Titanium eBike Crankset - For Bosch / TQ / 2025 Specialized Levo

The 5Dev Titanium eBike Crankset is a purpose-built titanium eMTB crank upgrade designed for modern high-torque drive systems, combining low weight with the fatigue strength needed for repeated e-bike load cycles. Machined in San Diego from solid Ti-6Al-4V bar stock on 5-axis CNC equipment, it targets riders who want long-term durability, precise power transfer, and a clean fit on Bosch-, TQ-, and 2025 Specialized Levo-spec motor platforms using an ISIS spline interface.

What makes it a smart eMTB crank upgrade

1. Ti-6Al-4V e-bike durability - Built to resist fatigue under higher torque loads and repeated drive-assisted power inputs
2. Exceeds ISO Race standard - Designed to meet race-level durability expectations under e-bike stresses
3. ISIS splined interface - Intended for use with Bosch, TQ, and 2025 Specialized Levo motor systems that use an ISIS-compatible spindle
4. Low-profile crank arms - Helps reduce pedal strikes on technical climbs and rough trail features for more consistent momentum
5. Titanium ride feel - Titanium’s inherent damping can help take the edge off high-frequency trail buzz on long, fast eMTB rides
