The Eunorau Flash is a long-range commuter e-bike built around a 52V 750W rear hub motor delivering up to 92 Nm of torque and a top assisted speed of 20 MPH. The Flash stands out in the e-bike market for its triple battery capability - a standard 52V 16Ah battery can be supplemented with an optional 52V 21Ah top tube battery and a 52V 17Ah down tube battery, extending total range up to 220 miles on pedal assist level 1. A 80mm travel EXSHO STRONG-DH front suspension fork with compression adjustment and lockout handles urban and varied terrain with ease. The plush extended saddle accommodates a single rider or a passenger. Hydraulic disc brakes, integrated LED lighting, and a BC182 LCD display with app connectivity complete the build. The Flash is UL2849 and EN15194 certified and supports riders between 5'2" and 6'4" with a payload capacity of 440 lbs.
