NIU KQi Air and Segway Ninebot MAX G2 live in the same premium commuter space. Still, they feel like two very different answers to the same problem. One is light, sharp, easy to carry, and loaded with smart features. The other feels sturdy, calm, and ready to eat long, rough commutes without drama.
If you try to choose between them only by numbers, the decision feels messy. So this guide walks through how they behave in real life. You will see how they stack up on weight, power, range, comfort, safety, smart features, and who each one actually fits.
NIU comes from the smart moped world, and you can feel that mindset in the KQi Air. It looks compact and clean, yet it does not feel like a toy.
Key things:
So KQi Air makes sense for riders who want a real commuter scooter that still feels easy to lift, fold, and live with every day.
Segway’s MAX line already had a strong name. MAX G2 takes that base and makes it more grown up.
Key things:
So MAX G2 aims at people who treat the scooter less like a gadget and more like a small daily vehicle.
KQi Air looks simple in a good way. Clean lines. Tight panels. Hidden cables. The finish feels closer to premium hardware than rental fleet gear.
The folding latch feels clear and quick. Once folded, the scooter stays slim and short. It slides next to a desk, behind a door, near a café table, or in a trunk without fuss.
The low weight changes the routine:
Plus, the light chassis makes slow speed handling smooth in crowded spots. You can roll, pivot, and park without feeling clumsy.
MAX G2 stands tall and serious. The stem is thick. The deck is big. Suspension parts and big tires fill space. It looks like it means business.
The folding joint works well, and the scooter folds in a straightforward way. Then the weight reminds you this is not a grab and go feather. Lifting it into a car or over a step is fine. Carrying it up several floors many times per week feels rough for most riders.
Build quality feels strong. Nothing feels hollow. Parts sit snug, and the scooter gives a dense, durable impression.
If you often carry the scooter, pick NIU KQi Air. It respects your back and your hallway.
If you rarely carry it and prefer a larger, more planted feel, pick MAX G2. It acts more like a compact electric vehicle than a fold and forget toy.
KQi Air pairs its light body with a responsive rear motor on a 48 V system. That combo makes it feel quicker than its numbers suggest.

Choose MAX G2 if you stack many kilometers, ride faster, or want to forget about range stress most days.
KQi Air has no suspension, yet it does not feel sketchy when used on the right surfaces.
You get:
On smooth paths it feels light, direct, and satisfying. On broken roads you feel more hits, so you start to pick your line, slow a bit, and ride smart. For many downtown areas with decent pavement, it feels like a good fit.
MAX G2 leans into comfort.
You get:
That mix smooths speed bumps, patched asphalt, and random rough spots. At higher speeds, the scooter feels relaxed and steady. Long rides feel easier on your legs and wrists.
Pick KQi Air if your roads look decent and you enjoy a light, nimble feel.
Pick MAX G2 if you ride long, hit rough surfaces often, or just want the softest and most planted ride in this matchup.
KQi Air backs its speed with a solid safety setup.
You usually get:
Stopping power matches the scooter’s weight and speed well. It feels controlled, not vague. The lights and signals help other road users read your moves.
MAX G2 pushes safety further, in line with its role as a bigger commuter.
You usually get:
The drum brake stays consistent in wet weather and needs less service. With suspension and mass, the scooter stays planted during hard stops.
Both scooters take safety seriously.
Pick KQi Air if you want a light scooter that still checks all key safety boxes.
Pick MAX G2 if you ride faster, ride in the rain, or want traction control and suspension support when you brake hard.
KQi Air brings a strong connected experience.
Common features include:
So security and control feel built in, not bolted on. For a scooter this light, the alarm and lock tools help a lot.
MAX G2 relies on a mature app many riders already know.
Common features include:

Pick KQi Air if NFC, alarm features, and detailed tuning in a light scooter sound appealing.
Pick MAX G2 if you want straightforward controls, wide support, and tracking tools that match a scooter often parked outside or in shared racks.
KQi Air feels like a quality product, yet its low mass still rewards careful use.
Key notes:
So if you avoid harsh impacts, bad potholes at full speed, and deep water, it holds up well as a daily commuter.
MAX G2 leans into heavy duty use.
Key notes:
So it works for riders who ride often, ride in many conditions, and expect the scooter to take hits now and then.
Choose KQi Air if you want a light but serious build and treat your gear with some care.
Choose MAX G2 if you expect long term, high mileage use, rough patches, and wet days baked into your routine.
Both brands back their products with formal warranty and service structures, with details that vary by region.
NIU:
Segway Ninebot:
So in many regions, Segway offers an easier path to local support. In key cities, NIU coverage feels strong too. It makes sense to check local service points, response times, and exact warranty terms before you buy either one.
Go for the KQi Air if:
So each day you feel the low weight, and you do not feel like you gave up real performance to get it.
Go for the MAX G2 if:
So each ride feels smooth, planted, and ready, even when the route or weather is not kind.
Both scooters are strong choices. The better one depends on how your days look, not just on spec numbers.
Pick NIU KQi Air if you feel every extra kilo, move through buildings, and want a light scooter that still rides like proper commuter gear.
Pick Segway Ninebot MAX G2 if you ride far, ride often, face rough roads or hills, and want comfort and stability to stay high even when the trip is long.
Once you match the scooter to your real routine, the decision becomes simple.
