Proto TDI Chopper NEX 84° – Raw

The new 2025 Generation of TDI NEX now features sleek rounded front corners to match the new SCS V3 profile. Also, additionally reinforced I-Beam structure, totally flush bearing bores and new engravings!

The “Chopper” NEX come in 3 headtube angles 83°, 84° and 85°. The Chopper 83° geometry is a direct substitute for the Orion Standard V2 (2012) and the Orion Integrated V1 (2015). The Chopper 84° is the direct substitute for the Orion TH (2019). The Chopper 85° is the first 85° neck ever produced in scootering and has no substitute.

All Models feature engravings of the Model Name, Headtube Angle, Patent Number, USA and PROTO logo and hand stamped with their model-specific production number at time of final QC inspection and packaging.

All TDI NEX are manufactured in house in the PROTO Factory in San Diego, California to the highest precision CNC machining tolerances in the freestyle scooter industry with unmatched attention to detail.

THE TDI STORY

Tunglok Deck Integration (TDI) began in the early 2000s as a way to dial “Two-Piece” folding scooters by securing the Neck and Deck with bolts. This allowed riders to adjust the “Headtube Angle” and “Deck Rise”.

In 2007, I developed the first welded “One-Piece” Deck,” the SR Deck, eliminating bolts but limiting adjustability. When early PROTOtypes failed, I reimagined the Two-Piece Deck, integrating a tongue & groove interlock – “Tung-Loc” – inspired by my grandfather’s cabinetry patent. My patented system distributes impacts away from the TDI bolts, matching the rigidity of a welded deck while offering full customization.

Any Headtube Angle. Any Deck Rise. Any Deck Width. Any Deck Length. Fully interchangeable.

The TDI System brings scooter design full circle – back to two pieces, the way they were meant to be.

This is TDI. This is the Standard Deck System. Enjoy the ride!
