{"product_id":"vtuvia-cmb-8-speed-ebike","title":"VTUVIA CMB Pro 8-Speed Electric Bike","description":"\u003cp\u003eThe VTUVIA CMB Pro is an upright step-through e-bike built for riders who want mid-drive response without a high top tube. Its 500W mid-drive motor sends power through an 8-speed Shimano drivetrain, so the motor can use the bike's gears on climbs. VTUVIA publishes up to 820W peak output and 175 Nm of torque. Those numbers explain why the CMB Pro belongs on a hillier shortlist, but gearing, cadence and rider input still determine how naturally it moves.\u003c\/p\u003e\u003cp\u003eAt about 60 lb fully equipped, the CMB Pro is easier to maneuver than many fat-tire utility bikes, but it is not a light carry-upstairs bicycle. The 26 x 2.6-inch tires, 100 mm suspension fork, rear rack, fenders and adjustable cockpit favor daily comfort and practical errands. If your route crosses Seattle grades, Pittsburgh neighborhoods or rolling Denver streets, the mid-drive layout is the reason to compare it. Measure the storage path and confirm local route rules before ordering.\u003c\/p\u003e\u003ch2\u003eWho this bike fits\u003c\/h2\u003e\u003cp\u003eChoose the CMB Pro when you want a low-step commuter with strong hill-start support, an upright fit and conventional bicycle gearing. VTUVIA recommends it for riders about 5 ft 1 in to 6 ft 1 in, with a published 300 lb total capacity. The adjustable stem and seat help refine the fit, but inseam, reach and confident starts matter more than height alone.\u003c\/p\u003e\u003cp\u003eChoose another model if you need a compact folder, three-wheel stability at stops or a bike you can lift casually. The CMB Pro rewards riders who shift before a climb and keep the drivetrain maintained. A hub-motor bike can be simpler for someone who never wants to think about gear choice under load.\u003c\/p\u003e\u003ch2\u003eMotor, gears and handling\u003c\/h2\u003e\u003cp\u003eVTUVIA lists a 500W mid-drive motor, up to 820W peak output and 175 Nm of torque. A torque sensor reads pedal pressure, while the cadence sensor and thumb throttle provide additional control paths. The delivered bike is presented as a Class 2 configuration. Confirm the exact local rules before using a throttle on public streets, paths or campuses.\u003c\/p\u003e\u003cp\u003eThe Shimano 8-speed drivetrain gives you a useful low gear for starts and grades. Shift before the drivetrain is heavily loaded, ease pedal pressure during a shift and keep the chain clean. Hydraulic disc brakes and the 100 mm suspension fork support an urban setup, but stopping distance still changes with speed, load, weather, pad condition and tire grip.\u003c\/p\u003e\u003ch2\u003eBattery and real route planning\u003c\/h2\u003e\u003cp\u003eThe removable 48V 14.4Ah LG battery stores about 691Wh. VTUVIA publishes favorable-condition maximums of up to 80 miles with pedal assist and up to 45 miles using throttle. Treat those as comparison figures, not a promised commute. Hills, cold weather, frequent starts, tire pressure, rider load and assistance level can shorten the route substantially.\u003c\/p\u003e\u003cp\u003eVTUVIA lists about 7.5 hours for a full charge. Use only the supplied compatible charger, charge in a dry and ventilated area while you are present, and let the battery cool after a demanding ride. For the first week, plan a shorter loop and note your battery use before committing to a long round trip.\u003c\/p\u003e\u003ch2\u003eSafety and route fit\u003c\/h2\u003e\u003cp\u003eVTUVIA's current product page identifies UL 2271 for the battery and UL 2849 for the e-bike system. If a building, insurer or campus requires documentation, request the exact model record before ordering rather than relying on a product-page statement alone.\u003c\/p\u003e\u003cp\u003eWear a properly fitted helmet, check both brakes and tires before every ride, and learn the throttle and assist response away from traffic. The rack and 300 lb published capacity do not automatically approve every child seat, passenger setup or accessory. Follow the accessory maker's limits and local passenger rules.\u003c\/p\u003e\u003ch2\u003eSetup, service and support\u003c\/h2\u003e\u003cp\u003eInitial setup should end with a professional-quality check of the handlebar, front wheel, pedals, hydraulic brakes, derailleur, battery lock, lights, rack and fenders. The CMB Pro video selected on this page is an independent hands-on review of the 8-speed version. It adds useful riding context, but it does not replace the manual or a mechanic's inspection.\u003c\/p\u003e\u003cp\u003eStreetRides return policy applies to your order. StreetRides coordinates eligible manufacturer-warranty requests under VTUVIA's written terms, but does not promise a particular claim outcome. Keep the carton, serial number and delivery photos until setup and the first inspection are complete.\u003c\/p\u003e\u003ch2\u003ePublished specifications\u003c\/h2\u003e\u003cp\u003eMotor: 500W mid-drive, up to 820W peak and 175 Nm published. Battery: removable 48V 14.4Ah LG, about 691Wh. Drivetrain: Shimano 8-speed. Sensors: torque and cadence. Tires: 26 x 2.6 inches. Suspension: 100 mm front fork. Brakes: hydraulic disc. Display: 3.5-inch LCD. Weight: about 60 lb fully equipped. Capacity: 300 lb. Recommended rider height: 5 ft 1 in to 6 ft 1 in. Published charge time: about 7.5 hours.\u003c\/p\u003e\u003ch2\u003eThe StreetRides view\u003c\/h2\u003e\u003cp\u003eThe CMB Pro makes its strongest case on hilly everyday routes. A mid-drive motor, torque sensing and eight usable gears give you more control over climbs than a simple one-speed power story.\u003c\/p\u003e\u003cp\u003eIts tradeoff is drivetrain responsibility. Shift well, maintain the chain and buy it for the route you actually ride. If easy mounting and hill response matter more than folding or three-wheel balance, this is the more coherent VTUVIA choice.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/vtuviaebike.com\/products\/cmb-mid-drive-500-watt-electric-city-bike-vtuvia-ebike\" target=\"_blank\" rel=\"noopener\"\u003eReview the official VTUVIA CMB Pro product information\u003c\/a\u003e.\u003c\/p\u003e","brand":"VTUVIA","offers":[{"title":"Metallic Silver","offer_id":43256891965502,"sku":"CMB-Pro-silvery-8s","price":1899.0,"currency_code":"USD","in_stock":true},{"title":"Dark blue","offer_id":43256891998270,"sku":"CMB-Pro-blue-8s","price":1899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/4503\/1998\/files\/CMB_PRO_CHAIN-_silver.png?v=1788163870","url":"https:\/\/streetrides.us\/products\/vtuvia-cmb-8-speed-ebike","provider":"StreetRides US","version":"1.0","type":"link"}
