Shuttle

To ensure the best sizing, we recommend that you visit your local Pivot dealer to get a professional fit and refer to our geometry chart to check your measurements. We can, however, provide a rough guideline to get you started. These recommendations are based on our experience, athlete preference and customer feedback:

Small: 5'3" – 5'7"

Medium: 5'7" – 5'11"

Large: 5'11" – 6'2'

X-Large: 6'2" +

We suggest that you pick your Shuttle size based on your riding style. The Shuttle features trail bike long and low geometry with shorter seat tube measurements per size – this geometry means that most riders can go up or down a size and should base their choice on riding-style, reach and stem length preferences. Be sure to also consult our dropper post fit guide when making your selection. You can always reach out to us on Live Chat for additional guidance. 

No, the Shuttle doesn’t have a throttle. Instead, it’s a pedal-assist style eMTB. In other words, the Shuttle’s 250-watt electric drive unit assists your own pedaling effort. You can choose between three different pedal-assisting power modes while riding (Eco, Trail, and Boost) and you can change from one to the other by using a thumb shifter that’s a lot like a typical gear shifter. 

The Shuttle’s battery no longer assists once the rider reaches 20 miles per hour—at that point, it’s like you’re riding a regular mountain bike. As with any mountain bike, your downhill speed is a function of your riding skill, trail conditions and the design of the trail system you happen to be riding.

There are currently three classes of eMTB: Class 1, Class 2 and Class 3. 

Class 1 eMTBs, like the Shuttle, do not feature throttles. Instead, Class 1 eMTBs are equipped with a battery and a drive unit that assists your own pedaling effort. That system only assists when you are pedaling. In addition, the system stops assisting the moment the bike reaches a speed of 20 miles per hour in the United States and 25 KM/H in Europe. 

Class 2 eMTBs feature a throttle—in other words, Class 2 eMTBs can provide a power boost even when you aren’t pedaling. It’s a very different machine.

Class 3 eMTBs look and function similarly to Class 1—the difference is that the drive unit on a Class 3 eMTB disengages once the bike hits 28 miles per hour.  Class 3 eMTBs allow for higher speeds and are typically regulated like dirt bikes and other OHV’s (off-highway vehicles).

You have a few options. If after consulting the resources below, you are still unsure whether a trail you’d like to ride is open to a Class 1 eMTB like the Shuttle, try to contact the land manager in question.

We make it easy to get the best ride out of your Pivot bike with a simple sag indicator already installed on your bike, and this follow-along video featuring our own Bernard Kerr. There is also a complete shock set up guide included in your Shuttle’s owner’s manual that can also be accessed under the Tech Specs tab. 

Although the Shuttle battery is designed to be fully integrated into the frame without the need to remove it for charging, it can still be removed in less than a minute.  A full battery swap can even be performed on the trail for those wanting to carry an additional battery for extra-long adventures.  We’ve included simple instructions showing how to remove the battery in your Shuttle’s owner’s manual that can be accessed in the Tech Specs.  For charging off the bike, an additional adaptor is required and can be purchased through your local dealer.   

It can take up to 5 hours to recharge the battery from being completely dead.   In our experience, it’s hard to completely drain this battery; and a battery with some charge tends to charge faster.  Even with only one bar left, charge time is approximately 2 to 2.5 hours.  

There is no single answer to this question—it really depends on how much you are asking of the battery and drive unit during your ride.  Total climbing miles (elevation gain) and rider weight are also factors impacting battery life.   If you do your entire ride in the most powerful pedal-assist mode (Boost), you’ll demand more energy from the battery than if you are operating the bike in less powerful (Trail or Eco) modes. On average, you can ride 2 to 3 hours in the most powerful Boost mode, 3 to 5 hours in Trail mode and 5 to 7 hours in Eco mode. Those estimates are based on a rider weighing 180 pounds. 

Our in-house testing led to the following conclusions: the new 726 Wh battery is really difficult for an average rider to expend on even a 3 to 4-hour ride when using a combination of Eco, Trail and Boost.  The new EP8 motor is even more efficient at delivering the power when you need it and can access the full 85Nm of torque in the Trail setting, which means most riders will rarely need to access the Boost mode.   A rider on a technical ride with a fair amount of climbing (2,000 to 4,000 ft) - switching between Eco, Trail and Boost as the terrain varies -  can complete a 5 to 6 hour ride, which is quite an adventure for most riders.  

All rechargeable batteries gradually store less power with each recharge. The 726 Wh Darfon lithium-ion battery used on the Shuttle should provide up to 1,000 recharges before it reaches the point at which replacing the battery is advised. At that point, the battery will hold 60% of its capacity vs. when new.

The 726 W/hr. battery lithium-ion battery that comes standard on the Shuttle retails for $999.99.  Shuttle batteries are available for purchase from Pivot dealers.

The Shimano EP8 drive unit is 380 grams lighter, 21% more powerful, more efficient and has less drag than E-8000.  EP8 is completely different from E-8000 – parts are not compatible with each other. 

Generally, no.  We have heard of hacks that move or remove the top speed limitations, or artificially change the wheel size to gain more top speed assist.  However, these hacks generally result in a loss of torque, effectively removing performance (and fun) from the system under the conditions and speeds you ride most.  If you are already over 20mph, most likely you are flying downhill and don’t need more assist.  If you climb up hill at speeds exceeding 20mph, congratulations!  You are one incredibly fit individual, and you also don’t need additional assist.  Although it’s in our nature to always want a little more, in the long run it’s best to make sure your Shuttle remains the Class 1 eMTB it was intended to be, ensuring that bikes in this class can be ridden in more places without negatively impacting trail access.  Additionally, leaving your drive unit in its original stock settings means your warranty will stay intact.  The Shuttle was not designed or tested to be run with a setting that is more powerful and/or changes or removes the top speed limits for the battery assist.  Changes in the stock system will void the warranty, not just of the system, but of your entire bike.   

