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.
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.

The Yellow Connector - Often repeated mistake of the EVBike installation
Recently we have had several customers making a similar mistake during the installation of the EVBike kit. It is related to proper connecting of the yellow connector.
Both the accelerator (had grip) and PAS (pedelec assisting sensor) have the same yellow connector. During the installation, please make sure, that the accelerator connector goes to the yellow connector on a handlebar (to the central cable) and PAS goes to yellow connector coming directly from the controller.
FAQ: EVBike Kits - which to choose? How to install the rear one?
Question: I want to get the EVBike conversion kit. Which type of the kit do you suggest: the front or the rear wheel?
Answer: we sell both types of kits. We do not prefer any type of the kit. The customer must decide which EVBike kit to choose.
See some guide lines for the rear wheel drive kit: Even though rear wheel drive conversion may seem more complex and not that easy to install as a front wheel drive, it has these advantages:
- The rear fork is stronger (this is a must for high power projects)
- The disc brake fits more probably
- The “motorbike” design and feel
See above the picture with a nine speed freewheel. (The motor is the same dimensions as the EVBike 500W motor). You may need to use a washer to make a bigger distance between freewheel and motor (in case the chain interferes with the motor). Another washer might be needed for the other side of the free-wheel (in case the chain interferes with rear fork). These washers may widen the standard dropout of 135mm a bit. However it is not a problem in most cases.
Question: Do you sell the 7 gears free-wheel cassette?
Answer: We do not sell the free-wheel spare parts any more. Customers prefer various brand types and sizes of the free-wheels: 6, 7, 8, 9. It is easier you can buy such a free-wheel according to your wish in your local bicycle shops.
Note: please note that you must use a freewheel with the thread, not the cassette type! (see details here)
EVBIke Dual - make your life easy!
The tandem (dual) bikes are very good examples where the EVBike traction systems give the additional power to move ahead.
