Garmin Varia RTL510 and saddlebags

I'm looking at the Varia RTL510, and like the features, but am wondering what the Garmin engineers were thinking when they designed the mounting system for it? Nearly every cyclist I know rides with a saddlebag, and there is no mounting option provided with the unit, especially for those of us whose seatpost doesn't poke up above the downtube about a foot or more... I have found a 3D printed bracket from a 3rd party, that clips onto the strap provided on most saddlebags, but it appears like it might not be the most stable mounting option...

I have a similar problem with my Garmin Varia radar. This is exacerbated by having short legs, so my seat post doesn't have much exposed length to it.

On one bike, I got a real small saddle bag and crammed it under the saddle.

On another bike, I bolted a Garmin flat mount to a rear luggage rack, which works fine if you don't mind having the damn rack on all of the time. (I don't, because I often use it, but lots of roadies wouldn't want to to that).

I purchased a 3D printed saddle mount and it's pretty secure on there.

I've fitted a Garmin Varia rear light (not the RTL510 though) to a rear rack on my Electra Townie cruiser using a couple of parts. This may help someone who already has a rear rack with reflector mount holes and wants to fit a Garmin Varia rear light onto the rack instead of the seatpost. It uses one of the reflector mount holes on a rear rack.

First I ordered a K-Edge Gravity Top Cap Mount that usually replaces your headset top cap:

I also needed an M6 self-locking nut (and a washer for it):

Here's all the bits shown together with the K-Edge headset cap disassembled:



Attach the cap to the reflector mount on the rack using the bolt supplied with the cap and the self-locking nut:



Refit the Garmin mount insert into the cap:



Here's how it looks:





And here's the rack mounted on the bike showing the Garmin Varia rear light:

Nicely done, and well-photographed...

Not too sure, though, that I could do anything similar to my Pinarello GAN road bike... no fenders, you know ;-).

Yes it's that one. It also has a slot through the mount so I zip tied it to the saddle.

I should know, I designed that mount. Glad you decided to use the zip tie, when I ask most people they don't even know there is a slot for one.

Cateye did replaced their old clip with a new one which can also attached with zip tie.
