❌ CONS: What’s BAD? 🛑

- Real Range: Expect 60–80KM depending on rider weight, terrain, and wind (not 120KM) ⚠️.
- Customer Support: Mixed feedback—slow responses, warranty claims can be frustrating 🕒.
- Assembly: Claimed “85% pre-assembled,” but manual is unclear and frustrating for beginners 📖❌.
📱 LCD Display & Features: Is It User-Friendly?

The ENGWE Engine X comes with a basic but functional LCD display (not a premium color screen). Here’s what you get:
✅ What’s Good? 🟢
- Speedometer (current & max speed) 🚴♂️
- Battery Level Indicator (5-bar system) 🔋
- Odometer (tracks total distance) 📏
- Pedal Assist Level (PAS) Selector (1-5 levels) ⚙️
- Headlight Control (toggle on/off) 💡
⚠️ What’s Missing? 🛑
- ❌ No Bluetooth/App Connectivity (unlike premium e-bikes)
- ❌ No GPS/Navigation (just basic stats)
- ❌ No Backlight Adjustment (hard to see in direct sunlight)
Verdict: “A simple, no-frills display—gets the job done but lacks smart features.”
⚖️ Legal Status: Is This E-Bike Street Legal?
The ENGWE Engine X has a 250W motor, which makes it legal in most regions, but laws vary. Here’s the breakdown:
🇪🇺 Europe (EU/UK) ✅
- Legal without license: 250W motor, max 25 km/h (pedal assist only).
- Throttle restriction: In some EU countries, throttle-only mode is illegal (must pedal to engage motor).
- No registration/insurance needed (classed as a “pedelec”).
🇺🇸 USA (Varies by State!) ⚠️
- Federal law: Allows 750W motors (but ENGWE’s 250W is underpowered for US standards).
- State laws differ:
- California: Legal if under 28 mph (but 250W is too weak for that).
- New York: Throttle e-bikes banned unless pedal-assist only.
- Not ideal for US riders—better to get a 500W+ model for American roads.
🇨🇦 Canada
- Legal if under 500W & 32 km/h (ENGWE fits this).
- Throttle allowed up to 20 km/h without pedaling.
🇦🇺 Australia
- Legal if 250W max & 25 km/h (ENGWE complies).
- Throttle banned in some states (must use pedal assist).
🚨 Key Legal Notes:
- 250W is weak for hills—may struggle in steep areas.
- Throttle mode may be restricted (check local laws).
- No license needed in most places (but helmet required).
Verdict: “Great for EU/UK/AU riders, but underpowered for the US market.”
⚖️ Speed & Legality Certificate: What If You Exceed 28 KM/H?
📌 Quick Legal Summary:
Here’s what’s allowed for electric bikes in most countries (like Europe & the UK):
🔹 Max Motor Power: 250W (like the ENGWE Engine X) ⚙️
🔹 Max Speed: 25 KM/H (pedal-assist only) 🚴♂️
🔹 No License/Insurance/Registration Needed ✅
➡️ They’re legally considered “regular bicycles.”
⚠️ But What If You Go Over 25 KM/H (e.g., 28 KM/H or more)?

It’s no longer a bicycle in the eyes of the law.
🛵 It’s classified as a light motor vehicle or electric moped in many countries.
🪪 Requires:
- Driver’s license
- Registration 📝
- Insurance 💸
❌ It’s illegal to ride such bikes on public roads without proper documentation in most of Europe!
🚨 What Happens If You Modify Your E-Bike to Go 28 KM/H+?
In Europe and the UK 🇪🇺🇬🇧:
🛑 It’s illegal on public roads without registration and insurance.
💰 Heavy fines (e.g., up to €1,000 in Germany).
📄 Points may be added to your driving license if you repeat the offense.
🇺🇸 In the United States:
Some states allow up to 28 MPH (≈45 KM/H) under Class 3 e-bike laws.
✅ Requirements vary by state:
- Max motor: 750W
- May require insurance or license plates in states like California or New York.
🇨🇦 In Canada & 🇦🇺 Australia:
Top speed allowed is 25–32 KM/H depending on the province/state.
⚠️ Over the limit? It’s considered an automated vehicle.
🔍 What About 750W E-Bikes (like some American models)?
- In Europe/UK: ❌ Illegal unless on private tracks or areas designated for such use.
- In America: ✅ Legal in most states with a max speed of 28 MPH (45 KM/H).
The Difference Between 250W and 750W:
- 250W: Legal and good for flat areas, but less powerful on hills or rough terrain.
- 750W: Much more powerful, great for steep hills and rough trails, but requires a license in Europe.
