I guess we will now have to wait for a few real-life user reports..
While this is not a surprise, I am surprised by the many very strong opinions and convictions here based on the pictures alone. Some of which I can understand (f.e. worries regarding sand/dirt in the Helix'es), but some also which honestly I completely fail to understand (f.e. questionable welds??)
Personally, I will keep my strong opinions for when I have had enough time riding the Helix extensively in different situations. Or at the very least, for after serious and extensive reports from people who did do just that..
