儿童自行车尺寸划分

儿童自行车尺寸划分 回到自行车 儿童自行车的大小是如何划分的,我家宝宝应该买多大的车车, 儿童自行车的规格是按车胎的外径划分的，一般是12寸(英寸)、14寸、16寸、18寸、20寸等。其中12、16、20是国际标准，14、18寸国外较多，内销产品中也很常见。 这个尺寸对照表，我真能找出10种版本，国内国外各有各的size，我找到一个相对比较正规的，复制出来 Guide to Kid's Bike Sizes Age Child's Height Bike Wheel Size Age 2 - 5 26 - 34 inches 12 inches Age 4 - 8 34 - 42 inches 16 inches Age 6 - 9 42 - 48 inches 18 inches Age 8 - 12 48 - 56 inches 20 inches Youth 56 - 62 inches 24 inches 给孩子选车，最好是能试骑一下同龄小朋友的车车，(除个别特殊车型外，规格尺寸是通用的)，注意:一定要宝宝骑着合适，不要为了能骑的时间长而买大，车车买大了，可能干脆就骑不了，或者不安全，骑行姿势也不正确。正如你不会给自己37号的脚买40号鞋一样，千万不要给宝宝买他/她骑不了的车，14寸的车车，也不会比12寸的车车宝宝骑的时间更长. 很多家长在选购儿童自行车时，总是希望选购的儿童车能多骑几年，因此从其他妈妈那里获取的信息就包括14寸比12寸能多骑几年的说法，但购买时却发现经常卖家没有14寸的儿童自行车，其实这是一个误区。 r included in the County, with the right of abode overseas natural persons; (2) expand the scope of borrower type of occupation; (3) to apply for a loan for business borrowers, as well as the business unit controller or major shareholders. 2, the maximum loan amount (1) to cancel "a maximum loan amount of RMB 300,000" requirement; (2) both for personal consumption and business purposes, different methods were used to determine the loan amount. 3, the loan terms (1) the loan terms with borrowers and not more than 60 years of age; (2) lending operation, should be based on the borrower's production cycle and the anticipated income situation, scientifically and rationally determine the loan period.

(H) loans to pay: defined the trustee payments and autonomous operational requirements for payment. 14寸和18寸车是非标的，因此生产数量较少。而且14寸车介于12寸和16寸之间，往往是孩子家长错过了给孩子买12寸车的最佳时间，孩子个头已经不小了，但骑16寸又差一点，于是就觉得买个14寸的比12寸能多骑几年，实际上14寸车也只能骑2年，在换车的时候又会遇到20寸车差一点，买16寸车又觉得骑的时间短，只好买18寸车的问题。很快又要换20寸车。 因此实际最经济的还是1岁半以后给孩子买第一辆12寸的车，骑两年后再换成16寸的，再骑两年换成20寸的。 试验车尺寸是否合适的让宝宝跨在车架上(不是坐在车座上)，两手握住车把，两脚平行站立，宝宝胯下离车架的上管应还有2公分以上的距离。 如果车架是没有上管的，可以让宝宝用胳膊肘放在车座的中央，看手指伸开后能否够到把立管。 如何判断车的好坏 选购儿童自行车时，家长往往看着花花绿绿的，完全凭自己的喜好来挑选。但实际上，选购儿童自行车，最重要的是从宝宝使用的角度去评判。好的儿童自行车的标准是什么呢, 1、安全，有碍安全的功能和设计，即使漂亮，也应该慎重选择。比如，车上有零件尖锐或突出，(按照欧美的规定，螺丝等突出的长度不能超过其直径)。要检查焊接是否牢固(焊缝是否均匀整齐)，试骑合适的儿童自行车，车座和车把的安全控制线不能露出来，应插入座管和前管内。护轮安装的定位垫片的突出部分应卡入后叉缺口中，前轴固定前叉的定位垫片的突脚也要卡入前叉腿的定位孔中。否则骑行过程中，会造成严重事故。12寸车的刹车不是特别重要，因为往往这个阶段大多数孩子还不会使用，骑行时有护轮，速度不快，多有家长陪伴。16寸以上的自行车，必须全面检查刹车的制动性能，标准和检查成人车的一样。 2、骑行是否轻快，这一点，家长没有去试骑，但可以有一些简单的判断方法。比如，可以询问售货员，车的中轴是采用金属轴承的还是塑料件，车的前管安装前叉的部分采用的是否是塑料件(可轻易识别)，车子的轮圈采用的是钢圈、充气的还是塑料发泡的。判断标准比较简r included in the County, with the right of abode overseas natural persons; (2) expand the scope of borrower type of occupation; (3) to apply for a loan for business borrowers, as well as the business unit controller or major shareholders. 2, the maximum loan amount (1) to cancel "a maximum loan amount of RMB 300,000" requirement; (2) both for personal consumption and business purposes, different methods were used to determine the loan amount. 