Electric bikes (e-bikes) are booming! 🌍⚡ They promise eco-friendly commuting, cost savings, and no sweat uphill climbs. But does the Jasion X-Hunter-BW deliver? Let’s break it down BRUTALLY—no ads, just facts!

📊 Key Specs:
- 🔋 Battery: 48V 13Ah (Removable) → 🟢 Good capacity!
- ⚡ Motor: 250W (Peak) → 🛑 Weak for steep hills! (Competitors offer 500W+)
- 🚀 Max Speed: 25 km/h (15.5 mph) → 🟢 Legal in EU/US (no license needed).
- 🛞 Tires: 20″ x 4.0″ Fat Tires → 🟢 Great for sand/snow!
- ⚖️ Weight: 28 kg (61.6 lbs) → 🛑 Heavy! Hard to carry upstairs.
- 🌍 Made In: China 🇨🇳 (Designed & Assembled) → 🛑 Budget build quality.
In the UK, electric bikes (E-bikes) with a power of up to 250 watts are allowed, provided that:
- The electric assistance cuts off at a speed of 25 km/h (15.5 mph).
- They do not have a throttle (must be pedal-assisted only).
Bikes that exceed 250 watts or can go faster than 25 km/h without pedaling are classified as “Speed Pedelecs” or “E-mopeds” and require:
- Registration plate.
- Appropriate license (e.g., AM or A1 motorcycle license, depending on speed).
- Insurance.
- Approved helmet.
🛑 Is a 500-watt bike allowed?

- If its speed is limited to 25 km/h and it is pedal-assist only:
- It may be considered legal as a standard e-bike (though 500W exceeds the usual limit, so specifications should be checked carefully).
- If it exceeds 25 km/h or has a throttle:
- It will be classified as a light motorcycle (L1e-A) and will require registration and licensing.
🟢 Advice:
- Check the bike’s classification under UK/EU law (usually stated in the manual or on a label).
- Avoid non-compliant bikes (especially those imported from outside the EU).
- For 500W bikes, it’s best to consult the DVLA or local transport authority.

🟢👍 PROS:
- 💰 Affordable Price: Cheaper than RadPower/Aventon.
- 🔋 Removable Battery: Easy charging at home/office.
- 🚲 Full Suspension: Smoother rides on rough roads.
- 🛞 Fat Tires: Stable on sand/mud (adventure-ready!).
- 🔌 Foldable Design: Saves space (but heavy!).
🛑👎 CONS:
- 📉 Weak Motor: Struggles on hills (250W is entry-level).
- 🏗️ Build Quality: Plastic parts feel cheap (rattles over time).
- 🔋 Range Claims: “25 km” is optimistic → Real-world = ~18 km (throttle-only).
- 🔧 Limited Support: Few service centers (DIY repairs likely).
- 📱 Basic Display: No GPS/app connectivity (competitors offer smarter dashboards).
🚴 Jasion X-Hunter-BW: Throttle vs. Pedal Assist & Battery Drain Issues? ⚡🔋
Let’s break down how this e-bike rides and whether it kills the battery fast! No sugarcoating—just facts.
1️⃣ Throttle Mode (Ride Without Pedaling) 🎮
- 🟢 YES, it has a throttle! → You can ride without pedaling (full electric mode).
- ⚠️ BUT: The 250W motor is weak for throttle-only use:
- Slower acceleration than 500W+ bikes.
- Struggles on hills (may need pedal assist).
- 📉 Battery Drain: Throttle-only = FASTER battery drain (real-world range ~15-18 km vs. claimed 25 km).
2️⃣ Pedal Assist Mode (PAS) 🦵⚡
- 🟢 7-speed gears + 3-5 PAS levels (varies by model).
- 👍 More efficient battery use (extends range to ~20-25 km).
- 🛑 Motor cuts off at 25 km/h (EU/US legal limit).
3️⃣ Does Throttle “Choke” the Battery? 🔋💀
- 🛑 YES, if abused!
- Throttle-only = 2x faster battery drain vs. pedal assist.
- Uphill throttle use → Battery drops drastically! (250W isn’t strong enough).
- 🟢 Solution: Use PAS + throttle combo for balance.
4️⃣ Real-World Range Test 📊
Mode | Claimed Range | Real Range | Verdict |
---|---|---|---|
Throttle-Only | 25 km | 15-18 km | 🛑 Weak motor drains battery fast |
PAS (Level 1-3) | 25 km | 20-25 km | 🟢 Best for efficiency |
PAS + Throttle | – | 18-22 km | ⚠️ Middle ground |
5️⃣ User Complaints on Battery Life 🔋👎
- “Throttle-only died after 12 km! Useless for my hilly commute.” – Mark (USA)
- “PAS works fine, but motor feels underpowered.” – Lisa (Germany)
🚨 Final Warning:
- 🔋 Battery Killer? Only if you use throttle recklessly.
- 💡 Pro Tip: Use PAS on flats, throttle only for short boosts.
- ⚡ Upgrade? If you need longer range, get a 48V 15Ah+ battery (sold separately).
📢 Bottom Line: This bike can ride throttle-only, but not efficiently. PAS is smarter!
🆚 Competition Comparison (2025):
Model | Motor | Battery | Max Speed | Price | Verdict |
---|---|---|---|---|---|
Jasion X-Hunter | 250W | 48V13Ah | 25 km/h | $799 | 🟡 Budget, but weak |
RadRover 6+ | 750W | 48V14Ah | 32 km/h | $1,999 | 🟢 Powerful, but $$$ |
Aventon Aventure.2 | 750W | 48V15Ah | 45 km/h | $1,699 | � Best value |
👉 Jasion loses to rivals in power & features but wins on price.
🗣️ Real User Opinions

🧐 Final Verdict: Should You Buy?
✅ Buy if:
- You need a budget fat-tire e-bike for flat terrains.
- You’re okay with basic features and no frills.
