平衡（balance）是各個動作或姿勢中，能夠維持穩定狀態之能力。日常生活中，從走路到從事各種不同複雜性的運動，如跑、跳、溜冰、踢足球等等，平衡一直是基本動作能力分類裡的一個重要層面。De Oreo ＆ Keoch在1980年時，將平衡分成四種：
Balance is each action or postures, can maintain stable state of ability.  In daily life, from walk to engage in various kinds the complexity of sports, such as running, jumping, ice skating, football etc, balance has been basic action ability is an important aspect of the classification.  Balance into four kinds by De Oreo & Keoch at 1980:

	姿勢平衡(postural balance)，指身體保持與地球上重力平衡關係的能力，一個人要維持平衡，支撐點必須在重心線上，否則，不是跌倒就是必須要有立即的補救動作。 First, postural balance, mine is with earth body keep refers to the ability of gravity balance relationship, a person must be maintain the balance point in focus mine part, otherwise, not fall down or must be have remedial movement at once.
	靜態平衡(static balance)，即身體不動時，維持身體某種姿勢一段時間的能力，如站立、單足站立、倒立、站在平衡木上維持不動，或（雙手）倒立動作，皆屬靜態平衡。 Second, static balance , that’s body motionless, maintain physical some pose for a period of time, such as the ability to stand up, stand up single foot, handstand, stand in the balance beam to remain unchanged, or (hands) handstand action, are those all of static balance.
	動態平衡(dynamic balance) ，指身體在空間移動時，維持控制身體姿勢的能力，動作中重心會不斷地改變，是移動性及操作性動作的主要因素。如彈簧床、特技、溜冰與游泳等都需要這種平衡能力。 Third, dynamic balance, the body dynamic moving in space, ability of the maintain control body posture, movement the center of gravity will continue to change, main factors of the mobility and operation action. Such as spring bed, stunt, skating and swimming etc. all need this balance ability.
	技巧平衡(skilled balance) ，如體操運動員所表現出來的技巧性絕技及結合複雜動作之平衡能力。(Hastad & Lacy’ textbook, p. 203) Fourth, skills balance, such as the gymnasts to shown balance ability by the complicated movements and combining stunt technical. (Hastad & Lacy 'textbook, p. 203)

在日常生活中，年幼時，學習坐著，可能是人生首先碰到的平衡之考驗。然後是由地上爬行，四腳著地掙扎地站起來之考驗，頭重腳輕、經常跌跤，又是另一次的考驗，在一週歲開始才能擺脫「無法抗拒地心引力」的窘境。中年時期，除非神經系統出現障礙，人類比較沒有平衡的困擾。等到生命末期，又面臨控制平衡與抗拒地心引力的關鍵時刻，老年跌跤可能帶來嚴重的後遺症。
In daily life, when our young, learn to sat, Could be the first came across the balanced life test. Then the test is craw on the ground and with four feet to struggle to stand up, top-heavy and alway’s fall, is another test, began to get rid of "can't resist gravity" dilemma at one year old. Middle age, unless the nervous system appear obstacles, human less balance problems. Until the end of life, will faced with resist gravity balance control the key moment, old age could be brings the serious sequelae .

源自於德國，這款沒有踏板的小型二輪車，目的是讓幼兒在交互用兩隻腳踢著自行車走的同時，也訓練身體的平衡感。
From Germany, this small two-wheeled vehicle without the pedal. The purpose is to allow the children to interact with two feet kicked the bike to go at the same time, Also training the body's sense of balance.