3, the loan terms (1) the loan terms with borrowers and not more than 60 years of age; (2) lending operation, should be based on the borrower's production cycle and the anticipated income situation, scientifically and rationally determine the loan period. (E) loans: the three rejected. (F) receive and investigate: 1, defines the principles and requirements of pre-loan investigation, focusing on investigating first source of repayment, and a double investigation. 2, the provision of customer information: (1) "available on request" information, customer reference case where the account manager deciding whether to request; (2) proof of income can refer to the approach in annex format or other format to meet the Bank's requirements; (3) loan operation shall provide the information management unit; (4) copy of the account manager shall verify the information and sign it to confirm. 3, provided for a borrower, guarantor and main contents of units operated by pre-loan investigation. 4, loans for business and apply for amounts in excess of 500,000 yuan, account managers should refer to the measurement limit estimates demand for working capital loans. (G) loans: the loan origination process, provides lenders responsible for review. (H) loans to pay: defined the trustee payments and autonomous operational requirements for payment. 单，那就是，采用塑料件的，传动效果都会比金属件差，骑行和转向不灵活轻快。建议购买金属轴承的。 3、塑料件的材质是否过关，可以通过观察颜色和手感判断。颜色鲜艳光亮，透明感强，手感温润的材质好。塑料件如果用回料色泽不光亮均匀，而且在冬季气温低时，很容易碎裂。夏天长时间日晒，也会很快老化褪色，发脆开裂。 4、附件合理，现在的儿童自行车，往往装备齐全，前后泥板，工具箱，车篮等等。实际上，现在孩子大多是独生子女，在雨天和泥地中骑行的可能性几乎为零，泥板如果有锐利边缘或突起，反而还有安全隐患，实属一个多余部件。而工具箱对孩子上下车是一个阻碍，把小男孩都练得只会从前面掏腿上下车，其实也不是一个符合孩子骑行的部件。车篮倒是外出是可以装些东西，可它会使车把方向变沉(骑车买过菜的都知道)，如果放些水瓶之类可以来回滚的东西，还会影响转向。另外小宝宝哪次外出，都有人当保镖，车篮放东西的概率有多高呢。因此这些附件，大多是从家长审美的角度大加赞赏，非它不可，而实际对骑车的宝宝，则多是负担。这可能也就是欧美的儿童自行车绝无此类附件的原因吧。因此一般12寸和16寸的自行车建议不要安装过多附件，其实只是家长好看，孩子骑起来实际是费劲。20寸的车，孩子比较大了，也有力量和r included in the County, with the right of abode overseas natural persons; (2) expand the scope of borrower type of occupation; (3) to apply for a loan for business borrowers, as well as the business unit controller or major shareholders. 2, the maximum loan amount (1) to cancel "a maximum loan amount of RMB 300,000" requirement; (2) both for personal consumption and business purposes, different methods were used to determine the loan amount. 3, the loan terms (1) the loan terms with borrowers and not more than 60 years of age; (2) lending operation, should be based on the borrower's production cycle and the anticipated income situation, scientifically and rationally determine the loan period.

