Another handlebar-related mount option is to tap the top of the IQ-Cyo heat sink and mount that to a Garmin out-front mount. @jimmythefly suggested it here: Small bikes that aren't horrible compromises - #74 by jimmythefly
I set my wife’s bike up this way. She’s on 650b wheel with a <100mm head tube, so it basically puts the light in the same place as a fork crown mount would. My version doesn’t look as nice as JP Weigle’s, but it worked well.
Using:
- Barfly garmin/gopro mount
- Lezyne-GoPro adapter
- loooong M4 bolt that runs all the way through the light, heatsink, and adapter
