Wire Peak 2.0 Comp
The Ari Wire Peak is a value-oriented, full-suspension electric mountain bike designed for trail riding. Formerly sold under the Fezzari name, this aluminum e-MTB pairs 145mm of rear suspension with either a 150mm or 160mm fork, depending on the build. It is positioned as an accessible entry point into powered riding, offering a modern chassis without the premium price tag of boutique alternatives.
Tipping the scales around 55 pounds, it is a heavy machine that relies on motor assistance to mask its mass on the ascents. On the trail, the Wire Peak favors flowy, high-speed terrain over tight, technical maneuvers. It suits newer mountain bikers looking for a stable, predictable platform, as well as budget-conscious riders willing to accept entry-level components in exchange for a highly capable frame.

Fit and geometry
The Wire Peak features modern trail geometry that often measures more aggressively than the manufacturer’s official charts suggest. Independent testing reveals a slack head tube angle hovering around 64 to 64.5 degrees, which pushes the front wheel out to create a stable platform for descending. To balance this long front center, Ari utilizes remarkably short 434mm chainstays. This compact rear end helps riders lift the front wheel and pivot the heavy frame through corners with less effort than the wheelbase might imply.
Seated pedaling posture is defined by an exceptionally steep effective seat tube angle, measured by testers at nearly 79 degrees. This places the rider in a forward, upright position directly over the bottom bracket. This steep angle is highly efficient for keeping the front wheel weighted and tracking straight on steep ascents, neutralizing the tendency of the short chainstays to loop out under motor torque. The reach is generous, providing ample room in the cockpit, though the steep seat angle ensures the rider never feels overly stretched out while climbing.

Builds
The Wire Peak lineup is split across three tiers—Comp, Elite, and Pro—all utilizing the same aluminum frame but featuring distinct motor and suspension packages. The entry-level Comp build is equipped with a Shimano E7000 motor producing 60Nm of torque, paired with a RockShox Recon Silver RL fork. While this configuration keeps the price exceptionally low, the 32mm fork stanchions and modest motor output are noticeable limitations for aggressive riding.
Stepping up to the Elite and Pro models materially changes the bike's capability. These higher tiers upgrade to Shimano’s EP800 and EP6 motors, respectively, boosting torque to 85Nm for much stronger climbing assistance. They also feature stiffer, longer-travel forks—a 160mm DVO Diamond E3 on the Elite and a Fox Float 36 on the Pro—which better support the bike's weight during hard descending.
All builds include 4-piston brakes with 200mm or 203mm rotors, a crucial inclusion for managing the bike's momentum. Because the frame is identical across the range, the Comp serves as an affordable, upgradeable platform, while the Elite and Pro offer a more robust, trail-ready specification straight out of the box.
Reviews
Reviewers consistently note that the Wire Peak exhibits a dual personality on the trail, heavily influenced by its substantial mass. At higher velocities, the bike feels stable and composed, with testers observing that it "rips corners and holds its momentum well" (Outdoorgearlab). However, when navigating tight switchbacks or slow technical sections, the steering becomes noticeably sluggish, requiring deliberate physical input to muscle the front end through unintended lines.
While the rear suspension does an adequate job of muting trail chatter, the front end of the entry-level model drew significant criticism. Testers found the 32mm stanchions on the base fork to be "under-gunned" (Outdoorgearlab) for a 55-pound e-bike, leading to a hesitant feel on aggressive descents. Despite these component limitations, the underlying frame is praised for its predictable handling.
Ultimately, the bike is viewed as an excellent starting point for riders transitioning to electric mountain bikes. One reviewer highlighted it as a "super fun bike and a good way to get into the sport" (YouTube), especially for those who want to avoid grueling analog climbs. The consensus points to a capable chassis that rewards flowy riding, even if the stock suspension on lower tiers limits its ceiling in steep, rough terrain.
