The Mach 4 SL is XC, distilled to its fastest form—engineered for efficiency, sharpened for precision and built to master the modern racecourse. Born from the crucible of World Cup XC and epic endurance racing, it balances a feathery build with an obsession for stiffness, control and efficiency. This is Pivot’s sharpest tool for riders who live in the red zone, engineered to crush climbs and meet the intense demands of real trails where races are actually won.

The Mach 4 SL carries the legacy of Pivot's very first bike, the Mach 4 Alloy, introduced in 2007. That original design set the foundation for Pivot's obsession with efficiency, suspension performance and race-bred handling. Since its debut in 2019, the Mach 4 SL has defined what a modern XC bike can be: lightweight, capable and relentlessly fast. Each generation refines that vision, evolving with the demands of today's courses while staying true to the speed and precision that started it all.

FEATURES:

  • Proprietary Ride Tuning Approach: At Pivot, every frame size is engineered independently through detailed strength-to-weight analysis and custom carbon layups. This process ensures that a size small rides with the same balance and performance as an XL, no shortcuts. By tuning stiffness and compliance uniquely for each frame, every rider gets the same confident handling, efficiency, and responsiveness, regardless of size. This approach is what allows the Mach 4 SL to feel so dialed, no matter who’s riding it. The Mach 4 SL also has the highest stiffness to weight ratio of any bike in our lineup because every gram matters and maximizing every watt of energy is critical.

  • Why dw-link?: dw-link is more than a suspension design; it’s the foundation of every Pivot. By combining precise anti-squat with exceptional small-bump sensitivity, it delivers a ride that pedals efficiently while staying planted and predictable. On the Mach 4 SL, that balance means every watt of your effort translates directly to forward momentum, with traction locked in across roots, rocks and technical climbs. The result is efficiency on the ups, composure in the corners and suspension performance that works with you on every section of trail.

  • Adjustable Travel: With our XC adapted travel-adjustable flip-chip you can choose between two rear travel options: 110mm and 120mm. The XC adapted travel-adjustable flip-chip lets riders fine-tune the Mach 4 SL’s rear travel for their terrain and riding style.

  • In-Frame Storage: The Pivot Toolshed™ in-frame storage system keeps your essentials securely tucked away, reducing clutter and providing quick, easy access for all your trail adventures, from short rides to longer excursions. The Toolshed™ includes two Toolshed™ bags, designed to carry a spare inner tube, essential tools and even a bit of extra space for a snack. An integrated magnet on the inside of the door holds quick links for fast and easy access.

  • Ultra-Clean Cockpit and Cable Routing: The Mach 4 SL’s cockpit is sleek and clutter-free with wireless shifting (Team/Pro/Expert builds) and Pivot’s Phoenix Team Flat carbon bars. The new dual cable port system simplifies routing and improves serviceability.

Good quality and definitely worth it for energetic dogs.
Color: Orange
The automatic moving and rolling action really grabs my dog’s attention, and the rope adds extra fun for chasing and playing. It helps reduce boredom and keeps my dog mentally stimulated, especially when indoors. The motion activation works well, and it’s a fun and engaging toy overall.

Best Dog (Puppy) Toy I've Found
Color: Orange
This is a fun toy for me as well as my puppies! When it arrived I opened it right away. I was anxious to get my Pup's playing with something that wouldn't require me to play with them. I put it down and it was charged and ready to go. I had no idea what to expect. All three of my Pups were interested in it. (Which is unusual because two of them are Shih Tzu's and don't pay a lot of attention to most toys.) It's safe and really cute to watch. My youngest pup had been playing all day and was tired when I finally took a photo. I can't tell if the video uploaded correctly but if it did you can see how much fun it was. It is very durable and can actually turn itself over and go across the floor. It charges fast and will last a day and a half or two depending how much it's been used. It does go to sleep if no one is playing with it. They furnish you with an extra top and a fresh "rope." I really appreciate how much customer service is done with this item. I will watch for more of their items to purchase.

Buy 2 at a time for a fun experience
Color: Orange, Color: Orange
What’s better than 1 toy? Answer: 2 toys! I love using two at a time. More stimulation and fun! We use these to get all the energy out before nap time. They keep him occupied and running in two different directions. The rope part of the toy is the perfect size for him to grab onto. It came with a replacement for a wheel and rope and haven’t had to replace it yet. Toy has held up with daily play and still works perfectly.

How many dog toys have you bought that just laid on the floor unused?
Color: Orange
New husky has more energy than an entire pre-school - even being walked more than three miles a day wasn’t sufficient to drain her excess energy. I threw the dice on this - and it’s AWESOME. Comes with an extra rope and an extra side piece. Rechargeable with a USB-C cable. When you turn it on, the blue LEDs flash, the entire device buzzes, bounces, and races back and forth across the floor. After a couple of days of uncertainty, my new husky LOVES this. She chases it around, grabs it by the attached rope and carries it from room to room. After a short bit of activity, the toy goes into ‘sleep’ mode, until either the dog touches it again or a timer has elapsed, and then it fires up and starts buzzing and racing around the floor again. From a full charge, the toy will keep your dog entertained all day. Bright orange color makes it much easier to find when it’s rolled behind the toilet (as it did this afternoon). Sturdy. Highly resistant to chew damage. If this one wears out or breaks, I’ll absolutely get another one.

Puppy interactive toy
Color: Orange, Color: Orange
It’s a great toy as it keeps my 5 month old puppy very entertained! It is pretty hardy and made of good material as she tries to throw it around and chew it. She does swing it around and the hard part will hit her. She doesn’t seem bothered by it tho lol good size and minimum noise When I first introduced her to it she was a little scared but now she gets excited to play with it once it finishes charging.
