bxm 街式小轮车选购

极限运动时下风靡全球,而在极限小轮车的领域之中,其种类也是五花八门,就像是所有运动竞赛一般,越到深入专精的时候,所使用的器材更是分别越细。特别是讲究技巧技术的极限小轮车,玩得专精的玩家们甚至于会为了一些招式而将车上的配件作改装。今天的这一课就先教入门基础的分辨最普遍的两种车型,以避免在选购时买到四不像的车款,而花了冤枉钱。
车型一:(STREET)街式车,在极限运动之中街式项目又分为PARK、U形板(半管)、街道、JUMPING。
车型二:(FLATLAND)平花车,以平地花式为主,也就是一般所称的FreeStyle。
火箭筒:
一般称之为火箭筒的辅助器,街式车多采用钢质以承受如滑竿之类的高强度动作。
平花车的火箭筒是提供车手额外踩踏的空间,因此多采用铝质。
齿盘、曲柄:
街式车所使用的齿数稍大,以用于在短距离需要加速度的动作,曲柄的长度也略长一些。
平花车的加速机会少,齿数小而曲柄也较短,防止一些动作碰脚。
车把(龙头):
车把的选用上,街式车会使用略宽的车把,把手也略曲。平花车的车把则多为直(零角度)。
前叉:
街式车的飞跃动作居多,前叉片需要前移的,以增长轮距提供稳定及吸震,
平花车讲究灵活与操控,前叉片基本无移,前花鼓位于车架头管角度的切线正下方。
座包:
强调吸震的街式车,座垫面积大而软,但仍然是常常损坏的零件之一。
平花车的座垫则属于把手作用,十分多动作需要提着座垫。
外胎、钢丝:
街式车所使用的外胎较为一般,图中的外胎是仿效机车形式,街式车使用的胎压较低,但又必须防止落地撞击所产生的蛇咬破胎。
平花车的外胎是整圈都具有纹路,主要提供花式表演时,与地面或鞋底增加摩擦,其胎压可达140PSI以上,而极限小轮车目前均使用48(36)根钢丝较为普遍。
后花鼓:
街式车使用的花鼓注重耐用,不用考虑后滑行倒退时的影响。
平花车的后花鼓颇有学问,内附离合器,在倒退滑行时,曲柄不会跟着倒转。
护具:
具速度及冲击的街式车项目,在护具方面则增加了护膝、护肘、手套、安全帽,安全帽还可依项目不同而选择其型式。
平花车所使用的护具也如同freestyle一般随性。踏板是最具杀伤力的零件,保护小腿的护具是极限单车最基本的装备之一。
刹车:
具前后刹车的街式车,其走线方式配合旋转器,可以于空中作多样把手旋转的花式;平花车一般不装后刹车(甚至于无需刹车)所以无需旋转器。前后刹车均以悬吊式为主,刹车感觉较顺畅的悬吊式刹车在极限小轮车中仍是主流,V式刹车由于灵敏度过高反而不适合。后刹车的位置多半是藏于下叉,以避免造成防碍。
极限小轮车多少钱才买得到?差异点又如何?
极限小轮车制作的考量重点在于强度,因此并不像一般单车以轻量来评车。小小的一台极限小轮车其重量超过15公斤是很正常的,而材质的选用上,街式车仍以钢质为佳,平花车则逐渐采用铝合金。因此,材质与强度稳定性则反映到价格面上,入门级车约在台币一万元以下(RMB:2000),一万五至两万(RMB5000-8000)的车款已经可以让你又飞又跳。车型粗犷、耍起来酷炫、刺激度惊人,加上各地的极限场地纷纷建立,比起其它型式的单车而言,极限小轮车算是便宜又大碗的新兴运动,这也是其快速窜红的原因之一吧!


