Isithuthuthu
Xa ixesha lekwindla nobusika liqala ukuwa kwekhephu, uninzi lwabakhweli beebhayisikile baya kuthi cwaka babuyisele iibhayisekile zabo kwigaraji. Ngaba kuya kwahluka ukuba bendikuxelele ukuba ungakhwela a ibhayisekili ngemini yekhephu? Ngethuba nje kukho iivili ezinamafutha, yonke into inokwenzeka.
Ukuchaneka, le ngu ibhasikiyeli eyenzelwe ngokukodwa ukukhwela ikhephu, exhotyiswe ngamathayara aqhelekileyo alwa nescid-wide iibhasiki zombane idayara enobubanzi obumalunga ne-6.35 cm, kwaye amavili atyebileyo anokufikelela kwi-10 ukuya kwi-13 cm. Ukonyuka komphezulu wonxibelelwano phakathi kwamatayara amakhulu kunye nomhlaba kunciphisa uxinzelelo (ndicinga ukuba kufanele ukuba phakathi kwama-34-69 kPa), ukuze umqhubi akhwele kumhlaba othambileyo ofana nesanti, udaka okanye ikhephu ngokuthanda.
Iprototype yebhayisikile enamafutha inokulandelwa emva phaya kwiminyaka yee-1980, xa abantu abathanda ibhayisekile abangcolisa ingca basusa isiphithiphithi sebhayisekile kwintaba esantini nakwikhephu!
Ngo-1986, injineli yaseFransi uJean Naud wakhwela iNtlango yeSahara enamavili akhethekileyo ayenziwe nguMichelin. Phantse ngexesha elinye, ugqatso lwe-Iditabike, olwalubanjwe kwangoko emva komdyarho owaziwayo we-Iditabike e-Alaska, lwavusa umdla omkhulu wabakhweli beebhayisikile, kwaye abantu abanomdla balungisa izixhobo zabo ukuze baziqhelanise neemfuno zokukhwela ikhephu.
Kwangelo xesha, abakhweli beebhayisikile zeendunduma eNew Mexico, e-USA baqala ukuvelisa iibhayisikile zekhephu ezixhotyiswe ngamavili amakhulu ubukhulu kwaye behamba yonke indlela eya eAlaska ngeminyaka yoo-1990. Ngo-2005, inqwelo yesikhululo egama linguPugsley eveliswe yinkampani ebizwa ngokuba yiSurly Bikes eMinnesota yabekwa ngokusemthethweni kwintengiso. Le yayiyimoto yokuqala enamafutha avelisiweyo. Umyili wayo uDave Grey ucacisile malunga nokuyilwa kwale moto ngolu hlobo: “Imodeli efanelekileyo kukhuphiswano, ukuhlola zasendle, ukuhamba ngebhayisikile entabeni, imveliso yezolimo okanye imveliso, ukuzingela / ukuloba / ukutya ukutya, ukuhamba ngombane ngebhayisikile Zonke iibhayisekile ezijikelezayo, ukuhamba , ukukhwela ibhayisikile entabeni / inkampu. ”
Ke ngoko, ngengqondo engqongqo, imoto enamavili enqatha ayisiyonto intsha; kodwa kuyinyani ukuba khange iphinde iqondwe de ibuyele emehlweni abantu ngamandla kule minyaka idlulileyo. I-Associated Press inike ingxelo yokuba amavili atyebileyo “lelona candelo linokubakho kushishino lweebhayisekile”; Iphephancwadi i-Outdoor liyibize ngokuba “yeyona ndlela ishushu kwezokuhamba ngebhayisikile” kwaye yayithelekisa “neenqwelo eziqhutywa ngabantu”
Kubakhweli beebhayisikile, eyona nto inomtsalane kukuba banokuqhubeka nokukhwela ebusika. Nokuba bafuna ukukhwela esixekweni ngokuthanda, okanye baye kwikhephu okanye endle ukuze bonwabele amava amnandi ngakumbi, amavili amanqatha anokuhlangabezana nemfuno. Ayisiyiyo loo nto kuphela, lo mdlalo mtsha utsala umdla wabakhweli beebhayisikile abanomdla, abanjengabathandi bemidlalo yokutyibiliza ekhephini, abaya kufumana ibhayisekile ngumdlalo wobusika opholileyo nonandiphekayo.
Kwixesha elidlulileyo, kwakungekho lula ukufumana ibhayisekile yombane enamavili atyebileyo. Zimbalwa iivenkile ezithengisa iimveliso ezinjalo, kwaye zimbalwa izitokhwe (kwiimeko ezininzi inye kuphela okanye zimbini). Ngoku, ungathenga itayitile enamanqatha iibhasiki zombane kwisaphulelo kwiwebhusayithi esemthethweni ye-hotebike. Ukuba awunawo amavili ibhayisekile yombane oyithandayo, unokuzama Isithuthuthu Ekuqaleni
Kwixesha elidlulileyo, izigcawu ezinjalo bezingathelekelelwa kubahambi ngebhayisikile: ukukhwela kwikhephu, ukugqitha kumahlathi angenampopoma; okanye ukukhwela ibhayisikile ekwehleni kumhlaba ozele imiqobo, ujikeleze phakathi kwamahlathi aluhlaza. Kubonakala ngathi kuphela ngabahambi ngebhayisikile baseNordic abanakho ukulawula ezi ndawo. Kodwa kule mihla, ukukhwela itayara elinamafutha elinobubanzi obuphantse bube yi-13 cm kunokuhamba ngokulula kwikhephu. Nantsi into esiyenzayo, oku kukhwela ikhephu, kushushu kakhulu!
