Hamba for dorta: izici eyinhloko ilungelo lokukhetha

Kusukela yaqala ukuba khona, futhi lokhu usuku ngebhayisikili sihlangabezane izinguquko eziningi. Waqale waba ukwakhiwa bakudala, futhi manje kukhona onobuhle ezingeke ngokuthi ngaphandle isimangaliso engineering. Kwaphela isikhathi eside ibhayisikili iyunithi kwaba zinjalo. Futhi saya ezokuthutha ezinjalo kuphela emigwaqeni flat. Kodwa ngo-1970, wasungula libhayisikili entabeni (MTB), kodwa kwavele kwaba yize revolution yangempela velosipedostroenii. On ibhayisikili entabeni, ungakwazi ukuhlola indawo, okuyinto kwaba ngaphambilini iyatholakala Abahamba. Ngokuhamba kwesikhathi, kwakukhona ngebhayisikili eyala abathintekayo mountain ngebhayisikili. Namuhla eziningi udumo yazuza Dirt Jumping Street-Isivivinyo. Ake sizwe ukuthi yini kufanele kube ibhayisikili ukuthi kwakungase ukwenza lezi ezemidlalo.

imiqondo Jikelele

Ukungcola ukweqa ngokwezwi nezwi ehunyushwa ngokuthi njengoba "jumping odakeni." Ngomqondo onabile, inkulumo indlela okuyiyo. Biking kwenziwa ithrekhi ukulungele ngokukhethekile, esakhiwa phansi trampolines. kuyanda meteoric, kokwehla isihawu, izindiza isiyezi - yilokho balindelwe izibukeli enkundleni yokugijima ngoba Ukungcola. Kodwa ngo-mgwaqo ukuze amacebo Isivivinyo azisetshenziswa ezintabeni zobumba nasemadolobheni sezwe izakhi. Bobabili ezemidlalo kudinga ulwazi omuhle ibhayisikili (okubizwa ngokuthi hhayi kuphela ibhayisikili, kodwa ibhayisikili). Uyala zifana ngokuya umthwalo ezokuthutha, kodwa kukhona umehluko othize.

Hamba for Ukungcola Street: izimpawu ezisemqoka

Isetshenziselwa jumping Ushintshe entabeni emabhayisikili BMX. Noma okuthile phakathi kwalezi zinhlobo ezimbili. Ayevame nesisindo eziningi futhi babe kwabhoboka - labaqaphi elingemuva.

Hamba for ukweqa uhlale igiya elilodwa kuphela. Nokho, abakhiqizi abaningi Positioning izindaba multirate efana dertovye noma stritovye. onobuhle ezinjalo kufanele kulolu hlu ongakhetha olucutshungulwayo lapho ukhetha ibhayisikili. Uma ibhayisikili amagiya eziningana, umenzi kungenzeka Ulondoloze ukuze uzimele nezinye izingxenye ezibucayi. Ngaphezu kwalokho, u-shift igiya kuyize ngokuphelele kulezi eyala. It kuphela kwandisa isisindo ezimbili Wheeler nezindleko.

Ukuze uthole saqala kungokuhluke efanelekayo zakhishelwa intengiso ngoba Ukungcola Hamba. onobuhle maKristu abizwa 'komplitami ". A abasubathi abanolwazi kakhudlwana futhi uyabasindisa abanomoya kahle ababeyizazi imininingwane imininingwane yomsebenzi wabo, ukuqoqa izindaba yabo ofanele kakhulu kubo izakhi noma silungisa ikhithi yakho. Ake sixoxe izakhi ebalulekile ibhayisikili wedwa.

Uhlaka

Lena ingxenye ebaluleke kakhulu futhi kuyabiza kwanoma iyiphi ibhayisikili. I izici eziyinhloko ifreyimu - kuyinto geometry yayo nendwangu womshini. It kuncike kuzo izinga uzimele futhi sokufaneleka yayo oluthile lomdlalo.

