Shuttle AM

There are currently three classes of e-bikes: Class 1, Class 2 and Class 3.
Class 1 e-bikes, like the Shuttle AM, do not feature throttles. Instead, Class 1 e-bikes 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 e-bikes feature a throttle—in other words, Class 2 e-bikes can provide a power boost even when you aren’t pedaling. It’s a very different machine.
Class 3 e-bikes look and function similarly to Class 1—the difference is that the drive unit on a Class 3 e-bikes disengages once the bike hits 28 miles per hour.

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: 5'2" – 5’7"
Medium: 5'7" – 5'11"
Large: 5'10" – 6'2'
X-Large: 6'1"
We suggest that you pick your Shuttle AM size based on your riding style. The Shuttle AM 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.

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 a suspension set up guide included in your Shuttle AM’s owner's manual as well as a comprehensive suspension setup guide that can also be accessed under the Tech Specs tab.

The Drive unit provides 85Nm of torque, 340% of support and weighs 6.4lbs (2.9kg).
The limited edition CX race edition motor, found on Team builds, provides 85Nm of torque, 400% of support and weighs just 6.1lbs (2.75kg).
The Shuttle AM Team and Pro builds feature a 750 W/h battery that weighs 9.5lbs (4.3kg). The Ride builds come with a 625 W/h battery that weighs 8lbs (3.6kg).

Yes, Pivot worked with Bosch to customize their eBike Flow app specific for your Shuttle AM. The eBike Flow App from Bosch can be found in your phone’s app store. Follow the app to install and connect it to your bike to use all its features.

Yes, Bosch offers many display options for the Performance CX line. You can also use your smartphone as a display with the Bosch eBike Flow app.
Contact your local Pivot dealer for compatible options.

Using the Bosch eBike Connect app you can connect cycling apps and the following heart rate motors.
• Apple Watch
• Polar H7
• Polar H10 Heart Rate Sensor
• Runtastic Heart Rate Combo Monitor
• Wahoo TICKR Heart Rate Monitor
• BerryKing Heartbeat Brustgurt oder BerryKing HeartRate Armband Tracker

Yes, you can easily customize your system to better fit your local trails or your range preferences. You can adjust individual mode settings using the Bosch Flow App on your smartphone The system can have 4 different modes loaded on it, but there are more available from Bosch if you have different preferences.
The modes that come on RIDE and PRO builds are:
TOUR : Dynamic support for normal riding and biking sports.
EMTB-Shortcrank: Set for 160-165mm cranks. Optimal support whatever the terrain, rapid acceleration when starting from a standstill, improved dynamics and top performance.
SPORT: Optimal support whatever the terrain, rapid acceleration when starting from a standstill, improved dynamics and top performance.
TURBO: Maximum support even at a high cadence, for sport cycling.
TEAM builds come with:
EMTB-Shortcrank: Set for 160-165mm cranks. Optimal support whatever the terrain, rapid acceleration when starting from a standstill, improved dynamics and top performance.
SPORT: Optimal support whatever the terrain, rapid acceleration when starting from a standstill, improved dynamics and top performance.
TURBO: Maximum support even at a high cadence, for sport cycling.
RACE: *Only available on Limited Edition Race Motors. Maximum support on the eMTB race course, very direct response behavior and maximum “Extended Boost” for the best possible performance in competitive situations. This mode is so powerful it can be unmanageable in most trail riding situations. We recommend getting comfortable with the bike in the lower power modes before using this powerful mode. With great power comes great responsibility!
If you would like to use different modes that are not loaded on your bike you can replace them with other available modes. The additional modes available that can be loaded on your Shuttle AM by your Pivot dealer are:
ECO: Effective support with maximum efficiency, for maximum range.
TOUR: Steady support, long range touring.
EMTB: Optimal support whatever the terrain, rapid acceleration when starting from a standstill, improved dynamics and top performance.

The Shuttle AM battery is designed to be fully integrated into the frame. The battery can be removed with motor and charging port removal, but for regular charging use the charging port on the frame. However, you do have the option to use the Bosch PowerMore 250 range extender that can be charged off the bike.

Yes, Bosch has the PowerMore 250 that will be available in October 2023. This 250 W/h battery mounts to the frame and connects to the charging port on the frame. weighing only 3.5 pounds this extends your range without a costly weight penalty.

