Hello all, looking to make a low profile build on a smaller board (~30 in) that I will mainly use for short commutes which need an portable board that is light and subtle. Also looking to keep the budget low and around $300 hopefully. This will be my second build so I have some experience but would not say I’m an expert yet.
I want to use hubs for this build to keep with the low profile theme, and more specifically 70mm hubs to keep the weight down and to also be able to use a pair of 70mm wheels and truck I have for the non-hub side of the board. I know it is generally not recommended to use cheap parts but I am not looking for high speed or torque and don’t plan on forcing this board up massive hills or anything.
I’ve narrowed it down to 3 options below:
Banggood DC 36V 450W Hub Motor Kit For Electric Skateboard Longboard Part (Dual 70mm Hubs assembled with trucks),
I like this because the hubs already assembled with trucks, don’t have to worry about compatibility issues. I’m worried about buying general hubs and if I would be able to mount them on any generic trucks.
Banggood Dual Esc Substitute (or from eBay appears to be the same one):
Not really looking to spend big on a dual vesc, it seems like these are okay from some other forum posts I’ve read plus the reviews. I plan on just using 6s lipos as well (I’m about 150lbs so don’t need a ton of torque). The hub motors say they are rated to 36V, but I assume it doesn’t hurt to do 6s as opposed to going over the limit. It seems like the esc will be the bottleneck either way since its max power is 290W whereas the hubs are 450W.
Cost: ~$200 (with banggood coupons)
Aliexpress Hubs x2 70mm Hubs + Aliexpress Trucks
Use same dual esc substitute as option 1. I like that the 70mm hubs here are rated for 24V, I’m just worried about the truck configuration. It appears that to mount these hubs you stick the end of them into the slot on the trucks then put those little screw covers over them. This seems a little sketchy to me, what is preventing the hubs from just sliding out the sides? Is it just friction? Or is there some mechanism within those slot covers. I was hoping someone had used these before and could explain.
Option 3: Full kit from aliexpress https://www.aliexpress.com/item/2018-New-DIY-Dual-Drive-70mm-83mm-90mm-180W-250W-350W-Electric-Skateboard-Hub-Motor-Truck/32862636181.html?spm=2114.search0220.127.116.11a53644aq9IoO&ws_ab_test=searchweb0_0,searchweb201602_1_10065_10130_10068_10547_319_317_10548_10696_453_10084_454_10083_10618_10139_10307_537_536_10902_10059_10884_10887_321_322_10103,searchweb201603_57,ppcSwitch_0&algo_expid=941950ce-4762-460c-b72b-4c4f40e0896e-9&algo_pvid=941950ce-4762-460c-b72b-4c4f40e0896e
I like that this is all together, but the motors seem a bit weaker from the specs. Also this is slightly more expensive then the other options.
Options 4: Dual 70mm Maxfind hubs from aliexpress
Same dual esc as option 1. This is the cheapest option and the motors seem okay for the price, just worried about mounting the motors to generic trucks. Will these just work with any square shaped axles? Has anyone tried this before.
Would appreciate any advice, thanks!
