Something about E·pas you may want to know


  • Q: How does E·pas work?
  • A: Ride faster, over 15 mph at PAS 0/1 for longer thanks to the energy regeneration tech that automatically charges the battery for 20% power as you ride. The intelligent sensor engage the E.pas system to regenerate 60% energy when you’re going down hill without energy consumption.
  • Q: Does E·pas disrupt the charging cycles of the battery?
  • A: No, it doesn't. Due to the characteristics of lithium batteries, 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. This 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. E·pas power regeneration technology is to keep the lithium ion activity at any time which will increase instead of reducing the battery life.



***The power assist system(E·PAS) features energy saving, power generation and long battery life. Our Engwe Engine and Engine Pro($1699.99/ In Stock) electric bike use E·PAS technology to optimize the motor and professional hardware. Under the intelligent control of E-PAS, seamless between driving and reverse charging can be realized.***
