Yes they can. You may have to play around with the angles. There is one angle that I have tried where the motors hit the arch of the hanger. One notch down is perfect.

Are the guides for these drives available. And what locktite should I use for the gear?

For the motor pulley, Loctite 648.

I am unsure if Kevin has made a PDF guide yet, but please consider checking out my video on their assembly, it may help you out a lot. You will need to use green loctite retaining compound for the motor pinion.

Got the drives a couple of days ago and stoked to get them set up. One thing I’m wondering about now is maintenance. What’s worth checking before/after every ride? Maybe just eyeballing exterior case screws? What about “scheduled” checks. Is there anything that should be done at regular intervals? My sense is that the grease lasts a very long time so maybe there’s nothing other than a visual check of the bolts before rides?

if they got wet, try preventing rust maybe. It will be a while until anyone has an issue with these I think.

Yeah I agree hard to say too much yet until theyve got a couple hundred miles on em

Just finished putting together the drive. Sound way more silent than the regular M1 drive and getting the mount to fit was a bit of hassle (requires a bit of filing for the mbs hanger) one thing that bug me tho is that I am using Phatlads hubs and the bolts you get with these don’t seem to go trough the wheel mounts all the way…
I thought these bolts where supposed to be a fixed to the mount and not like this?

Try M4x50mm. Phatladz are wider so they may need longer bolts so they can engage the wheel adapter more effectively

Are those bolts supposed to screw in the adapter or how I have done it now?

They only float. They don’t screw in

Yep, it can look a little weird but if you do the math, they’re well within their strength.

Do we have a video on their sound after they broke in by now?
I just watched the @ShutterShock assembly video (well done by the way).
Just some open questions to those who do have the drives in hand and @Boardnamics for sure.
Between pinion and motor there are no shimms? Means the all the sideway force is pushed on to the circle clip?
Also why no grub screw design on the pinion?
Coming from a broken helical gear because the pinion moved recently I would welcome to see a grub screw as well instead of just a key and loctite.

Thanks! I probably still haven’t broken mine in yet, been too busy with other stuff
Nope, no shims. Yeah, but it’s not actually that much force, well within the capabilities of that.
I asked Kevin too and he said he did it this way because the failure mode on steel-steel gears for a grub screw coming loose is very bad. You’re talking full lockup

The force depends on the helical angle and I can’t say what angle is on the bn drive, but I have seen motor shafts pulling out the bell due to the sideway force on other drives, so I was curious.
If somebody is worried, I think it’s not a big deal to get some 8mm shimms and remove the circle clip thou.
That grub screw argument makes definitely sense.

Ya I was just thinking that too

Looks like you will need M4x55/60mm the default bolts are already M4x50mm.

Thank you very much for the video @ShutterShock !! I also have oilslick Mbs trucks and it does not fit… How did you file your trucks? Do you think there a risk of removing too much material and damage the truck strength? There is no more paint on mine and it still do not fit.

I tried to design an adapter so that I could use these on Flipsky’s 15.2" DKP trucks. Unfortunately, when I put it together I realized that it would only fit 50xx mm motors
