---

Unique points mentioned (pros/cons + user experience)

Disadvantages / shortcomings

1. No clock on the speedometer

   • The reviewer wishes the speedometer included a time display (useful even if you wear a watch).

2. Creaking sounds from the windshield

   • More audible on uneven roads, especially without a helmet.

3. Rear suspension shock feels stiff

   • Compared to the Fox A, the rear shock still feels stiff.
   • Even with 1.3 kW mentioned (as noted by the reviewer), the rear suspension doesn’t feel comfortable.
   • Suggestion: consider an aftermarket shock (petrol-bike style).

4. Rear center/side stand issues cause sounds at higher speed

   • Sounds appear when riding fast over slightly uneven surfaces.
   • A community/group suggestion mentioned mitigating this by adding foam or swapping the standard parts.

5. Front structure visibility

   • The reviewer can see the front spar from above, suggesting a missing/removed cover/hole.

6. Creaking/vibration during low-speed traffic jams

   • At around 7–8 km/h, the reviewer reports vibration and heaviness reaching toward the front handlebars.

7. Rough plastic finishing in the drawer area

   • One specific plastic part feels rough/sharp.
   • Other areas so far are considered safe.
   • Extra caution is recommended for children who may grab the drawer.

8. Overheating error during a climbing test

   • On a steep incline (~15–17 degrees, approximate), the bike stopped initially in a scenario where the rider ahead couldn’t climb.
   • At the top:
     • The BDC became hot
     • A red light flashed
     • An error code E2.4 appeared
   • Manual meaning (as stated): belt/dynamic too hot; requires cooling/resting.
   • The reviewer says it returned to normal after about ~1 km of more casual riding.

9. Range/performance sensitive to real-world conditions

   • Even with a claimed range, real-world riding speed/modes and conditions significantly affect results (implied by the overheating event and later distance claims).

Overall verdict / recommendation

Recommendation: Based on the review, the Polytron Fox 350 is positioned as a strong-performing and feature-rich electric scooter/motorbike with comfortable seating, good power/top speed, and a low-entry battery rental system that suits beginners.

• stiff rear suspension
• some rough plastic finishing
• potential overheating/error (E2.4) during steep climbs
• missing clock on the speedometer

Who it’s best for:

• riders prioritizing comfort, performance, and practical commuting economics, especially those interested in battery rental rather than purchasing the battery outright.
