Video Summary - KEKURANGAN DAN KELEBIHAN MOTOR LISTRIK POLYTRON FOX 350 | Review Motor Listrik- Randy Waluya Nugraha

Product reviewed

Polytron Fox 350 electric motorbike (review after ~1 week / ~350 km of use).

Unique points mentioned (pros/cons + user experience)

Disadvantages / shortcomings

No clock on the speedometer
- The reviewer wishes the speedometer included a time display (useful even if you wear a watch).
Creaking sounds from the windshield
- More audible on uneven roads, especially without a helmet.
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).
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.
Front structure visibility
- The reviewer can see the front spar from above, suggesting a missing/removed cover/hole.
Creaking/vibration during low-speed traffic jams
- At around 7–8 km/h, the reviewer reports vibration and heaviness reaching toward the front handlebars.
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.
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.
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).

Advantages / strengths

Hazard/turn-signal sound feature (toggleable)
- With hazard lights enabled, there’s a sound; the reviewer says it can be turned on/off via procedure/menu.
Auto-off behavior when using the side stand
- If you forget to turn it off, waiting a few minutes on the side stand can shut it down automatically.
Improved seating position (main upgrade vs predecessor)
- More comfortable with thighs sitting lower and legs stretching more.
- Reviewer height: 171 cm, with comfort noted especially when placing one foot down.
Strong power / acceleration
- The reviewer calls it “fast enough” with good acceleration compared to other electric bikes in its class.
Top speed (mode-dependent)
- S mode: max 95 km/h
- D mode: max 61 km/h
Practical storage / trunk
- Plenty for daily office needs. Examples packed include:
  - charger, casing, cloth, extension cable, flip-flops, raincoat
- MCB note: the reviewer says you must turn off the MCB before washing.

- Charger output: 84V, 10A
- 0 to full charge: ~5–6 hours
- Example remembered by reviewer: 124 minutes charging → about +38%
- Charger power: 860 W
Battery rental system (key value proposition)

stiff rear suspension
some rough plastic finishing

missing clock on the speedometer

Who it’s best for:
