Elechic

The advanced electric driving system used on Velorbis Elechic bicycles consists of six components:
1. Brushless motor with controller (double water protection, stainless steel axis, quality bearings and reliable magnet)
2. Display unit with iButton activation and removable multi-function computer (displays speed, trip, time and distance data)
3. Powerful Li-Ion battery pack (37V/9Ah Lithium-Ion with BMS)
4. Ergonomic support switch
5. Sensor with bracket
6. Cable set with connectors
*In-depth information regarding each of these components is included below.

It has been developed for front wheel assembly as two wheel traction (2x2) gives the best driving stability, optimal weight balance and allows for a free choice of rear wheel gear system.  The complete driving system weighs 10.37 kg. It features:
•    Motor support maximum 250 W
•   Full motor support up to 25 km/h. Support and range adjustable in 10 equal steps from low to high degree:
Motor support - Range
2 - Circa 85 km
4 - Circa 65 km
6 - Circa 50 km
8 - Circa 35 km
10 - Circa 25 km    
•    Charger: 42V/1, 8 A. Charging time: approximately 5 hours
•    System efficiency: 85%

Velorbis Elechic bicycles are not stock items and are built to order.  Lead times are 4-6 weeks.
*Please note that the Velorbis Student & Studine models are not included in the Velorbis Elechic range.

Further information:

1.    MOTOR
The advanced system used on all Velorbis Elechic bicycles is powered by a high quality brushless induction motor. This three phase hub motor has a higher torque at lower current that extends the bicycle range to many more kilometres. Its double water protection, stainless steel axis, quality bearing and reliable magnets are excellent long-life features. The controller and sensors are integrated in the motor. Efficient software to ensure outstanding performance and high reliability has been developed alongside the hardware. The unique Antec PAS-VARIO system for adjustable motor support from 10 to 90% can be enjoyed by all cyclists.

The controller is a single multi-layer round PCB with one-sided components. A new microprocessor makes the system very efficient and also highly reliable. Every single motor is tested after inserting the controller and downloading the PAS-VARIO software. The ready to use motor does not require any further use of PC’s.

2.    DISPLAY
The display in the middle of the handlebar provides all the important data at a glance. It has two led bars showing battery condition and motor support as well as a removable multi-function computer indicating speed, trip, time and total distance. The system can only be activated by a unique iButton safety device. This means that each bicycle has an electronic and a mechanical lock. Furthermore, an automatic shut-off prevents the unwanted discharge of the battery pack. 

3.    BATTERY PACK
A new light and powerful Lithium Ion battery pack is featured on all Elechic bicycles, with a Battery Management System (BMS) providing the energy. The battery pack can be delivered in a customised bicycle bag or in a small watertight battery bag with customised luggage carrier. This way it is smartly hidden under the saddle and is easily removable from the bicycle. Lithium Ion battery packs have the best cycle life and performance levels, while being safe and environmentally friendly. The pack is rechargeable in around 5 hours with the small charger.

4.    SUPPORT SWITCH
The degree of support can be adjusted by the switch placed near the left grip. There is no need to take your hands of the grips. The degree of support is clearly visible on the display. The switch is also used to activate and de-activate the electronic system.

5.    SENSOR
A special sensor is placed on a stainless steel bracket near the chain wheel. The sensor registers both speed and direction. The electronic system uses these signals to calculate the pedalling force and adjusts the motor support accordingly. This is the best way to avoid torque- or optical-sensors with difficult calibration procedures. 

6.    CABLE SET WITH CONNECTORS
To complete the advanced electric driving system, cable assembly for quality connections is included. This is important as it ensures many years of reliable usage. The choice of first class water protected cables and connectors are the best guarantee for durability. Cable sets go through a rigorous quality control process as do all the other components.
