TREK E-Caliber 9.9 XX1 AXS Gen 1 2021
The E-Caliber 9.9 XX1 AXS carbon e-MTB is lightweight, exciting, and quick to ride. It’s built to handle like a classic XC bike, and it uses the same race-ready suspension technology as the Supercaliber. The Fazua drive system is an elegant and unobtrusive way to gain power without increasing overall size, and it comes with a generous assortment of top-tier hardware.
If you’re looking for a lightweight e-MTB that can rip singletrack like a conventional XC bike, but also provide a little boost when you need it, then this is the one for you. You’re also looking for a fantastic component list, loaded with carbon and wireless technologies like our IsoStrut shock and a completely wire-free electronic powertrain.
This cool new tech
It features Trek’s exclusive lightweight IsoStrut FOX Factory shock, a 120mm RockShox SID Ultimate fork with Charger Race Day damper, remote lockout, and 120mm of travel, and a full OCLV Mountain Carbon frame that’s incredibly light and lightweight. Included in this package is a Fazua eVent motor and 250Wh battery that, when engaged, may provide assistance at speeds of up to 20 mph and, when disengaged, create no additional resistance, as well as a Fazua Remote FX controller that can be put on the handlebars. Bontrager XXX Carbon Seatpost, Kovee XXX 30 carbon wheels, and an SRAM XX1 Eagle AXS wireless electronic drivetrain.
Finally, the last word
Premium grade E-Caliber from us is quick, agile, and built to shred. It handles like a cross-country race bike—a Supercaliber, in fact—until you need that extra boost to scramble up a rise or throw in some extra laps.
What makes it so great:
Intelligent, silky, and wireless, the SRAM XX1 Eagle AXS drivetrain. The motor provides assistance on hills and lengthy rides, but it’s a more subtle boost that feels more like riding a regular bike than an e-MTB.
The motor and driving system can be detached quickly and easily. After removing it and covering it with the provided cover, the weight of your regular mountain bike will drop by 2.9 kg.
IsoStrut provides optimal rear suspension for efficient, lightweight, and comfortable cross-country riding;
