How to correctly torque the rear axle nut (s) on Radrover 5

[Wallycalm]

I need to change out the rear wheel on my new Radrover 5 - short question:   is it safe to hand-tighten the rear axle nut on the motor cable side  to re-assemble the rear wheel after changing a flat, etc? 

More detailed Q:   How do I torque the rear axle nut to the correct nm? there is a cable coming out of the middle of that nut !!    In the Radbikes official video it  shows the owner hand tightening with an open-ended wrench, no Torque wrench.   And the caption below says to torque to 35 or 40 Nm, implying a Torque wrench  should be used - how to do this on the motor cable side?  This can only be reached with a (fancy IMO) clawfoot attachment to a Torque wrench, but that's a bit involved and those are tools that I don't own.

My guess - most owners just hand tighten and go for the feel of 'tight enuf but not too tight'. Is that safe given all the forces on an e-bike?

Thanks in advance,

Bob

It's a good question and I actually had someone ask me something similar about how to tighten the bolt on their Juiced ebike. Juiced specifically sells their own, but again it isn't a torque wrench: https://bit.ly/3dFyTGR

Maybe someone else knows of some tool that might work. I guess this type of open ended torque wrench might work, but gosh that's pricey: https://amzn.to/30zSPFU

Maybe car mechanics have something you could borrow?
