This being a work in progress, I’ll post updates as progress is made.
First off, I want to thank all members of the forum for support after I ended up donating the guts of my last board to an e-scooter. I especially want to thank @chris.hunt for his incredible generosity, as well as @mmaner and other anonymous members who helped me to both design this and purchase parts for it. I’ll find a way to repay you at some point (preferably when I can find time to go down to LA for a ride ).
Anyways, on to the actual build. This will be a dual drive EMTB with 63mm motors on @Idea mounts, running a 10s12p battery. The ultimate goal is to be able to both ride in comfort up the hills of SF and go camping in areas with trails using a trailer that I’ve built for this purpose. I’ve ordered and received many of the parts, some are still on the way. Here’s the breakdown:
Deck, Trucks, Wheels, Bearings, etc. - Arrived
10s12p Battery - Arrived (needs to be wired still)
5A charger w/ waterproof charging port - Arrived
Dual Focboxes - Arrived (from @Jreamer)
Handle - Arrived
Waterproof Focbox Case - Arrived
Mini Remote - Arrived (from @JLabs)
Misc. Items (Voltage meter, solder, xt60s, etc.) - Arrived
Trailer Hitch - Arrived (From @Wanderer)
Trailer - Built
Focbox Heatsink - In progress (Will be ordered soon from @JLabs)
Bluetooth Module - In progress (Will be ordered soon from @JLabs)
Motor Pulleys (11T?) - In progress (from @mmaner)
Wheel Pulleys - Will be 3D printed
Motor Mounts for ATS Trucks - On the way (from @idea)
Motors - In Progress (maybe @mmaner or @psychotiller)

I’m also considering adding a step down to usb for phone charging… anyone see a reason why that would be a bad idea?
hey man this looks awesome! i used a little usb down converter in my build so i could charge my phone and nano x off my lipos. it works great
here’s the link:
It sits in parallel with the vesc
Could you just confirm the mechanics of it? There is a ball joint that swivels left and right. Any fluctuation up and down? Would love to see your trailer once you get it done.
Pretty proud of the charger portion… it’s a two pin waterproof port capable of the 5A I’ll be putting through it. It’s also impossible to plug in backwards - an added bonus.
!
I’ve also taken the liberty of adding a standard laptop port to the end instead of direct connections, so that I can unplug and use another 10s charger if need be without issues:
All hot glue is just a precaution, everything has been properly done and heat-shrunk as always
One more thing…
I’ve been setting up the FOCBOX case and making sure all wires are put in the right place. Would anyone mind double checking this for me? I’ve never used dual drive, sensor motors, or FOCBOXs before and I am in no mood to make costly mistakes.
I’ll also need help setting up everything with VESC tool in dual drive (again, I have no idea how the master/slave settings work bc I’ve only ever used single drive), but that’ll come later. I’m sure @GrecoMan will welcome the opportunity to see me back in noob-land again
in vesc tool it’s super simple, it has options for what youre setting up
and tbh, i’ve only setup dual over can one time in my life, been way too scared to touch the settings since
