Assembly instructions were a bit minimal - didn't tell you to check the steering stem bolts which happening to be very loose. Lucky I checked.
The charging port is in the worst place, right behind the front wheel where it gets showered in debris and splashes from puddles. Of all the places they could have put it, that's probably the worst place.
The open triangle at the front of the foot deck needs covering it so your legs / pants don't get showered in debris and puddle splashes. The rear wheel cover / mudguard could do with going over the the tyre a bit further so your back doesn't get sprayed when you ride through a puddle.
The 40km distance is way off. I ( 95kg ) ride on pretty flat ground at 25kph, it can only do about 20km before starting to slow down. After 25km it's dead and I'm walking. I have to charge it before the return trip each time, not what I was hoping for. Could have bought a cheaper one and charged it each time.
The disc brake squeals really loudly. How can I fix that?
The tail light / brake light is good how it goes brighter and flashes when you brake. The bell is really good.
