So I like electric unicycles which I basically regard as a revolution in personal transportation. They are quick, switch easily between riding and walking, and consume very little space. My Inmotion V10 served me well for 4000 km, but its limited range of 30km was getting me on my nerves, especially during summer times, where multiple charging sessions were needed during a day. But apart from that, I really enjoyed riding this thing.
Looking around for a new wheel was easy and yet very difficult. I wanted a recent 1500+Wh model, so that limited the choice between the KS16X and the Nikola. It took me months to decide between both. Both are very fine wheels, but the reports about the water- and dust inlet of the KS16X let me skip this wheel (someone remembers the waterproofing issues of the V10 some months after launch ? I really needed a wheel which I can occasionally drive through some rain without fear of having a brick few days later). Shame, I really really like the looks of the KS16X, definitively the better looking wheel of those 2, it reminds me of the Z10 with those fantastic LEDs.
I initially was looking at the Nikola+ 2100Wh, but put it down as I feared for the sheer weight (my daily commute has a fairly amount of steps). As the 100V 21700 model came it out with its double battery pack, it meant better stability and lesser weight, so I was sold.
The wheel performs marvellously : riding it feels like a magic carpet, and my range has been increased from 30 km to 70 on a single charging session. It's also super stable, with only a few wobbles at high speed, mostly due to badly positioned feet on the pedals. The most noticeable disadvantage is the stock CST tire, which has a nagging desire to stay upright, even when taking turns (the so-called gyro effect). This implies leaning horribly to the left or right (like on a motor cycle) which feels a bit eerie, especially at high speeds.
