WHAT'S IN THE PACK

The HYDRA E9 PETROL pack swaps the mid-drive for a 190 cc four-stroke single. The pack includes drawings for the stainless header — bend radii, flange prints and clearance envelopes — plus the intake and airbox geometry we settled on after testing. Everything else matches the electric pack: full CAD, 49 drawings, a priced BOM and a 144-page build manual.

CAD package

Full parametric assembly plus every individual part, exported to STEP, IGES, DXF and native SolidWorks. Engine bay modelled around off-the-shelf donor engines.

Fabrication drawings

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

Bill of materials — 162 lines

Editable spreadsheet with quantities, materials, engine and drivetrain part numbers, live price columns and a running budget total.

How-to-build manual — 144 pages

Step-by-step photo build order: jig setup, weld sequence, engine mounting, chain alignment, fuel and throttle routing, torque table and carb jetting sheet.

55–70 h
