A moped is defined by its paperwork, not its engine. In most of Europe it means 45 km/h, an AM licence, and a vehicle you can ride at sixteen.
The UQi GT is built to that definition rather than around it: 45 km/h, AM class, two seats, 227 kg of load capacity.
227 kg is the number that makes it useful
Load capacity is what separates a moped that can genuinely carry a passenger from one that legally may. Two adults and a bag is comfortably inside 227 kg.

Many electric mopeds at this price quote a figure around 150 kg, which means one average adult and nothing else. If you have ever given someone a lift home, the difference is not academic.
45 km/h top speed; 60 km of range on a charge.
1500 W maximum power with a FOC vector controller.
227 kg load capacity across two seats.
CBS braking splits effort between front and rear discs.
EBS regenerative braking recovers energy on the overrun.
The UQi GT is not trying to be a motorcycle. It is trying to be the 50cc scooter people actually buy, without the two-stroke and the annual service.
Where 1500 W runs out
On the flat, 1500 W gets a UQi GT to 45 km/h quickly enough to hold its place in traffic. Two-up on a hill it is working hard, and you will feel the speed bleed away.
The 60 km range assumes a single rider. Carry a passenger regularly and plan on noticeably less — as you would with any moped, electric or not.
Who it is for
City riders on a moped entitlement who need to carry someone. The AM classification means younger riders can use it, and NIU's app, anti-theft system and 360° lighting are the kind of details that petrol mopeds at this price never had.
If you have a full motorcycle licence and a longer commute, NIU's own MQi GT is the faster and more sensible purchase. The UQi GT is for people the licence rules put in this bracket.