Ukungcola ibhayisikili okwesikhathi ngqo noma kumele kube amelana imithwalo kakhulu. Ngakho-ke, amandla ifreyimu usendaweni yokuqala. Ngo womshini yabo, izinto ezinjalo ezisetshenziswa:

1. Hi-Ten - high quality steel. It ngokuvamile lisetshenziswa womshini komplitov engabizi. Uzimele wenza kulokhu kwaziswa ine isisindo sibambe ongezansi, kodwa akanawo amandla anele. Ngakho-ke, Tuning we ibhayisikili iqala ke.

2. Alloys aluminium. Uhlaka le nto ukala kancane futhi akusho kakhulu adle. Nokho, ngeke ayicime ngokugcwele ukushaqeka kabi lalungiswa. Ngokuhamba kwesikhathi, nomsebenzi asebenzayo, aluminium aqoqana ukukhathala. Ngokuhamba kwesikhathi ke kuholela ekubhujisweni ifremu. Nokho, phakathi abalandeli jumping on libhayisikili kukhona eziningi abalandeli aluminium ozimele.

3. steel ingxubevange. Ngo ozimele ezinjalo kusetshenziswa-chrome molybdenum Alloys. Umkhiqizo kusukela kule kahle impahla aluyidambisi amandla ezivukayo lapho lihlala futhi ithambisa punches. I ozimele medium ingxubevange steel kuyabiza futhi ngokuvamile sisetshenziswa ekilasini ipayipi nge nonuniform odongeni ukujiya. Lokhu kuvumela ukwandisa amandla futhi ukunciphisa isisindo.

4. Magnesium futhi titanium Alloys, futhi inhlanganisela - esezingeni materials for ozimele. Kodwa ungakwazi ukuyikhokha, njengoba umthetho, ochwepheshe kuphela.

Ngakho, singaphetha ngokuthi emabhayisikili kangcono Ukungcola Street - yalabo abanhliziyo Uhlaka ezenziwe ngensimbi engagqwali. Inikeza isilinganiso elikhulu isisindo namandla. Aluminium futhi has a lot of abalandeli, kodwa kuyinto ekahle eyala lapho kungekho imithwalo super-okusezingeni eliphezulu kanye noma yikuphi ukudweba.

Uhlaka geometry

ukunakekela okukhethekile unikezwa isikhashana ezinjalo, njengoba i-geometry ifremu. Lapha kulapho umehluko oyinhloko kubonakala Ukungcola-ibhayisekili ibhayisikili emgwaqweni. Ngokungafani nezinye, Rostovka akusho inendima ekhethekile. Kuziwa kuqhame ubude tube phezulu.

I-Ukungcola ibhayisikili has a usayizi elikhulu. Ngaphambili unxantathu Uhlaka ngokuvamile has a ubude 570-590 mm. Unxantathu ezingemuva ubuye ngempela eside - 370-410 mm. Ubushelelezi kokwehla ihlinzeka engela ethize ukuthambekela ikholomu ayo - 68-70 degrees. Ngo mgwaqo isivivinyo, lo mklamo singase sinyuse isikhathi indiza, kodwa ngabe benza kube nzima, "wokudonsa out" ibhayisikili. ibhayisikili Street, ngokuphambene has phambili lemfisha (545 mm) futhi bakhulise (345-350mm) onxantathu. A enyakazayo eziqondisa ikholomu lapha 71-74 degrees.

izimpaphe Lower dert-ibhayisikili parallel phansi noma abe engela engakhi kuthambekela. Ngakho, ukuthutha noma ezishaywayo ne oluvala amasondo misa, noma kancane ngezansi. Lo mklamo ikuvumela understate maphakathi yesisindo ibhayisikili, okuyinto kunomphumela omuhle Dynamics ukushesha futhi kwenza indiza uzinze ngokwengeziwe. Ngaphezu kwalokho, ibhayisikili ngoba Ukungcola jumping ngokusebenzisa geometry Uhlaka kangcono zilawulwa ithrekhi cornering ashukumisayo.

