Why ride with VortexCycles

Buying an e-bike online takes trust. Here's exactly what you get when you buy from us.

Authorized dealer for Revi Bikes, EUNORAU, Rattan, HappyRun, and Yamee. Every bike is new, factory-sealed, and backed by the full manufacturer warranty.

Coverage, spelled out. Manufacturer warranties run 12 to 24 months depending on the brand, with EUNORAU frames covered for 10 years. They cover manufacturing defects, not wear parts like tires, brake pads, and chains. Each bike's exact coverage is listed on its page, and optional Product Protection adds accidental-damage coverage.

Help from start to finish. Get straight answers on fit, power, and setup before you order, and support with warranty claims after it arrives.

Ships free from a U.S. warehouse. Most bikes arrive in 7–10 business days by FedEx or UPS to the lower 48. Tracking is emailed as soon as your bike ships, and a signature is required on delivery.

The two minutes that protect your purchase. Before you sign, walk around the box. If it's torn, crushed, or punctured, write it on the delivery slip and photograph it before you open it. A clean signature makes a damage claim much harder to win. Some brands require damage reports right away, so open the box the day it arrives. We'll work the claim with you.

14-day returns. Start a return within 14 days of delivery. See full return terms.

Pay over time. Shop Pay Installments shows your options at checkout, and checking won't affect your credit.

Secure checkout. Payments run through Shopify's encrypted checkout, and we never see or store your full card number.
