Patent number: 9259777Abstract: A bicycle is provided having a unitary steering tube-crown member and a unitary crank arm-spindle member. A multistage aluminum 3D forging process is used to form the unitary members. This may allow the fabrication of components with substantially hollow interior areas to reduce weight, reduce part count while maintaining high strength and ductility. The multistage 3D forging process provided also allows the combination of multiple components into a single unitary part.Type: GrantFiled: March 8, 2010Date of Patent: February 16, 2016Assignee: CYCLING SPORTS GROUP, INC.Inventors: Christopher P. Dodman, Stephen B. Metz

Patent number: 8469381Abstract: A bicycle is provided having a frame with a seat tube and a bottom bracket coupled to one end of the seat tube. A pedal crank shaft is operably coupled to the bottom bracket. A motor is coupled to the bottom bracket and operably coupled to the pedal crank shaft. A battery is removably coupled to the frame and electrically coupled to the motor. A seat having a seat post is removably coupled to the seat tube, wherein the battery is disposed to remain coupled to the frame when the seat post is removed. In another embodiment, a sleeve is positioned with in the seat tube and the seat post is slidingly disposed in the sleeve. In another embodiment, the bicycle includes a clamp having a plurality of clamp pads that engage the seat post to hold the seat in the desired position.Type: GrantFiled: August 25, 2011Date of Patent: June 25, 2013Assignee: Cycling Sports Group, Inc.Inventors: Christopher P. Dodman, Erik Preston Eagleman, Zachary David Krapfl

Publication number: 20090056496Abstract: A crank assembly formed as a unitary composite structure, the crank arms and crank shaft being hollow to provide maximum weight reduction, the crank arms being over-sized to provide the necessary stiffness and strength. The unitary composite crank assembly may further include a crank claw integrally formed with the crank assembly. Additionally, a spider may be integrally formed with the crank assembly reducing the amount of parts for the assembly, increasing stiffness and reducing overall weight.Type: ApplicationFiled: September 4, 2007Publication date: March 5, 2009Inventors: Christopher P.
