{"product_id":"cyrusher-zenith","title":"Cyrusher Zenith","description":"\u003cp\u003eThe Cyrusher Zenith is the step-over version of the brand's 26-inch fat-tire platform, built around an aluminum diamond frame for riders who prefer a traditional top tube and the stiffer feel that comes with it. Its 52V 750W brushless rear motor is rated at 95 Nm of maximum torque, enough to move a loaded bike up a climb without the rider having to work the gears aggressively. Four-inch tires on 26-inch wheels give the bike a wide, flat contact patch, so it tracks predictably on gravel roads, dirt paths and soft ground as well as on pavement.\u003c\/p\u003e\u003cp\u003eA 52V 15Ah battery using LG 21700 cells supplies 780Wh and is quoted at up to 60 miles per charge. That ceiling assumes light assist and easy terrain; hills, headwinds, a heavier load or frequent throttle use will bring it down. Filling an empty pack takes roughly seven to eight hours at 2A. The pedal-assist system can be switched between torque and cadence sensing, letting the rider pick between assist proportional to pedaling effort and assist that engages as soon as the pedals move. Drive is through a Shimano 1x7 setup with a TY500 rear derailleur.\u003c\/p\u003e\u003cp\u003eBraking is handled by Logan two-piston hydraulic calipers on 180mm discs, which is worth noting on a bike that weighs 34.3 kg, or about 75.6 pounds, before any cargo. The frame accepts riders from 5'1\" to 6'4\" and is rated for a 350-pound payload. Suspension is front only: the specification sheet lists a front unit with a coil-spring fork and names no rear shock or rear travel, so the Zenith is a hardtail in practice. A mid-mounted color LCD shows speed, assist level and battery state, lighting front and rear is fitted as standard, and the bike is rated IPX5 with some components rated IPX7.\u003c\/p\u003e\u003cp\u003eCyrusher lists SGS certification to UL 2849 and UL 2271. Because assist continues to 28 mph and the motor is rated at 750W, the bike sits in the higher-powered category that many jurisdictions regulate separately. Whether you may ride it on a given road, bike lane, sidewalk or multi-use trail, and whether a helmet or a minimum rider age applies, is decided by your state and your local authority, so confirm those rules for your own area before your first ride. Fenders and a rear rack come as a separate accessory set, and several accessories are listed as fitting both the Zenith and the step-through frame.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFit, Colors and Accessories\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFrame: aluminum step-over diamond, listed for riders 5'1\"-6'4\"\u003c\/li\u003e\n\u003cli\u003ePayload capacity: 350 lbs\u003c\/li\u003e\n\u003cli\u003eBike weight: 34.3 kg (about 75.6 lbs); battery 4.5 kg\u003c\/li\u003e\n\u003cli\u003eColor options: Green, Silver and Grey\u003c\/li\u003e\n\u003cli\u003eA step-through frame version of the same platform is sold separately\u003c\/li\u003e\n\u003cli\u003eFenders and a rear rack are offered as an accessory set rather than standard equipment\u003c\/li\u003e\n\u003cli\u003eCyrusher lists a suspension seat post and the fender and rack set as fitting both the Zenith and the step-through frame\u003c\/li\u003e\n\u003cli\u003eAn assembly video and a written guide cover the setup required at delivery\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cyrusher","offers":[{"title":"Green","offer_id":67886707703999,"sku":"Zenith-Green","price":1099.0,"currency_code":"USD","in_stock":true},{"title":"Silver","offer_id":67886707736767,"sku":"Zenith-Silver","price":1099.0,"currency_code":"USD","in_stock":true},{"title":"Grey","offer_id":67886707769535,"sku":"Zenith-Grey","price":1099.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/1967\/6351\/files\/Cyrusher-Zenith-Fat-Tire-E-Bike-Main-Green-1_69fb617a-a91f-4652-8a7a-e3060d8f995c.jpg?v=1793884792","url":"https:\/\/adventuremotion.com\/products\/cyrusher-zenith","provider":"Adventure Motion","version":"1.0","type":"link"}