The Shuttle AM features the Bosch rim magnet speed sensor mounted to the rear wheel’s valve stem. This is sensed as it rotates past the motor. Make sure if you change wheels or get a flat on the trail to mount the magnet back on the valve stem or the system will not provide assist.
*You will need at least a 32mm long valve stem for the rim magnet.

31.6mm

S – 280mm
M – 300mm
L – 330mm
XL – 370mm
*Please check seat post measurements carefully before installing the post.

The Shuttle AM 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.
There are some limitations that each dropper post can accommodate for each frame size based on 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.
If your post is completely inserted into the frame you will want to check for tire clearance to your saddle at full travel. This is especially important on smaller frames.

The Shuttle AM frame uses a 36.4mm seatpost clamp, some manufacturers call it a 36.5mm.

The Shuttle AM uses the Universal Derailleur Hanger (UDH) standard developed by SRAM. This derailleur hanger is compatible with all derailleurs on the market – not just SRAM. We spec this hanger because it has some clever derailleur saving features and is more likely to be found at any shop and is also available in our webstore. Both Pro and Team level builds feature the new SRAM AXS Transmissions which utilize the UDH derailleur hanger mounting interface but do not use a derailleur hanger at all.

The Shuttle AM uses an axle for 157mm rear spacing designed for the new Universal Derailleur Hanger (UDH) standard. The rear axle supplied with the frame is a Pivot specific design using a 12mm X 1.0mm thread pitch. SRAM also makes compatible 157mm UDH axles. Pivot 157mm UDH compatible axles can be found in our webstore.

The Shuttle AM is optimized around a 34t chainring. You can use between a 30-38t chainring, but we recommend using a 34t or 36t chainring for the best performance from the DW-Link suspension, drive unit, and drivetrain.
Contact your Pivot Dealer if you would like to change chainring size to configure the settings properly for the drive system.

Contact your Pivot Dealer if you would like to change chainring size to configure the settings properly for the drive system.

The Shuttle AM can run 29” wheels with MAXXIS tires up to 2.5” wide. For other tires in the market, most will fit up to these dimensions. If you decide to change the tires or wheels that we have on our builds, we suggest you check the fit with your chosen rim and tire combination to make sure it has proper clearance.

The Shuttle AM is designed for a 200/203mm rear rotor. A 200mm or 203mm rotor are the only size rotor that can be used on the rear. On the front, we spec the Shuttle AM with a 203mm front rotor and an adaptor to convert from 180mm post mount to a 203mm post mount. The fork can also accept a 223mm rotor with the proper adaptor or a 180mm rotor with no adaptor.

The Shuttle AM uses a ZS (zero stack) 44mm top and (zero stack) 56mm bottom.

The Shuttle AM 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 e-bike wheels.

The cranks used on the Shuttle AM have a 176mm q-factor which is similar to a standard XT or Race Face trail bike crank on an analog bike.

The Fox forks available on the Shuttle AM builds still use standard fork architecture. This differs from Fox’s much heavier eMTB specific chassis for class 3 e-bikes.

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

No. Although the Shuttle AM is capable descending the steepest and roughest trails, it is only designed for use with single crown forks.

44mm

The Shuttle AM’s metric shock has a trunnion style upper mount, 185mm eye-to-eye length, and 55mm stroke.

The Shuttle AM shock features a trunnion style upper mount and uses M8 through bolt hardware on the bottom mount. Shock spacer dimensions are 30mm wide on the bottom mount. We typically run medium valving on the compression side (depending on rider weight) and medium rebound damping.

Larger volume spacers will resist bottoming, allow the bike to ride higher in the stroke and generally make the bike feel more “poppy”. If a rider is not getting full stroke or they feel that the bike is riding too high in its stroke, even with sag set properly, then they should go to a smaller volume spacer.

The Shuttle AM Float X shock uses a .4 cu in volume spacer. The Shuttle AM’s Float X will fit volume spacers from none up to 1.0 cu in with 0.1cu inch increments. The Float X uses a primary volume spacer that comes in 0.2cu inch increments like normal, and you can also “piggyback” a small 0.1cu in spacer to make smaller adjustments. The shock can handle larger spacers for a more progressive feel or smaller spacers for a more linear feel. For a more linear feel, using between 0.1-0.3 cu in volume spacers can be installed. For a more progressive feel, using between 0.5-1.0 cu in volume spacer can be installed. 1.0 cu in is the maximum amount of volume spacers for this shock. Please see the chart below for spacer P/N’s.

