While this inner tube is specified for 20 x 4.0\/4.9 tyres, checking your tyre's exact markings is crucial. Also, confirm that your wheel rim is designed for a Schrader valve and that the valve hole accommodates the 32mm valve length.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and Safety Guidance\u003c\/h3\u003e\n\u003cp\u003eWhen installing the inner tube, ensure the tyre is fully deflated. Carefully insert the valve through the rim hole and secure it with the nut. Partially inflate the tube to give it shape before seating the tyre beads evenly on the rim. Before full inflation, check for any pinching of the inner tube between the tyre bead and the rim. Inflate to the pressure recommended by your tyre manufacturer, typically found on the tyre sidewall. After installation, inspect both sides of the tyre to confirm it is properly seated on the rim.\u003c\/p\u003e","brand":"ULIP","offers":[{"title":"Default Title","offer_id":64137542697337,"sku":"ULP2842.00","price":19.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0902\/7076\/1337\/files\/chaoyang-inner-tube-20x4-0-4-9-for-engwe-engine-pro-3-0-boost-electric-bicycle-01.webp?v=1785602470","url":"https:\/\/www.evolt.eu\/cs\/products\/inner-tube-chaoyang-20x4-04-9-for-electric-bike-engwe-ep-2-pro","provider":"eVolt.eu","version":"1.0","type":"link"}
