there has been multiple threads on flashlights for biking/mtb, you might want to read up on those threads…
The S2+ is a great choice to wet your feet, it may prove suffice for your use, or not, only time and usage
will tell… FWIW, I’ve tried the S2+ and many other lights, both on bar and helmet.
You’d mentioned MTBing…
Since you’ve already ordered the 2fish mount, try it first. But the Fenix mount is rock solid and all those who
use it rec it:
~$12, use coupon code “alb10” as posted by M4D M4X
For helmet mount, I use strips of velcro, you might need to adjust the angle depending on your helmet.
For the handlebar light, I prefer a very wide floody beam and use DCFix. You can get it cheapest here:
Lastly, depending on how bumpy your trails and how fast you go, the light on the handlebar may rattle to its
early demise. Has happened to me. My handlebar light is sealed with potting material. If you’re buying from
MTN you prob could ask to have it done as well.
Have fun, be safe.
