Update – This was originally publish in 2012 so some of the tech and whatnot has changed

UPDATE: Since the protoype they’ve made a number of improvements on the designs, reworking the speed controller,  the motor mount and the controller. They’ve put a lot of time and effort in to R&D, so while I’ve put in some indicative costs of parts their is obviously all the trial and error, expertise, marketing and profit you pay for. Another update here.

Boosted board 2 update here

So I’ve been looking over these electric boards for a while and saw the Boosted board on kickerstarter which looks like a nice set-up.

While I haven’t seen one in the flesh or had the chance to ride one I thought I would do a bit of a tear down of what goes into it for anyone interested in maybe making their own. So looking over the video and kickstarter page I’ve got the following:

So lets look at the basic components of the longboard setup.

  • Loaded Vanguard deck – $175
  • Bear Grizzly 852s – $49
  • Otang 80A In Heats $55
  • Jehu bearings $20 (or you could get Bones Reds)
  • Bolts $10
  • Total$309

Or you can get one from loaded boards complete for amazon for $281. Loaded Vanguard Flex 2 42″ Complete Longboard With Paris Trucks, Orangatang Wheels

A nice setup. However I’m a little unsure about the wheel choice but I’ll get to that later.

Now we get into the electronics which are are RC car/plane parts.

  • Brushless motor x 2 – $40. Now its hard to see what type of motors they have on this thing but we’re looking at relatively small brushless outrunner motors designed for RC planes. From Hobbyking  you’re look at about $20 each for a 35mm motor
  • To control the motors you’re going to need an electronic speed control – $40 Something that can handle a decent amount of current that will be drawing from the batteries on startup. If you look at Hobbyking your looking at the $35 mark.
  • Wireless receiver – $20. Now in the promo video they make a big deal about the custom designed controller but in essences its a simple controller with forward and break (speed controller handles the breaking aspect with brushless motors). If you look at Hobbyking again they sell a RC car controller for $15 and that includes a  channel for steering not just accelerate and break. http://www.hobbyking.com/hobbyking/store/__10608__Hobby_King_GT_2_2_4Ghz_2Ch_Tx_Rx_.html Also a link to another electric skateboard project where the guy tears one of these apart to make it smaller.  http://www.endless-sphere.com/forums/viewtopic.php?f=35&t=37230&start=15

Finally the battery – $50. LiPo batteries are pretty cheap and given the specs they’ve given on the range they’re not planning on putting in many.

Now the hardest part of the design. Mounting the engines and the drive train. Now in the video gives a few hints. Basically its rivetted into the middle of the back truck. Out of the end of the motors looks like a pretty standard RC airplane extension with a custom cog. And a custom cog on the wheel. And a dual belt drive.

So estimating the custom motor mount $40

Custom cogs x 4 (motors and wheels)- $30

Two belts – $20

For someone looking to create their own electric skateboard this is going to be the hardest part. Mounting those motors to the trucks and cogs for the wheels. You not going to find anything off the shelf to fit or if you do you’re going to need to modify quite a bit. So we’re talking metal lath and/or welding. A pair of tin snips and soldering iron isn’t going to cut it.

Finally you have bolts and plates that go through the wheels into the cog. $20

Now this is This is where I question the wheel choice.

“Orangatang in heat” wheels are a solid wheel. Hence all those screws that hold the drive cog to the side of the wheel are drilled straight through the plastic of the wheels and bolted the other side. What does this mean? You’re not going to be able to rotate the wheels for uneven wear.

Now if you went for something like the Abec11 Flywheel.

Boom! Holes for fixing the cog already.

Check out the peeps at Evolution boards for their Abec 11 setup. http://evolveskateboards.com.au/products/the-evolve-electric-pintail-board-with-abec-11s (not rolling with Abec 11 I see:( )

So what is the components dammage for such a set-up. About $571. Now this doesn’t take into consideration postage, packaging, labour, customer plastic covers and all the work behind the customer parts and electronics.

Is it a good buy at the price of $1200? I don’t know. But it looks awesome to ride and it is by far one of the nicest electric skateboard set-ups I’ve seen.
