Hi! Nerd here – a fan of urban mobility who values reliability, ease of use and fair performance. This time I tested i9 Max: powerful 500 W scooter with large tires, robust design and interface Smart AppBelow is my review, with measurable data and user experience.
Technical inspection
Motor: 500 W brushless, three speed modes; allows up to 30 km/h (22 mph)
Battery: 36 V, 10 Ah (~374 Wh); range 30–40 km at moderate speed
Tires: 10″ honeycomb, tubeless, puncture resistant, with protective fluid
Suspension: double (front and rear) for comfortable driving on uneven surfaces
Housing: steel frame, folding mechanism Click-Lock, load capacity up to 120 kg
Water resistance: IP54 – protection against splashes and light rain
Screen: LED display – shows speed, battery, driving mode
Bluetooth / Smart App: MiniRobot app with locking, speed settings and driving statistics
My experience
Acceleration and speed
Through three modes (eco, normal, sport) I reached a stable 28–30 km/h in the highest. The engine responds immediately, climbing up to 20% slope no problem.
Reach
Driving on flat asphalt + easy to use app – one charge leads to 38 km, which matches the official data. On climbs and higher speeds, the range is reduced to 30 km.
Driving comfort
Honeycomb tires + front and rear spring damping provide a smooth ride even on paved or gravel surfaces.
Maintenance
The construction is simple, it folds quickly, the use of tire fluid is minimal. Reliable even after rain; only the use of IP54 means avoiding extreme humidity.
Advantages
500 W motor – acceleration up to 30 km/h, driving on slopes
10 Ah battery – up to 40 km range in ideal conditions
Solid tires – no worries about punctures
Double suspension – comfort on uneven terrain
Smart control via app, with graphic displays and locking
Robust construction, load capacity up to 120 kg and quick folding
Disadvantages
IP54 protection – only suitable for light rain, not for heavier water
Higher weight load – capacity fluctuates at 120 kg
Brake system is electronic + disk; not the most sensitive in wet weather
Comfort worse compared to pneumatic tires – less vibration absorption

Who do I recommend the i9 Max to?
Suitable for:
city driving, up to 40 km distance per day,
transportation over mixed terrain (asphalt, pavement, macadam),
users who want reliable power, uncompromising tires and application support.
I don't recommend it:
in case of frequent driving in heavy rain or puddles,
users who require hydraulic braking or pneumatic tires for maximum comfort,
tistim, ki iščejo ultralahke skiroje (<12 kg).
