"As expected, the E-Caliber made us feel like the World Cup racers we wish we were, but the real benefit was that we were more willing to ride, rather than drive, to our favorite trails. Logging more miles in the same amount of time is a win in our book."
Read more"The combination of short travel, light weight, and aggressive geometry will make for a bike that opens up the joys of long trail adventures and ripping fast singletrack to a segment of riders that may not otherwise get to experience that thrill."

Watch the videoFast and efficient
Fazua's lightweight drive system adds a punch of power when you need it, but rides and feels like a traditional bike when you don't. You won't feel much drag or resistance when you turn it off or pass the max level of assist. The system is also compatible with a smartphone app to let you check battery status and customize your ride.
Smart software for the trail
E-Caliber is equipped with intelligent Fazua software called BLACK PEPPER, which allows the motor to respond immediately as you start to pedal, delivers more power over a wider cadence range, and lets you customize your user settings.
Removable drivepack
Remove the motor and drivepack to save 6.4 lbs./2.9 kg on days when you don't need the boost. The included cover also turns the down tube into extra storage.
E-Caliber has the same innovative IsoStrut rear suspension as World Cup-winning Supercaliber. You get 60mm of integrated rear travel—just the right amount of comfort and traction, without the weight or flex of traditional full suspension.
Trek's mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Trek's advanced engineering, and a higher standard of testing.
Compliant with leading safety regulations
The e-systems on Trek and Electra e-bikes are third-party tested to meet the latest e-bike safety regulations, including the stringent UL 2849 certification — so all you have to worry about is where your e-bike will take you next.
This suspension calculator will help you optimize your suspension settings for your riding weight. Simply follow the steps to find your best set up.
Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right out of the box with the included TLR rim strips, valves, and sealant.
Every set of Bontrager carbon wheels is backed by the Carbon Care Wheel Loyalty Program. In the unlikely event that you damage your Bontrager carbon wheels within the first two years of ownership, we’ll repair or replace them for free.
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked, and your controls won't hit the top tube.
With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
