FAQ:
| Can I use the Keystone in cold temperatures? | It is okay to use your Keystone in the operating temperature range, suggest by Shimano: -10 - 50°C |
| How do I remove the battery? | Each Keystone will come with a set of keys. Make sure to save your spare key and safe location. Insert the key fully into the lock cylinder on the non drive side of the downtube until it stops. Rotate the key clockwise until the battery drops from the downtube providing access to the latch release mechanism. Use your index finger to gently depress the spring which will fully release the battery. Use caution to support the battery when removing it so it does not fall to the ground. |
| How can I file a warranty claim for the drive unit and other electronic components? | Contact an authorized Shimano STEPS dealer. |
| Can I change my motor/power settings? | Yes, you can customize your motor settings via the app as well as update the firmware. You'll need to download the Shimano E-tube mobile app. |
| Can I change the max speed? | No. Depending on where you've purchased your Keystone it will either have a max assist speed of 20mph or 25km/h. This setting cannot be modified by the user or a dealer. |
| Can I purchase an extra battery? | Yes, you can purchase a spare battery kit with a spare downtube cover directly from Borealis. Spare battery kits may not be available in all markets. You can also purchase a spare battery from Shimano, but it will not include a battery cover. |
| Can I ride the Keystone without the battery? | No. This will void your warranty with Shimano and cause damage to the motor system. |
| Do I need to update the firmware / software? | Firmware can be updated via the Shimano E-tube mobile app. |
| How do I use walk mode? | Hold the upper button (down assistance level) for 1 second until the display turns blue and displays WALK mode. Press and hold the same button to power the rear wheel. |
| How long does it take to charge the Shimano 630Wh Battery? | With the included EC-E8004 charger, the battery can fully charge in 6 hours. |
| How long will my battery last? | The remaining battery capacity is affected by temperature and cycle count. Generally, it decreases approximately 5% a year. This means roughly 95% capacity remains after 1 year, and 90% after 2 years. |
| How should I store my bike and or battery? | Charge your battery to approximately 70% before storing for long periods of time. Store in a cool, indoor location with a stable temperature between approximately 10 - 20 C / 50 - 70 F. No direct exposure to sunlight or rain. |
| Are the electronic components waterproof? | Yes, the STEPS system is waterproof as long as all components of the system, including the battery and battery cover, are installed correctly. We recommend not using a high-pressure washer to clean your Repeater, but riding in the rain and regular cleaning are okay. |
| My bike won't turn on, what do I do? | First, make sure all cables are plugged in, if they are then try removing and reinstalling the battery. If it still won't turn on try charging your bike for a few hours. If your bike is too hot or too cold, it might not turn on. If your bike still does not turn on, contact a Transition or Shimano dealer for support. |
| Should I only charge my battery when it's completely drained? | No, simply charge the battery any time you need it, frequent charges actually help battery longevity. Avoid letting the battery discharge completely. Charge to 70% before storing for long periods. |
| What are the different error codes and what do they mean? | Whenever you encounter an error code, first cycle the power off and then back on. If the code persists, remove the battery and then reinstall, which will hard reset the system. If neither of these steps resolves the issue, please reference the Shimano error code list. If you cannot resolve your error code via your Etube mobile app please visit your nearest Shimano STEPS dealer or contact Shimano STEPS customer support. |
| What is the range and how can I maximize it? | There are many factors that affect battery range, such as, how much effort the rider is providing, the gradient of terrain, ambient temperature, and rider weight. The best way to maximize your range it to spend more time in Eco and Trail modes, and minimize the amount of time spent in Boost mode. |
| What is the widest tire the Keystone can fit? | 26x5.0" or 27.5x4.5" |
| What kind of maintenance is needed on the drive unit and how often? | The drive unit is sealed and cannot be serviced. If there are any issues with the drive unit, it will need to be removed and sent back to Shimano for service or replacement. The drive unit along with the battery is designed to last over 1000 charge cycles. Assuming you're getting 30 miles (48Km) per charge, the drive unit should last 30,000 miles, or much longer than pretty much any other part on your bike. |
| Why does my bike stop giving assistance over a certain speed? | Depending on where you've purchased your Keystone it will either have a max assist speed of 20mph or 25km/h. This setting cannot be modified by the user or a dealer. |
| Will environmental temperature affect battery life? | The battery life will be shorter during cold temperatures, this is not a sign of a problem. |
| Will my bike be delivered with a charged battery? | Your Keystone was shipped in a "sleep" mode with the battery at approximately 30% charge. It is recommended to fully charge your battery before the first ride. |

Dazzling, Exhaustive, Exhausting.
Format: Kindle
Mr. Tooze has delivered a tour de force. He has marshaled what surely must be the most comprehensive and informed account of the 2008 crash and its aftermath. Tooze examines in detail and at length, the financial, economic and political forces at work in this gigantic mosaic of global crisis. And he clearly understands the process, providing shrewd insights and informed commentary. It's a heavy lift--a bit like trying to drink out a a fire hydrant; the sheer volume of information is daunting. But the prose is clear and accessible.
Tooze clearly identifies with the the leaders and institutions that mobilized themselves in new and highly unorthodox programs to contain the crisis. That's not popular among critics on both the far left and the hard right. But he illustrates the vapidity of their carping--which largely constitutes a substitute eitherfor understanding the issues or crafting workable solutions.
I would argue that he overlooks the opportunity Obama had in January 200i9 to bend both parties to his will in crafting a real Economic Stimulus plan that the nation could have embraced. Instead he passed the initiative to the House leadership who simply dredged up failed old chestnuts which they newly christened as stimulus programs. Obama bought in and launched its initiative as a partisan weapon--which has only served to widen the current divide. An activist approach that would have drawn from both Republican and Democratic resources--and which was actually directed as a stimulus--might have created a moderate center from which to conduct his business. We'll never know. Obama didn't ever buy into working with others--even n his own party. It was generally his way of the highway. But it's tempting to look back and consider the possibilities.
His concluding message, asks what resources will the current administration--which eschews both institutions and expertise--be able to mobilize in the all too likely event some new global crisis hits.
For now, read and enjoy the (long) but very well informed ride.

