2018 bikes were sold out. Q45 will be re-stocked on April 24. The reasons that I don't own Q45 are: (1) the bike weight of 15+ Kg is too much for me. I am a skinny man weigh 56 Kg. (2) I want the head tube angle at least 78 degrees for fork with 40mm offset (84 degree with straight fork). I want a bike which I can push with one hand at the seat and the bike will go straight. The problem with low head tube angle is: the front wheel will flop until it hits the frame. If you don't want your Q45 front wheel to flop when you park the bike, make a bike stand which will lift the rear wheel at least 10" above ground, that is, to make the head tube nearly vertical.
