Rostovka Bicycle: Uludwe. Rostovka isakhelo ibhayisekili

Parameter ibalulekileyo, nto leyo eyenza ingqondo ukujonga xa ukhetha isithuthi - yi Bikes Rostovka (oko kukuthi ubungakanani isakhelo). Akukho kubaluleke kangaka eziphathekayo, imodeli imbonakalo, njengoko intuthuzelo ubukhulu efanelekileyo wehashe yentsimbi. Kuphela kulo mzekelo kuya kuba lula ukuhamba.

imbali rostovok

Ukukhetha eyiyo ubukhulu ibhayisekile, kufuneka ithathele ingqalelo inani yemida. Ngaphambili, kwaba lula kakhulu. Kumaxesha Soviet, safumana kuphela Bikes imidyarho kunye indlela. Isakhelo waba geometry umgangatho kwaye umbhobho eliphezulu usoloko zibekwe tyaba. Ngoko ke, khetha ukuphakama eliphezulu kwaba lula. Ukuba kuyimfuneko, ungasoloko ukunyenyisa ngakumbi indawo ivili lokuqhuba kunye isihlalo. Ukhetho isekelwe umbhobho tyaba, t. To. Yaba kuphela ukhetho ayikwazanga alungiswe. Ngamanye amazwi, wasebenzisa Rostovka kuphela isakhelo ibhayisekile njengoko parameter ibalulekileyo. Zonke ezinye hlengiswe apha ekukhuleni.

Okwangoku, uluhlu kuye kwandisa ibhayisekile. izakhelo Kukho of geometry ezahlukeneyo, abaninzi iintlobo ngebhayisekile isihlalo ityhubhu amalungiselelo kwikonw ngekona. Amaxesha amaninzi ukujongana ngezidumbu isondo non-adjustable njalo njalo .. Konke oku nzima ukukhetha imodeli efanelekileyo. Kwaye ngaphandle, abavelisi benkqubo ukuphakama ezahlukeneyo kwaye cinga ngokusebenzisa ubude ezahlukeneyo nkqubo. Ngoku isetyenziswa kuphela isakhelo ibhayisekile Rostovka, kodwa kwakhona ubungakanani kweevili, umgama phakathi ivili lokuqhuba kunye isihlalo, kunye nezinye iparameters. Noko ke, ukuphakama ityhubhu isihlalo isekhona enye yezinto eziphambili. Ukuba yesi eliphezulu kakhulu ukusuka ibhayisekile arhabaxa le nasemiphakathweni, yaye kumbangele ukuzenzakalisa. Kwi ephantsi kakhulu skating isakhelo uba zingemnandanga, kufuneka aphakamise iinyawo zakhe ngaphezu kwentloko yakhe, ngenxa yokuba umthwalo isasazwa ngokuchanekileyo, apho naye yingozi kwimpilo.

Isimboli for ifomula

yokubala Ifomula esetyenzisiweyo kakhulu krwada. Ngaphandle kwabo kukho neentlobo ezininzi. Bayakwazi zinokwahluka nje kuphela model kukhombisa (entabeni, imidyarho yendlela, ezemidlalo), kodwa ukususela umenzi kumenzi. Nangona kunjalo, lo ifomyula zikwazi ukukhawulelana ibhayisekile ethile, awamiswa ngumntu. Kanti kwiivenkile ngokufuthi babhenela kanye indlela abaliweyo ngokukhethwa.

Kwi hlayisekile iindawo zibizwa ngolu hlobo lulandelayo:

• C - ubude ithumbu isihlalo.
• SS - umgama tye phakathi isihlalo kunye ivili lokuqhuba.
• SIZE (CC) (kwiziko namafutha buyo - phakathi ityhubhu ephezulu).
• SIZE * (CT) (kwiziko buyo - umphezulu ityhubhu isihlalo). Le r. N. isakhelo ukuphakama.

Ukusuka umntu kufuna parameter omnye kuphela: ukuphakama perineum - i-HP. Oku kulinganiswa ngaphakathi yonyawo, ukususela isithende ukuya ubudoda. Kwakhona, kwezinye iimeko, ukuphakama lomntu.

Indlela yokubona Rostovka ibhayisekile efanelekileyo: ifomula

Xa indlela yokukhetha kufuneka zicaciswe yokulinganisa ukukhula isakhelo: CC (centre-iziko) okanye CT (iziko-phezulu). Iifomula kulo mzekelo ziya kwahluka.

Rostovka bike indlela ibalwa ngokusebenzisa fomyula ilandelayo:

• SIZE (C-C) = 0.65 x VP.
• SIZE * (C-T) = 0.67 x VP.

Rostovka ntaba ibhayisekile sibalwa ngokwahlukileyo:

• SIZE * (C-T) = 0.67 x VP - 10 cm.
• SIZE (C-C) = 0.67 x VP - 12 cm.

Intaba bike Umgama kakhulu ukusuka ivili lokuqhuba esihlalweni, t. To. Inxalenye yokuqala ngeke usiya khona.

Indlela lwesilinganisi

Ukuze wenze oku, ume endaweni ebanzi, ubambe ityhubhu isihlalo phakathi kwemilenze. Kuyimfuneko ukuba balinganise umgama phakathi nasemiphakathweni kwaye isakhelo. Kuba bike indlela le iparameter elungiselelwe ngamaxabiso ka 25-75 mm, kwaye nangenxa intaba - 100-200 mm, kwezinye iimeko - ku-5 cm.

itheyibhile imbalelwano

Noko ke, asizizo zonke iivenkile babe nethuba ukuzama kwi ibhayisekile. Ngoko ke badla ukubhenela etafileni ezahlukeneyo ahambelanayo. Kuba ezahlukahlukeneyo parameters angumzekelo ezahlukeneyo. Ngokuqhelekileyo Rostovka Bicycle okhethwe intshi (amanani), ubuncinane - ngokweesentimitha. Kwakhona boonobumba ezinokusetyenziswa. Kodwa ke yeyona ngokubanzi iza kukhangeleka ngolu hlobo:

Kakade ke, lo ngumlinganiselo zithathelwa avareji. Ukuchaneka abanakulindelwa ukuba aphindwe. Noko ke, abanye bafumane indlela yabo lulwandle yorhwebo eziya kunceda. Ulwazi ubuncinane umlinganiselo elisondeleyo Ubude bomzimba kunye nobude yesakhelo unciphise kakhulu uluhlu lophendlo.

Ukukhetha Rostovka isithuthuthu ngokuxhomekeke kuhlobo bekhwele

ifreyim ukuphakama iya kwahluka kungekuphela ngenjongo ibhayisikile, kodwa kwisimbo, iimeko ezicwangcisiweyo yokusebenza uqhuba. Kwaye kulula okanye uhlobo sihambe igqiba Rostovka ibhayisekile. Le theyibhile iya kunceda ukuqinisekisa ukhetho. Ngoko ke, ekuhambeni ukuphumla ezidolophini unako ukuthenga umhlobo enamavili amabini ekupheleni eliphezulu. Ngokomzekelo, ebudeni ukukhula 160 cm intshi-18 ibhayisekile kakhulu ukhululekile ukuba okusingqongileyo kwedolophu. Ke lokuqhuba silwe, ezisezintabeni kunye nezinye izinto ezinzima kubhetele ukusebenzisa ihashe yentsimbi compact ngakumbi kwisakhelo intshi-16 okanye ngaphantsi.

Olunye ukhetho Rostovka: ubungakanani wheel

abavelisi zibonisa ubukhulu lwevili yaye ngokufuthi. Kuxhomekeka ubukhulu zonke Bikes angohlulwa abe abantwana kunye nabantu abadala. Udidi lokuqala luquka amavili ngobubanzi ukusuka intshi-12 ukuya kuma-24. 20-24 intshi sele ingqalelo elivisayo. Phela, abadala yokukhula ndikhwele kakuhle ngezi imifuziselo, okt. K. A ihashe nentsimbi kwi kwandisa ivili enkulu ngooceba abanyulwe kwisakhelo, umgama ukuya steering kunye nazo zonke ezinye iparameters.

26 no-29 intshi - ubukhulu ofanayo Bikes ezintabeni abadala. Inani 28 isoloko ifumaneka imifanekiso, eyenzelwe zokukhwela ezidolophini.

Indlela ukufumanisa ukuphakama ngokupheleleyo iinqwelo ibhayisekile

Mhlawumbi oku kuphela ukhetho okulawulwayo. imodeli Onge, apho ukuphakama kwesihlalo kuhlala ingatshintshanga kwaye ixhomekeke Rostovka ibhayisekile. Ukumisela indawo eliphezulu ungakwazi empirically kuphela. Behleli iinqwelo kufuneka ukuzitshintsha ihamba. Ingongoma liphantsi yomlenze kufuneka onokolula ngokupheleleyo kodwa kuhlala bent kancinane (hayi ngaphezu kweqondo lama-160). Phezulu womlenze ukuze zilahlwe tyaba, zibhekisela emhlabeni yaye kuba lula kancinci phantsi. Le amadolo ingaphumi, ngaphezu isinqe. Oku kubonisa ukuba iinqwelo iphantsi kakhulu.

esezimpondweni ukuphakama

Xa isigqibo esihlalweni, ukufudukela ivili lokuqhuba, oko kukuthi. To. Indawo sabo ezihambelanayo. Ukuze ubone ubude amalungu ebhayisikile indima ephambili iza kudlala indlela anyuliweyo Ukuskiya.

Kuba imizila uhlanga nesantya drive ivilana ebekwe ngezantsi kwesihlalo-10 cm., Kuxhomekeka kwiimpawu ngamnye ka-3 cm.

Ngokuba uqhuba ndlongondlongo kunye nokhenketho efanayo, xa kujongwe ukuba boyise imiqobo ezahlukeneyo, ekhwela kunye ekwehleni, ivili kufuneka 2-6 cm ngezantsi isihlalo. Kuba abantu abadala kuvunyelwa ukufaka kubo kwinqanaba elifanayo.

Lokuhlola umzi, emendweni yaye ekhwele flat ivili imizila steering kufuneka ibekwe ngaphezu isali okanye kwinqanaba elifanayo.

Ububanzi iinqwelo

Enye parameter apho umkhweli bebefudula ihlawulwe ingqalelo encinane. Nangona kwafuneka ingako yakwenza nombuzo Rostovka ibhayisekile, oko kulilize ungayihoyi loo nto, loo nto. To. Of izihlalo ezitofotofo kuxhomekeke kwizinto ezininzi. Ukuba libanzi kakhulu, ngoko kukho zokuphonononga iintshukumo zinganxitywa, kunye ezinqeni umva ephantsi uqale ukuba buhlungu. akhwela engafanelekanga kungabangela iingxaki ezahlukeneyo zempilo. Ukuba libanzi kakhulu, lo enyovwayo uya kuba kugula, oko kukuthi. A. ethangeni akayi kuba nako ukuhamba ngokukhululekileyo. tuberosity Ischial kufuneka ningaweli kumathambeka, kwaye iflethi isihlalo buthelezi. Ke andiyi kubuzisa ukungakhululeki kuwa phakathi ezimpundwini, bezihlikihla njalo njalo. D.

Fumanisa kude kangakanani ngaphandle ke tuberosity ischial, ngolu hlobo lulandelayo: kufuneka uhlale phezu kwentlabathi egudileyo, uze balinganise umgama phakathi misinga zinzulu. Oku kuya kuba ububanzi kangangoko. Kufuneka kukhunjulwe ukuba abasetyhini isinqe mkhulu kunabantu. Ngako oko Bikes kubantu besini ezifanelekileyo na imibala kuphela kodwa ububanzi kwesihlalo.

Kuba ukuthenga Kulungile ukuya kwivenkile elithile. Apha, abathengisi abanamava ndithi kuni indlela ukhethe Rostovka ibhayisekile zonke iimpawu umntu ekufuneka bezisebenzisile ekhwele isimbo.
