Endless loop really is the place for ebike stuff. I’ve experimented with moving my esk8 parts including one of the older 4.10 hardware VESCs over to a bike (using Stanton’s parts for the motor mount and wheel pulley), but so far mixed success. I haven’t run into issues with burning out the VESC yet (on a bike), but I have followed Tom’s stuff for a while here and he did mention he blew at least a few VESCs and did eventually start using FOCBox (maybe it was vesc6 I forgot but pretty sure he got upgraded for free).
I printed and molded the parts for the wheel pulley but unfortunately the tooth spacing doesn’t seem to be 100% correct. Same issue is present on the original 3d print as on the molds but I didn’t have a belt to check when I did the 3d print and assumed it would be good, so if you’re doing the 1/4 pieces would verify your belt fits snugly before proceeding to make the whole thing.
Aside from tooth spacing I ran into a couple of other issues (possible exacerbated by the imperfect tooth spacing). One of the other issues was if the pulley on the wheel isn’t 100% concentric with the wheel itself then there is some play as it rotates the belt gets tighter and looser (obvious in hindsight but didn’t really consider this as a major problem). To get around that one I’m using an idler on a spring load to keep some tension on the belt but allow it to move to compensate for the lack of perfectly concentric wheel/pulley. Last problem I ran into is needing to adjust the motor mount so that it would be able to be mounted on the particular bike I was putting it on (craigslist garbage mongoose bike for $45 to experiment with). Actually the last bit about the bike brings up another point, make sure the bike has a big enough wheel diameter so the motor doesn’t end up in the way of the wheel itself, I tried on a foldable cruiser someone gave me to try out but with smaller wheels the motor position ended up right next to the wheel (you want regular mountainbike or street bike size wheels, also street bike wheels are ideal, I think in terms of the bike a hard tail 1-by is ideal, see seth’s bike hacks on youtube for some good beginner tips on picking bikes in general etc.)
^ there’s a video testing my setup upside down, I was able to do a little bit of testing riding around before Chicago entirely froze over, but have been working on making my own skateboard wheel pulley design as an intermediary step to redoing the bike one (ideally so I can print it all in one go) but need to do the math etc. on gearing to see how that will work out… basically how much torque will I be sacrificing if I make it small enough to print on a 200x200mm bed.
I’d say if you’re just trying to get something working then going with a hub motor setup is a ton easier (avoid all the alignment issues and potential for belt slipping off in different directions and trying to avoid having spokes run into any of the motor mount parts, long story short alignment is more difficult than you think).
