The scooter is surprisingly well-built and looks much more substantial in real life than it does in the photos.
The frame, swingarm and springs are robust, and the overall construction is very sturdy – no play, no twisting.
The motor has a genuine, real-world power output of 800 W (not just a marketing ‘peak’ figure), and it accelerates confidently even when going uphill.
The 48 V / 20 Ah battery is exceptional for this price range, and its performance stability reflects this.
The suspension is excellent, with a long travel and massive springs that absorb even the roughest bumps effectively.
The display is large, clear and easy to read.
A major advantage is the height adjustment of the handlebars and their extra-wide design, which significantly improves stability and manoeuvrability.
I appreciate the range of settings – zero start, cruise control deactivation and speed unlock.
The scooter doesn't have regenerative braking or motor braking, which I see as a big plus because of the free-wheeling momentum when riding downhill.
The disc brakes provide excellent and reliable braking.
The footrest is wide enough to fit both feet side by side (unless you have feet like a Yeti).
In real life, it’s a proper little tank – it’s definitely not designed to be carried around for long, but to be driven.
The manufacturers deserve praise: In this price range, the K900 has no competition, partly because it is a legally approved vehicle for use in the Czech Republic, a requirement that the vast majority of grey imports from China do not meet.
I forgot to mention that the combination of the tubeless tyre and inner tube fitted to the scooter gives you a high-quality tyre and eliminates the risk of burping

long range (in practice 50-60km)
the speed limiter can be switched off
great suspension even when I ride on cobbles
it is not IPX-certified (so it is not waterproof)
cannot recover
The app I use to connect my scooter to my mobile phone could be a bit more sophisticated
