Motors & Controllers
Hub & mid-drive · 250W–3000W · sine wave FOC controllers · IP54–IP65
Motor & Controller Parameters
Our motor and controller systems are designed as matched pairs for optimal efficiency. Each combination is dyno-tested at five load points before shipping, with a test report included in every production batch.
The 60-second read for buyers: as an OEM line item or aftermarket range, this motor and controller family covers 250 to 1500 W geared hub, direct-drive and mid-drive units at 36-72V, with FOC sine-wave controllers, regenerative braking, CAN/Bluetooth telemetry, IP65 motor winding and IP54-65 potted controllers - matched to hub, mid-drive and throttle specs for each vehicle. Orders start at 50 units per configuration with a 15-30 day standard lead time (30-45 days for the first custom-branded run), and pre-production samples ship before mass production. The compliance package and per-order documents (cell, BMS and test reports where applicable) are compiled with the export file, and an export engineer settles fitment questions on one call — no obligation.

OEM Options
Motors and controllers are the heart of the electric drivetrain. We support deep customization from winding specification to controller firmware — every variable is tunable for your specific vehicle platform and rider profile.
- Motor winding spec (KV rating for speed vs torque)
- Cable exit position (axle side)
- Connector type (custom L1019 / Julet / waterproof)
- Magnet grade (N35–N40SH)
- Controller programming (acceleration curve, regen strength, speed limit)
- Display pairing (matching LCD / TFT)
- Branding on motor side cover (laser engrave / silkscreen)
- Cassette vs freewheel freehub
- Disc brake mount (ISO 6-bolt / centerlock)
- Axle standard (M12 / M14 with flat)
Certifications
Motor and controller assemblies are tested to relevant electromagnetic compatibility and safety standards. For complete vehicle certification, the motor-controller pair is submitted as part of the EN 15194 system-level test package.
