The LeMond Prolog weighs just 26lb. It is one of the lightest e-bikes on the market.
Buyers can choose between three sizes and three matte color finishes.
Experts say riding the Prolog feels just like riding a traditional bike, and it's a joy to pedal without assistance.
Testers appreciate the smooth shifting and ample gearing of the 11-speed Shimano GRX drivetrain.
The Prolog arrives tuned and almost fully assembled. Reviewers say it's the best packaging they've seen in terms of protection, ease of opening, and clear instructions.
Testers say LeMond's stated range of around 40 miles is accurate.
According to one expert, the Prolog can handle light single-track, dirt, and gravel.
The Panaracer GravelKing 38mm tires are tubeless-ready.
Experts and owners agree that the Prolog is beautifully designed and doesn't look like an e-bike.
Reviewers say the Prolog feels stable, responsive, and nimble.
Experts note that the Selle Royal saddle is comfortable with or without padded shorts.
Tests show that the Shimano hydraulic disc brakes provide plenty of stopping power.

8 reasons not to buy

Reviewers agree that the Prolog is expensive for a commuter-style bike. Some mention that they wouldn't feel comfortable locking it outside.
This e-bike doesn't have a display, so monitoring pedal assist and battery levels isn't intuitive.
One expert says the placement of the iWoc control button on the top tube is less safe than handlebar-mounted controls.
A reviewer feels that, without a rack or basket, the Prolog lacks utility as an urban e-bike.
Several testers say the MAHLE X35 motor isn't very powerful.
The battery isn't removable, so charging the Prolog may be inconvenient.
The integrated stem and handlebars aren't adjustable, and one expert complains that the handlebar on the large model is too wide.
The road bike-style geometry may be too aggressive for the average e-bike rider.

Bottom line

The LeMond Prolog is a flat-bar, all-road electric bike. Stunning aesthetics and an exceptionally low weight distinguish it from the competition. However, these characteristics result in a few notable compromises. The Prolog has sporty geometry and ride characteristics, subtle power, and a high-end carbon fiber frame. These features and its limited utility mean it likely won't suit the needs or budget of most urban riders. Nonetheless, experts agree that the Prolog earns its hefty price tag for those passionate cyclists who want an extra boost without eliminating the workout.

Review: LeMond Prolog

Level 1 expert

At this price, this bike is a pretty hard sell under any circumstances… There is, however, one very good reason to buy this bike, and that’s if it makes your heart sing. The Prolog does this to every bike person I know, including me.

LeMond Prolog Review: The Urban E-Bike That Doesn’t Look Like an Electric Bike

Level 5 expert

It’s a sleek, stealthy bike that also offers a playful, nimble ride. It can serve as a high-end commuter or a lightweight, capable hybrid… But it lacks in utility and comes with a lofty price tag.

The LeMond Prolog E-Bike Review: There’s Lots to Talk About

Level 5 expert

The Prolog is a simple bike that’s easy to use and helps you on your way. Fenders as intentional, not an afterthought. Front and rear lights always ready. Something to talk about over a cortado. Lots to talk about, really.