BMX小轮车的选购

BMX经过二,三十年的发展,从单一的竞速BMX发展出自由花式BMX(BMX FreeStyle),也就是从原来BMX起源的 泥地竞速(BMX RACING) 到现在平地花式(FLATLAND)街式(STREET)VERT(U型池)土地腾越(DIRT)等多个项目。下面介绍以下BMX自由花式车的选购。 也称火箭炮是BMX特有的东东之一,在其他自行车上一般是见不到了。火箭筒属于BMX的一种辅助器,一般安置在BMX前后车轮的两侧,也就是车轴上。街式车的火箭筒一般为钢质材料所制(现在也有钛质的)主要是用来做街式动作中滑杠, 呲台等动作,较注重结实耐磨程度,相对平花车的要细些,表面较为平整无太多花纹。平花车的火箭筒主要是为车手用手握用脚踩等提供更多的抓点和支点从而做出更多动作所用,因此表面花纹较粗糙目的是更好的抓握和增大脚踩时的摩擦力,使之不易滑落,现在许多厂商也采用表面用滑板沙纸或胶圈等设计做火箭筒也是出于此目的。平花火箭筒材质一般采用铝质。 (Sprockets,Cranks)在牙盘的选用上,街式车与平花车相比所使用的牙盘通常齿数稍大,以用于在短距离需要加速度的动作,曲柄的长度也略长一些,通常是选用175MM以上长度规格的。而平花车使用的牙盘齿数较少,多用不多于28齿的牙盘,因为小牙盘配相应的飞轮,蹬起来很轻,在练一些平衡动作时容易使上劲,并且平花加速机会少。曲柄也要短一些一般使用165MM长度规格的,使做起动作来更加方便。 (Handlebars):车把的选用上,耐用结实是平花与街式车选车把的两个最基本的要求。无缝钢管所做出来的车把绝对是必须的,街式车多爱选用U型车把(2-PC BARS),由于只用到两根钢管焊点只有两处因此最为结实牢固。平花车的车把多为多根钢管焊接而成,目的是车把处有更大的空间来完成动作。平花车喜欢用小角度的车把,也有用到0度的,目的是为车手做转车把动作时正反把的感觉更接近,更有利做动作。 (Forks)街式车的飞跃动作居多,前叉片需要前移的,以增长轮距提供稳定及吸震平花车讲究灵活与操控,因此前叉基本上是小角度和零角度的,使前花鼓位于车架头管角度的切线正下方,这样做同样也是为了前轮做转车把动作时正,反把的感觉更接近。 (Seats)强调吸震的街式车,座垫面积大而软,但仍然是常常损坏最厉害的零件之一。平花车的座垫则属于把手作用,车身上主要的抓点之一,因此座包要小巧方便手的扶握。 (Tires)由于街式和平地花式的车胎均属自由花式BMX的车胎所以区别较小,可通用,车胎的表面较平滑,花纹较浅,车胎打气时气压一般在100PSI。主要是为车轮在练习时滚动的时间更长且更加稳定。街车和平花车相比,花纹更密,以更为增加在道具地面的摩擦力。而平地花式车的花纹比街式车的还要少相对更简单,主要特点是更适合增加车手的鞋与车胎的摩擦,而且车胎滑行更加平稳。 (车轴):(Hubs)两种车均采用10MM和14MM两种BMX专用规格的车轴,在后轴上区别较大街式车使用的花鼓注重结实耐用,轴棍一般常用14MM规格的,比较粗,因为街式,做动作受力比较大,用粗轴棍的目的也就是为了结实。平花车的后花鼓则颇有学问,其后花鼓里内附离合器,在倒退滑行时,曲柄不会跟着倒转,目的是方便做动作时曲柄能固定住不动。这也就是所说的平地花式理合轴! (Brake Levers ,Brakes)街式车车手大多只装后刹车,其走线方式配合旋转器,可以于自由旋转车把,不受闸线的制约平花车一般根据车手的习惯安装。可以不装后刹车只装前刹车,可以不装前刹车,也可以都不装刹车,或同时装两个制手都用来控制前刹车。但刹车感觉顺畅是最为关键的。

Psychologists has used numerous facts to bear out the argument/statement/claim that in order to recover speedily from negative emotion,you should allow yourself to cry.You needn't be ashamed of crying.Anxiety and sorrow can flow out of the body along with tears.Consider the case of Donna.Her son unfortunately died in a car accident.The intensity of the blow made her unable to cry.She said,"It was not until two weeks later that I began to cry.And then I felt a big stone had been lifted from my shoulders.It was the tears that brought me back to earth."
