4. Golden Motor Magic Pie Series Motor Advantage
--- High performance, High reliability, High efficiency


NOItemGolden Motor                Magic Pie Series Motor Other Brand MotorsAdvantage and disadvantage
1Integrated structural designIntegrated motor with built-in controller  motor with external controllereasy installation with bulit-in controller, save installation space and reduce wring fault for e-bike, the e-bike appears simple. easy maintainance 
2Reduction gearbrushless and gearlessgearWhen e-bike overloads or climbs, the gear is easy heating with deformation. Then gear ware will result in the teeth fracture and motor can not work.
Gear structure will bring noise, low efficiency and short range.
3Multi-voltageopen voltage(24V-48V)only one voltage: 24v or 36v or 48vthe voltage of the battery is proportional to the revolution of the motor.
As the the magic pie series motor is geearless, it has no wear and tear. Besides, when designing, the multi-voltage are taken into consideration and the motor can work effectively under different voltage. So the user can improve the speed and power rate by replacing the battery to adapt to the different riding terrain and load.
4Multi-output power rate and speedMagic pie iii& ii motor: 250W - 1000W                                                Smart pie motor:                         200W - 400W 250WIf you want to upgrade the power and speed of the e-bike, just replace the battery. i t is unnecessary for you to  replace the motor and controller.
5Cooling and RadiatingBuilt-in cooling fanno cooling fan According to scientific testing and user experience, good thermal has a great impact on the the reliability and efficiency of  the motor and controller.
Built - in cooling fan can quickly diserse the 60% heat generated by the motor, greatly improving the performance and reliability of the motor and controller. The advantage appears apparently when climbing the long slop.
6Heavy current handling capability30A15AAs the  controller uses high - quality, high - capacity power components, it can handle the  momently heavy-current output, enhancing  the accelerated performance and climbing ability of electric vehicles and greatly reducing the burned possibilty of motor and controller under the impact of heavy current.
7Programmable Intelligent ControllerProgrammableNon-programmableProfessional users or dealers can programm the controller via  USB to PC so that you can adjust and optimize the electronic control parameters. Then the e-bike will be safer and more comfortable when riding. Riders can enjoy the longer range and  the life span.
8Regenerative brakingAvailableunavailableMagic pie series motor has the unique and reliable regenerative braking function.
When breaking, the motor becomes the generator. it can break quickly and smoothly and let the inertial kinetic energy to become  electricity charging the battery. With this unique function, rider will enjoy the safe and comfortabel journey and  longer range. When downhill, it also re-charge the battery and decelerate.
9Overheat and
Overload
Protection
AvailableunavailableWhen the e-bike overloads and climbs  the long slope under high temperature, motor and controller is easy to over-heating.
Controller of magic pie motor has the bulilt -in sensor which can detect the internal temperature. If it beyonds the
  the allowable temperature, the controller will timely stop the power supply to the motor and  shut down the system avoiding the damage. User will re-start the e-bike after the ebike cools naturally. The controller will detect the temperature again. If the temperature is lower than the the set protection value, the motor will work again. This function will reduce product failure rates and protect the customer ' s property.
10Plug-and-play integration harness, wires exit from mid of shaft 

Waterproof, anti- wrong, plug-and-play military standard connector harness. Convenience, aesthetics, and reliable. User-replaceable, and greatly reduce the after-sales service.   Other brand motors use cheaper loose connetors, wires exit from hollow shaft end which can cut wires/cables easily during transportation, or when the ebikes fall down to ground at the side.
11Commonality CommonalityDedicatedThe ultra-thin wheel hub design suits for most standard bicycle (front wheel (100mm) / rear wheel (135mm) )installation. DIY modifications is available. it supports disc breaks and transmissions. Power rate and the speed of the motor can be programmable to abserve the local regulation. it is universal.
