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: 5'4" – 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).

The short answer is no—not yet in America. eMTBs are still relatively new to the United States; laws and policies regarding where you can and can’t ride one are just now being created. 

Class 1 eMTBs, like the Shuttle, are permitted on all trails already open to motor vehicles, such as motorcycles. 

Your ability to ride a Class 1 eMTB on trails that are closed to motorized traffic, however, varies from state to state and, in some cases, county to county. The number of non-motorized trails open to the Shuttle and other Class 1 eMTBs, however, is growing as land managers learn more about the different types of eMTBs. 

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 owners 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 about 2-3 minutes with the use of a T25 Torx  wrench.  A full battery swap can even be performed on the trail in about 5 minutes for those wanting to carry an additional battery for those 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.

Shimano states that it can take up to 5 hours to recharge the battery from being completely dead.   In our experience, it’s hard to completely drain that battery and a battery with some charge tends to charge faster.  Even with 1 bar left, charge time usually not more than 3.5 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. 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. Shimano states that you can ride 25 miles in the most powerful Boost mode, 40 miles in Trail mode and 55 miles in Eco mode. Those estimates are based on a rider weighing 180 pounds. 

Here’s our own experience: In our several years of testing this system, we’ve found that most of our rides involve shifting between the different modes—Boost winds up providing more power than you want on descents, flats or (unless you are completely bonked) even rolling terrain. Accordingly, when we start our rides with a fully-charged battery showing five energy bars on the display, we can routinely finish a 3 to 4-hour ride with 1 or 2 energy bars still showing on the display. If you were riding in strictly Trail or Eco mode, you can complete even longer days in the saddle on a single charge. A rider on a technical ride with a fair amount of climbing that switches between Eco, Trail and Boost as the terrain varies can do a 5 hour ride which is quite the adventure for most riders. 

All rechargeable batteries gradually store less power with each recharge. Shimano’s lithium-ion battery, however, provides up to twice as many recharge cycles as most competing batteries. The norm for an eMTB is about 500 charge cycles. Shimano’s battery unit is designed to provide 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 Shimano lithium-ion battery that we use on the Shuttle retails for $599.

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 and take fun and performance out of the system in the areas and speeds you ride most.  If you are already over 20mph, most likely you are flying down hill and don’t need more assist.  If you climbing up hill and you’ve gone over 20mph, then 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 that your Shuttle remains the Class 1 eMTB that it was intended to be and can be ridden in more places without a negative impact on trail access.  Additionally, leaving your drive unit stock means that 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 Mach 5.5 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.

It means that you were sitting on the bike when you turned the power on. This is the most common error code.  It appears when there is any weight on the bike while powering on the battery. 

To reset, Turn the system off by pressing the power button on the top of the downtube.  Make sure you are not sitting on the saddle or putting any pressure on the pedals, and then turn the system back on - once the system has fully turned on, you may then hop back on and go for your ride. 

Please note, the system will automatically power off after approximately 5 minutes when the bike is no longer in motion.  You will need to turn the system back on without putting any weight on the saddle or any pressure on the pedals.  We advise to always turn the system on before you get on the bike.  All the common error codes can be found in your owner’s manual which also available in the tech documents section of the Shuttle page.

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 wheels on the Shuttle take eMTB wheel strength, stiffness and lightweight to another level. 

Super Boost Plus 157 uses the existing chainline developed for DH bikes but uses standard Shimano E8000 and E7000 compatible cranks and chainrings.  Super Boost Plus 157 optimizes the entire eMTB system by moving the drivetrain outboard (3mm over Boost) resulting in increased tire and mud clearance, a stiffer overall frame design and the ability to run shorter chainstays*.  The Super Boost Plus 157 idea has enabled us to build the New Shuttle with a level of performance unattainable with other designs in the market.

* Short Sub-437mm (17.2”) chainstays perfectly complements the Shuttle’s long and low stature allowing you to manual up and over even the gnarliest obstacles while keeping the wheelbase length in check so that you can still clean tight switchbacks and rail corners with confidence and agility like you’ve never experienced before.

The XT cranks used on the Shuttle, in conjunction with the Shimano drive units, has the same Q factor as a standard Shimano XT crankset, which is 174mm. 

The 2019 Shuttle XTR Team bike weighs 44.75 lb. (20.29 kg.) while the Shuttle XT Race model weighs 1.5lbs. (.68kg.) more. Pivot bicycles are among the lightest available, but the weight is only one of many factors that make a great bicycle. Other aspects such as frame stiffness, strength, durability, and ride quality 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 see our attention to detail, smart, high-value spec, and class-leading features, but most of all the incredible performance of the new Shuttle. 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 and 150mm dropper on the Medium - X-Large.  There are some limitations that 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 for either a 150mm or 160mm fork. First generation Shuttles came with a 150mm, 51mm offset fork. The latest Shuttle comes spec’d with a 160mm travel fork with 44mm offset. The maximum travel length that can be used on the Shuttle is 160mm travel.

44mm

Both Shuttle models come 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 2.5” wide (Maxxis Assegai) and 27.5”+ tires up to 3” inches 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.

Eye-to-eye: 7.875" (200mm)

Stroke: 2" (50.8mm)

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.
