Kamen Rider Build transforms by inserting two Fullbottles into the Build Driver's Building Modules ( ビルディングモジュール, Birudingu Mojūru) and plugging them into the Twin Fullbottle Slots ( ツインフルボトルスロット, Tsuin Furubotoru Surotto).

This is due to their Hazard Level increasing/decreasing depending on emotions. The stronger the emotions, the stronger the Rider's attacks will be.

L&P Amplifier ( L＆Pアンプリファー, L&P Anpurifā): A converter installed inside the Driver that converts emotions into energy.

It reads Hazard Levels, and will prevent transformation to anyone lower that a Hazard Level 3.

Qualifizer ( クオリファイザー, Kuorifaizā): A biometric scanning device located in the black section at the rear of the Adjust Bind.

When the Driver is not in use, it is stored inside the Driver.

Adjust Bind ( アジャストバインド, Ajasuto Baindo): The yellow strap used to fix the Build Driver upon the waist.

It is so strong that it can withstand Smash attacks. It utilises high-strength material with heat and impact resistance, allowing it to protect internal mechanisms.

Safety Guard Case ( セーフティガードケース, Sēfuti Gādo Kēsu): The outer parts.

During transformation, it develops the Snap Ride Builder ( スナップライドビルダー, Sunappu Raido Birudā) (or any other type of 'Builders'), a compression device resembling plastic model runners, allowing transformation to occur.

Building Modules ( ビルディングモジュール, Birudingu Mojūru): An expansion device built into the Twin Fullbottle Slots.

It takes in the Transgel Solid ingredients inside of the Fullbottles and feeds it to the Building Modules.

Twin Fullbottle Slots ( ツインフルボトルスロット, Tsuin Furubotoru Surotto): The slots that Fullbottles are inserted into.

The faster the crank is spun, the more energy is developed.

Vortex Lever ( ボルテックレバー, Borutekku Rebā): The crank used to activate and operate the Build Driver.

By turning the Vortex Lever, the Vortex Charger spins, activating the internal Nitro Dynamo ( ニトロダイナモ, Nitoro Dainamo) engine, generating enough energy to transform and deal deathblows.

Vortex Charger ( ボルテックチャージャー, Borutekku Chājā): The circular energy generator unit.

The Build Driver is composed of the following parts:

Ī Hazard Level of 3 is required to be able to transform using the Build Driver, otherwise the anti-theft security measures on the Driver will activate and electrify the user to unconsciousness.

The Build Driver is the first and foremost system developed as part of Project Build, using Fullbottles as its primary collectible device.
