Pantera e-bike feature Schrader valves (also called American valves). In this kind of valve the main stem is externally
wrapped in a threaded pipe. To press the central core, you need such a thin tool as a pen cap or a fingernail.
Unscrew the rubber cap on the top of the valve (protection) and lay it caring not to lose it.
The tyres pressure affects the bike manoeuvrability and saddle comfort. A higher pressure lowers rolling
resistance and perfectly conforms to smooth and dry surfaces. A lower pressure, on the contrary, allows a
smooth driving and increases grip, so it conforms to bumpy roads or to rough and slippery surfaces.
For transport purposes, your e-bike tyres are only partially inflated.
To release the regulator, lift the stick and quickly screw the cap on the valve.
The recommended pressure value is 20-25 PSI (1,3-1,7 bar). Monitor the pressure gauge while inflating the tyre. The
ideal tyre pressure depends on the rider weight and on the type of terrain.
After installing the front wheel, proceed to inflate the tyres. First of all, place the e-bike on the wheels.
Connect the pump to the valve. In case there is a stick close to the regulator, check it is open (parallel to the nozzle).
Close the stick by snapping it downwards (so that it is perpendicular to the nozzle).
To deflate an air chamber Schrader valve you can simply press the inner stem with a fingernail or a thin tool to let all
the air out.
Never inflate the tyres above 35 PSI (2,4 bar). The air chamber might burst in case of overpressure.
A correct tyre pressure preserves the rims, the air chambers and the tyre themselves from possible damages.
Furthermore, a perfectly inflated tyre extends the life and duration of the battery.
