Something About the E·Pas You May Want to Know
How Does the E·pas Work?

Made You Ride Faster, over 24 mph at Pedals Assistance Mode 0/1 for longer that thanks to the energy regeneration tech that charges the battery automatically for 20% power from your ride.
Meanwhile, the intelligent sensor engages the E.pas system to regenerate 60% energy when you’re going downhill, also Zero Energy Consumption.
 

How About the Maintenance of the E·pas? It is Better than the Regular Battery in Which Way?

No, it doesn't. Due to the characteristics of lithium batteries, the lithium ions will crystallize after the power is exhausted, thereby blocking the electrode rods, resulting in a decrease in the electrolyte and a decrease in the activity of the lithium ions.
Above that is the main reason for the shortened life of lithium batteries after repeated charging and discharging. The correct way is to charge in time, don't wait for the power to run out before charging.
The E·pas power regeneration technology will keep the lithium-ion activity at any time which will increase instead of reducing the battery life.
