Usually, we are not covering eBikes, but the Trek eCaliber is something a little different. The eMTB has come a long way in the last few years. Many of the models we’ve seen are geared to the bike park or more aggressive trail riding, but Trek’s new eCaliber is a bit of a different take. Aimed more at the distance chasing, marathon cross-country crowd, the E-Caliber aims to give the long-distance ‘XC’ style rider a little more gas in the tank on those epic rides. It would also make a pretty nice full suspension gravel bike as well.

The E-Caliber looks quite similar to Trek’s XC race bike, the Supercaliber, except with a larger downtube where the battery and Fazua Evation drive system lives, but there are a number of other differences between the two.
Trek E-Caliber Details
While the E-Caliber uses the same IsoStrut suspension system and 60mm of travel that the Supercaliber does, it has a 120mm fork, and a slacker 67.5-degree headtube angle. The reach is also between 10-15mm longer depending on the frame size for increased stability at speed.
The E-Caliber is designed to fit somewhere in the middle of the gap from standard non-pedal assist bike to eMTB. It’s not a full-throttle with minimal effort style of ride, and riders will still need to have some fitness. Trek calls it more of an equalizer for riders who may want a little extra assist, for instance, you’re trying to keep up with your World Cup level friend on their recovery day without it feeling like a World Cup race to you.


The wow factor on this e-MTB is that Trek E-Caliber has the ability to become a normal bike if the battery is removed. That’s right, the Fazua system integrated with the down tube can be completely removed and a hollow storage system can be put in its place without breaking the aesthetics of the bike. In the case of the top-of-the-range E-Caliber 9.9 XX1 AXS, it weighs just 12.87 kg.
