What this bill would change
The enacted Colorado summary says the law requires seller disclosures, requires new e-bikes to be labeled with the highest class or classes they are capable of operating in starting January 1, 2027, requires qualifying lithium-ion battery certification, and treats false e-bike labeling or marketing as a deceptive trade practice. It also clarifies that easily configurable vehicles that do not meet an e-bike class are not electrical assisted bicycles.
Who it affects
Colorado retailers, buyers comparing moped-style bikes with true e-bikes, and families who want clearer sales-floor information before purchase.
Parent takeaway
This law matters to families because it targets the sales-side confusion. It gives parents a stronger basis to ask whether a fast or modded machine is being sold as something it is not.
Buyer takeaway
A Colorado buyer should expect clearer class and battery disclosures over time, but still needs to open the state law page for trail rules because this bill is mainly about what can be sold as an e-bike.
