Compared to the 4T, the 3.5T is designed to prioritize top-end speed and can add roughly 10–15 mph of additional top speed potential depending on your setup. With a stock battery and controller, expect more speed with less low-end torque, but you can recover some acceleration by adjusting your controller settings (for example, acceleration timing and power output limits within safe operating ranges). The wider rim also supports a wider rear tire for a more planted look and feel, including up to a 4-inch tire fitment depending on tire model and clearance.\u003c\/p\u003e\n\u003cp data-start=\"1609\" data-end=\"1711\"\u003e\u003cstrong data-start=\"1609\" data-end=\"1622\"\u003eBest for:\u003c\/strong\u003e higher top speed, wider tire look, riders willing to tune settings for the best balance.\u003c\/p\u003e\n\u003ch3 data-start=\"1713\" data-end=\"1773\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eQuick decision guide\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul data-start=\"1774\" data-end=\"2049\"\u003e\n\u003cli data-start=\"1774\" data-end=\"1878\"\u003e\n\u003cp data-start=\"1776\" data-end=\"1878\"\u003eChoose \u003cstrong data-start=\"1783\" data-end=\"1800\"\u003e4T (1.6\" rim)\u003c\/strong\u003e if you want the \u003cstrong data-start=\"1817\" data-end=\"1835\"\u003estock 72V feel\u003c\/strong\u003e with \u003cstrong data-start=\"1841\" data-end=\"1875\"\u003estrong torque and acceleration\u003c\/strong\u003e.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1879\" data-end=\"2049\"\u003e\n\u003cp data-start=\"1881\" data-end=\"2049\"\u003eChoose \u003cstrong data-start=\"1888\" data-end=\"1907\"\u003e3.5T (2.5\" rim)\u003c\/strong\u003e if you want \u003cstrong data-start=\"1920\" data-end=\"1948\"\u003emore top speed potential\u003c\/strong\u003e and a \u003cstrong data-start=\"1955\" data-end=\"1980\"\u003ewider rear tire setup\u003c\/strong\u003e, and you’re comfortable with \u003cstrong data-start=\"2010\" data-end=\"2026\"\u003elight tuning\u003c\/strong\u003e to regain some torque.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0719\/1678\/1816\/files\/ONYXRCR72V-RearWheelHubMotorAssemblyV2.5-02.jpg?v=1781120786\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0719\/1678\/1816\/files\/ONYXRCR72V-RearWheelHubMotorAssemblyV2.5-03.jpg?v=1781120786\" alt=\"\"\u003e\u003c\/p\u003e","brand":"ONYX Motors","offers":[{"title":"4T Rear Wheel Hub Motor Assembly 1.6\" x 17\"","offer_id":54363584856374,"sku":"RR-00002","price":671.99,"currency_code":"USD","in_stock":true},{"title":"3.5T Rear Wheel Hub Motor Assembly 2.5\"x 17\"","offer_id":54363584889142,"sku":"RR-B0002","price":751.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/4182\/9430\/files\/ONYXRCR72V-RearWheelHubMotorAssemblyV2.5-01.jpg?v=1785763877","url":"https:\/\/enclothin.com\/products\/rear-wheel-assembly","provider":"enclothin","version":"1.0","type":"link"}
