A motive vehicle comprises a frame, a front wheel, two rear wheels, a seat, a handle, a headset, and a pedal device. A front sprocket is coupled to the pedal device and a rear sprocket is connected to a differential. The motive vehicle is powered by human pedaling. The differential communicates with the rear wheels to allow the vehicle to turn on a zero turn radius. The wheels are attached to the frame with an attachment apparatus that allows for easy detachability. The seat is also detachable and adjustable. Brake cams are attached to the frame, and engage the rear wheels when the bike is pedaled backwards. An alternative embodiment comprises a multiple operator motive vehicle, wherein a rear vehicle with two wheels is coupled to a front vehicle having three wheels. Further, another two-wheeled follower unit may be coupled to the first rear vehicle for a greater number of riders. Additional attachments may also be made.
