Frame and installation checks
- Measure the rear dropout width and confirm axle fit before purchase.
- Check disc-brake rotor alignment, caliper clearance, and cable routing.
- Use suitable torque support on both sides where the frame and installation allow.
- Have the electrical system installed and inspected by someone familiar with high-power e-bike builds.
Battery matching
Compare the 72V 40Ah e-bike battery and the triangle battery options. Compatibility depends on controller voltage, discharge demand, connectors, available frame space, and the full build.
No specific speed is guaranteed. Final performance depends on the complete system, wheel size, load, terrain, installation, and local rules.
