Every review, buyer's guide, and news story on this site carries Sean's byline because he's the one accountable for it. Before starting ElectricBikes.com he spent more than a decade running two American e-bike companies — building, selling, servicing, and warranting the exact category of product reviewed here.

Why this byline is worth trusting
40+ years of combined operating experience
Sean and his partners ran two of America's most important electric bike companies for over a decade — on opposite ends of California, in opposite corners of the market. One grew into the largest e-bike-only dealer network in America and sold in a nine-figure transaction; the other hand-assembled cruiser e-bikes one at a time in Southern California, owning production from raw frame to a road-tested bike delivered fully assembled.
75,000+ e-bikes designed, built, and delivered
That means building bikes by hand, qualifying overseas suppliers, auditing factories, training service technicians, standing up dealer networks across all 50 states — and personally signing off on warranty claims for failure modes most reviewers have never seen.
Battery safety, hands on
Sean has overseen battery safety testing and certification work (UL 2271 / UL 2849), cracked open battery packs, and administered the warranty claims that follow when a cell or BMS goes wrong. When a review here flags a battery concern, it comes from that experience — not from a spec sheet.
