DO THE KITS WORK ON ANY BIKE?
Most bikes with open‑slotted dropouts and quick‑release wheels will work. Check dropout width and make sure your frame has space for the battery.

WHAT ARE DROPOUTS AND HOW DO I MEASURE THEM?
Dropouts are the slots where your wheel axle sits. Measure the inside width — usually 135 mm for most quick‑release bikes. Match this to the option shown on the product page.

WHAT COUNTRIES DO YOU SHIP TO?
We ship to Australia, USA, UK, Canada, France, Poland, Austria, Greece, Croatia, Spain, Italy, Hungary, Bulgaria, Germany, Belgium, Portugal, Slovenia, Slovakia, and the Netherlands.

HOW FAST WILL MY E‑BIKE GO?
Check the product page for your kit’s top speed. Actual speed can vary with rider weight, terrain, and battery choice.

WHAT’S THE DIFFERENCE BETWEEN SINE WAVE AND SQUARE WAVE CONTROLLERS?
Sine wave: smoother, quieter, better control.
Square wave: more punch off the line, a bit louder.

ARE THE KITS WATERPROOF?
Motors and controllers can handle rain and wet riding conditions. Avoid fully submerging parts or pressure‑washing.

DO THE MOTOR AND BATTERY SHIP TOGETHER?
No – they’re shipped separately due to size and shipping rules. You’ll receive tracking for each.

HOW LONG WILL DELIVERY TAKE?
Express: 2–4 weeks.
Standard: 40–70 days.
Production time is usually 5–10 business days.
