So this is just another basic vesc 6, chain drive emtb. for those of you who have seen my thread on my MUD MONSTER know that it is riddled with design flaws and poor execution.
the thread- MUD MONSTER, Scrub mountain board | vesc 6 mkIII | 1:7.5 two stage chain drive
don’t get me wrong MUD MONSTER kicks some serious ass, but after upping the motor amps it really put the drive train to it’s limit. so from the ashes/ spare parts arose Harbinger a hopefully reliable mtb to bring good times and good vibes. anyway to the build
i had a spare trampa 16ply deck lying around and some over parts to build off.
so i started by drilling holes in each of the sprockets to mount them.
then centre drilled some 12mm en8 steel so i could centre a hole saw on the sprocket
and then set up a pretty janky setup to dill the centre
it also saved a bunch of weight
milled some standoffs to mount the sprockets
i drilled some 8 tooth sprockets and grinded down some cap head m4 screws to use on them
got everything loctited in place
and here are some crap pics, i’ll take some nicer pics soon after a test ride
i took the bindings and vescs off MUD MONSTER while i work on it’s big brother ‘Iron Giant’
i’m running sk3 192kv sensorless on a 1:5 9inch wheels and the start-up is shiiiiit, soon i’ll probably setup encoders, the whole setup without battery is 14.8kg
