Antitheft Device for 1Up Bike Racks on Rivian Crossbars

[marbro67]

I'm a big fan of the 1Up bike racks and have had one for several years. With the purchase of the R1T and the Rivian Crossbars, I had to switch from the traditional 1Up mounts to what they refer to as "flush mount". I've added some pictures for reference.

This new flush mount however has a security flaw. The hex bolt that secures the rack to the cross bars is easily accessible to anyone with the right sized Allen wrench. It would be fairly easy to unbolt the rack with or without a bike on it.

I can't take credit for the idea because I got from a buddy but I thought it was such an elegant solution that I had to share. I purchased a small bag of 5mm solid plastic ball bearings. Had to order a 100 even though I only needed 4. I then took the plastic bearing and tapped them into the hex bolt. The bearing are just a little larger than the hex and with a slight tap of a hammer, they are nice and snug.

So how does this prevent theft, you might ask? Well, it simply prevents an Allen wrench from fitting into the whole. Can't get the wrench in the whole, can't unscrew the bolt, can't steal the rack or the bike.

If I ever have to remove the rack from crossbars, I can simply pry them out with a pick or drill through them with a small drill bit. Plus, I've go 96 more available!

Rack solutions aside (well done there), love those bikes! Wouldn't worry about the rack as much as that beauty of a Ripmo.

2 questions for you: What size are the bikes? How do you make sure your front wheel holder on each rack isn't going to contact the spoiler /lip?

 

[marbro67]

The RIPMO is a 29” wheel and the gravel bike is a 27.5. To prevent the tire rubbing the spoiler, I used a sharpie to mark the rail so I know how far to lift the front part of the rack. So far so good.

Can you explain more about the "flush mount"? The only thing I see on their web site is bike racks that are hitch-mounted. Are these flush mounts made by 1Up and can you buy them individually? thx

25¢ solution to your ball bearing blockage.

Your move, Marc.

 

[COdogman]

The ball bearings are a great and cheap solution. Not knowing what size that bolt is, I was going to ask if you could replace it with a security style like these:

Off-Topic: Just want to chime in to say the 21's are looking good, even with the aero insert! They don't get enough love.

yes they make flush mount. It’s listed under roof racks and then when you select the rack, there is an option for flush mount.

Check out the roof racks here: Roof Rack – 1UP USA | OFFICIAL SITE (1up-usa.com)

The "flush mount" mounts to the crossbar t-slot rather than using a bracket, so it's just a tidier install.

A cool thing about the 1UP USA racks is you can buy another part to convert the roof racks to a hitch mount if you want (and incrementally add more rack units). Very cool modular system. 2’’ Single-Hitch Assembly Slotted – 1UP USA | OFFICIAL SITE (1up-usa.com)

The ball bearings are a great and cheap solution. Not knowing what size that bolt is, I was going to ask if you could replace it with a security style like these:

I wanted to replace with tamper-resist, security bolts. I asked 1UP the size of the bolts used. They are 5/16-18 x 3/4" long. These are the correct size and in stainless steel. The replacement bolts and tool are less than $30 shipped.

It worked like a charm. See pic for fix. I replaced all four bolts.

 

[TLDR_71]

@Greg any chance Mcmaster sells the T-slot end to pair with it?

 

[Greg]

I am not with my rack right now, but here is a stainless steel T-slot nut that fits the 5/16" - 18 screw. See if the width and height of the 'T' would fit inside the Rivian rack.

FWIW, you can order the T-slots from 1up for $5 each.

1. Click on the following link: Additional Payment.
2. Change the price ($) pointed out below from $1 to $<total cost of units x $5>.
3. Do not change the "quantity."
4. Click add to cart.
5. Include in the order notes at check out “(X8) flush mount whispbar nuts (SKU: 250001) ”

I We had the 1Up racks and they are great. Then I found the QuikR Mach 1 rack for our heavier e-bikes. Similar design, but tool less and heavier duty. Super happy with them. We use it on both our Rivian R1S and Tesla. Check them out here.
