Electric Mountainboard V2

thingiverse

I'm stoked to share my latest design improvements for my electric mountainboard. Although probably unnecessary, I used 100% infill for mount body and 20% for the rest. What's new? I swapped out the chain for htd5 belts, making the board significantly quieter, slightly more efficient, and a breeze to assemble. Another game-changer is the new pulley, which is 3D-printed and designed to fit the wheels and trucks perfectly, eliminating speed wobbles that plagued my old board at high speeds. The new design looks way sleeker in my opinion. Here are the parts I used: Hardware: * A mountainboard (obviously!) + https://www.mbs.com/boards/10101-mbs-colt-90-mountainboard-constellation * 12-tooth htd5 motor gear with 8mm bore (2) from eBay * Htd5 500-teeth 15mm wide belts (2+spares) * Idler bearings 625ZZ 5x16x5 (4) * M4 bolts 5cm (2+spares) * M4 locknuts (10) * M5 locknuts (32) * M8 locknuts (6) * M4 washers (10) * M5 washers (32) * M8 washers (6) * M5 threaded rod ~26cm (5) * M5 threaded rod ~30cm (1) * M8 threaded rod ~20 cm (2) * M4 bolts 6cm (10) * M5 bolts 8cm (2) Electronics: * Vesc (2) + http://diyelectricskateboard.com/diy-electric-skateboard-kits-parts/vesc-the-best-electric-skateboard-esc/ + http://shop.faradaymotion.com/shop/18-electronics/4-vesc-motor-controller/ * Turnigy SK3 192kv (or any other 12s brushless ~200kv motor) (2) + I got this one: https://hobbyking.com/en_us/turnigy-aerodrive-sk3-6374-192kv-brushless-outrunner-motor.html + Here's another option: https://www.aliexpress.com/item/Maytech-6374-190KV-e-bike-electric-motor-longboard-motor/32666982968.html?ws_ab_test=searchweb201556_7,searchweb201602_4_10017_507_401,searchweb201603_1&btsid=bac5c47f-cf08-4292-b0fc-a6355c35e43c Battery: * 30x 18650 Samsung 25R cells * 10x 18650 Cell Battery Holder Box from eBay (3 slots) Remember to grab some wires, a charger, and connectors for the batteries if you don't already have them. I also recommend an antispark XT90 between the batteries and electronics or as a loop key. There will be a video at some point, but not before 2019.
