I apologize in advance for the severe lack in pictures/videos. I was not expecting to make a build topic on this, as it is not an innovative build. But hey, thought I’d throw it out there in case anyone wants to do a TB build!
Thanks to Torqueboards for supplying everything but the deck and wheels! You rock
Aight. Where to start!
Oh yes. Probably the beginning.
A long time ago (2015) when I was a little squirt (17) I decided to build myself an electric longboard! So I did. And posted that build to instructables. Look over it if you want. Its a bit sad, and I really need to go and add a few paragraphs on why a single 5056 280kv motor is NOT the way to go It was all incredibly DIY though right down to the deck paint job, and I am proud that I was able to pull it off! It functioned. It looked beautiful. It impressed all my friends and parents and siblings.
But no amount of pride makes mediocrity, if not down right poor, any better lol. The ESC burned out on me twice, the motor could not take much of a grade at all, and the housing allowed water and dirt to get in.
So I decided to build a new and improved board with DUAL drive. Took me a few years and a better job, but with double the budget of the old build in my pocket, I felt well equipped to make a real go-getter. And holy cow I did. So much so that it hurts. Literally. (More on that later)
Over the course of two years, as my budget allowed, I started collecting items. Not having much time or money due to large college loads, and after the experience with my first board, I decided I wanted to go with PURPOSE BUILT parts. Seeing as the E-skate community was blowing up I knew there would be some quality parts out there I could use. Especially in the motor and ESC categories.
A deck off Ebay. 97mm Wheels. x2 TB 6355mm 230kv motors. x2 TB 7480 190kv motors A Torqueboards dual drive kit. x2 18T motor pullies (back when TB made those, rip) x2 36T Wheels pullies Pack of 9mm x 380mm belts x3 4s 16000mAh 10C Lipo batteries
Using these, I began to assemble my board over the course of those two years, making a few changes in the last weeks (Literally a month ago)
At that point, everything was looking alright. Unless you looked at the bottom of the board. (Here I was testing a single motor set up with this new motor to compare it to the single motor set up on m y old board. New size motor was IMPRESSIVE to me!)
Here I was testing one of the 7480 170kv motors. YIKES tons of torque!! (Note I moved it down to an 8s setup lol)
In the meantime, I grabbed some parts off Ebay, so I could do a thing I wanted to do with my old board; LIGHTS More on those at the end of this build topic! (If this topic is worth anything, its those lights lol)
Anyway, the batteries were just too big, and the C rating (which I thought would be offeset enough by their capacity) were just not working for me. So I bought a TB 12s4p battery.
And an enclosure, because up until then everything was ducktaped to the board
So I ordered those.
In speed tests I had done with my single drive versions of board, I KNEW I was going to be hitting a crazy top speed with dual. So I rightfully geared up. Kneepads, motorcycle torso protection, and a fullface helmet off Ebay.
In a fit of LED flue I also grabbed some EL wire and tricked out my helmet. For safety of course. It was a bit of a messy process. Epoxy was not the way to go. In all I used 3 EL wires. Two 2M bluewires, and 1 3M white wire. I threaded the battery-ends of both blue EL wires through holes I drilled in the ventilation holes at the back of the helmet. (Clearly my right drilling hole was my first )
And epoxied them around the helmet in a slick design
The white wire I strung out from the left temple joint of the helmet. I removed the plastic tab that covered the joint screw in order to do this. I was sure to cut more of a slot then a hole to ensure the helmet flip up would still function properly without pinching the wire. Hence the very bad looking hole. (20180921_161021|666x500 I was sure the plastic tab would still be able to snap back in place to cover up that monstrosity of a hole
. I had to wait for a 3-way split connector so I could connect all three wires to the power at the same time. Until then… Helmet Left side blue wires with the front of the helmet down.
And with front of the helmet flipped up.
White front wire!
That three way connector FINALLY came
Board/helmet picture time!
. Anyway, all EL fun and games over, I got my battery and a proper enclosure, and screwed it all together! Again, sorry for the terrible photos
Beautiful dual-drive! And working on some cheap racing stripes :)) Thanks TB for the enclosure!
