About Battery

Battery capacity?

The capacity of the battery is 252 Wh with 36V and 7 Ah. Thanks to BZEN’s proprietary technology and electronics, the battery consumption is fully optimized and it allows an ideal range for city commuting. 

How to charge the battery?

To charge the battery, you must use the appropriate charger that is provided with the bike. You should simply connect the charger to any regular power plug  (220 / 230 V AC) and to the bike.

How often should I charge the battery?

The battery provides your bike with an average range of electric assist of 60 km. We recommend you to charge your battery when it reaches 50% charges. It will require only 1 hour to 1.5 hours to fully recharge your battery. And if you run out of battery, your simply pedal like you would be on a regular bike.

What is the battery lifespan?

The battery is designed for 500 cycles, equivalent to approximately 30.000 km. After the 500 cycles, the battery still has approximately 75% of its original capacity.

To secure the battery lifespan, it is important to maintain the bike and to recharge the battery every 6 to 8 weeks when not used.

How can I remove the battery from the frame?

BZEN has designed its frames and its battery for easy maintenance. All the electronic components inside the bike are connected with waterproof plugs. Any professional bike shop will easily remove the battery from the bottom of the frame, and in case it would be needed, he will replace it. You may also directly contact BZEN service by writing to

Does weather affect the battery?

Yes. Although the battery is fully protected inside the frame, temperature affects the battery. Certainly below zero degrees Celsius, the performance of the battery is reduced. And below 10 degrees Celsius, there is a high probability that the range of your battery is shorter.  

How can I optimize battery consumption?

As part of BZEN proprietary technology, all the bikes are equipped with a Battery Management System (BMS). The BMS will automatically optimize battery discharge and battery re-charge, avoid battery overheat and energy losses while securing the necessary power required by each component: motor, motor controller, lights.

The level of electric assist has an important impact on the battery range. Normal electric bike assist is equivalent to 1, 2 or 3 bars on the BZEN LCD controller. To provide a larger variety of assist, BZEN as a sport mode and a boost mode respectively with 4 or 5 bars set on the LCD screen. These 2 modes are consuming more electricity and shorten the battery range.
