Full disclaimer I’m not 100% this is going to work. I found a Benchwheel pulley with same tooth count. It comes with two pulleys but I have the single motor version Liftboard. From my understanding the companies have some sort of relation. The pulley is the correct pattern for abec style and look to work with the current Liftboard belt. This is all theoretical. But I’ll report back. I just found the same pulleys I ordered on eBay on Amazon with next day delivery. Linked wheels and pulleys below. Will report back once I get a chance to try and install everything.
