Features. Good heat dissipation. The
controller shell is made of aluminum alloy, which can protect the
internal circuit, facilitate heat dissipation, avoid thermal overload,
and is durable. Stable speed and sensitive control. The
electric bike controller is a brushless motor controller, which can
provide stable speed, silent operation, sensitive control of braking and
direction changes. Automatic recognition of Hall sensors. It
can automatically identify the phase angle and rated voltage of the
electric bicycle, and protect against inertia and reverse current,
making it more efficient and energy-saving. Easy to install. Each
interface has a different color, which is easy to install. The wire and
interface are durable and ensure low failure rate for long-term use. Application. The brushless motor controller is highly suitable for electric bicycles, electric tricycles,etc. Specifications.
