The FLASH LITE 2.0 is the entry point into EUNORAU's FLASH long-range family. It keeps the family's signature modular triple-battery system and 20 × 4.0 fat-tire commuter look, but pairs it with a lighter rear-hub motor and a simpler single-speed drivetrain, landing in a more accessible spot between long-range capability and overall weight.
A 52V 750W rear hub motor with 92 N·m of torque, a standard 52V 16Ah battery with optional second and third batteries for up to 220 miles, an 80mm EXSHO STRONG-DH fork, hydraulic disc brakes, and a two-person plush saddle make it a capable everyday city rider.
Key Features
-
52V 750W Rear Hub Motor: Up to 92 N·m of torque for responsive starts, carrying additional weight, and handling moderate hills.
-

The Longest Range E-bike
The FLASH electric bike comes with three battery options. If a single battery isn't enough, riders can add a second or a third battery. With all three batteries on board, the EUNORAU FLASH is said to achieve a range of 220 miles (354 km) on pedal assist 1. This long range makes it one of the longest traveling e-bikes in the industry.
As Electrek put it, that is enough range to do the Cannonball Run between Los Angeles and New York City with just 12 recharges.
EXSHO STRONG-DH Fork
The front suspension fork features 80mm of travel, compression adjustment and lockout. It effectively absorbs most of the jarring bumps and shocks, especially on complicated and rugged routes, reducing your tiredness and allowing you to ride faster.
Battery-Powered Front Light
Light the path with the front light powered by the bike's battery. It can be turned on and off on the handlebar control pad. The headlight is bright enough to make night riding much safer and more enjoyable.
Two-Person Plush Saddle
The plush saddle can accommodate a single rider or a companion for a laid-back cruise. Two riders, one e-bike: with the 52V 750W motor, the extra weight of a passenger is no problem.
Integrated Brake-Activated Taillight
The taillight has a sleek design that integrates with the battery box. This simplifies the structure and enhances the look. When not manually activated, the taillight illuminates automatically upon braking, enhancing safety and visibility.
EUNORAU GO App Connectivity
In addition to the intelligent LCD display, the EUNORAU GO app lets you sync information. It offers calorie tracking, trip records, social networking and OTA updates.
Hydraulic Disc Brakes
The hydraulic disc brake set with 180mm brake rotors is sensitive, but provides efficient and ample force when braking. When riding in harsh conditions, the brakes are swift and can be relied upon to ensure your safety.

What motor does the FLASH LITE 2.0 use?
It is powered by a 52V 750W rear hub motor that produces up to 92 Nm of torque. The rear-drive system provides responsive support for starting, carrying additional weight, and handling moderate hills.
What battery comes standard with the bike?
The standard configuration includes a 52V 16Ah main battery. Riders can also choose an optional 52V 21Ah second battery and a 52V 17Ah third battery for additional riding range.
Can it really go 220 miles? Is that enough for daily commuting?
220 miles is the theoretical maximum with all three batteries installed on the lowest assist level (PAS 1); actual range will vary with rider weight, terrain, assist level, and throttle use. For daily commuting, the standard single battery is more than enough for most weekly routines — add a second or third battery only for longer trips or to avoid frequent charging.
Are all three batteries included, or are they optional? Do they add a lot of weight?
Only one 52V 16Ah battery is standard; the top-tube 21Ah and down-tube 17Ah batteries are optional add-ons. Buy based on your actual riding range — extra batteries add weight, so there's no need to get all three for short daily commutes.
20 mph top speed sounds slow — is that a limitation?
20 mph is the standard limit for Class 2 e-bikes, which generally lets you ride without registration or a license in most regions (always confirm your local regulations). If you want a higher top speed, it can be unlocked to Class 3.
No rear suspension — will it be comfortable to ride?
The FLASH LITE 2.0 is a hardtail; cushioning mainly comes from the 80mm-travel front fork and the fat tires themselves, plus an extended saddle. That's plenty for everyday city riding and light bumps. If you regularly ride on gravel or rougher trails, consider the fully-suspended FLASH 2.0 instead.
How do I choose between FLASH LITE 2.0, FLASH AWD, and FLASH 2.0?
Tight budget, mostly city commuting on decent roads: FLASH LITE 2.0. Frequently ride on sand, snow, or steep grades and need more traction: FLASH AWD (dual-motor). Want full suspension comfort and more power: FLASH 2.0 (mid-drive).
