Glossary Of Scooter Terms
Last Updated: 01/21/2013
Deck - The Base of the scooter in which all parts attach to.
Headtube – Attached to the base, its purpose is to hold the headset bars and fork.
Headset - Is the set of components on a scooter that provides a rotatable interface between the fork and the head tube. The two types headsets are threaded and threadless.
Fork - Component that is inserted into the headset and used to mount the bars and also the front wheel.
Threaded Fork– Term referring to a type of fork or headset in which a large diameter nut threads on the top tube of fork compressing the headset components to enable proper rotation of the fork in the headset.
Threadless Fork- Term referring to a type of fork or headset in which a compression system (ICS, HIC) is need to compress the headset components to enable proper rotation of the fork in the headset.
Starnut – A flanged spring steel nut that seats in the fork or bars allowing the connection of a compression system.
HIC - Hidden Internal Compression. a shim that is slipped over the top of the fork, a bolt is inserted into the top of the shim, the bolt threads into the starnut contained inside the top tube of the fork, the bolt is tightened to compress the headset components allowing fork rotation.
ICS - Inverted Compression System. Uses a 200mm bolt insetered into the base of the fork tube, the bolt then threads into a starnut contained in the base of a standard diameter bar (1 ¼’) enabling proper rotation of the headset components.
SCS – Standard Compression System. A one piece bar clamp and compression system, an elongated clamp is slipped over the top tube of the fork, a top cap and bolt is then inserted into the top of the clamp, the bolt threads into the starnut contained inside the top tube of the fork, allowing fork rotation.
Bars – Chromoly tubes in various lengths and widths welded together to create a stylish control device used for steering, spinning and lifting the scooter.
Oversized Bar – Common name for a bar with a 1 ⅜” down tube, the cross bar is ⅞”.
Standard Bar – Common name for a bar with a 1 ¼’ down tube, the cross bar is ⅞”.
Clamp – Available in standard and oversize, used on the base of the bars after installing onto the fork the clamp uses bolts to pinch the bars and put pressure on the fork, allowing proper steering control.
Grips – Various shaped rubber material applied onto the end of the cross bar to provide style, control while reducing vibration and hand fatigue.
Bar Wrap – A printed or colored sticky back vinyl product,that is cut and applied to bars allowing a custom look for the scooter.
Wheel - A core surrounded by urethane, common sizes are 100mm and 110mm diameter; durometer ranges from A30 (soft) to D100 (hard), rebound is also important, more rebound carries more energy and is faster but you lose traction.
Wheel Bearings - Two bearings that are pressed into the wheels core, one on each side with a spacer in between, the spacer prevents the bearings from being pushed into the wheel core upsetting the proper alignment of the bearings and axle.
ABEC - There are five classes from largest to smallest tolerances: 1, 3, 5, 7, and 9, the higher the number the greater the speed capabilities, The ABEC rating does not specify other critical factors, such as smoothness, ball precision or quality/type of steel used. most common are the abec 5
Brake – A foot controlled device bolted to the back of the deck used to control and stop the scooter.
Brake Spring - A small spring installed with a spring type brake that allows the brake to return to its operating position after application.
Axle - Machined hardware used to install the rear wheel into the deck and the front wheel into the fork.
Pegs – Attached to the fork and rear of the deck with longer axles, used to grind and stall on various objects.
Deck Spacers - Installed on each side of the rear wheel, deck spacers are designed to center the rear wheel in the deck.
Grip Tape - An abrasive material with an adhesive on the back designed to be installed on the top surface of the deck to give a rider maximum foot control.
Complete – Fully built and fully assembled scooter.
Graphics – Design’s that make the scooter stand out.
Wheelbase – Distance in between the front and rear wheels.
Hardware – Miscellaneous pieces used to fasten or affix the scooter.
