Amazing spec! I look at this and think, this is what I thought the Kenevo SL would have been. Kenevo and a dual crown fork is what has come to define what it is. Don't get me wrong, I LOVE my Kenevo but can't help but wonder what it would be like with this set up - of course the motor would have...
Good call and happy to help. 2cm over is a lot. I think the S3 will be your sweet spot. When you get the right size, it changes everything. Your arms won't be tired from all that weight on them and most importantly, you'll have balance on the bike which is a little helpful for jumps ;)
