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.

EVBike battery voltage indicator – only voltage level
Question: When I press the button on the EVBike battery indicator, the battery shows to be 100% full or 80%, but when I drive just few hundred meters, the battery will be empty very soon. Where is the problem?
Answer: The EVBike battery indicator indicates the total voltage of the battery. With lithium cells, the battery has always the full voltage (with no load) even when the battery is nearly empty. It is important to understand that the indicator is only a voltage indicator – it is not a capacity indicator. For regular operation of the battery (with no load) this indicator should always be at 100% or 80%. If the indicator is bellow 80% (with no load) there may be some problem with the battery, or the battery is deeply discharged. 
In case your battery is empty, you should charge your battery as soon as possible. Never left empty batteries without charging!  Always charge the battery to full before storing your bike. 
If you stop using you EVBike with the empty battery, most likely you will find the battery damaged and not working properly several weeks or months later. This kind of damage is not covered by the warranty.
When driving your EVBike, the battery is under the load. You can try to press the EVBike battery voltage indicator while driving to see the voltage drop under load. If the voltage of the battery is low, the EVBike battery voltage indicator will show it. When the voltage of the battery is low, we suggest to charge as soon as possible.  The proper charging will extend the service life of the battery.
Please remember: First charge, then drive.
