When will I receive my electric bike?
Ship from California or Pennsylvania warehouse. Processing (1–2 business days); Deliveries within the shipping state typically take 2–3 business days, while deliveries to the lower 48 states (excluding the shipping state) usually take 4–7 business days.
Will the ebike I received be assembled?
The bike will arrive mostly assembled. We provided the tools in the box and an assembly video on the detail page.
How to Activate Dual Motor Mode?
To activate the dual motor system, please press the red button on the left handlebar.
What kind of battery does this eBike have, and how far can it go on a single charge?
This eBike is equipped with a high-capacity 52V 25Ah lithium battery, offering a range of 40–60 miles on throttle mode and 50–100 miles with pedal assist.
How to turn on the electric bike?
Press the battery power button to the 丨 position, then hold the middle power button for 3 seconds to turn on the display. PAS-0 is the pedal mode; PAS 1-5 are the power assist modes.
How to activate the bicycle boost mode?
Holding the "-" button will activate the boost mode.
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).
