ibhayisikili
Lapho kuqala ikhephu lasekwindla kanye nobusika, iningi lamabhayisekili lizobuyisela buthule amabhayisekili abo egalaji. Bekungehluka yini uma ngikutshela ukuthi ungagibela a ibhayisikili ngosuku oluneqhwa? Inqobo nje uma kunamathayi asenamafutha, konke kungenzeka.
Ukucacisa, lokhu kuyinto ibhayisikili kagesi yakhelwe ngokukhethekile ukugibela iqhwa, ifakwe ngamathayi amaningi obubanzi obubanzi be-skid-ezejwayelekile amabhayisikili kagesi abe nobubanzi besondo okungaba ngu-6.35 cm, kanti amathayi omzimba angafika ku-10 kuye ku-13 cm. Ukwanda kwendawo yokuxhumana phakathi kwamathayi amakhulu naphansi kunciphisa ingcindezi (ngicabanga ukuthi kufanele kube phakathi kwama-34-69 kPa), ngakho-ke umshayeli angagibela emhlabathini othambile onjengesihlabathi, udaka noma iqhwa ngokuthanda.
Uhlobo lwesithuthuthu olunamafutha lungaqala ukubuyela emuva ngawo-1980s, lapho abahamba ngebhayisekili bezimpande beqala ukushuba isikebhe sezintaba esihlabathini naseqhweni!
Ngo-1986, unjiniyela waseFrance uJean Naud wadabula iSahara Desert ngamathayi akhethekile abekelwa uMichelin. Cishe ngaso leso sikhathi, umjaho wama-Iditabike, owabanjwa ngokushesha ngemuva komjaho odumile wase-Iditabike e-Alaska, wavusa umdlandla wenqwaba yabantu abahamba ngamabhayisekili, futhi abashisekeli bashintsha imishini yabo ukuze ivumelane nezidingo zokugibela iqhwa.
Ngasikhathi sinye, abagibeli bamabhayisikili endunduma eNew Mexico, eU.SA baqala ukukhiqiza amabhayisikili eqhwa anamasondo amakhulu ubukhulu futhi agibela yonke indlela eya e-Alaska ngawo-1990. Ngo-2005, inqola yesiteshi ebizwa ngePugsley ekhiqizwa yinkampani ebizwa ngeSurly Bikes eMinnesota yabekwa ngokusemthethweni emakethe. Le bekuyimoto yokuqala yamathaya ekhiqizwa ngobuningi. Umklami wayo uDave Gray uchaze kabanzi ngomqondo wokuklanywa kwale moto kanjena: “Imodeli elungele ukuncintisana, ukuhlola zasendle, ukuhamba ngebhayisikili ezintabeni, ukukhiqizwa kwezolimo noma izimboni, ukuzingela / ukudoba / ukudla okokuthenga ukudla, ukuhamba ngemoto kagesi Amabhayisikili ajikelezayo wokuhamba ngebhayisikili, ukuhamba , ukuhamba ngebhayisikili entabeni / ukukanisa. ”
Ngakho-ke, ngomqondo oqinile, imoto yamathaya anonile akuyona into entsha; kodwa kuyiqiniso ukuthi akukaze kuphawulwe kabusha kuze kube yilapho ibuyele emehlweni abantu ngokuqinile kule minyaka edlule. I-Associated Press ibike ukuthi amathayi amafutha "yiyona ingxenye yezimakethe engaba khona kakhulu embonini yamabhayisikili"; Umagazini i-Outdoor uyibize ngokuthi “umkhuba oshisa kakhulu ngokuhamba ngebhayisikili” futhi wayifanisa “nezimoto zasendle eziqhutshwa ngabantu”
Kubahamba ngamabhayisekili, ukuheha okukhulu ukuthi ekugcineni bangaqhubeka nokugibela ebusika. Noma ngabe bafuna ukugibela edolobheni ngentando, noma baye eqhweni noma endle ukuze bajabulele okuhlangenwe nakho okujabulisa kakhulu, amathayi asemafutheni angahlangabezana nesidingo. Ngaphandle nje kwalokho, lo mdlalo omusha ubuye ukhange abanye abahamba ngamabhayisekili abanelukuluku, njengalabo abathanda ukushushuluza, abazothola ukuhamba ngamabhayisekili ngumsebenzi wokuphumula nobumnandi obumnandi kakhulu ebusika.
Esikhathini esedlule, bekungekho lula ukuthola ibhayisekili kagesi enamathayi omningi. Kunezitolo ezimbalwa kuphela ezithengisa imikhiqizo enjalo, futhi kunezitoko ezimbalwa kakhulu (ezimweni eziningi kukodwa noma okubili). Manje, ungathenga isondo lamafutha amabhayisikili kagesi ngesaphulelo kuwebhusayithi esemthethweni ye-hotebike. Uma ungenalo ibhayisikili likagesi lamathaya owathandayo, ungahle uzame ibhayisikili kuqala
Esikhathini esedlule, lezo zimo zazingacabangi kwabakhwele ngamabhayisekili: ukugibela iqhwa, ukudlula emahlathini angenalutho; noma ukugibela ibhayisekili ekwehleni komhlaba eligcwele izithiyo, elivalekile phakathi kwezinkuni ezivulekile. Kubukeka sengathi yilabo kuphela abahamba ngamabhayisekili eNordic abakwazi ukulawula lezi zindawo. Kepha kulezi zinsuku, ukugibela ithayi elinamafutha elingamasentimitha acishe abe ngu-13 cm kungahamba kalula eqhweni. Lokhu yilokhu esikwenzayo, lokhu ukugibela iqhwa, ukushisa okukhulu!
