Always ensure the key is in the off position when unplugging or plugging in any electrical
components.
How the throttle works
The throttle is located on the right side of the handlebar. The rider can use it with a twist of
the throttle grip to propel the bike forward without pedaling. To engage the throttle while
riding, slowly and carefully rotate it toward yourself. The more you twist, the more powerfully
the throttle will propel the bike forward. Once you release the throttle or apply the brakes,
the throttle will no longer propel the bike forward. Always keep one hand on the brake lever
and be prepared to squeeze the lever if needed. Thumb throttles from Bowhead are equipped
with an on/off switch for the throttle.
The throttle displays battery life in voltage (V) NOT percentage. This display will never
reach 0V. It is strongly recommended that riders head back to a charging zone once the
throttle display reads 72V.
How the charger works
Charging the battery should be at room temperature (±20°C/68°F). Charging below 0°C or
above 40°C (32°F~104 °F) can lead to insufficient charging and can be harmful to the
battery life cycle.
You should always remove your battery from your bike prior to charging.
