Glossary of terms

The following terms are frequently used in documentation from NAKTO Bikes.

Term	Definition	Picture
Battery	An energy storage device with components that deliver a specific voltage and current capable of powering an electric motor.
Basket	A basket is a typical container made of a woven material such as wood or plastic. It is usually used to carry, store, or display items, and it may have handles for easy transportation. Baskets can come in all shapes and sizes and are used for a wide range of purposes, including shopping, organizing, and decorating.
Battery fuse	A battery fuse, often referred to as a "battery fuse" or "battery protection fuse," is a safety device used in electrical systems to protect batteries, equipment, and circuits from overcurrent or short circuits. Its primary function is to interrupt the flow of electrical current if the current exceeds a safe level, preventing damage to the battery and associated components and reducing the risk of electrical fires or other hazards.
Battery Lock	A "battery lock" could also refer to a security or protection feature in some electronic devices. In this context, it may be a software or hardware feature that restricts or locks access to certain battery-related settings or functions, such as preventing the removal of the battery or changing power-related configurations.
Battery Pin	These terminals or pins are used to connect the battery to a device or an electrical circuit, allowing the flow of electricity and powering the device. The positive and negative terminals are crucial for proper battery orientation and ensuring that electrical connections are made correctly.
Battery Slide	A slide track that supports the external battery and assists the battery in the e-bike.	No picture
Bottom Bracket	Collective term for the axle-like components that the cranks rotate, transmitting force to the chainring, the chain, and the rest of the drivetrain. Consists of the "bottom bracket shell," the tube that's open at each side of the bike and is located at the conjunction of the downtube, seat tube, and chainstays. The rest of the bottom-bracket assembly (the bottom bracket spindle and bearings, etc., depending on the specific design) passes through the bottom bracket shell and connect to the cranks. See also "bottom braket shell" and "bottom bracket spindle."
Brake Cable	A brake cable is a type of control cable used in various mechanical systems, primarily in the context of bicycles and some motorized vehicles.  Its main purpose is to transmit force from the brake lever or pedal to the braking mechanism, allowing the rider or operator to control the braking action.

Brake Lever	A brake lever is a hand-operated control component typically found on bicycles, motorcycles, scooters, and various types of vehicles with hand-operated brake systems. Its primary function is to allow the operator to apply force to activate the brakes, which, in turn, slows down or stops the vehicle.
Chain	The components inside each brake caliper that make contact with the brake rotor when a brake lever is squeezed, causing friction that slows the bike.
Charger	A device for charging batteries.
Charging Port	A receptacle on the battery to plug in the charger to charge the battery.	No picture
Controller	The "brain" of the ebike. The controller allows electrical components to communicate and controls the motor.
Crank	One of two metal arms that connect each pedal to the chainring/bottom bracket to move the bike forward when pedaling.
Crank Set	One of two metal arms that connect each pedal to the chainring/bottom bracket to move the bike forward when pedaling.
Derailleur-front	A front derailleur is a component of a bicycle's drivetrain system, specifically designed for multi-speed bicycles. Its primary function is to move the chain between different chainrings attached to the bicycle's crankset. This allows the rider to select different gear ratios, enabling them to adapt to varying terrain and riding conditions.
Derailleur-rear	A rear derailleur is a key component of a bicycle's drivetrain system, specifically designed for multi-speed bicycles. Its primary function is to move the bicycle chain between different gears or sprockets on the rear wheel, which allows the rider to select different gear ratios for varying terrain and riding conditions.
Disc Brake	Type of braking system that uses calipers to squeeze brake pads around the sides of a brake rotor to slow the bike
Fender	A semicircle of plastic or metal that, when installed, is positioned over the wheel of a bike and blocks water, mud, and other debris from spraying up from the tires onto a rider and cargo.
Fork	The front portion of the bike frame to which the front wheel is attached.
Frame	The metal tubing that connects all of the bike components and supports the weight of the rider.	No picture
Freewheel	A mechanism that threads onto the hub and allows the gear/sprocket to be propelled when a rider pedals forward, but also allows the rear wheel to continue to rotate when a rider stops pedalling or pedals backward.
Handlebar	A flexible ring or loop that strengthens or protects an opening.	No picture
Handlebar Grip	A part of the handlebar, one on each end, designed for the hand to grip.
Handlebar Stem	The horizontal tube that connects the handlebar to the steering column.	No picture
Headlight	Light on the front of a bike or other vehicle. Used to increase visibility of the bike and also illuminate the path of the vehicle.
Headset	A system inside the headtube of the bike that uses ball bearings to allow the fork steering column and front wheel to rotate and turn.
kickstand	A swiveling metal bar or bars that can be used to prop up a bicycle when it is not in use.
LCD Display	On some bikes from Rad Power Bikes, the LCD display is a device, located on the handlebar, that shows information including speed, watt output, pedal assist level, and odometer. LCD stands for "liquid crystal display."
Pedal	The component that a rider presses their feet against and rotates to propel the bike.
Pedal Assist Sensor	The component that a rider presses their feet against and rotates to propel the bike.
Rear Cushion	A matching mat for the back hanger of an electric bicycle. Only for Elegance and Pony e-bike.
Rear Rack	A bicycle rack located at the back of the bicycle, above the rear wheel. Used for supporting cargo and, in some cases, passengers.
Reflector	A component that light bounces off of and back to the source of light. Used on bikes to increase the bike's visibility, must be attached and visible at all times, and may be required by law.
Seat	The bike component designed for the rider to sit on.
Seat Post	The long metal tube that connects to the seat and slides into the seat tube.
Spoke	One of many metal rods that connect the rim to the hub of a bike wheel.
Throttle	A feature that allows the rider to manually call up power from the motor and battery without pedaling. Controlled by a device on the handlebar.
Tire	The round rubber/fiber casing for the inner tube that connects to the rim and that the wheels roll on.	No picture
Washer	Flat, circular disk with a hole in the center, placed on a bolt or screw shaft to distribute clamping force of the fastener over a larger surface area.	No picture
