Once again, this is speaking in regards to the general population of indoor cyclists, but no. It is better to have a narrower Q-Factor rather than a wide Q-Factor. What this does not mean is that a bike should shoot to have as narrow a Q-Factor as possible. People’s knees don’t naturally bend inwards while riding a bike, so this is a major problem with those spin bikes that have Q-Factors in between 110mm and 140mm. The pain and injuries that can be picked up from those sorts of Q-Factors are certainly a major problem. However, the general rule of indoor bike manufacturing and design is that the Q-Factor should be smaller in order to reach that ideal range of 140mm to 170mm. Since this is the range that the majority of users will fit comfortably into and by extension want, that is what should be aimed for. That is why a narrow Q-Factor is better than a wide Q-Factor, though too far in either direction is certainly not ideal.
