Independent E-Bike Build Advisor for the US Market
EbikePartsPicker is an independent e-bike conversion advisor. We exist to solve a real problem: the e-bike conversion market is confusing, filled with incompatible parts, unclear legal requirements, and too many choices that lead to wrong purchases.
Our mission is to guide you through the conversion process with confidence. We help you understand what parts work together, what meets US federal and state regulations, and where to find trusted retailers.
We are an advisor, not a seller. We do not sell parts directly. We provide guidance and connect you with trusted US retailers.
At the heart of EbikePartsPicker is our Build Advisor — a guided, 6-step wizard that helps you make informed decisions about your e-bike conversion.
The Build Advisor asks about your riding needs, bike compatibility, physical requirements, experience level, and budget. Based on your answers, it provides personalized recommendations with budgetary targets — not firm prices, because prices change frequently.
E-bike regulations in the United States follow the federal 3-class system:
The federal power limit is 750W. Our Build Advisor includes compliance guidance to help you understand which class your build falls into and where you can legally ride.
Note: State and local laws vary. Always check your local regulations before riding.
We check voltage, connectors, wheel fit, and component matching.
We flag potential issues and provide clear warnings.
We recommend based on your needs, not sales quotas.
We curate retailers with good reputations and documentation.