I ibhayisikili ukuthutha mgwaqo ephakeme, okwenza kube lula "ukudonsa" ibhayisikili ikhwele ezingemuva oluvala amasondo nezikhonkwane. Ngokweqile ukwandisa ukuphakama ukuthutha akudingekile. Lokhu kuzokwenza libhayisikili engafanele ezindizayo futhi kuzoholela ekulahlekeni ukuzinza. Njengomthetho, emabhayisikili ngoba Ukungcola Street zisebenzisa ukushiya ovundlile ukuthi ahlinzeke ikhono ukushintsha ubude wheelbase.

amasondo

Elinye iphuzu, okuyinto ngokuvamile kuyindaba impikiswano - kukhethwa amasondo. On amabhayisikili ngoba bran futhi iqonde, ngokuvamile beka ububanzi isondo 24 noma 26 amasentimitha. Hamba-24 intshi amasondo kuyinto ezihlukahlukene. Kungase kufaneleke kokubili eyala. By the way, ngezinye izikhathi ku Ukungcola ibhayisikili ukubeka namasondo amabili ahlukene:-26 intshi phambi futhi-24 intshi emuva. Ngokuvamile, i-Durty yokugcina ehlelelwe more. Lezi amasondo zingcono ziphathwe i unezikhinsi futhi ukuthambisa kokwehla.

Ibhayisikili lomgwaqo, ngokuphambene nalokho, kangcono baziphathe nge namasondo angu 24 inch. Ziyakwazi kulula ukwenza amaqhinga, ngoba alula futhi ezincane. Hamba ngemuva namasondo amancane kuyinto compact okuningi. Yena kalula wakhipha futhi kubhekeleke kangcono izimo eziqondisa ukunyakaza.

Ukukhethwa kubuye sincike ububanzi ukukhula umsubathi. Uma ngaphezu 180 cm, ukhululeke ukuthenga ibhayisikili ngenhloso ububanzi isondo 26 amasentimitha. Kodwa uma kuwukuthi ngezansi - 24. Ukungcola ngamathayi wazisebenzisa yimpandla eqinile noma poluslik. Futhi ku-Street - slicks noma poluslik. Hamba for kuzuba kumele babe amasondo nge nezinsimbi double.

ekuphambukeni

Enye incenye lebalulekile ngebhayisikili. ibhayisikili Street, kanye Ukungcola, ngokuvamile ekukhathaza Wabasaqalayo abangenayo izifiso lokugijima endaweni ethile ngesigamu ngonyaka. Ngalesi isikhathi esifushane emalungeni umgibeli ukwazi kulimala uma ipulaki ngokungalungile ekhethiwe.

Lezo zinto ezinhlobo ezimbili: kanzima futhi amortization (short-stroke). ipulaki Soft ukuhambisa kuze kufinyelele 13 cm ngeke ivumelane abalandeli isitayela ngendlela enobudlova indiza isikhathi eside futhi esincike esipara kanye Wabasaqalayo. Kodwa lo mkhiqizo ngempela eqolo. On komplitah Wabasaqalayo ngokuvamile eshibhe ukumiswa ekuphambukeni enomqhele.

On ibhayisikili emgwaqweni, esetshenziselwa kuzuba ongaphakeme, kungcono ufake ngemfoloko ukukhanya eqinile. It kuzokuvumela ukusetshenziswa esiphezulu amplitude yizembe nokulawula kangcono libhayisikili. Enye inzuzo yokuhamba kwesikebhe lokhu isixazululo - a Ukonga okukhulu. Kubalulekile ukuthi i-plug esinjalo esasenziwe of chromium-molybdenum ingxubevange noma hayneta.

imikhiqizo Standard abhekwa ngaphansi 14-20 mm oluvala amasondo. Abasakwazi eqinile futhi ethembekile. Akubalulekile ukuba agqoke ekuphambukeni ibhayisikili ngoba jumping ngaphansi oluvala amasondo 10 mm obukhulu - ngokushesha ehluleka.

