A training handle for attaching to a bicycle to allow a person to stabilize the bicycle while a new rider is learning to balance. The training handle is adapted to engage the bicycle where the rear wheel engages the rear fork. The training handle includes: at least one engaging portion defining a hole for receiving the axle of the rear wheel; an elongated handle portion extending generally upwardly away from each engaging portion; and a first stabilizer extending inwardly from each engaging portion from a location adjacent the hole for engaging the rear fork and preventing movement of the training handle.
