Hello
Welcome
Good info thanks
Yeah I saw his YouTube video where his replies to comments were a tad nasty and defensive. The ones you mentioned look really good and simple to use. Thank you!!!
Thank you Frame, can’t believe how many people have replied already! .

That really sucks about the carbon fibre, ugh. Would it still be fine if I applied the carbon fibre to the deck and enclosure, but cut out a rectangle where the enclosure sits underneath the deck so the signal would just pass through the wooden deck?
I”ll stay clear of Boundmotor then. Such a shame because lots of them seem so good to newcomers like me :(.
Just forget about carbon fibre. It looks pretty, but it conducts electricity and is opaque to radio. Use fiberglass instead.
Again, fiberglass. Completely forget carbon fiber exists.
I’d recommend you make the enclosure so that instead of bolting to the deck along its perimeter, just hang it from two bolts on the front and two bolts on the back. Put butyl tape (bubble gum consistency) all around the top edge, inside the bolt holes and lay a sheet of flat rubber on top. Put a cutting board on top of the rubber with some weight on top for an hour to squeeze the butyl tape, then bolt to the deck. This way, you have completely sealed from water ingress. It doesn’t even matter if the top of the enclosure is flat and the deck is concave, the tiny gap makes no difference this way.
So you have like a “tub” hanging off the bottom of the shortboard whose only hole is a charge port, and you’ve sealed the backside of that. No other holes, you should be able to toss that in a lake if you want to.
Motors-
I really like direct drives but understand they are still relatively new and there was quite a bit of controversy around the first generation axils breaking/bending. Please can people let me know there thoughts on distributers quality of them etc. I have seen torque boards, but not only are they very expensive to replace if they break, but after contacting them they said they cannot be ridden in the rain. The other two linked below said there DD’s are waterproof but to be careful and bearings will need replacing.
I would skip direct drive entirely and go for belt or gear or chain drive, collectively called “satellite motors”.
Direct drive aren’t very servicable and the motors are too close to the ground, and you can’t get those nice high-torque gear ratios that maximise range and fun.
Battery -
I posted on Reddit and someone said the two linked below are not reputable and should not be trusted.
I would definitely not buy anything from Boundmotor or eskating dot eu. The second one I have personal experience with, and is terrible. The first one is run by Jedboards. Look them up.

The sooner you forget about carbon fiber, the happier you will be.
It conducts electricity, it blocks radio, and fiberglass is better for esk8 building in almost every way except “cool factor” and “looks”.
cut out a rectangle
sure, it might work that way, but fibreglass is still the way to go. if u really like the looks of carbon fibre, u can slap on those fake carbon fibre car vinyl, they don’t cost that much if u need to wrap a shortboard
good to newcomers
we used to have elofty, but it has also disappeared. do u have to use DD tho? belt / gear drive are also pretty good.
Check out these daily commuters for some ideas
a build thread for The Green One, an electric commuter skateboard My tenth esk8 and seventh DIY-esk8 has been born. This is a commuter board for moving around town, going to work, grocery shopping, and is friendly to trains and shopping carts and hauling cargo. It’s not too heavy and has a handle on the nose. It has lights so I can be seen. It’s a sister board to the Blue One, the Black One, and the Red One. [IMG_20200507_043554067] hand-built waterproof 10S 14.5Ah Li-ion 42.0V battery | lo…
The Red One an LEV build by b264 [20210115_203302] This is probably the 4th complete rebuild of this skate, the only original parts at this point are the deck, griptape, and handle. It’s the oldest in my fleet of five shortboards. (But now also the newest, ironically) [20210115_203208] So what’s my favorite thing about this board? Welp this is my only shortboard currently running TKP. I guess it’s not my favorite thing, but it definitely rides differently because of that. It’s real “di…
Bigfoot an LEV build by b264 [20201215_013925] This build has been in some sort of “done” state for a few weeks now, but I’ve been tweaking things and I think this may be close to the final form. This board is a little different. Firstly, it has some absolutely enormous TB130 wheels. These things are truly massive. Let’s compare to some 60mm OJ III Hot Juice wheels so the scale is apparent: [20201215_030923] So what’s my favorite thing about this board? That’s definitely the ride. It …

esk8supply is still around, haven’t seen them active in awhile
Don’t buy @esk8supply ESCs, they are sold illegally and as such are illegal to resell, and your support is worse.
The problem with belt drives is that they take up lots of room that I’m hoping can instead be filled with batteries. Plus I thought DD motors held up better to water? On the clearance and performance side, it’s only going to be a city board so shouldn’t go through any tough terrain plus it’s not a performance board so I don’t need screaming motors. A little more powerful than my current exway Wave motors (max power 1000 watts) is just fine for me

Yes, I know. I thought the same thing.
After many tries though, I’m just gonna have to recommend you skip over direct drive. But do what you want They just aren’t as good as they seem on paper.

All BLDC motors will be mostly waterproof out of the box, as long as you don’t use sensors. Water will shorten the bearing life but you can change the bearings. Motor hall sensors seem really prone to failure for some reason, and if you haven’t personally went in there and waterproofed them yourself, then there’s little chance they’ll last very long. Even so, way more reliable to simply not use them at all. Only connect the 3 big phase wires.

This is my exact usage also.

Use a really wide deck. Look at the Blue One or the Green one I made, those decks. I don’t know how wide the Boosted Mini deck is, but it looks narrow.
Also, going single drive on the rear heelside can save room too. Look at Damon’s Rona Roller for some more ideas.
I finished my Landyachtz dinghy. The deck was a gift from @NullReference but everything else I had laying around. I know @b264 is going to appreciate this. [image] The enclosure is made entirely from leftover bondo from Walmart. it’s kind of terrible but whatever. I sanded it for 649 hours and it turned out mediocre.

Although I’d strongly recommend a 6380 or bigger motor on a single drive.
In rainy conditions single drive might actually be safer than dual drive. When both rear wheels slide you will likely crash. When only one slides the other still keeps you straight. Downside is you often struggle to get any power on the road before it spins.
When I ride my dual drive in the rain I set one motor to only 50% power so one slides before the other. You might also consider rubber wheels with tread to help with traction.

I second all of this
It’s counter-intuitive but I much prefer single drive when it’s wet and slick.
Dual-diagonal would be better still, but on a shortboard, there’s typically no space for all that jazz.
I’m 3d printing my enclosure too. Welcome to the club!
