Hey guys! I really want to get the build thread on my latest project out, because it is SICK!
I haven’t had a chance yet, because every spare minute I have, I’ve been on this rig!
So here it goes, here is “City Slicker,” and she is very happy to meet you!
So a couple of months ago, a buddy and I hopped on the Lacroix group buy https://www.electric-skateboard.builders/t/lacroix-board-co-wood-and-cf-deck-segmented-flex-carbon-fiber-enclosure-group-buy-completed/49051?u=sender
I wanted to do something a little different than just assembling essentially the same specced out board they are offering. Not that it isn’t AMAZING looking, but you know… Science… and DIY…
I was against going the Trampa route, and MBS trucks were surprisingly hard to come by for a bit there. So I bought some Surf Rodz RKPs 200mm with adjustable base plates (hopefully they are back on their site soon).
I got the trucks a good bit before the deck and sort of convinced myself that my whole idea of using the Surf Rodz set up on a Mountain Board was stupid and probably wouldn’t work for some reason or another.
So, I threw it all on my Bludgeon, Tico.
Tico is sick, and I was sold that I wasn’t even going to try to fix it to the Lacroix, because…well, I didn’t want to have to change that whole setup on the Bludgeon just to try something that probably wouldn’t work any way… oh well, idea scrubbed, I resigned to just waiting until MBS got more stock and I would just do something with that. No biggie.
Well, fast forward a couple weeks, and one of the sensors failed completely and it was annoying, so I took it apart, and preceded to have a little motor dilemma. So, damn, Tico, My Bludgeon is back on the bench. LAME
Then, destiny struck. It was a rainy day and I glanced over to that Lacroix, sitting there… helpless. With Tico down for repairs, “why not take the afternoon to see if this would work on the Lacroix.”
So the angles on the kicks on the Lacroix are 30degrees. I set the rear base plate to 15 degrees and the front to 25 degrees.
REAR: 30degree (kick) + 15degree baseplate = 45degree
Front: 30degree (kick) + 25 degree baseplate = 55degrees.
The holes on the Lacroix didn’t quite line up with my baseplate, so I had to drill them out a bit more. MBS trucks must just be ever so slightly different than normal Old School baseplates. No biggie.
So I mounted it all up and took it to the back parking lot and pushed it around with 107s.
OMG IT WORKS! It pushed like a damn dream, Carvey, but stable. Rolled over everything!
I made some 1/2" risers out of an old chopping block for these base plates while it was on my Bludgeon. I even routed out a channel on one to act as a sort of “Tunnel Riser”
The original plan was to put on some @psychotiller 6 shooters… But after riding it on the 107s and realizing with the 1/2" risers I had plenty of clearance, I decide to stick with the 107s.
I am putting those bad ass 6 shooters and some SZ TKPs on the Bludgeon… win fucking win.
So I built the battery myself, I don’t feeling detailing it particularly. It is a 10s6p with charge only BMS. I siliconed it into the enclosure for dampening. Worked a treat. Here are some build pics:
I noticed on my Bludgeon I would get some thermal throttling day time riding hard in this Alabama Summer.
I took a tip from @Deckoz to minimize this on City Slicker. I got a big 1/4" piece of aluminum stock and cut it to fit the enclosure. Then I thermal taped it down to the enclosure and thermal taped my FOCBOXs to the plate. This has DEFINITELY helped. I haven’t had any throttling issues even pushing it in the midday heat. It adds some mass and cools down fast as hell.
Of course I am using psychotiller motor mounts and his 200kv 6369 power plant with this 10s6p battery.
Here are the settings I have right now, but of course, I want to edge them up a little:
15/40 on Abec 11 107s
(On each Vesc):
70 Motor Max -55 Motor Min 60 Battery Max -14 Battery Min
This gets me right at 30mph, with a ton of torque. I want to change to at least a 16t motor pulley, maybe 18t, to trade a little torque for a bit more speed.
I also want to try bumping up to this:
75 or 80 Motor Max -65 Moror Min 65 Battery Max -17 Battery Min
Haven’t tried this yet, and don’t want to push it tooo hard. I would love to hear what you guys think is reasonable to push it to…

City Slicker gets 30 ish MPH top speed (going to change to get a bit more top end). And is Carvey as hell yet stable as fuck. What a combo!
I am still planning on polyurethane and glass frit, but I will do it some rainy day. I can’t stop riding!
Thanks for Reading!
(I will probably edit this later, as I typed all this on my phone, so I am sure it is full of errors and I am sure I have forgotten about things I meant to mention.)
So I finally got around to getting City Slicker looking pretty (and a few other little improvements)! I was planning on glass frit the entire time, but it took me a while to find the time to do it.
Also, I jumped on some @MoeStooge Street Wheels, which really add a lot to the look and ride feel of the board.
While the wheels do decrease efficiency a bit and add some extra rolling resistance compared to 107s, they are damn glue on the road. It is such a cool design, and I consider myself lucky to be able to grab one of the first 6 sets sold. Soon I will do a proper review, but suffice it to say, they are bad ass.
I am running 18/42 on the 120mm wheels. It goes about 34 mph or so, which is great for a set up like this.
Settings I am rocking with (per VESC):
Motor max: 100amps Motor min: -65 amps
Battery max: 55 amps Battery min: -20amps
Once again, 10s6p 30q. 200kv @psychotiller 6369 Powerplants.
This feels awesome. The whole board rides like it was designed to be like this. It feels like such a hybrid monster. Rolls over everything and feels super secure for fast carving. Truly it fits the namesake “City Slicker.”
I am beyond happy with how it turned out. Still kinda wish I did 12s6p. But, I have no complaints at all. She will still take off on you with the settings I have and mid 30s is a good top speed for this rig anyhow.
Thanks Guys, and Happy Building! Oh yeah, don’t forget to enjoy riding too!
