As innovation continues to drive the recumbent world, electric assist recumbents are in higher demand than ever before. Falco E-Motors is one of the most popular and reliable hub-motor systems on the market today and their patented 5-phase technology is a powerful option for KMX Karts. Choose between the 500W motor and 36V battery, or the 750W motor and 48V battery.

The Ecospeed motor transforms your recumbent trike into an ultra-efficient electric vehicle. Top speed is 20 mph without pedaling and over 30 mph with. The basic battery pack will give you 40-60 miles of range and you can add more batteries if you want to go farther. The chain-drive system allows the motor to use the gears, a huge advantage over hub-drive motors.
