I think the solo overall looks nice. My thoughts on the front rim/tyre set up, is that having a bigger rim on the front with a narrower tyre than what you have with the 16" rim and tyre would be better, it will not turn-in as easy like when racing through the twisties, but at low speed it will feel/be more manoeuvrable and it will feel the crap road surfaces less, meaning that rough surfaces will not be transferred through the bars to your hands and arms as much with the large diameter rim compared to the small 16" rim.

As for the look, well it's purely subjective, just like art, however I do prefer the look of the bigger rim and thinner tyre. But as above, how does it ride?
