Hubless e-Bike
Brand History
Describes the detailed specs and options of the hubless e-bike Top Secret.
Topsecret
Based on the design philosophy, the main tube was designed with a large curved shape to easily withstand force during driving, and the hubless wheel retains only its circular shape, intuitively demonstrating its function as a wheel.
Powerful Electric Drivetrain
Our self-developed mid-drive motor (750W48V) provides higher torque and performance compared to conventional hub motors, doubling its power, gaining more benefits from the gear system, and being easier to maintain. It is also placed at the center of gravity of the electric bike, helping to better distribute the bike's weight, making the electric bike more manageable. Power of over 140Nm from Mid- drive 750W motor
Large Capacity Battery Pack
Lithium-ion battery (48V20Ah) battery pack_(LG Energy Solution Cell) has high energy density and output. When using PAS (pedal assist system function), it can travel 130km on a single charge, enabling reasonable long-distance riding. The battery pack is designed to prevent overcharging, overcurrent, dust, and overheating, and is also designed to be removable for direct charging.
Safety Features - Airless tires
Airless tires were installed to solve the safety problems of existing bicycle tires. Airless tires have characteristics such as non-inflating, non-rupturing, bulletproof, explosion-proof, flame retardant, anti-slip, reduced heat generation, easy handling, and exchangeability. The gear that transmits wheel power has been developed with special heat treatment to prevent wear, and the large gears of the wheel body and driving part are manufactured to be separable and replaceable.
Hydraulic Brakes
It is difficult to install hydraulic brakes in the structure of a hubless electric bicycle, but we have solved this problem with our own technology and developed a more stable electric bicycle.
Headlamps and 1080P HD MINI CAMERA
An ambient light sensor detects darkness and automatically turns on and off the ultra-bright headlamps and tail lights. So you can stay safe no matter when you ride. The high-definition 1080P HD mini black box camera can record from 16GB to 128GB memory TF card (optional) for eight hours, and the view angle can be up to 120 degrees. PIR sensor, Standby 90Days, Built in 1,200mAh Lithium Battery. Auto Night Version. Consider the safety of the rider in case you don't know while driving the bicycle.
