Gearless hub engines are seldom used for heavy cargo vechicles, hubs are best for speed, road, cargo needs higher torque, the temperature rise of motor might be a problem.
For a cargo trike with total weight of 500kg (vehicle, driver, battery & cargo), max. speed 40km/h, wheel radius with tyre 0.2344m (120/70-12), bellow is calculation, considering that the EV cross section area is 1.5, with windage resistance factor 0.5. On the ground, the EV needs 452.89RPM while the torque is 28.02N.m (14.0N.m for each motor, driven by 2 motors). @40kmh on flat the motor out power is 1329.03W (664W each). When climbing a 9 degree slope (15.64%) @10KPH /113.22RPM, the EV needs max. torque 195.44N.m (97.7N.m each). The 27H V1 motor might work, the 1500W 260 30H V1 motor is better, considering the temperature rise and high torque on the slope.
