KIT-SX2_Bare
The mid-sized and silent SX2 geared hub motor is an awesome all-around choice for many ebike applications, and freewheels for zero additional wheel drag when pedaling unassisted. If a downtube battery pack is selected, we will mount the baserunner controller inside the battery cradle for a very clean install.
The barebones system uses a throttle with an integrated on/off switch and voltage readout, but doesn't have a fully featured display or options for PAS / Torque sensors. This makes it great for simple and clean ebike builds that want to avoid any additional complexity.
The throttle also includes two extra wires for running a front bike light and hooking up an optional ebrake cutoff sensor.
For a full explanation of the various drop-down choices and a comparison of this package versus other motor options, see our Grin Kits Info Page
