Lacros Ebikes FAQs

Do I need a license to ride an ebike on the road?

No. Our ebikes are under US regulations and laws that enable you to ride them without a specific license.

How long will it take to receive my ebike?

In-stock products usually will be shipped in 1-3 business days unless special information is noted on the product page. Delivery time generally takes around 3-7 business days, which depends on where you live. You will receive a shipping confirmation email after the order ships out, including the shipped item, tracking number, shipping carrier, and shipping address.

How long does it take to charge the battery?

Charging the battery from empty to full usually takes 8 hours for Lacros Thunder and Lacros Cyclone, and 6 hours for Lacros Pinecone.

In rare cases, it may take longer, especially when the bike is new or after extended storage, to allow the battery management system to balance the battery.

I have more questions.

There are more answers and solutions in the FAQs page. Or you can send an email to customer@lacrosebike.com.
