Isithuthuthu
Khawube nomfanekiso-ngqondweni ubhabhela kwiindawo ezibukekayo, uziva umoya ezinweleni zakho, kwaye wamkele uyolo lohambo lwangaphandle. Eli lihlabathi le-21-speed e-bikes, apho iteknoloji yokusika idibana novuyo lokuhamba ngebhayisikili. Nokuba ungumkhweli onamava ofuna i-push eyongezelelweyo okanye i-novice enqwenela uthando olutsha, ezi bhayisekile zombane zibonelela ngendlela evuyisayo kunye ne-eco-friendly yokuhlola izinto ezintle ngaphandle.
Uninzi lwee-e-bikes zixhotyiswe ngamagiya ukunceda umkhweli ajongane neendawo ezahlukeneyo. Iigiya eziqhelekileyo kwii-e-bikes ziquka i-1, i-3, i-7, i-18 kunye ne-21 isantya, kunye nesantya ngasinye sibhekiselele kwindibaniselwano eyahlukileyo yezixhobo. Ngokutshintsha indibaniselwano yezi giyeri, unokwenza ukunyovwa kube nzima okanye kube nzima.
Masiqalise – silapha ukukuxelela yonke into ekufuneka uyazi malunga nokutshintsha i-21-speed e-bike yakho!
Yintoni i-21-speed e-bike?
I-21-speed e-bike ingaba naluphi na uhlobo lwe-e-bike kunye ne-21 gears, nokuba yindlela ye-e-bike, i-e-bike yentaba, i-e-bike okanye i-hybrid e-bike.
Ngokutsho kwabavelisi be-e-bike, i-21-speed e bike ngokuqhelekileyo inikezela ngokukhawuleza, ukuhamba ngokukhawuleza kune-e-bike yesantya esisezantsi. Kodwa ngokutshoyo, iigiya zayo ezahlukeneyo ziyakuvumela ukuba ukhwele ngesantya esicothayo, amandla apheleleyo, okanye nantoni na phakathi.
Ukufumana ulwazi oluthe kratya lobugcisa, i-ebike ye-21-speed ine-3 i-gear yangaphambili kunye ne-7 gear yangasemva. I-cogs yangaphambili ibekwe kumgca othe ngqo kunye neepedali, ezibizwa ngokuba yi-chainring. Iigiya ezingasemva zilele kumgca othe tye kunye ne-asi yevili elingasemva, ngokudibeneyo eyaziwa ngokuba yi-cassette flywheel, kwaye yaziwa ngabanye njenge-cogwheel (igiya).
Iidiski zekhasethi ezinkulu nezincinci zifanelekile kwiindawo ezigqithiseleyo: iinduli ezinkulu okanye ukuhamba ngokukhawuleza kwendlela. Ngokutsho kwabavelisi be-e-bike, ukutshintsha i-e-bike yakho kwiigiya eziphantsi kakhulu kwenza ukunyuka kube lula, kwaye ukutshintshela kwiigiya eziphezulu kwenza ukuhla ngokukhawuleza. (Siza kuxubusha oku ngokubanzi ngezantsi.)
Musa ukusebenzisa i-disc encinci eneyona giya incinci kwi-flywheel okanye idiski enkulu enesixhobo esikhulu. (Ngokwemiqathango ye-layman, oku kubizwa ngokuba yi-“cross-chaining.”) Oku kuya kubangela ukuba ikhonkco lijike kakhulu, ukunyuka nokukrazuka kwe-e-bike kunye nokwandisa umngcipheko wokutsiba kwetsheyini kwii-cogs ngelixa ukhwele.
Iinxalenye ezi-5 eziphambili ze-21-speed ibhayisikili
I-Flywheel: Iseti yeegiya (iicogs) ezibekwe kwivili elingasemva le-e-bike.
Itsheyini: Ikhonkco lentsimbi elidibanisa ikhonkco langaphambili kwi-flywheel ukuze xa ujika iipedali, ivili nalo liyajika.
I-Crankset: Inxalenye ye-e-bike edibanisa iipedali. Ihambisa amandla ukusuka kumkhweli ukuya kwivili elingasemva. Iibhayisikili ze-e-speed ze-21 zihlala zineediski ezintathu kwi-crankset.
Shifter: Indlela elawulwa sisishifter esihambisa ikhonkco le-e-bike ukusuka kwenye icog ukuya kwenye. Uninzi lwee-e-bikes zine-derailleur yangasemva ngasemva, kodwa ayizizo zonke ii-e-bikes ezine-front derailleur.
Shifter: Ulawulo olubekwe kwii-handlebars ze-e-bike yakho (ngentambo esebenza kwi-chainstay) evumela ukuba utshintshe iigiya.
Indlela yokusebenzisa i-21-speed e-bike
Kunzima ukonwabela ukukhwela ibhayisekile ye-e-bhayisekile xa ungakwazi ukuhambisa iipedali okanye xa iipedali zijikeleza ngokukhawuleza ukuba iinyawo zakho zikwazi ukuqhubeka. Ukulungelelanisa igiya kwi-e-bike yakho kukuvumela ukuba ugcine isingqisho osithandayo sokunyovwa nangasiphi na isantya.
