If you have no preference between two options, vote for both.
Since having an idler seems like a popular request, hereās a potential placement. Uses an 8x22x11mm bearing.
Depicted is a 20T and 40T gearing setup. These would be the maximum sizes available.
Thoughts?

The idler seems too deep inside, but then again I donāt know efficiency losses due to this. Maybe negligible. Another factor is stress on the belt.
Whether itās deep or not, the belt still has to bend around the same radius. AFAIK this would be the same resistance as any other 22mm idler system.

ALRIGHT! Final post for the night.
Cover that fits a 107mm wheel with 20T pinion pulley with 40T wheel pulley
Cover that fits a 90mm wheel with 13T pinion pulley with 40T wheel pulley
I went ahead and designed a belt cover. Because of the idler, the cover can extend all the way from the motor pulley right to the wheel pulley. Iāll eventually make a repository of all pulley size and wheel size combinations. All free to 3d print.
I actually really like this belt cover, itās the first design Iāve made that Iām actually satisfied with. It must be used with hubless motor pulleys. (or I could make a hole, it all depends on what you guys wanna use.)
Eventually Iāll release all CAD files in a .step format. But not until I test this stuff.
Goodnight All!
PS: ditching the bearing seal in the interest of reducing cost.

The screws that are keeping the belt cover in place are also holding the motor to the mount?
no, there is a separate set of 4 underneath the cover.

For all who have been following this thread and whoāve already read it, Iāve updated the original post with the final design.
Hopefully thereās enough demand for 10 or so sets? (20 sides total)
Thatād be a relatively good start just to get them out there and tested.

Iād love to get in on the first run of these. Need something for 50xx motors to help replace these deathtrap mounts. Weāre do i sign up? Whatās your time frame look like for first batch?
I have a pair of Calibers and 107s for my commuter build and I like the way your pulley cover hugs close to the wheel in the sketch and doesnāt leave room for things to fly into the belt. I plan on running a single 6374 with an 8mm shaft for weight savings so this mount looks like it would work perfectly so far.
Sounds like a great build! Hopefully Iāll have the first batch out soon enough.

Hereās for those who actually plan on getting one, so I can estimate how big of an initial lot is needed.
- Single Motor
- Dual Motor
- I voted before but donāt think Iāll be buying it

Itās for US people only right?
Depends. Iām in the market for affordable (not cheap but not $$$)mounts for 50xx motors on caliber trucks. I like the look of these, but looks like thereās only a few of us looking for anything atmā¦
I was interested in some inexpensive mounts too, but then DIY had labor day sale and I snagged a pair of reverse for $90. I wish I could buy them for a max of $20 per piece.
Seems like it, although Iām sure demand will increase once Iāve got pictures of an actual set on trucks working.

If you need a tester, I daily my board to work 7 days a week.
What do you think a small batch run would cost?

a price range would be good. i know depends on how many order but a starting point would be nice.
