongly suggests that the lower power output on standard Makka models is enforced via controller software rather than hardware differences.
¶ Specifications
The hub motor used in the CAKE Makka is a modified version of the QS205 spoke hub motor manufactured by QS Motor. The exact product page for this motor is preserved here:
