ibhayisikili
Zibone ngeso lengqondo untweza kalula ezindaweni ezinhle, uzwa umoya ezinweleni zakho, futhi wamukela injabulo yohambo lwangaphandle. Lona umhlaba wamabhayisikili e-e-speed angu-21, lapho ubuchwepheshe obusezingeni eliphezulu buhlangabezana nenjabulo yokugibela ibhayisikili. Kungakhathaliseki ukuthi ungumgibeli ongumakadebona ofuna ukusunduzwa okwengeziwe noma u-novice ofisa uthando olusha, lawa mabhayisikili kagesi anikeza indlela ejabulisayo neco-friendly yokuhlola izinto ezinhle ngaphandle.
Amabhayisikili amaningi e-elekthronikhi afakwe amagiya ukusiza umgibeli ukuthi abhekane nezinhlobonhlobo zezindawo. Amagiya ajwayelekile kuma-e-bikes afaka isivinini esingu-1, 3, 7, 18 kanye no-21, isivinini ngasinye sisho inhlanganisela ehlukile yamagiya. Ngokushintsha inhlanganisela yala magiya, ungenza uku-pedaling kube nzima kakhulu.
Masiqalise - silapha ukuze sikutshele konke odinga ukukwazi mayelana nokushintsha ibhayisikili lakho le-e-speed engu-21!
Yini i-e-bike engama-21-speed?
Ibhayisikili le-e-speed engu-21 ingaba yinoma yiluphi uhlobo lwe-e-bike elinamagiya angu-21, kungakhathaliseki ukuthi i-e-bike yomgwaqo, i-e-bike yentaba, i-e-bike noma i-hybrid e-bike.
Ngokusho kwabakhiqizi be-e-bike, ibhayisikili le-e-speed engu-21 ngokuvamile linikeza ukugibela okusheshayo, okushelelayo kune-e-bike enesivinini esiphansi. Kodwa njengoba sekushiwo, amagiya ayo ahlukahlukene akuvumela ukuthi ugibele ngesivinini esiphansi, amandla aphelele, nanoma yini ephakathi.
Ukuze uthole ulwazi olwengeziwe lobuchwepheshe, i-21-speed ebike inamagiya angu-3 angaphambili namagiya angu-7 angemuva. Ama-cogs angaphambili atholakala emugqeni oqondile nama-pedals, abizwa ngokuthi i-chainring. Amagiya angemuva alale emugqeni oqondile ne-asi yesondo elingemuva, aziwa ngokuhlanganyela ngokuthi i-cassette flywheel, futhi aziwa ngawodwa ngokuthi yi-cogwheel (igiya).
Ama-cassette discs amakhulu namancane afaneleka ezindaweni ezimbi kakhulu: amagquma amakhulu noma ukugibela umgwaqo osheshayo. Ngokwabakhiqizi be-e-bike, ukushintsha i-e-bike yakho iye kumagiya aphansi kakhulu kwenza ukukhuphuka umqansi kube lula, futhi ukushintshela kumagiya aphezulu kwenza ukwehla ngokushesha. (Sizoxoxa ngalokhu ngokuningiliziwe ngezansi.)
Ungasebenzisi idiski elincane elinegiya elincane ku-flywheel noma idiski elikhulu elinegiya elikhulu kunawo wonke. (Ngokwegama le-layman, lokhu kubizwa ngokuthi “i-cross-chaining.”) Lokhu kuzodala ukuthi iketango lijike kakhulu, kukhuphule ukuguga nokudabuka ku-e-bike futhi kwandise ingozi yokuthi iketango ligxume lisuka kuma-cogs ngenkathi ligibele.
Izingxenye ezi-5 eziyinhloko ze-21-speed ibhayisikili kagesi
I-Flywheel: Isethi yamagiya (ama-cogs) atholakala esondweni elingemuva le-e-bike.
Iketango: I-metal linkage ehlanganisa iringi yangaphambili ne-flywheel ukuze uma uphendula amaphedali, isondo nalo liyajika.
I-Crankset: Ingxenye ye-e-bike ehlanganisa amaphedali. Idlulisa amandla ukusuka kumgibeli iye esondweni elingemuva. Amabhayisikili e-e-speed kagesi angu-21 ngokuvamile anamadiski amathathu ku-crankset.
I-Shifter: Indlela elawulwa yi-shifter ehambisa iketango le-e-bike lisuka kwelinye igiya liye kwelinye. Amabhayisikili amaningi ane-derailleur engemuva ngemuva, kodwa akuwona wonke ama-e-bike ane-derailleur yangaphambili.
I-Shifter: Isilawuli esitholakala kuzibambo zebhayisikili lakho le-e (ngekhebula esebenzisa i-chainstay) ekuvumela ukuthi ushintshe amagiya.
Isetshenziswa kanjani i-e-bike engama-21-speed
Kunzima ukujabulela ukugibela i-e-bike lapho ungakwazi ukunyakazisa amaphedali noma lapho amaphedali ephenduka ngokushesha kakhulu ukuze izinyawo zakho ziqhubeke. Ukulungisa igiya ku-e-bike yakho kukuvumela ukuthi ugcine isigqi sakho sokunyathela osithandayo nganoma isiphi isivinini.
I-chainstay isetshenziselwa ukushintsha phakathi kwamagiya. I-chainstay ilawulwa yi-shifter efakwe kuzibambo. Ngokuvamile, i-shifter yesokunxele ilawula ibhuleki langaphambili ne-derailleur yangaphambili (i-chainring yangaphambili), futhi i-shifter yesokudla ilawula ibhuleki elingemuva ne-rear derailleur (i-rear chainring). I-shifter ishintsha indawo ye-toggle, ibangele ukuthi iketango lihlehle ukusuka ku-cog yamanje futhi ligxumele ku-cog elandelayo enkulu noma encane. Ukucindezela okuqhubekayo kwe-pedal kuyadingeka ukuze ushintshe amagiya.
Amagiya aphansi (okokuqala kuye kwelesikhombisa) angcono kakhulu ekukhuphukeni amagquma. I-cog ephansi kunazo zonke ku-e-bike iketanga elincane kunawo wonke ngaphambili kanye ne-cog enkulu ku-flywheel. I-downshift ukuya kulesi sikhundla uma ufuna ukuhamba ngezinyawo okulula kunokumelana okuncane.
Amagiya ejubane eliphezulu (amagiya angu-14 kuya ku-21) angcono kakhulu ekwehleni. Igiya eliphakeme kakhulu ku-e-bike iketanga elikhulu kunawo wonke ngaphambili kanye negiya elincane ku-flywheel. Khuphukela kule ndawo uma ufuna ukunyathela okunzima kakhulu futhi ukumelana kakhulu - ilungele ukusheshisa ukwehla umqansi.
Ungalikhetha kanjani igiya elifanele lebhayisikili lakho le-e-speed engu-21
Ngenxa yokuthi amabhayisikili e-e-speed angu-21 afika ngamagiya ahlukahlukene, kuzomele uzame ukuthi yimaphi amagiya akufanelekela kangcono ezinhlotsheni ezahlukene zendawo - phela, wonke umuntu uhlukile futhi akekho onezintandokazi ezifanayo.
Khetha igiya ozizwa ukhululekile kulo. Qala ngediski elimaphakathi negiya elimaphakathi ku-flywheel, bese ku-21-speed e-bike kagesi igiya lesine. Ngenkathi uqhubeka nokunyathela, yenza ukulungisa okuncane kusishintshi esingakwesokunxele ukuze ulungise i-flywheel.
Ukuze usheshise i-cadence, khetha i-cog encane, njenge-cog 5, 6 noma 7 ngebhayisikili ye-e-speed engu-21. Ukuze unciphise i-cadence, khetha igiya elikhudlwana, njengenombolo yokuqala, amabili noma amathathu. Uma igiya lokuqala noma lesikhombisa lingasheshi noma lingasheshi ngokwanele kuwe, buyisela i-flywheel egiyeni lesine bese ulungisa i-chainring. Futhi, qhubeka u-pedaling ngenkathi ushintsha amagiya.
Nawa amanye amathiphu okwenza okuningi ngoshintsho lwegiya lakho.
- Lindela izinguquko zegiya kusenesikhathi
Qala ukucabanga ngokushintsha amagiya ngaphambi kokuba ufinyelele isithiyo, esifana negquma. Uma ulinda uze ukhuphuke uhhafu wegquma bese ungacindezeli amaphedali, ukushintsha amagiya kuzoba nzima. Cindezela kancane i-pedal ama-revolution ambalwa ngenkathi ushintsha amagiya. Ukucindezela okukhulu kuzovimbela ama-cogs ukuthi angagudluki, noma kuzobangela ukuthi i-chain pawl yeqe amagiya, okuholela ekugugeni phakathi kweketango ne-pawl. - Ungakhohlwa ukushintshela egiyeni elilula uma usondela esitobhini
Uma ushayela endaweni eyisicaba noma unomoya womsila ukuphushela phambili, cishe usebenzisa elinye lamagiya anzima kakhulu. Lokhu kulungile uze ume bese uzama ukushayela ngegiya elifanayo futhi. Ukwehlisa amagiya ambalwa njengoba usondela esitobhini kwenza kube lula ukubuyisela amandla.
Amathiphu okushintsha amagiya lula
Ukuze wenze igiya lakho likusebenzele, shintshela egiyeni elilula lapho usondela ekukhuphukeni noma uqala ukukhathala. Uma i-cadence yakho iqala ukwehla nganoma yisiphi isizathu, thatha lokhu njengophawu lokushintshela egiyeni elilula. Ngakolunye uhlangothi, sebenzisa amafulethi, owehlayo kanye nezivunguvungu zangemuva ukuze ushintshele egiyeni eliqinile. Lokhu kuzokuvumela ukuthi ukhuphule isivinini sakho ngenkathi ugcina i-cadence efanayo nezinga lokunyakaza.
