Advantages of “TOP SECRET” e- Bike model
1. The strength of the innovative and future-oriented design with a spoke-less structure in the bicycle wheel.
2. An electric bicycle frame designed with high-strength ultra-light aircraft materials aluminum and titanium.
3. Equipped with airless (tubeless) tires that are safe from tire punctures when driving on unpaved roads or rough roads.
4. Noise and weight are reduced by using a specially manufactured ring for the rotating part of the wheel, and durability is increased by applying a special heat treatment method to the contact part of the ball.
5. The main body frame has a box-shaped structure and is finished with full-scale machining rather than a welded structure.
In addition, a construction method for corrosion prevention is applied.
6. It is a structure that is difficult to install on a hubless electric bicycle, but a hydraulic brake with very good braking power is applied through its own design technology.
7. The "TOP SECRET" hubless electric bicycle is designed to check all situations of the electric bicycle through steering of the handle and LCD display, and to be able to easily check all data and adjust according to the rider's body.
8. Gears, which are wheel power transmission, have undergone special heat treatment developed for wear resistance.
The large gears of the wheel body and driving part are designed to be separated and replaceable.
9. In the case of high-capacity battery packs, they can be directly charged or detachable, so they can be detached and recharged, and a safe lithium-ion battery that can prevent overcharge, overcurrent, over-dust protection, and overheating is applied. When using the PAS function on a single charge, it is possible to drive up to 130 km.
10. Pedaling is possible like a regular bicycle, and two additional functions
PAS function (a system in the form of an electric assist that drives a motor when the pedal is turned) and Throttle function (type that moves by driving a motor without turning a pedal)
11. A 750W48V motor with a torque of over 140N and a 48V20Ah battery pack (LG Energy Solution) applied.