Esisezimpondweni kanye stem

Usayizi eziqondisa incike ububanzi emahlombe futhi ngokomzimba ukuqeqeshwa umdlali. isondo Lunga ngokusakazwa 700 mm ukuze nabagibeli enkulu nokuningi. Kodwa umuntu ovamile kuyoba ububanzi ngokwanele ukuba 680 mm.

On emabhayisikili ngemfoloko eqinile nakho ngeke kusize ukukhwezwa hromolevye umkhumbi, futhi uma i-plug uthambile, futhi aluminium efanelekayo. Ukuphakama incike ukunambitheka siqu, kodwa ngokuvamile kunzima ukubeka handlebars ekuphambukeni ephakeme kunaleyo esithambile.

Ukuze igxuma ibhayisikili ekahle stem iDemo nge ubude 35-50 mm. Lesi bike is kahle ephethwe, kusukela izandla abasondelene maphakathi gravity. Ryder indoda enkulu ungafaka stem eside.

amabhuleki

Amabhuleki Uhlobo, isimiso, akubalulekile. Okuqakathekileko, asendleleni ibhayisikili noma cha. Nikotorye abasubathi uhambe zonke okuxekethile, kodwa Wabasaqalayo akukuhle ukusheshe ukususa engeyokuqala. Ngesikhathi esifanele, kungenza ukukuvikela kungadaleka ingozi embi kakhulu. Ukungcola Ibhayisikili lomgwaqo noma kungaba ngisho ifakwe vibreykovymi amabhuleki elula, kodwa kungcono ukusetha disc.

sehhashi

Konke ilula: esihlalweni kufanele kube ububanzi futhi ezithambile. Bottleneck ngeke bakwazi ukunqanda imilenze lapho begxuma. Ingxabano ezinzima kuyinto ngamadolo akhe, ngokuletha ukungakhululeki.

Ukuvikelwa

Ngaphambi kokuba uqale ukuba bahlanganyele Ukushushuluza kakhulu ngesithuthuthu, qiniseka ukuze uthole isivikelo. Isinyathelo sokuqala ukukhetha isigqoko. Ungathatha fullfeys okuthiwa, kodwa isisindo saso singamakhilogremu eziningi, phezulu kakhulu futhi kuvimbela isibuyekezo. Ngakho ukuqala kangcono ukuthenga ithafa isigqoko Bowler.

Okulandelayo, udinga ukuba banakekele emabhulashini lokuvikela kwedolo futhi indololwane amalunga shins. Futhi ungakhohlwa ukuthenga amagilavu.

Amabhayisikili we-Street / Ukungcola: Intengo

Lezi ezemidlalo ziye ziyasatshalalaiswa, okusho ukuthi emakethe has a esikhulu Ukukhetha emabhayisikili, izingxenye kanye izingubo. Intengo amabhayisikili ngoba igxuma ezemidlalo luyehluka kuye ikhwalithi ukumisa imininingwane. Hamba Wabasaqalayo ivela 300 1000 zamadola. Ngokuvamile, njengoba wazi, akunamkhawulo ekupheleleni.

isiphetho

Ukukhetha ibhayisikili (Street noma dert esilindele wakho - akunandaba), uzohlangana eziningi umehluko wemisindo nemiqondo yamagama. Ukuqonda isidingo lokhu noma lokhuya ngokuningiliziwe kuyofika abanolwazi. Kukhona futhi imibuzo Kwase kuyisikhathi eside ngilithanda impikiswano phakathi nabagibeli. Zidlala indima ebalulekile kanye esikuthandayo we umsubathi. Ukuqala ngigibele ibhayisikili futhi emkhathini kakhulu, uzoshesha ukubazi nabo bonke umehluko wemisindo nemiqondo yamagama lo msebenzi othakazelisayo. Futhi ungakhohlwa ukuthi indlela yolwazi kuphela ngokusebenzisa ukuqeqeshwa njalo.
