1) How far can I go?
The single most common question about EBikes is, how far can I go?
Somewhere between 36 and 73 kilometres on flat ground.
Many factors may even move this number lower or higher.
The formula to calculate battery power is as follows.
Multiply the Voltage by the Amp Hours and divide by the Wattage of hub and you get the time it will last
If running full throttle.
Therefore, a 36v500w hub with a 36v16ah battery would be. 36v x 16ah / 500w = 1.152 hours of full
Throttle operation. 32kph times 1.152 = 36.684k So at full throttle you would go over 36 kilometres,
If your maximum speed is 32 kilometres an hour (the legal ebike limit in Canada) you would go over
36 kilometres in distance.
However if you are on flat ground it only takes about 250 watts (about half throttle),
To maintain a speed of 32 kilometres 36 x 16 / 250 = 2.304 hours of half throttle operation.
2.30 hours at 32 kilometres per hour is 73.6 kilometres, So on perfectly flat ground with a light rider
And bike and no wind or stopping and starting you go over 73 kilometres and if you pedal.
2) What is included in an Ebike Conversion Kit?
1- Motorized Wheel (hub motor mounted in a rim)
2- Motor Controller (Either built in the wheel or included with kit)
3- Throttle with LED battery power indicator (Thumb or Twist)
4- Brake levers (to cut the motor and engage Regenerative Braking)
5- Control switch (Two button for Cruise, lights, etc)
6- All wires and plugs nessasary to install kit on your bike
What Else May I need?
1 - Freewheel and/or removal tool
2- Battery and possibly a rack to put it on.
3- USB cable to program the motor controller on a windows based PC
3) How to get sample and why don't you ship samples by sea.
You can buy samples form our dealers in your country or buy from us.
Wholesale discount will be returned back once you become our dealer.
Shipping charge by sea seems cheaper, but a very high port fee will be asked to pay when you pick up
Them on the sea port. Which total charge is much more expensive than Express.

|NO||Item||Golden Motor Magic Pie Series Motor||Other Brand Motors||Advantage and disadvantage|
|1||Integrated structural design||Integrated motor with built-in controller||motor with external controller||easy installation with bulit-in controller, save installation space and reduce wring fault for e-bike, the e-bike appears simple. easy maintainance|
|2||Reduction gear||brushless and gearless||gear||When 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.
|3||Multi-voltage||open voltage(24V-48V)||only one voltage: 24v or 36v or 48v||the 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.
|4||Multi-output power rate and speed||Magic pie iii& ii motor: 250W - 1000W Smart pie motor: 200W - 400W||250W||If 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.|
|5||Cooling and Radiating||Built-in cooling fan||no 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.
|6||Heavy current handling capability||30A||15A||As 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.|
|7||Programmable Intelligent Controller||Programmable||Non-programmable||Professional 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.|
|8||Regenerative braking||Available||unavailable||Magic 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.
|Available||unavailable||When 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.
|10||Plug-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.|
|11||Commonality||Commonality||Dedicated||The 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. (Notes: Chinese 250W, EU 250W, 750W, 500W, Canada, Australia, 200W)|
