E-Bike Systems: Front Hub System

Front Hub System

Thanks to the similar look of a front hub dynamo, which is typical for city and trekking bikes, the motor is quite hidden. Only the battery itself indicates that it is an electric power assisted cycle. 

Highlight features are the compact and powerful motor, the high capacity battery and a separate located small torque sensor. Especially the structure of a rear wheel, powered by the rider and the front wheel powered by a motor is similar to an all-wheel-drive of a car which is still a unique characteristic of the front hub motor systems. This double power system allows comfortable cycling.

Front Hub Motor

Thanks to the similar looks of a front hub dynamo, which is typical for city and trekking bikes, the motor is quite hidden. Only the battery itself indicates that it is an electric power assisted cycle. 
Highlight features are the compact and powerful motor, the high capacity battery and a separate located small torque sensor.

This double power system allows comfortable cycling. 

 

 

 


Torque Sensor

The high-precision torque sensor is responsive to changes in pedal power when starting, climbing or accelerating. A detector coil measures pedaling torque and sends an output power signal to the controller. This kind of technology allows measurement of the pedaling torque without contact of the axle, therefore without energy loss as well.

 

 

 

 

 

 


Front Hub Unit System - Rear Carrier Battery (36 V)
 

The rear carrier battery for the front hub motor unit was newly developed in year 2014. This rear carrier battery matches well to the city and comfort type of E-Bike. It allows shortening the total length of E-Bikes, like the triangle type of battery. Compared to even this triangle version it is still possible to use the deep entry to the bike, like it is typical for city and comfort bikes.

 

 


Console

The Center LCD console separates the display and operation buttons for easy visibility and usage. This console is designed to be visible even in strong sunlight, and tough enough to withstand rain, wind and dust. (IPX5)

36 V Charger - Front Hub Unit

This charger provides the same high quality in terms of efficiency and charging-safety as our high capacity battery technology. When the charging starts, a communication between the battery and the charger ensures a safe and optimized control of the electric current flow. For safety reasons there is no fan and no vent hole for protection from dust and moisture. 

- Charging on E-Bike is possible
- Indoor usage only
