Hello There

I’m located in the nyc area and will like to share some pictures of my builds.

First of all, glad to see all the interest on the eBoard movement and to see sites like this and endless-sphere.com share so much knowledge and promote this wonderfull captivating and intoxicated passtime that we all enjoy.

Due to temperature coming back to normal ( Cool ) in the northeast have not tested the range but the speed is on the north of 45 mph. i’ll be switching the bushing to improve stability at high speed and will try to max it out. attached is a screenshot of a test run using Strava app.

so Range and max speed TBD.

This board is really nice, in love with the flex of the deck. the wheels can run over little chiguaguas and not even notice it, just a little hard on the rough surfaces, coming from pneumatics is understandable :-).

i’ll post some videos (now that i have a Gopro) :slight_smile: when the temperature allow it.

very sweet!

More pics of your custom motor mount would be awesome too :wink:

I’m sure there are people on here who’d love to see how you made it.

3

the mount for the eMTB just use a 2-1/2 " 3/16 steel flat bar and bolted to the brake holes to make a base and attached to this bolt a pair of arm made of Aluminum Angle 6061-T6 Structural 6" (A) x 3.5" (B) x 0.313 (t) cut in 2.5 inches long

can get it on this link http://store.buymetal.com/aluminum/angle/6061-t6/aluminum-angle-6061-t6-structural-6-3.5-0.313.html

Great idea putting that reflective tape on your motors!!! I may borrow that idea. How do those MBS skate wheels feel?

5

Nice ,Go for it !!

p.s. I borrowed the idea of the series to parallel DPDT switch on my second built from your old threat on endless-sphere :wink:

6

AWESOME BUILDS!

I really like the reflective stuff you put on the motor barrel

THOSE BIG BLACK “all terrain” WHEELS ARE REALLY NICE TOO!

how does the 42 inch vangaurd deck feel? im in downtown chicago and im building a board with a 38 in deck. Originally i ordered the 42 but was too big in my opinion… now i kinda regret it haha

8

@barajabali the deck really nice plenty of room for my stance

9

What flex is the board? Does it work fine to have components mounted over the middle? Trying to do some research of sensitive it will really be in the end on my flex 3 board.

10

@massy The board is flex one

For the battery enclosure what I did was to fix the bolts closer to the front truck, because the displacement of the deck in this area can be neglected and for the 2 bolts by the motor side of the enclosure I just tight then enoug to hold the enclosure in place but to allow for a small displacement of the. For this I use threat lock.

This can be seen on some of the pics , the hole for those bolts are a little bit long.

11

call me crazy but i just see that battery box tearing apart eventually. What kind of wear are you seeing on the box’s bolt holes? the battery case is bridging what looks like a serious flex point.

12

The wear is intentionally to allow for displacement of the box due to the flex.

I’ll update in the future about the enclosure.

13

@longhairedboy Read the comment just before your comment. :slight_smile:

14

yeah i guess the comments didn’t make much sense to me so i got more specific in my question. Keeping the bolts loose is going to allow sliding, which is your intention, but what i’m interested in is if you have seen any tearing as the bolts reach their maximum slide position as determined by the box’s bolt holes.

I’m doing something similar on my current prototype as an experiment where the box bridges the flex point but because of the bolt pattern the box itself is allowed to flex slightly outward. as the deck bends downward. I’m not leaving any bolts loose to allow sliding, however. Just allowing the center of the box to flex outward slightly. I have experienced no irregular wear around the bolt holes.

Which is why i was asking specifically about your wear patterns on your box around the bolt holes.

15

Hi there I have not seen any sing of wear on the bolt holes, the wear around the bolt on the pic is intensional for the box to move.

The bolt are not loose on the motor side, they are adjusted enoug to allow horizontal displacement only and I use threat lock for them not to become loose.

Them wheels on the second board! Gotta get me a set of those!

17

the reason i’m so interested in this (other than being interested in what everyone posts in general because i love this scene) is because i’m actually attempting a build on a 38" vanguard flex 1 for a friend of mine. Its an informal complete i’m doing as a favor.

you don’t want to know what i’m going to do to the space cell to get it into a more boosted like layout, but it’s going to happen. i hope everyone here likes battery porn.
