Using High-Torque Servos (MG996R) for DIY Locking Pins or Accessories?

[Daniel DSouza]

Hi everyone,

I’m looking into some "smart" security mods for my current build and wanted to get your thoughts on mechanical execution.

Has anyone here experimented with using high-torque metal gear servos (specifically something like (Check this -) MG996R) for automated components? I’m considering using one to drive a heavy-duty locking pin for the rear wheel or perhaps a remote-actuated kickstand.

My main concerns are:

Weatherproofing: How are you guys shielding small servos from road spray and grime?

Vibration: These servos have great holding torque, but I'm curious if the constant vibration of a mid-drive or hub motor eventually strips the internal gears.

I've used these extensively in robotics for high-stress joints, but an e-bike is a much harsher environment. If anyone has photos of a similar "active" mechanical mod in their bike garage, I’d love to see how you mounted it!

Cheers.

I use the Pitlock system on one of my analog bikes (skewers, seatpost, saddle, stem, and headlight) and it does give me some peace of mind leaving it locked up for an hour or so. I don't think I would consider complicated servos for automated kickstands or locking pins. Just more things to break.

There are a couple of threads on electronic derailleurs on the forum right now if you are interested in that. Some of these derailleurs can integrate with the Bosch Smart System for automatic shifting. You set a preferred cadence and it shifts the gears for you. I don't know how well that works though.
