Need advise or opinion please read. You guys are the experts. Not me.
I am building a new fat tire hi power off road machine. My goal is to have enough power to tackle most terrain including
Florida sugar sand. I want to be able to get deep in the woods for hunting and possibly pull a hog out with a small trailer.
The motor is a Mxus rear direct drive rated up to 5000 watts. The battery is 20s 4p 26650 3.7v 5000ma cells 72v nominal
40a bms continuous 120a maximum. The controller is a " vector " chinese 24 mosfet 80 amp maximum output. It is questionable.
I have not powered it up yet. It is huge and heavy 300 mm long and about 2 kgs plus. I will try this with your advice without a cycle
analyst. Just wired directly with a simple digital volt meter and thumb throttle. No power switch. I wired the little red main ignition
wire from the controller directly to the controllers main red positive. Power on off is just a simple connection directly to battery with Anderson
50 amp connectors. On the bike I did install a Grin Technologies torque arm. I installed a front gas / air adjustable suspension shock and
seat post shock with cushy seat. Frame steel hard tail looks strong heavy and heavy duty. Brakes are questionable mechanical disc. If brakes
are crap I have been reading about Magura MT4. At least for the front. Any suggestions on brakes. The tires are knobby 4.5 in Fat Tire .
My previous build had all the above except the bike was a diamondback with 2.5 in balloon Maxxis tires,
controller was only a 40 amp and it did not have enough power thru deep sand. The controller would get hot and shut down. Let it cool down
and go again. It rode about 35 mph safe and comfy on open trails and about 45 mph on the paved road . It had linear pull brakes with big
kool stop mountain pads never an issue it could lock em up at any speed. Disc brakes are much more fickle and trouble. Not available
on fat tire frames / front air gas shock setups.
Mainly looking again for pulling power not speed. Let me know .Thanks
