P clips on bottom of rack

Hey so i got myself a nice steel bike. However it doesnt have the threaded hole at the bottom next to the rear wheel.

Can I attach the rack using a P clip like you do at the top or do I need a new rack?

Problem is its an ebike with a special rack to hold the battery, so dont want to gave to bodge a different style of rack onto the bike.

Not talking much weight maybe 10 kg at most.

Have used a 'P-clip' on the bottom of the seat stays to attach a rack on a carbon bike without any issues. Should work fine on other materials as well.

P-clips work fine but I always preferred if either the top or bottom two mounting points were onto something more sturdy rather than all 4 mounting points be via p-clips.

depends on which you get and how they are used.. get them and ask for approval when you can show your work.

On my road bike I use P-clips at the bottom, and a Problem Solvers seat post binder with rack mount bosses up top. I would not mount a rack with 4 P-clips, especially not one carrying 10 kg (over 20 pounds!) of weight.

Yes you can but a better solution for both the top and bottom is a Tubus rack adapter (see Item 3 on the page). They are easier to use than P-clips and they are stronger. I've used them for top and bottom mounts on this bike



Here's close up details

p-clips work at the top because the top point bears very little weight, most of the weight goes to the bottom mounting point with the top mounting point just keeping the rack from falling backwards.

I second the suggestion of a tubus rack mounting kit:
Tubus Fit Solutions and Accessories ? TheTouringStore.com

Or, you can buy a rack with something similar already built in like the Axiom Streamliner:
https://www.amazon.com/Axiom-Streaml...HY2/ref=sr_1_2

I know others also make racks specifically for bikes without rack mounts.

In my opinion the best mounts at the top are the seatpost-integrated kind:
https://www.amazon.com/Axiom-Trekk-C...3I6/ref=sr_1_2

Of course at the top lots of things will work, p-clamp work fine to if you have a metal frame.
