WHAT'S IN THE PACK

The HYDRA E9 pack is the one to buy if the electronics are what worry you. Alongside the full CAD set and fabrication drawings, it includes a colour wiring schematic, connector pinouts, fuse and cable-gauge tables, and the exact controller parameters we run — printed as a table you can type straight into the software. The battery box is drawn as a bolt-in module so you can scale capacity without touching the frame.

CAD package

Full parametric assembly plus every individual part, exported to STEP, IGES, DXF and native SolidWorks. Opens in Fusion 360, SolidWorks, Onshape, FreeCAD and Inventor.

Fabrication drawings

Dimensioned 2D prints for every tube, bracket and plate — cut lengths, notch angles, hole tables, weld callouts and tolerances. Print-ready PDF and DXF for laser or plasma.

Bill of materials — 168 lines

Editable spreadsheet with quantities, materials, sizes, tested supplier part numbers, live price columns and a running budget total. Nothing generic, nothing guessed.

How-to-build manual — 148 pages

Step-by-step photo build order from bare tube to first ride: jig setup, weld sequence, wiring diagram, torque table, brake bleed, controller mapping and setup sheet.
