enclosure clearance

1/2"

@MarkVa1

think speed bumps and such will be an issue

This type of ground clearance wouldn’t let you get onto a side walk without scraping, they have a little 1/2" lip and often have bump strips for visually impaired… I wish you luck

[worldismine772]

would turning not be an issue too?

[ShutterShock]

Yes turning would also be an issue lol the corners of the enclosure would probably hit the ground

[MarkVa1]

Any recommended minimum for clearance?

[xatonic]

@MarkVa1

I’ll start them at 5 Amps with a 12S6P configuration.

That’s going to be pretty hard to make slimmer, I forgot you made a drop deck. Maybe you could route out the deck a bit to inset the pack? If you could layout your electronics in the enclosure it might be easier to see where you can slim it down

Probably atleast an inch for clearance, but that’s as low as I’d go

[glyphiks]

It depends how much your trucks lean.

I typically wouldn’t recommend anything less than 45mm

@MarkVa1

So is 1/2" ground clearance enough for a street riding board?

What’s an inch?

In vehicle engineering, there is metric, and there is metric. Convert FUB to metric.

@MarkVa1

So is [13mm] ground clearance enough for a street riding board? I think speed bumps and such will be an issue…

I think it’s not. But it’s not solely based on clearance, it’s also based on how far from the wheels. See this

@b264

Mentioning a number of millimeters IMHO doesn’t help, because it highly depends on wheelbase as well. Shorter wheelbases can have much less clearance and still be just as functional. A long wheelbase needs a taller clearance, or a clearance that’s arched in the center.

My goto test is I go find a speed hump local to me, one of the nasty ones, and I like the skate to just barely be able to roll over it head-on with me on top, without scraping (but a couple millimeters away). The shorter the board, the lower it can be.

@b264

Find a speedbump (speedhump) and roll your board over it (without standing on it)

If it comes within 5mm of it, it’s too low. Any higher than 15mm, is too high.

So what I’m saying is that it totally depends on wheelbase, longer wheelbase needs more clearance. But also, it depends on WHERE between the trucks you’re referring to. You need an arc of clearance. If it’s right next to the front or rear trucks, it can be closer to the ground. In the middle is where you need more clearance. And that’s assuming no flex. The arc needs to be exaggerated if the deck flexes.

When you roll over obstacles, curbs, and rough terrain, the further you are from the truck, the more clearance you need. So the longer the wheelbase, the more overall clearance you need if the bottom is flat.

Most of the times i dont want my enclosure lower than my truck axles.

[xatonic]

I set mine up like this

@b264

What’s an inch?

Inch

[ShutterShock]

This is my rule too, and even with it at that level, you can still scrape very easily.

My drop through hummie with DS on 110mm urethane, at its lowest points is just above the axle level and I scraped all the time. On Bergs, it’s pretty great clearance.

[krude_dancer]

what kind of trucks are those and how do they work

[b264]

Hey Andrew, why not add some constructive answers instead of trolling?

Just curious.

[MarkVa1]

That’s a good question. I’ll let you know if I ever get this thing out of my garage and on the street

[MarkVa1]

Technically he is correct, knowing is half the battle. . I enjoy the humor…

I thought I would have enough clearance but I didn’t take into account the thickness of some of the enclosure padding, the enclosure wall thickness itself… it all is adding up.

The deck is big, so I may mill some extensions that have less drop and spread out the battery to one level instead of stacked. Looks like a 10s6p will fit with the VESC and BMS on one plane…

Anyway - not the end of the world. Perhaps I got enamored with the dropped deck look? I’ll drink some wine and think about it…

As always, I appreciate everyone’s feedback and input!

[Bavioze]

With the 3 link trucks you can move up your center hinge, is that still possible with yours? (Steering will be increased though)

[MarkVa1]

I looked into finding a heim joint with a longer thread but that’s not going to raise it too much. I think I’m going to flatten the battery to one layer and go with a 12s4p. That should leave enough room for the VESC and BMS and add another .8" of clearance. Get’s me close to 1.5" of clearance total. Maybe raise the heim joint a little - maybe increase the thickness of the pad between aluminum extension and base plate… hopefully get me to the promise land

[davidbonde]

My expirience is that we need 50mm to have room enough for most everyday street riding. With 50mm you only need to be aware going up and down curbs and the like. Speed bumps and such are normally no problem.

Here the trucks are set at -1cm

You may have the lowest board but this picture also proved the biggest balls, skating that build in socks!
