Q-factor on the Amflow?

[Asonetuh]

Anyone know what the q-factor is? I currently ride an Orbea Rise H15 with a q-factor of 177mm. that's the upper limit of comfort for me. genuinely thinking of switching to an eMTB with a lower q-factor like one with a TQ HPR50/60 or Bosch SX motor but the Amflow/Avinox is on the top of my list. unfortunately I can't find any specs.

This sort of helps. Same crank on Bosch vs DJI...

BOSCH CARB Q = 188mm ALLOY Q = 179mm DJI CARB Q = 178mm ALLOY Q = 170mm

Can the q factor be adjusted with spindle spacers?

These spindles use the ISIS interface. That has 1 degree tapered splines on the bottom bracket axle. The cranks need to fully bottom on the splines. Otherwise they will be loose and wear out as they move on the splines. Spacers would not only reduce the engagement with the splines but also make the engagement loose. Of course spacers would only make the Q factor wider. It's already wide compared to analog bikes. If you want even wider, then get some different cranks. Carbon cranks tend to have wider Q factor. You could add pedal washers but the safe amount to add (one on each side) won't change Q factor noticeably.

You can also try pedals with longer axles. I have seen some people who need special accomodations using pedal axle extenders but that risks cranks breaking. I don't know of a way to narrow the Q factor besides picking cranks with the least Q factor.

I wouldn't, but even then it would increase the Q factor, not reduce it. I think the OP wants narrower spacing. Overall though, the Avinox seems to be on the narrower side. Different crankarms have different offsets, and some may not provide adequate chainstay clearance. Also keep in mind that some sit differently on the ISIS splines.

Just measured with the OEM alloy cranks and it's slightly over 170mm. With my titanium crankarms it's slightly over 180mm
