Our most common controller form factor: a rectangular aluminum box housing sine-wave FOC
controllers for 24V/36V hub-motor e-bikes at 250-350W. Twenty dimension variants cover the
mounting footprints used across common frame and downtube layouts.
These are wholesale, quote-only parts. Tell us your motor’s rated power, voltage and Hall/Hall-less
sensor type and we’ll confirm the matching controller model and pricing.

Highlights
- Ultra-quiet: torque ripple minimized for noise- and vibration-free riding.
- Higher efficiency: FOC (field-oriented control) reduces controller heat and extends battery range.
- Multi-layer protection: over-current, over/under-voltage, over-temperature, runaway, short-circuit, phase-loss and stall protection.
- Auto-sleep: cuts power automatically after 10 minutes idle to save battery charge.
- Flexible configuration: current limit, undervoltage cutoff, sensor type, top speed and assist ratio adjustable via USB or display.
- EN15194 tested: 100% pass rate on all specifications and functions.
