3 reasons not to buy

Experts agree that this is an expensive bike.
The LeMond All-Road Prolog is only available in three sizes, and the integrated cockpit isn’t adjustable.
Buyers that want a display must pay extra.

Bottom line

The carbon fiber All-Road Prolog is the drop-bar version of the original LeMond Prolog, a lightweight hub-drive e-bike with gravel-ready geometry. Experts highlight the smoothness of the drivetrain, assistance, and overall ride. They add that it feels like a regular bike when riding without assistance. The All-Road Prolog also earns praise for its “clean” integrated design, including a one-piece cockpit. As noted by experts, the downside of this cockpit is the lack of adjustability, compounded by the limited sizing options. Reviewers feel the "expensive" All-Road Prolog's high price is justified for the e-curious road or gravel cyclist with a big budget.
