What's your opinion on the bike light? How is the mount? So many bike lights have promising specs but have terrible mounts.
I've had it since it came out in September and love it. Until the recent cold and wind I ride for exercise 4-5 times per week 30min or 6 miles per outing on generally crappy city streets (Lots of bouncing and hills).
The mount is the best I've used and I've had a few over the years, from the crappy Amazon specials to some from dedicated cycling companies that should know better than put out the garbage mounts they have. Apparently, the mount has some go-pro inter-functionality that is important but I don't know anything about go-pros so can't really comment. I can say that it doesn't jiggle around, is very secure, and looks like the hardware is quality. I sort of wish you didn't have to rotate it to get it in and out because I mount it next to another light and have to be mindful of the order I attach and remove them, only a minor annoyance.
The light itself is fantastic. From what I can tell, you get the full 1500 lumens the whole runtime (no step downs), something many non-bike lights, even from olight, don't do. Battery life is good. I get 1 hour of full high (two rides) and it doesn't usually get in to where the red indicator comes on (20-11% remaining power). I doubt you get the 100 minute claim on full, especially in the cold, haven't tested it though. The strobe is very good, I do wish you got the full or at least more lumens in strobe, the light is certainly capable. I do use the strobe to help cars see me if my ride starts late and the sun is starting to come up. I really like that the battery is big, usb-c, and can be used as a power bank to charge other things. Also, the recharging port is placed properly so you can run the light off a portable power bank if need be.
I've got another capable light that I run along side the olight that is put out by a cycling light company that gets many things wrong where the olight gets them right, including putting the charging port on the bottom of the light so you can't use the light while it is charging (the mount on that light is trash too).
The olight RN1500 is a collaboration with magicshine, and you can get the same light under their brand but with less lumens. I've come to really rely on the olight. It is on the spendy side but considering the Lumens, features, quality, and that the company really backs their products, I think it is well worth the price. Plus, it is actually a really good stand alone flash light as well.
Edit: also, it isn't massive considering the battery and lumens you get.
