The ETM 2.0 is a motor and controller kit that replaces the stock drivetrain on several small electric dirt bikes, including Mototec, Funbikes MXR, Stomp EBOX, GPX E-48R and Apollo RXF Rocket models. It pairs a new IPM V-magnet brushless motor with an FOC controller for more low-end torque and higher top speed than stock. Output scales with the battery you already run: about 3600W on 48V, 4650W on 60V and 5700W with the optional 72V Mighty Mini pack. It suits owners of these bikes who want trail-ready power without buying a new machine; the trade-off is that it is a parts kit, not a complete bike, and the biggest gains depend on a battery upgrade.

The ETM 2.0 Drivetrain Upgrade Kit replaces the drivetrain electronics on select electric dirt bikes. It is built around an IPM V-Magnet brushless motor and an FOC controller. The kit increases low-end torque and top speed over stock.
The motor can exceed 8500 RPM at the shaft and is designed to run at lower temperatures. A handlebar-mounted MX-style twist throttle with a 3-position power selector switches between three power modes.
Output depends on the battery: 3600W with a stock 48V battery, 4650W with a stock 60V battery, and 5700W with the optional Mighty Mini 72V battery. A 48V to 72V lithium battery is required to run the kit. It does not fit ETM v2 or BombMoto bikes.
