Not ridden or even seen an EQ in the flesh but after 2 favourable All City ownership experiences I really fancied one for a 29er based flat bar road bike itch I had.
In the end I decided to do the financially sensible thing and convert a bike I already owned (a stanton sherpa) to what I had in mind for the EQ. It's the dogs dangle. The sort of bike that excels at nothing, but does everything pretty well.
It feels rock solid/tight, tanks along the tarmac, but also handles fireroad and #nogravel but I've also taken it round my local xc singletrack (bedgebury) and whilst the slicks lacked cornering confidence it was still fast and above all fun. I've still got the suss fork, risers and 650b+ wheels/tyres for it so I can convert it between hybrid and mtb modes fairly easily.
If that's the sort of thing you had in mind for the EQ I say go for it. My frankenstan is far and away the most versatile bike I've owned.
