you are correct on needing wide spread light on night mountain trail due to lack of "street lamps" inside jungle/mountains. nice light and batt pack mod, btw, only use reputed and high discharge 18650, me and few friends Blow up several cheap batts (my friends into vaping mods) i think with that 4x t6 cree, it draws a lot of power
all: sadly those mtb spotlight also at the same time not road legal(luckily malaysia dont enforce this) a proper road light MUST HAVE light CUT OFF line. that why all the branded one are expensive because to be legalized in some country like German, France.

for joy riding at night, seriously ride only on well lit area, incase of anything bad happens, people "sees" you. and u get help faster.

mind sharing the info on ur helmet's light? thanks

alamak, cant understand Chinese 

how many lumens? price around rm60??

i found this one. looks kind of the same
will find an adapter to attach to my helmet

You should do bulk order hehehe
Question, let say(eg) one can ride with 26t chain ring and 36t chainring (or 44t) with cassette cog that result with same gearing ratio, would riding at smaller or larger chainring is more comfortable?

I ride mostly on road (some light uphill and some hard uphill), plan to upgrade but not sure to get double chainring or single chainring setup. Need advise from experience user.

(Not sure if relevant, I can do 27-30kmh on my 14kg 29x2.1 bicycle)

good info bro, i like elaborate explainations. so dont need to asks few times. i was thinking this conversion too. but then again, since now doing much onroad so save a lil bit budget now hahaha.
btw, the goatlink thingy is a first for me. thanks!
