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.

Why choose an electric mountain bike like the Thunder over a regular MTB?

Lacros Thunder gives you the thrill of mountain biking without the strain. The electric assist lets you power up hills and go further without burning out, making it ideal for longer or more challenging rides.

How does Thunder perform compared to other mountain electric bicycles?

Thunder stands out with its full suspension system, powerful battery, and rugged build and also price. It’s not just about power—it’s about stability, comfort, and pushing the limits on and off the trail.

Can I use Lacros Thunder for daily rides as well as mountain adventures?

Yes! While it's made for the outdoors, Thunder’s comfortable ride and durable design also make it a solid choice for everyday use. It's a versatile mountain electric bicycle that adapts to any road you choose.
