Fezzari Bicycles (United States) - Press Release: Wire Peak. Explore more.

See more trails and take longer rides. The Wire Peak was built for performance and handling first, and pedal assist second.

Bike First - A world-class mountain bike that happens to have power.

Handling:

We designed the motor system around a top performing bike. That means it first has to have the right geometry (short chainstays, slack head angle, steep seat tube, 27.5+ and 29 wheel compatibility) to make it a world-class bike with the added benefit of pedal-assist.

Performance:

Explore new trails with confidence. The 140mm Tetra-Link suspension soaks up small bump chatter with a bottomless feel on rocky descents, and an efficient pedal platform for responsive climbing. Forward-thinking geometry makes the Wire Peak lively in corners, light for manuals and jumps, and inspires confidence downhill. Add pedal assist to go farther and climb what was once impossible.

Do More - Climb steeper, pedal faster, go farther.

Climbing:

The Wire Peak gives you the pedaling platform and power to confidently go where you’ve never been before. Our refined TetraLink™ design caters to the demands of pedal-assist riding. And the steep seat tube angle provides efficient pedaling while maintaining a supple ride.

Range/Modes:

Longer Rides = More Fun. With our custom 504 Wh battery you can go farther with a range of up to 60 miles. 3 power levels - Eco, Trail, and Boost - allow you to choose the optimal power output during your ride. Choose your own adventure and get the perfect assist level for your workout.

Technology - Making the Wire Peak:

Bike First:

To make the Wire Peak’s performance and handling world class, we started with suspension design and geometry. Then we integrated power assist. Motor positioning, pivot locations, and responsive TetraLink™ suspension make it one of the funnest bikes to ride with or without power.

Geometry:

Most design a bike around the motor system. We designed the motor system around the bike. For example, we had to change the orientation of the motor to keep the chain-stays short for better performance and handling.

Battery Shape & Seal:

Our battery’s sleek profile and cover give the Wire Peak a slim look without compromising range. Ride up to 60 miles on a single charge.

Sound:

The motor system design, the two stage battery locking mechanism, silent cable routing, and frame design reduce bike noises so you hear less of the bike and more of nature.

Battery Removal & Security:

The battery locks securely in the Wire Peak. It’s easily removable for on-bike or off-bike charging (with optional plug), battery swapping, cold weather charging and storage.