Ngenxa yokubonakala kwamanqatha, amavili enqatha ahlala egxile ekuqwalaselweni. Amavili amanqatha ahlala etsala umdla wabantu abadlulayo. Xa ukhwele kwisihlwele unxibe iisuti ezinzima zekhephu kunye neebhutsi zekhephu, inqanaba lokudumisa liphezulu kakhulu. Emva kwayo yonke loo nto, wonke umntu unesimo sengqondo sokuba ibhayisekile ngumdlalo onokwenziwa kuphela kwimozulu eshushu.
KwiGrand Targhee Ski Resort e-Wyoming, ukuhamba ngebhayisikile kwikhephu kuye kwaba ngumdlalo othandwayo. Indawo yokuphumla yakhele umgaqo webhayisekile ecaleni kweendlela ezine zekhephu ngokukodwa kubathandi beebhayisikile bekhephu. Le ndlela yebhayisekile igcwele isimbo seNordic ziikhilomitha ezili-15 ubude.
Umfana omde kwaye obhityileyo wavela ekhululekile xa wayeqhuba ibhayisekile elingana nombane ngesithuthuthu esinamavili atyebileyo. Nangona ndandikhefuzela kwaye ndibila kakhulu, ndandisondele kwi-10 yeemitha emva kwakhe. Ukubetha kwentliziyo yam kwakukhawuleze kangangokuba intliziyo yam encinci yayiza kutsalwa. waqhuma. Nokuba izixhobo azikhaphukhaphu, ukukhwela ibhayisekile ekukhuphukeni kwikhephu kusengumsebenzi womzimba, singasathethi ke ke ukuba ubunzima beli bhayisekile abukhanyi. Ukunxiba iimpahla ezininzi zasebusika, ukunxiba isigcina-ntloko kunye neebhutsi ezinzima zekhephu, kunye nobhaka, ubunzima bonke bonyuke nge-45 kg. Obu bunzima benza ukuba lo msebenzi ungabi lula kwaphela.
Umkhenkce nekhephu kubude obuziimitha ezingama-2377 kuphazamise ukuphefumla kwam esele kunzima. UWilliam waphindaphinda wema ngobubele walinda ukuba ndilandele ukuze andincede ndibuyele kwisingqi esiqhelekileyo sokuphefumla. Ukubona umkhweli emncinci kunam, ekhefuzela kwaye esokola ukukhwela edlula kuthi, ukuzithemba kwam kwakungcono kancinci.
Le nkcazo ingentla yendlela enzima yokunyuka kunokuba nzima ukuphumelela abantu abathanda ukukhwela ikhephu. Olona lonwabo lukhulu lokuhamba ngebhayisikile ibisoloko luyolo lwenkululeko xa usihla intaba-ukumelana ngokukhululekileyo nokujika okubukhali, kwaye ungqonga unyuka usihla.
Ukubonelela ngokutsalwa okwaneleyo ukuqinisekisa amava amnandi okukhwela, amavili awazukugcwala kakhulu-malunga ne-35 ukuya kwi-103 kPa. Khawufane ucinge imvakalelo yokuhlala esihlalweni sebhola, esifana kakhulu nemvakalelo yokuhlala kwitayara elityebileyo. Ngokuchaseneyo, xa ukhwele ibhayisekile yendlela, amavili amxinwa azisa uxinzelelo oluphezulu (758 kPa), kwaye ukungcangcazela okuvezwa ngumkhweli kwibhayisikile kuya komelela ngokufanayo.
U-Anderson ugxininisile kwisikhokelo sokuba kufuneka uzame ukulandela iziko lendlela xa ukhwele. Ukhumbuze ukuba ikhephu kumacala omabini endlela lithambile kwaye ibhayisekile kulula ukubambeka. Emva kwexesha, uAnderson ngokobuqu wabonisa iimeko eziyingozi ezinokuthi zenzeke xa ujika ngokukhawuleza okanye uye kude kakhulu.
Uthe xa ekhupha ikhephu ezindlebeni zakhe, wagigitheka wathi, "Ngethamsanqa ibiyindawo ebithambile." Wenza umbono oqinisekileyo kum ekhephu-umkhweli weengelosi zekhephu.
KuAnderson, amavili amanqatha amnika enye indlela yokungena ehlathini ebusika. Ukuba ukuhamba ngebhayisikile kuyaqhubeka nokukhula kancinci, umkhweli unokuya kwelinye icala. Njengokuba abakhweli beenqwelo moya bejonge ezantsi kubantu abathanda ikhephu ekuqaleni, abo bathanda ukukhwela ihashe nabo baya kujongana nemibuzo kunye nemiceli mngeni yokugibela ikhephu ngokwesiko. Nangona kunjalo, ukuba aba bathandi besi ski banethuba lokuva ngebhayisikile yekhephu, abo bakhwela iimoto zekhephu okanye bonwabele umkhenkce kunye nekhephu ngoncedo lwesileyi baya kufumana ulonwabo olungapheliyo lweebhayisikile. Okwangoku, bakwimeko yokulindela ukubona kwaye babone.
