Felt + flow gets me the company blog , not a bike model so IDK which you got.

As as I Gather your situation, from above.. To fit a basket,
You need to Lose the suspension fork..

alternatives are not going to be a Buy and plug in with a few nuts and bolts..

Tubus has a High Mount Pannier rack , that attaches to the fork crown with a brace
up to the top of the headset/fork steerer

Paul's Flatbed tried a Prototype Porteur rack that mounted to the top of the fork
stanchion tubes , but it never went into production.. small though their production is..

So I'd say unless you go to a rigid fork you have to go to a custom fabricator; frame/rack Builder.
