Baserunner for Brompton Bike Conversion

More Views


The Baserunner is a compact field-oriented motor controller originally designed to fit inside battery downtubes. This version is configured for Brompton installations or other motors where the white signal wire is used for the motor thermistor instead of a motor speed signal. The motor hall signal is then passed to the CA plug for the speedometer sensing.

It is compatible with up to 14s (58V) battery packs and is terminated with a Z910 waterproof HiGo motor plug. Cables and connectors are otherwise identical to the Phaserunner, and remote on/off switch wires are present under the throttle heatshrink. Requires PC setup to mate and configure with a given motor, and this requires the USB->TTL communications cable if you don't already have that. Users without an on-off switch on their battery should expect to wire in a separate switch on their own. Full Phaserunner Information Page.