Ngenxa yokubonakala kwamafutha, amathayi omafuta bekulokhu kugxilwe kuwo. Amathayi omzimba ahlala edonsela ukunaka kwabadlulayo. Lapho ugibela esixukwini sigqoke amasudi asindayo e-ski kanye namabhuthi eqhwa, izinga lokudumisa liphezulu kakhulu. Ngemuva kwakho konke, wonke umuntu une-stereotype ethi ukuhamba ngebhayisikile ngumdlalo ongenziwa kuphela esimweni sezulu esifudumele.
EGrand Targhee Ski Resort eWyoming, ukuhamba ngebhayisekili sekuwumdlalo othandwayo. I-resort yakhele indlela yebhayisekili eduze kwemizila emine yokushushuluza abathanda kakhulu ukuhamba ngeqhwa. Le ndlela yebhayisekili egcwele isitayela seNordic ingamakhilomitha ayi-15 ubude.
Insizwa ende futhi emfishane yabonakala ivuselelekile lapho igibela ibhayisekili kagesi elinosayizi omningi ngamathayi wamafutha. Noma ngangiphuphuma futhi ngijuluka kakhulu, ngangisengamamitha ayi-10 emva kwakhe. Ukushaya kwenhliziyo yami kwakushesha kangangokuba inhliziyo yami encane yayisizodonswa. kuqhume. Noma imishini ilula, ukugibela ibhayisekili eweni eweni kusewumsebenzi omkhulu kakhulu, singasasho ukuthi isisindo saleli bike asilula. Ukugqoka izingqimba eziningana zezingubo zasebusika, ugqoke isigqoko ski kanye namabhuthi eqhwa asindayo, kanye nesikhwama sangemuva, isisindo sonke sikhuphuke ngo-45 kg. Lesi isisindo senza lo msebenzi ungabi lula nakancane.
Iqhwa neqhwa endaweni ephakeme ngamamitha angama-2377 kuphazamise ukuphefumula kwami okunesisindo. UWilliam wama kaningi ngomusa futhi elinda ukuba ngilandele ukuze angisize ngiqale kabusha isigqi sami sokuphefumula esijwayelekile. Ukubona umgibeli emncane kunami, ethambekele futhi elwa kanzima ukuba adlule ngathi, ukuzithemba kwami kwazizwa kuncono.
Ukuchazwa okungenhla komgwaqo onzima wokukhuphuka kungaba nzima ukuwina abathanda abasha ukugibela iqhwa. Ubumnandi obukhulu kakhulu bokuhamba ngamabhayisekili bekulokhu kuyinkululeko yenkululeko lapho wehla intaba-ubhekana ngokukhululekile nezikhathi eziguqukayo, futhi ushaya phezulu naphansi.
Ukuze unikeze ukuthambisa okwanele ukuqinisekisa isipiliyoni esimnandi sokugibela, amathayi ngeke agcwele kakhulu — cishe ama-35 kuye kwangama-103 kPa. Cabanga umuzwa wokuhlala esihlalweni sebhola, esifana kakhulu nomuzwa wokuhlala uthayela onamafutha. Ngokuphambene nalokho, lapho ugibela ibhayisekili lomgwaqo, amathayi amancanyana aletha ingcindezi ephezulu (758 kPa), futhi ukudlidliza okuzwakala ngumgibeli ku-bike kuzoqina ngokuqinile.
U-Anderson ukugcizelele esiqondisweni ukuthi kufanele uzame ukulandela umugqa womgwaqo lapho ugibela. Ukhumbuze ukuthi iqhwa ezinhlangothini zombili zomgwaqo lithambile futhi kulula ukubhajwa. Kamuva, u-Anderson wazibonakalisa ngokwakhe izimo eziyingozi ezingenzeka lapho ejika kakhulu noma ehamba kakhulu.
Ngenkathi ekhipha iqhwa ezindlebeni zakhe, wagigitheka wathi, “Ngenhlanhla bekuwukuhlala phansi okuthambile.” Wangihlaba umxhwele kakhulu eqhweni — umgibeli wezingelosi zeqhwa.
Ku-Anderson, amathayi anamafutha amnikeza enye indlela yokuya ehlathini ebusika. Uma ukuhamba ngamabhayisekili kuqhubeka nokuthuthuka kwalo okuhamba kancane, umgibeli angahle aye kwelinye ihaba. Njengoba abasiki bengqondo bebheka phansi abathanda kakhulu eqhweni ekuqaleni, abathanda abagibeli bamahhashi bayobhekana nemibuzo nezinselelo zokugibela iqhwa. Kodwa-ke, uma laba bantu abathanda ukushibilika e-ski benethuba lokuthola ukuhamba ngebhayisekili, labo abagibela izimoto ezihamba ngeqhwa noma bathokozele iqhwa neqhwa ngosizo lwe-sleds bazothola injabulo engenamkhawulo yamabhayisekili. Njengamanje, basesimweni sokulinda ngabomvu ukubona.
IHotebike iyathengiswa amabhayisikili kagesi kagesi, uma unentshisekelo, sicela uchofoze ibhayisikili iwebhusayithi esemthethweni okufanele uyibuke
