Bottle cage mount holder - Metabikes recumbent

This is a bottle cage mount holder for both chainstays, on a Metabikes Metaphrastic recumbent.

My recumbent is a rear disc brake type, so I don't need the threaded holes on each chainstay to mount a caliper brake.

However, one of the threaded hole (the left one) is used to clip the rear hydraulic hose.

Each mount holder is mounted with a bolt (on the upper side) and with a zip tie (on the lower side). The zip tie is inserted in a little tunnel created inside the holder body (See the plane cut for details)

To hold the bottle cage on the lower side, a 8mm nut is needed, and a short bolt (about 10mm long, bolt head not included).

Finally, I fastened the rear hydraulic hose with 2 zip ties on the left mount holder.
