FAQs
Q: Why does the controller say 48V when the GT50 has a 60V battery?
A: The “48V” marking is a standard label on the controller housing. Internally, the GT50 uses a wide-voltage smart ECU system that supports 48V–60V input, so it is fully compatible with the included 60V 30Ah battery.
Q: Why does the tire show 16 instead of 20?
A: The “16” on the tire sidewall refers to motorcycle-style rim diameter, while the product page lists the tire’s approximate outer size as 20" x 3.0". These are two different tire measurement standards.
Q: Are the GT50 tires suitable for off-road riding?
A: Yes. The GT50 uses wide 20" x 3.0" motorcycle-style off-road tires with aggressive tread, suitable for gravel, dirt trails, mountain roads, rural roads, mud, snow, and pavement.

A: The GT50 can reach up to 40 MPH under suitable conditions. Actual speed may vary depending on rider weight, terrain, battery level, tire pressure, and riding mode.
Q: How far can the GT50 go on one charge?
A: The GT50 offers up to 80 miles of range. Actual range depends on speed, rider weight, road conditions, throttle usage, assist level, and weather.
Q: How long does it take to charge the GT50?
A: The GT50 battery usually takes around 6–8 hours to fully charge.