Note the two LED strips.
Generally I was able to get up to 29mph on one motor. Acceleration felt a bit weak and I would and needed to give just the slightest kick from a standstill. (Sensorless) Breaking from 20mph to 3-5mph took about 6 seconds (which is quite a bit for road use) and at the end of the breaking period the break would feel pretty weak. So much so that I would usually footbreak.
I added that second motor in, and WOW. It makes a HUGE diffrence.
My top speed shot from 29mph, to somewhere probably in the 38-40s (I have yet to dare to try it thx to weak stock brushings I need to change out :I) My range went down about 3-4 miles. I no longer need to kick on acceleration (Sensorless) My acceleration makes my smile every time. I can beat any car from a dead stop at a stop light, and make it across the road before they catch up. (It also sounds strong, and no longer like a whiny motor is going to kill itself lol) Controlled breaking from 25mph takes about 4 seconds, and feels strong, firm, and stable.
My motors are noticeably less hot (if even warm) after a run vs when I was running a single motor. This probably goes for the dual VESCs too. I pull less amps per motor when accelerating. And can put down more breaking power whenever needed. The chance of my belts snapping and/or teeth slipping are REALLY REALLY low because they share the strain of all forces asked of them. Did I mention better breaking?
My confidence in boarding on roads aside cars has shot WAY up, and I am actually able to feel safer during the rides, which makes the whole experience much more enjoyable.
After tasting what dual motors feels like, I will never, EVER, EVERRR go back to single motor
Of course with confidence comes higher and more dangerous speeds. I do wear full head protection, along with motorcycle armor for my chest, back, and arms, as well as knee/shin pads. I also always wear jeans, and usually some sort of longsleeve (I prefer hoodies) I have taken a spill at 35~mph, and only came out with 3 little skinned spots on one inner elbow(I have no idea how they got there. My longsleeve jacket was completely intact), and sore outer thigh and ego. No blood at all.
FINAL SPECS: 35+mph top speed (can’t get there because speed wobbles. I need to go get some better brushings, and probably an anglespacer (Brushing help? There are so many different densities, shapes, and positions (front truck back truck ect) that I am just totally confused on how to actually make my board more stable at higher speeds.) 15 mile range.
I even added a small removable tailcarry in case I wanted to carry something! (I use this small bag to store the charger and a few tools and spare belt that I never ever E-board without!) .
The best part (aside from the great speed and performance) is the RGBW LEDs though
I wired them off a little step-down converted that is wired directly to the battery. I can control them wirelessly via an app on my phone. Any color I want (via a color wheel) Any brightness, and with the ability to synch with music I can also connect my Charge 4 and become a rolling disco party! Purple is my favorite color, so it’s usually set to that. Green is most visible at night though, so I will usually have it set to that when it starts to get dark.
My EL helmet is awesome, but its big and the epoxy holding the EL wire is not the best at connecting smooth surfaces. So, I went out and bought a 3/4 Bitwell helmet with a chrome bubbleshield. And I LOVE IT!!! The visibility is 200% better. It’s smaller and more compact, and weighs less. (Ignore the paper, setting up for a new spider-inspired EL display )
I love this helmet so much, that I even take it airsofting now (Along with my motorcycle gear). It beats wearing sweat-inducing goggles any day, and provides great peripheral vision too- almost as if I am wearing nothing at all!. Plus, it is the most unique helmet on the field (and road) for sure. So much so that I earned the nickname “Robocop” at that airsoft field.
Robocop loves his modded KRISS Vector!
Don’t bother asking why I have better airsoft pictures then e-board picures!
The helmet also self-clears fogging. There is a small gap where the bubble visor snaps to the helmet. When air rushes over this while I ride my board, it will clear any fogging that I may have created. Pretty niffty!
Thanks for reading this long drawn out post with no real rhyme or reason at all!
I will be adding (QUALITY) photos/videos of my LONGBOARD to this thread as I get them!
Stay cool, stay safe, stay awesome fellow dudes and dudettes!
