TORP has officially discontinued the TM50 motor to focus to the next generation lineup: the TM50 Pro and the all-new TM50 Speed.
Torp TM50 motor has been meticulously designed by expert engineers with top-quality components for exceptional speed and heat efficiency on even the most challenging terrain, with up to 58kW of power output (TM50 Pro).
TM50 Speed vs TM50 Pro
Both Torp motors are built for the Ultra Bee — but tuned for different riding styles.
TM50 Speed Motor
- Built for high-RPM operation
- Higher KV for greater top speed
- Performs well on 72V setups but 80V is recommended
- Ideal for road riders wanting higher top speed
TM50 Pro Motor
- Optimized for off-road torque
- Stronger in the low-to-mid RPM range
- Best paired with 80v battery systems for full potential
If you want strong off-road torque with stronger low-to-mid RPMs, the TM50 Pro is the right choice.
If you want maximum speed and high-RPM performance, the TM50 Speed is best.
Compatible with the Torp TC1000 controller
