⚡ At a Glance
- • Power Delivery: 72V rated system with 3,000W continuous output, rated speed 4,900 rpm and no-load up to 6,700 rpm
- • Best for: DIY go-kart and e-scooter builders, Razor MX650 upgraders and light e-bike conversions
- • Not ideal for: Full-sized motorcycles or heavy commercial EV conversions that require sustained higher continuous power
A 72V, 3,000W brushless motor kit with temperature sensing, waterproof cables and an included sprocket. Suited to hobbyist upgrades on scooters, go-karts and light electric bikes.
Overheat protection - thanks to KTY83-120 temperature sensor
KTY83-120 temperature sensor mounts to the motor and sends temperature data via the 6-pin waterproof cable to compatible controllers, which can be set with threshold values. This allows the controller to throttle or cut power when temperatures rise.
Temperature-based cut-off or throttling prevents thermal damage during heavy current draw, extending motor life and reducing failure risk.
Safer, smoother control - with upgraded controller protections
Controller firmware includes overload, undervoltage and short-circuit protections, and supports speed control, braking, reverse and slow-start functions for controlled acceleration. These protections monitor electrical conditions and intervene when parameters exceed set limits.
Predictable starts, reliable braking and protection against electrical faults make rides safer and reduce the chance of component damage.
Easier fitting and compatibility - with 6mm² phase wires and included sprocket
Supplied 6mm² phase wiring, 6-pin waterproof car-style cables and a 25H/T8F 11T sprocket chain wheel simplify mechanical and electrical connections. A half-twist throttle with digital display aids setup by reporting battery level and distance.
Straightforward wiring and included mechanical parts speed up installation for common mini vehicles and popular Razor upgrades.
