Build a longboard they said - It will be fun they said. And yes! it is! This is my first voyage into the world of longboards - electric and analog alike. The reason: 14km commute to work where the bike path is generally in excellent condition. Electric bikes are limited to 27,5 km/h which is a bit to slow for my taste. So - the idea of getting an electric longboard was conceived.
I work in a fablab so the thought of building the board from scratch (or at least getting some parts and putting them together) seemed appropriate.
Wheels I know that a lot of you guys spend a lot of time getting specific trucks and specific wheels for your rides but since I had very little knowledge I thought it best to get a set. I ordered a complete 90mm kit with dual hub motors, trucks, front wheels and ESC from Alien Power System. I’ve later found that those kits can be found on ebay but well… Now I have them. The most annoying thing was I have to wait for 5 weeks to get them - what to do?
Batteries While waiting I ordered 50 cells (18650 type) from nkon.nl. I chose some 30A Sony cells rated for 3120mAh each (https://eu.nkon.nl/rechargeable/18650-size/sony-us18650vtc6.html). The plan is to pack them as 10S5P but since I can’t charge a 10S pack I will do 2 5S packs instead. I know more charging time and less automated but Just for getting the board on the road this should work.
Deck Now for the fun stuff! I had 5 weeks to burn so why not try to design a shape myself? I had very little to go on The only picture of the trucks mechanical layout was a vague description with some inch measurements on. well, I tried and came up with a general idea. The overall length of the board is 1m because… it felt good when I looked at it.
I’m designing in Onshape and things got a little out of hand. Now I’m designing everything, from the battery mounts to the covers to the electronics bay. I will try and post pictures of all the parts as they finish on the 3d printers.
This is a rendering from last night.
