The ND series from Fardriver (Nanjing Yuanqu Technology) is a family of hall-sensor vector controllers for hub-motor and mid-motor vehicles above typical e-bike power levels. Both models listed here share the same 189 × 121 × 63.5 mm potted housing and a 48–72V operating range.
Current limits, forward/reverse speeds, economy speed and throttle response are all adjustable through the configuration software, and the controller supports energy feedback (regen). Fault codes cover hall and throttle faults, over-current, voltage out of range, motor and controller over-temperature and phase short circuit.
Power levels are well above EU pedelec limits; these are for off-road, L-category or export builds.

FAQ
Is it suitable for EU pedelecs?
No. These controllers are for high-power vehicles well above 250W.
Which motors does it support?
Hall-sensor permanent-magnet motors; parameters must be matched to the motor.