P/N Description
233-00-521 Volume Spacer: Float X 0.10in^3 Plastic, Mint
233-00-522 Volume Spacer: Float X 0.20in^3 Plastic, Tennis Ball

Yes, the Shuttle AM features a rising-rate design that functions well with coil-over shocks. We recommend and spec Fox DHX2 for their best in class performance, reliability, and adjustability.
Please check all clearances prior to using any shock other than those spec’d or specifically recommended by Pivot. Your Shuttle AM will not be covered under warranty if damage occurs due to shock incompatibility.

The flip chip is a simple way to adjust the Shuttle AM’s geometry for different trail conditions. The chip comes set up in the low BB setting. This is perfect for riding fast, technical and steep terrain. However, if your preference is for a little more crank clearance and slightly quicker handling for tighter terrain with more climbing and/or roots and rocks, you may prefer the high BB setting. The high BB setting will raise the bottom bracket and steepen the head angle by .5° degree giving the bike faster turn in.

The Shuttle AM’s flip chip geometry adjustment system is super easy to use. Simply loosen using a 6mm hex wrench (these are reverse, so you need to turn the wrench to the right to loosen). Partially back out the bolts – there is no need to completely remove the bolts. Then pull the chips out and rotate them to your desired position, tighten the bolts to 35 Nm and enjoy your bike’s new handling and feel. Please see the geometry chart for the numbers associated with the different settings.

It is possible, if you really want to set it up with mixed wheels. You will need to buy a super boost 157mm x 27.5” rear wheel. The mixed wheel setup will slacken the Shuttle AM headtube angle and drop the bottom bracket height so you will want to run the flip chip in the “high” position to maintain proper geometry. If running a 27.5” rear wheel, we suggest running a 2.6” rear tire.

The Shuttle AM includes an upper chainguide. It does not have ISCG tabs so most aftermarket chainguides will not fit on the Shuttle AM.

The Shuttle AM Team XTR bike weighs 47.9lbs. (21.7kg.) – Yes, that is with a 750Wh battery! 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 AM. 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 AM. Bring a scale if you’d like, but take just one demo ride and you’ll feel why the Shuttle AM is the most well-rounded, highest performing long-travel e-bike on the market and, yes, it is among the lightest as well.

330lbs (149kg) for the rider plus any payload or accessory such as a hydration pack. Also, note that maximum air pressure for the Shuttle AM’s Fox Float X shock is 350 PSI – within the range needed to achieve proper sag settings up to the bike’s weight limit.

A detailed PDF of the torque specs can be found in our Small Parts Schematic under "Tech Specs".

SRAM AXS Transmission has a unique installation process that you must follow to set up this drivetrain on your Shuttle AM properly. The compete installation instructions can be found at https://www.sram.com/en/service/browse-by-product
Refer to SRAM’s chain length calculator for the proper setup information and chain sizing https://axs.sram.com/guides/chain/calculator

All components and parts of the Bosch CX system are protected against the ingress of moisture and dust according to IP54. This means that the system is protected from water splashing from any angle but is not rated for high pressure spray or immersion.

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 you’ll demand more energy from the battery than if you are operating the bike in less powerful (Eco or Tour) modes.
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—Turbo 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 Tour 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, Tour, Sport and Turbo 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. The Shuttle AM’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.

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 AM 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 AM 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. It is also against the law.

Drive units are completely sealed in order to keep the electronics and mechanical pieces perfectly clean year after year. Like most Bosch components, it has a 2 year warranty. If something
mechanical were to fail after that point, the solution would be to contact Bosch for repair or replacement of the drive unit.

In the unlikely event of a drive unit malfunction, your Shuttle AM is still absolutely ride-worthy. We designed the Shuttle AM 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 Switchblade. True, the Shuttle AM 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 even 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.

No, the Shuttle AM doesn’t have a throttle. Instead, it’s a Class 1 pedal-assist style e-bike. In other words, the Shuttle AM’s 250-watt electric drive unit assists your own pedaling effort. You can choose between four different pedal-assisting power modes while riding (Eco, Tour, EMTB/Sport, and Turbo) 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 AM’s motor no longer assists once the rider reaches 20 miles per hour (25 kph in EU specification)—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.

No. Any aftermarket linkage not approved by Pivot immediately voids the frame warranty for any issue that could occur related to these aftermarket parts.
