NCD operation system It is the world's first NCD bike generator that works using the magnetic field. |
![]() |
The principle of Arago's disc The idea is that, when the bicycle starts running, a dense magnetic field filled between the wheel rim and the generator will rotate the generator's head without causing frictions, and generate electricity as a result. |
![]() |
Electricity generation You can create electric power while riding. You don't need extra batteries. Charge the lights with the power you create yourself by cycling. |
![]() |
USB charging type All devices that use USB can be easily charged by the generator. There is no charging terminal in the direct charge models, so it is tightly sealed when sent out to prevent dust or impurities from getting in. |

||
1. Depending on the thickness of the sheet and fork, select the right rubber pads and crescents and brackets. assemble all of them together. | 2. Using the installation guide, identify the right position to install. | 3. Place the bracket into the position and secure it with bolts and nuts. (fasten it slightly loose for more position adjustment) |

4. Insert the main unit into the fixed bracket and fasten it with nuts and bolts. after final position check, fasten the bracket tightly. | 5. Installation complete (contact type) | 6. Installation complete (non contact type) |
Universal Bracket Bracket that could reduce vibration by applying 2 different steps. Whether it'd be the front or rear wheels, it can be still installed easily. |

Hybrid type By changing the rubber ring regularly, the operation type can be switched easily. When you are doing a slower riding, but if you need much faster recharging! Use it as a contact-type in that case. To keep the tires from wearing out, the booster ring W needs to be contacted with the rim Tightly. |

Easy pedaling Unlike conventional bike generators, the resistance against the pedal is low. So the pedaling is much lighter, easier and smoother. Resistance per driving energy (driving test results at 25km/h) 2 % non contact 5 % contact |
Reliability testing For safety assurance, we have conducted rigorous tests. - Drop and shock resistance tests - Thermal resistance tests - Low-temp resistance tests - Water-proof/ dust-proof testing - Vibration tests - Pedal resistance test |
Water-proof IPX5 water proof grade. It can be used in the rain, but make sure that the USB terminal should not be wet by water. |
