Hi community!
Being in the process of building my first electric longboard I found myself facing the challenge of getting pulleys for my build. Fortunately I have found a reliable local shop selling steel HTD-3M (boosted boards use this size) and HTD-5M pulleys with number of teeth ranging from 12 to 72 for belt sizes of 9mm, 15mm and 25mm. The bore size for the motor pulleys is 6mm, for the larger pulley it is 8mm, so they do require some modifications. They don’t come with keyways nor grub screws, but this is a DIY forum Motor pulleys cost 8 euro shipped, wheel pulleys cost 17 euro shipped, for combined shipping send me a message! PM me if you are interested! Thanks!