Drive units are completely sealed in order to keep the electronics and mechanical pieces perfectly clean year after year.  Like most Shimano components, it has a 2 year warranty.  If something mechanical were to fail after that point, the solution would be to contact Shimano for repair or replacement of the drive unit.  Firmware related problems may still be solved by a dealer with the Shimano PC connector.  

In the unlikely event of a drive unit malfunction, your Shuttle is still absolutely ride-worthy. We designed the Shuttle to be a great mountain bike—even with the pedal assist disengaged. Thanks to the dw link design, the bike pedals efficiently. It’s a bit like riding a cross between a Switchblade and a Firebird. True, the Shuttle weighs more than its non-motorized siblings, and you’ll feel that with the drive unit turned off (there’s no getting around physics), but it’s still fun to ride with the drive unit turned off. 

Beyond occasional firmware updates, there is no maintenance required on the drive unit.  The clean environment that keeps the electronics happy also keeps the gears and bearings running smoothly for years.  The chainring is easily removable so that it can be replaced after regular drive train wear.

The Shuttle uses a 157mm rear hub spacing in a configuration called Super Boost Plus 157. Super Boost Plus 157 builds on the idea of wider flange spacing pioneered by Boost 148. Super Boost Plus spreads the flanges even wider (up to 14mm wider then a 142mm hub) and increases wheel stiffness substantially (Approximately 30% stiffer than boost), which is a huge benefit on eMTB wheels. Our custom developed DT Swiss eMTB specific wheels on the Shuttle take eMTB wheel strength, stiffness and lightweight to another level. 

The new dedicated EP8 cranks used on the Shuttle has a 175mm q-factor – this is 2mm less than E-8000.

The 2021 Shuttle XTR Team bike weighs 48.75lbs. (22kg.) Pivot bicycles are among the lightest available, but we believe weight is only one of many factors that make a great bicycle. Other aspects such as frame stiffness, strength, durability, ride quality - and in the case of the Shuttle - large battery capacity and a Fox 38 fork are just as important as weight to our engineers when designing the Shuttle. Instead of comparing grams, we suggest you visit your local Pivot dealer and learn fully about our attention to detail, smart, high-value spec, and class-leading features. Most of all, we recommend considering the Shuttle’s weight in the context of its incredible performance. Bring a scale if you’d like but take just one demo ride and you’ll feel why the Shuttle is the most well-rounded, highest performing eMTB on the market. And yes, it is among the lightest as well.

30.9mm

The Shuttle features a low stand-over height and short seat tubes to allow the use of longer travel dropper posts and/or more flexibility for a wider range of rider sizes.

The Shuttle comes equipped with a 125mm Fox dropper on the small frame size, a 150mm dropper on the Medium and Large sizes, and a 175 mm Fox dropper on the X-Large.  There are some limitations to what each dropper post can accommodate for each frame size based on the individual rider’s saddle height.  Use the Dropper Fit Guide (found under Tech Specs) to determine if the included dropper post will work correctly for the size bike that you are considering.  

The Shuttle was designed to use a 160mm fork. The maximum travel length that can be used on the Shuttle is 160mm travel.

44mm

Yes, the Shuttle’s 38 fork comes with Fox’s eMTB specific tune and certification.  This differs from Fox’s much heavier eMTB specific chassis for class 3 ebikes.  

The Shuttle can run 29” wheels with tires up to 2.4” wide (Maxxis DHRII) and 27.5”+ tires up to 3” inch wide (Maxxis Chronical). 

The Shuttle was designed for a 180mm rear rotor and features a 180mm post mount design, so you cannot fit a 160mm rotor on the Shuttle. A 203mm rotor will fit with the use of a post mount caliper adapter. The front brake comes with a 203mm rotor, which uses a 180mm-to-203mm post mount adapter. 

No brake adapter is needed for a 180mm rotor. However, if you'd prefer to run a 203mm rotor, you would need a proper direct mount/post to post adapter to go from a 180mm to 203mm rotor.

The Shuttle uses a ZS (zero stack) 44mm top and (zero stack) 56mm bottom, or a Chris King Inset 2.

Pivot uses a 1.5 thread pitch on the rear thru axle. You can order one through our online store.

The Shuttle’s metric shock has a 210mm eye-to-eye and 50mm stroke.

The Shuttle shock uses M8 through bolt hardware on the front and no hardware on the rear. Shock spacer dimensions are 22mm wide front. On the rear of the shock, the spacer hardware and bushing will need to be removed as the rocker mounts directly to the shock body. Some shocks may have a different spec then the Fox shock (that the Shuttle is designed for) and may not fit properly. Also, as we cannot test every shock on the market, riders assume some risk if they choose a shock that does not fit properly or is not tuned correctly for the bike. The frame is designed around a large volume air can. We run medium compression valving and medium rebound damping.

You cannot run a coil-over on your Shuttle! The Shuttle was designed to work with the progressiveness of an air spring. A coil-over shock (even one with separate bottoming control) does not offer the progressive spring curve that the Shuttle requires. Running a coil-over shock on the Shuttle will result in hard bottoming and damage to the frame. Running a coil-over shock on the Shuttle will also VOID the frame’s warranty!  

286lbs (130kg) for the rider plus any payload or accessory such as a hydration pack. Also, note that maximum air pressure for the Shuttle’s Fox DPX2 shock is 350 PSI – within the range needed to achieve proper sag settings up to the bike’s weight limit.
