Just wanted to share my electric longboard build, in effort to help others out and ease the frustration of finding all the components and simplifying the build. This build gets me up to 16 miles on a charge and a top speed of 28 mph. I’m an average sized dude and found the power and acceleration more than sufficient.
I hand-made all my mounts, however I would not recommend it. It’s not worth your time, and much easier to simply buy them from Enertion or Alien drives. All was made with aluminum plate in my garage. No lathes, mills, or CNC’s, just simply made with hand tools, drills, and taps. The drive hub was made with thick Home Depot washers that I drilled out, and the gear hub drilled too. I simply used the Orangatang wheel holes as a drill guide. I used long 6mm bolts & nuts through the hub. I also had to drill a large hole in the gear hub to allow clearance around the truck. Also grinded off some of the truck for more clearance. FYI, do not get 50° trucks because they are way too unstable after about 15 mph. Definitely get 44° trucks, and some and some angled risers to play around with. Also, a long rider can really beat up your feet and legs. Get some rubber shock pads or rubber risers to smooth out the ride. I used Khiro 1/8 rubber risers and Khiro 60a rubber angled risers. PS, All other vibration pads are junk and wont work. Khiro’s are real rubber. For the electronics enclosure, I mounted it with mounting tape and screws to the bottom. The components are mounted with double sided foam mounting tape. I cut a hole in the aluminum enclosure, then placed single side adhesive foam tape around the inside edge. This sealed perfectly on top of the speed control fan. I also drilled some small holes on both ends of the enclosure for air to enter. The battery enclosure was fastened to the deck in the same manner.
As for the radio, I used a HobbyKing GT2B, which worked great, but found it to be a little klunky and it can’t fit in your pocket. So I tore it open and slimmed it down to just the electronics (see the pictures). Basically I just had to solder a wire to the battery, then mount everything together with mounting tape, then wrap it all in duct tape. Much smaller and pocket sized. FYI, originally I excluded the antenna, but after a few rides I realized it is necessary because the radio will occasionally pick up WiFi interference and drop out. Beware, it’s a small fragile solder connection, so covering the solder joint in epoxy or hot glue is a good idea.
A cool addition I added was the voltage gauge which I mounted within the front nose of the board. It’s nice to know how much charge you have left so you can make it back home.
Below is a list of the components I used:
HobbyKing GT2B radio $25
HobbyWing EZRUN-Max8 speed control – From Hobbywingdirect.com - $130
Tacon Bigfoot 160 (245 KV) – From Hobbyparts.com $65
36 tooth wheel hub – ShopPolyBelt.com - Item #: P36-5M-09-6FA - $20
16 tooth motor Pulley – ShopPolyBelt.com - Item #: P16-5M-09-6FS - $10
Belt – 52 tooth - SDP-SI part # A 6R25M052090 - $16. However I’d recommend a longer belt. 52 teeth made it difficult to fabricate my mounts.
Ehlers – Mad Deer longboard Deck – (39.75” X 9.75) $70
Caliber II Trucks – 50° (should have got 44°) $60 (I had to use angle risers to get back to 44°)

Hope this helps people out. Good luck on your builds.
: Quanum 2.4Ghz 3ch Pistol Grip Tx & Rx System (works great, only thing annoying me is that i need to speak with security in shops about what i have in my pocket, and evade crazy drivers on the road who things that im carrying a gun)