(H) loans to pay: defined the trustee payments and autonomous operational requirements for payment. 技巧控制车子，独立外出的机会也多一些，应考虑配备后衣架和前车蓝，配备前后泥板，不再需要辅助轮，而应该配备脚撑。 5、外胎要花纹清晰，内胎要好，否则家长就有了一个锻炼身体的好方法，每次宝宝要骑车，你就开始锻炼身体，给车子打气。最后每办法还要去修车那里换内胎。 总之一点，买车是给小宝宝骑的，你选车时要蹲下身子，从他的角度去考虑买一辆漂亮而且安全实用的儿童自行车。 我找了两个“反面教材”，看了你可能会说“呀～我家车就这样啊～”，没别的的意思，其实轩轩的第一台车也是这样的，一台车不骑一辈子，下次购买的时候可以借鉴 这台车可以说在外型颜色装饰上都很吸引我，如果没仔细研究我肯定毫不犹豫的买它，可是仔细就发现问题了。 两个后视镜，一个两三岁的孩子如何能懂得用后视镜，但是有了它孩子就不能避免的朝里看，不看路看镜子那后果是什么。 前车筐，后工具箱外加直梁 r included in the County, with the right of abode overseas natural persons; (2) expand the scope of borrower type of occupation; (3) to apply for a loan for business borrowers, as well as the business unit controller or major shareholders. 2, the maximum loan amount (1) to cancel "a maximum loan amount of RMB 300,000" requirement; (2) both for personal consumption and business purposes, different methods were used to determine the loan amount. 3, the loan terms (1) the loan terms with borrowers and not more than 60 years of age; (2) lending operation, should be based on the borrower's production cycle and the anticipated income situation, scientifically and rationally determine the loan period.

(G) loans: the loan origination process, provides lenders responsible for review. (H) loans to pay: defined the trustee payments and autonomous operational requirements for payment. (3) 是否中轴或后轴上得过紧,可先用手转动后轮，看是否转动顺畅，如果不顺畅应是后轴太紧，可用扳手将后轴的最外侧的紧固螺丝先拧松，然后把内侧的限位螺母略拧出一些，再转动后轮，测试一下，否则再松一点，直到转动轻快，然后上紧紧固螺丝。如果中轴过紧需要在左侧脚蹬处使用大号活动扳手顺时针方向放松螺母，再用一字改锥顺时针放松里层螺母直到脚蹬转动灵活为止。 (4) 是否是有包装物影响车轮转动，拆除所有包装物，再测试。 儿童学骑自行车事项之佩戴头盔 孩子们骑自行车是一个快乐的事，但千万不能忽略了安全。给孩子佩戴安全头盔，是保证安全的重要手段，负责人的爸爸妈妈可千万不能马虎，国外很多国家都立法要求骑车人佩戴头盔，这样会极大降低意外造成的伤害。购买头盔要考虑的两个问题，一是坚固，能真正起到防护作用(市面上几元钱的头盔的作用可以说是聊胜于无，不用也罢)，二是大小合适，不合适的头盔关键时候很难起到应有的保护作用。 有了合适的头盔，要让它发挥100的作用，还要正确佩戴好。介绍一下欧美的眼耳口头盔佩戴法: 首先，把头盔平整紧贴的戴在头上，如果头盔滑向一侧，应加厚头盔内垫或选择小号的头盔。 其次是头部各个部位: 1、眼:当孩子带好头盔时，他从眉毛上方应恰好看到头盔的帽檐。 2、耳:头盔两边的束带应恰好在耳朵下面交叉，形成一个Y字。 3、口:束带卡牢后应能塞进一个指头，使呼吸保持顺畅，但要足够紧，当孩子张大嘴时，应能感受到头顶被向下拉。除了头盔以外，孩子的衣着也应该能够适合安全的骑行: 不要穿过于松的衣服，女孩子最好不要穿裙子骑车，应该穿比较紧腿的裤子，以免衣裤缠绕进传动机构。 孩子骑车最好不穿有鞋带的鞋，有鞋带的鞋带一定要系好。孩子的衣服上应没有吊带或其他容易夹到车子部件里的装饰物。对于新骑手，最好带上手套和护膝护肘。 r included in the County, with the right of abode overseas natural persons; (2) expand the scope of borrower type of occupation; (3) to apply for a loan for business borrowers, as well as the business unit controller or major shareholders. 2, the maximum loan amount (1) to cancel "a maximum loan amount of RMB 300,000" requirement; (2) both for personal consumption and business purposes, different methods were used to determine the loan amount. 3, the loan terms (1) the loan terms with borrowers and not more than 60 years of age; (2) lending operation, should be based on the borrower's production cycle and the anticipated income situation, scientifically and rationally determine the loan period.
