Do you have any video of them in action?
Thanks. No videos of mine yet, but it's basically a clone of Stielz hub motors except its not sensored.

In terms of gravel/rocks/detritus getting inside the motor, would it be possible to add a small screen to the vented side?
I do plan to put enclosures on them, that's why I left the screw holes in the back of the motor, in case I need to use it. Also designing this enclosure to hold and house E0designs hall sensors.

or did you swap the bearings for bigger ones?
The bearings are 14mm OD and I used two of them for the outer side. The inside uses the big skirt bearing.

Pity the aussie dollar is so crap atm, the 63mm motors are $92 currently, but I have an old pair of paris and a lathe! grrrrr!
So by my calculations running 5s on 90mm wheels will put you at 47km/h or 29mph nominal. Using a max amps of 70, this makes about 1.3kw/motor. This could be a primary issue as to why you are not getting a smooth start - simply not enough power for the gearing you have. I assume a smaller wheel diameter will not leave enough thane to ride on for long?
Yeah, it's very easy to do if you have a lathe and know how to do internal surgery on the motor. I do not advise any wheels smaller than 90mm on these 6374 (5974 actual). I may even use a 97mm since I'm so used to bigger wheels. I would install in on a drop through AND drop down deck though.
With the Skyrc ESC I'm using, its very smooth after the push off. It has an option to really widen the coasting/neutral range, so the big wheels just roll for a long time. Still would prefer it sensored though, will also try out the VESC.
