E-Bike Conversion Kit A retrofit kit that turns an ordinary bicycle into an e-bike: a hub-motor wheel replaces the original wheel, a controller switches battery current into the motor phases, and pedal sensors gate the assist to meet 250 W / 25 km/h pedelec rules. 133 parts · 7 subsystems

Electronic Shifting Groupset An integrated drivetrain with motor-driven derailleurs, wireless shifters, and a central battery delivering indexed gear changes at the press of a button. 69 parts · 8 subsystems

Fat Bike An off-road bicycle built around 4-5 inch tires run at 0.2-0.8 bar, whose enormous contact patch floats over snow and sand; the frame, fork, rims, and drivetrain are all widened to clear the rubber. 49 parts · 7 subsystems

Folding Bike A compact folding commuter bike with 16-20 inch wheels, a frame hinge, and a folding stem for transit and storage. 115 parts · 10 subsystems

GPS Bike Computer A handlebar-mounted navigation and training instrument that fuses multi-constellation GNSS positioning with ANT+/Bluetooth sensor data (heart rate, power, cadence) and records the ride to flash memory. 40 parts · 8 subsystems

Gravel Bike A drop-bar bicycle built for mixed pavement and unpaved roads: a carbon or alloy frame with clearance for 40-50 mm tubeless tires, hydraulic disc brakes, and a wide-range 1x or 2x drivetrain. 54 parts · 8 subsystems

Handcycle A three-wheeled recumbent cycle powered by hand cranks: the seated pilot steers with a handlebar while pedalling with both arms, with mechanical chains and derailleurs steering all motion through a rear-axle gearbox. 74 parts · 7 subsystems
