Question: I have the EVBike Wheel Kit 36V/500W with 36V/10Ah battery. I try to get the maximal speed. I have set the speed of the controller to 40 km/h, but my speed is lower than this. What is the problem?
Answer: There is no problem. This situation is OK and fully normal.  The maximal speed depends on the battery voltage and the number of the power assist which you set on LCD (from 0-5). Your system works correctly.
The speed value that can be set in the LCD menu is the limit when the main controller unit will cut off power: if you set 20 km/h, the power will be cut off when you reach the 20 km/h. If you set 40 km/h, the system will work till this speed.
For technical reason the maximal speed is dependent on voltage of your battery. If you are using the 36V battery the maximum speed will be about 27 km/h at a flat terrain. If you use the 48V battery the speed will increase about +5 km/h.  For 40 km/h you need to use higher battery voltage and a more power and different controller unit (regulator). At this moment GWL does not sell such high speed components.
The maximal speed is depending also on the size of the rims. The bike with 28” wheel rims has a higher speed than a bike with 26” rims or perhaps just 20” rims.
We recommend to find more information on some web forum internationally or at your country – there are many e-bikers who discuss similar questions as you.

FAQ: With the news regulation in Germany, it is possible to have the headlight powered from the EVBike Battery. Do you have any solution? 

Answer: We keep suggesting that the headlight (white) and back light (red) should be battery-independent with their own power. This is also for your safety if your battery becomes fully discharged during your trip at night. We do not offer the sales of these products because these lights can be easily purchased from local bike-shops. 

The EVBike batteries do not support the 5V or 12V output for the headlights now.  Even though the controller and display unit may have the support function available, the physical wiring is missing. The „light sign“ is available only as the backlight for the display. 

If you wish to have a 12V output for your headlights or 5V for LED lights or for charging your 5V mobile device, we suggest you make your own solution. You may use some suitable type DC/DC converters for 5/12V output. On eBay or Hobby-King you can find many cheap items, like this one LM2596HVS DC-DC. The DC/DC inverter is powered directly from the 36V of the EVBike battery.

Freewheels for EVBike - available from specialized companies

FAQ: I just bought 36v500w 26“ rear EVBike set. I tried to install Shimano freewheel on it, but it has a lock. In my bike repair shop, they told me that I need spacer for the freewheel. What dimension should be for 7 speed Shimano freewheel?

Answer: There are different combinations of the free-wheels,  we suggest to consult the professional bike components companies who have a wide range of accessories including the spacers.  Some companies offer freewheels designed for E-Bikes (EVBike) directly. See example of such promotion leaflet from a supplier called Sunrace.

The new profesional Battery for EV bikes 36V & 48V

The new series of batteries for electric bikes, contains smart BMS circuit that continuously monitors the quality of internal cells and in case of failure, provides actual information through an LED panel. Please see PDF specification of LED faults. This circuit also protects the battery against deep discharge. 

NOTE:

If the battery is discharged so that it turns off the internal BMS module, next charging turns up in a few hours. Therefore is necessary to keep connected charger on the battery until it does not start charging.

Proper cable connection for the EVBike battery wiring is a must
We suggest all EVBike users keep checking connection the wiring of the EVBike battery holder. 
Improper connection will result in poor performance and over-heating.