Excellent history of 2008 financial crisis
Format: Kindle
As a non-economist, I wanted to learn about the causes and consequences of the 2008 financial crisis. Overall, Tooze has created what will likely become the definitive history of the crisis. He tells an incredibly detailed story of the rise of power among international banks, and how these banks created securities around mortgages that concealed their riskiness. The blow by blow story often had me in high suspense, testifying to the power of how Tooze put together the background events - and fininacial instruments of mass destruction - that nearly gave us WW Depression 2.0. Personally, I come away with great respect for Paulson, Berneke, Geitner, to name the key actors in this drama - for saving the world economy from ruins. I also come away with an unsolved mystery: why did America not fill its jails with crooked bankers? Yes, I understand from Tooze that the US Fed and Treasury were bankers, and disliked immensely turning in their own. But, zero bankers in jail, after causing what Tooze argues was the greatest bank crisis, ever, including Great Depression 1.0.? It makes no political sense that banks and their leaders nearly destroyed the world economy, but zero went jail, when millions across the world lost homes to foreclosure, suffered severe unemployment, had Democratic election results ignored by financial authorities (mainly in Europe). I am personally convinced this lack of fairness and justice has given us not only Trump but a broad range of autocratic political parties. They claim to protect everyday people, but of course do not. In sum, this rather masterpiece of historical financial analysis is a surefooted guide across the tricky lengthy and politically dangerous terrain of the 2008 financial crisis. Five stars.

2008 Neoliberalism crashes the state rushes back-- just in time
Format: Kindle
“Whereas since the 1970s the incessant mantra of the spokespeople of the financial industry had been free markets and light touch regulation, what they were now demanding was the mobilization of all of the resources of the state to save society’s financial infrastructure from a threat of systemic implosion, a threat they likened to a military emergency.” (Loc. 3172-3174)
Adam Tooze takes the well know Financial Crisis of 2007-08 through its full history of international ramifications and brings it up to the present with the question of whether the large organizations, structures and processes on the one hand; decision, debate, argument and action on the other that managed to fall into place in that crisis period in this and many other countries will develop if needed again. “The political in “political economy” demands to be taken seriously.” (Loc. 11694). That he does.
Tooze is an Economic Historian and Crashed: How a Decade of Financial Crises Changed the World is a wonderfully rich enquiry into causes and effects of the Financial Crisis and how the failing of poorly managed greed motivated practices of a few financial institutions, and their subprime mortgagees, tumbled economies in the developed and developing world, causing events that matched the Great Depression’s dislocation and could have matched its duration, springing from world wide money markets “interlocking matrix” of corporate balance sheets— bank to bank.”
A warning he is not kind to existing political beings, the Republican Party in particular “…to judge by the record of the last ten years, it is incapable of legislating or cooperating effectively in government.” (Loc.11704)
His criticism is, in fairness, based on technical management grounds, and he does find fault as well with the inner core of the Obama advisors and their primary concerns for the financial sectors well being, rather than nationwide happenings where homes and incomes disappeared.
This reviewer’s favorite (not mentioned by Tooze) is the early 2009 comment of Larry Sumners when Christina D. Romer, the chairwoman of President Obama’s Council of Economic Advisers and leading authority on the Great Depression saw a need for $1.8 trillion stimulus package, “What have you been smoking?”
Sumners, Geithner, and Orszag, who favored transferring $787 billion to the banks to offset possible bank failures and such -- became policy. Tooze mentions that by 2012 Sumners was concerned by the slowness of the U.S. economy’s recovery taking, as it did, 8 years to reach 2008 levels of employment.*
Can an Economic History be an exciting read? Tooze gives us over 700 pages of just that, but much will be familiar as reported news and may be skimmed, and some of the Fed’s expanded international roles very dense in content. His strength is the knowledge of what could have happened, had solutions not been found, and how agreements were reached out of public sight.
“… the world economy is not run by medium-sized … entrepreneurs but by a few thousand massive corporations, with interlocking shareholdings controlled by a tiny group of asset managers. (Loc.418-419).
Add wily politicians and hard driven bankers EU Ukraine and China you have an adventure.
Corporate control is not new -- rich descriptions of its inner connections are.
Adam Tooze does this well a reference work for years to come.
5 stars

Spectacular story everyone should read
Format: Kindle
Although long, this book is simply a spectacular story that everyone should read. Even for the most informed, you will learn something new in every chapter. The 2008 financial crash is one of those rare events that will effect almost everyone on earth and certainly everyone in the US. As Tooze details, that crash is going to cost the US more than $20 trillion and has caused deep and dramatic social and political upheavals. The impact in Europe and around the world has been and continues to be no less far-reaching. For anyone who wants to understand the social, cultural, political and economic fault lines around the world today, this book is a must-read. It's deeply informed, comprehensive and insightful in surprising ways even for those who think they've already read everything worthwhile about the financial crash, economic crisis and political developments. Read it and then give it to someone else to read (or buy them one as a gift!).
