Is the crack on the bike wheel rim caused by damage?
No, actually. Many big-brand wheel rims have a manufacturing seam—heated, bent, then joined into a circle. It’s a normal craft mark, not damage.
Is it normal for the charger and battery to get warm during charging?
Yes, nomal. This bike’s 3A fast charging sends more current quickly, causing warmth. Safe if under 130°F.
Why might my e-bike lose power or stop under heavy loads, long climbs, or heat?
2 main reasons: motor overheating (controller cuts/reduces power to prevent damage) and controller overheating protection (limits power or shuts down).
