Good value for money, and great customer service
I purchased the KN front wheel motor with 250W in march 2025. I hesitated with the KF model but the KN is sufficient for the 9 km commute (I can charge at work if needed for the trip back). The delivery was very fast because it was shipped from Germany warehouse. Support was very useful and reactive through WhatsApp. They followed through all the steps. Installation was easy, there was a video on top of the instruction manual. The only issue I met is that my fork is with suspension, so while the fork dropout spacing was 10cm (minimum required) the spacing between the tube of the fork was a little shorter and the fit of the wheel motor was tight (the screw of the brake rotor touched the fork), fortunately the wheel came with spare flat head screw to attach the brake rotor so I used them instead of the round head screws and then no more contact with the frame. Regarding the motor, I am very happy so far (but I just used 3 days), I do a 9km commute with lots of hills and the battery can make it with around 75% left at arrival (I use the ‘commuting mode’). It can take me to 25kmph without problem even going up. I really like the throttle to help when starting, I feel it’s like a security feature because I can quickly get away from cars when the red light goes green. This product was recommended by a friend who purchased before and I am happy it all work as advertised.