I-chainstay isetyenziselwa ukutshintsha phakathi kweegiya. I-chainstay ilawulwa yi-shifter efakwe kwii-handlebars. Ngokuqhelekileyo, i-shifter yasekhohlo ilawula i-brake yangaphambili kunye ne-derailleur yangaphambili (i-chainring yangaphambili), kwaye i-shifter yasekunene ilawula i-brake yangasemva kunye ne-derailleur yangasemva (i-chainring yangasemva). I-shifter itshintsha indawo ye-toggle, ibangela ukuba ikhonkco liphume kwi-cog yangoku kwaye lixhumele kwi-cog elandelayo enkulu okanye encinci. Uxinzelelo lwe-pedal oluqhubekayo luyafuneka ukutshintsha iigiya.
Iigiya ezisezantsi (okokuqala ukuya kweyesixhenxe) zezona zilungele ukunyuka iinduli. I-cog ephantsi kakhulu kwi-e-bike yeyona nto incinci ikhonkco ngaphambili kunye ne-cog enkulu kwi-flywheel. Downshift kule ndawo xa ufuna eyona pedaling ilula ngokuxhathisa okuncinci.
Iigiya ezinesantya esiphezulu (iigiya ezili-14 ukuya kuma-21) zezona zilungele ukuhla. Esona sixhobo siphezulu kwibhayisekile ye-e yeyona nto inkulu ngaphambili kunye neyona sixhobo sincinci kwi-flywheel. Upshift kule ndawo xa ufuna ukunyola eyona inzima kunye neyona nto ixhathisayo - ilungele ukukhawulezisa ukuhla.
Unokukhetha njani igiya efanelekileyo ye-21-speed e-bike yakho
Kuba ii-e-bikes ezinesantya esingama-21 ziza ngeentlobo ngeentlobo zeegiya, kuya kufuneka uzame ukuba yeyiphi igiya ekulungeleyo kwiintlobo ezahlukeneyo zomhlaba – emva kwayo yonke loo nto, wonke umntu wahlukile kwaye akukho mntu unokhetho olufanayo.
Khetha i-gear oziva ukhululekile kuyo. Qala nge-disc ephakathi kunye ne-medium gear kwi-flywheel, kunye ne-21-speed electric e-bike gear yesine. Ngelixa uqhubeka nokunyola, yenza uhlengahlengiso oluncinci kwishifter yasekhohlo ukulungisa i-flywheel.
Ukukhawulezisa i-cadence, khetha i-cog encinci, njenge-cog 5, 6 okanye i-7 kwi-21-speed e-bike. Ukunciphisa i-cadence, khetha igiya enkulu, njengenombolo yokuqala, ezimbini okanye ezintathu. Ukuba inombolo yegiya enye okanye isixhenxe ayikhawulezi okanye icotha ngokwaneleyo kuwe, hambisa i-flywheel ubuyisele kwinombolo yesine kwaye ulungise ikhonkco. Kwakhona, qhubeka unyoba ngelixa uhambisa iigiya.
Nazi ezinye iingcebiso zokwenza uninzi lotshintsho lwezixhobo zakho.
- Lindela utshintsho lwezixhobo kwangaphambili
Qala ukucinga malunga nokutshintsha iigiya ngaphambi kokuba ufikelele kumqobo, njengenduli. Ukuba ulinda ude ube phakathi kwenduli kwaye ungacinezeli iipedali, ukutshintsha iigiya kuya kuba nzima. Cinezela ngobunono i-pedal iirevolution ezimbalwa ngelixa uhambisa iigiya. Uxinzelelo oluninzi luya kuthintela i-cogs ukuba ingaguquki, okanye iya kubangela ukuba i-pawl ye-chain itsibe iigiya, okukhokelela ekugugeni phakathi kwekhonkco kunye ne-pawl. - Ungalibali ukutshintshela kwigiya elula xa usondela kwindawo yokumisa
Ukuba uqhuba kwindawo ethe tyaba okanye unomsila wokutyhalela phambili, mhlawumbi usebenzisa eyona giya inzima. Oku kulungile de ume kwaye uzame ukuqhuba ngegiya enye kwakhona. Ukwehlisa iigiya ezimbalwa njengoko usondela kwindawo yokumisa kwenza kube lula ukufumana amandla kwakhona.
Iingcebiso zokutshintsha izixhobo ezilula
Ukwenza igiya yakho ikusebenzele, tshintshela kwigiya elula xa usiya kwindawo enyukayo okanye uqala ukudinwa. Ukuba i-cadence yakho iqala ukuhla nangasiphi na isizathu, thatha oku njengophawu lokutshintshela kwisixhobo esilula. Ngakolunye uhlangothi, sebenzisa iiflethi, ukuhla kunye ne-tailwinds ukutshintshela kwisixhobo esinzima. Oku kuya kukuvumela ukuba ukwandise isantya sakho ngelixa ugcina i-cadence efanayo kunye nenqanaba lokuhamba.
