E-Substance Aluminium Apex (Fazua)
Vitus
Gravel
E-Substance Aluminium Apex (Fazua) is an alloy electric gravel road bike (2024), by Vitus. It is a strong match for a wide range of riders thanks to its fit flexibility, with a setup that gives you a balanced riding position, while being ready for gravel routes as well as pavement. Based on the metrics, key strengths are good fit flexibility for dialing in rider position, a balanced ride feel between comfort and directness, and all-round climbing capability rather than a narrow specialty. The trade-off to keep in mind is less emphasis on outright speed than speed-focused builds and battery range that is better for shorter daily use than long all-day outings.
