TECHNICAL FAQ

Q: What torque settings do I need to use on my CUBE bike?

A: Please tighten all parts in accordance with the manufacturer’s maximum torque specifications as stated on the part itself. Always use a torque wrench when fitting carbon fibre parts and apply carbon paste to reduce the tightening torque. For your own safety, please check regularly that all screws are tightened to the correct torque. You’ll find all the relevant torque settings here:

Q: I want to upgrade my bike with longer travel suspension. Is that permitted?

A: When swapping suspension components, ensure that the new parts have the same dimensions as the originals. With rear shocks, pay special attention to the eye-to-eye length, the width of the end bushings and the body. These must be the same size as on the original shock. Using components of other sizes will impact negatively on ride performance and can even damage the bike frame. For suspension forks, check that the new fork has the same travel as the original, as the length when installed will in most cases only be minimally different.

Q: Can I install forks with more travel than standard?

A: No. The installation of a fork with more travel will void the warranty. The bike’s geometry will be adversely affected, leading to undesirable handling and, potentially, permanent frame damage.

Q: How do I setup FOX forks/shocks correctly for my body weight and intended use?
Q: Up to which brake disc diameter is my CUBE bike approved?

A: Only brake disc rotors with the same maximum diameter as the original rotors that were mounted to that specific model, series and year are authorised. This applies to both the front and rear brakes, even if the fork manufacturer specifies compatibility with larger rotors.

Q: What is the maximum tire width I can use on my CUBE bike?

A: To determine tyre widths, each model was tested with the appropriate width rims. Widths are based on Schwalbe tyres – bear in mind that tyre width measurements can vary from manufacturer to manufacturer.

Q: What is the use category of my CUBE bike and what do I need to be aware of?

A: Every model of bike we sell is classified under a specific use category. You can find this information on our website. Please pay attention to the instructions on correct usage and the dos and don’ts for your model.

Q: Can I install a carrier of my CUBE bike?

A: All CUBE bikes that have a factory-installed carrier are, of course, approved for carrier installation, as are aluminium hardtail frames with rack mounting points (at the dropouts and at the top of the seatstays). Carbon seatposts are generally not suitable for seatpost-mounted carriers, because the clamping force can notch the post and cause sudden breakage.

 

Excluded from carrier use: all carbon bikes including carbon full suspension, carbon hardtails and carbon racing road bikes. The combination carbon frame / aluminum seatpost is also unsuitable for mounting a seatpost-mounted carrier.

 

The stresses caused by using a luggage carrier can harm carbon frames in the longer term. This can lead to unexpected breakage of the frame and serious accidents.

 

Important: Please note that when using kickstands, mudguards, luggage carriers, as well as bicycle trailers the application area of the model always changes to classification category 2.

Q: Can I mount a child trailer on my CUBE bike?

A: Yes. It is important to ensure that the trailer is mounted by axle-hitch. This works with bikes that have quick-release dropouts. Be sure that the maximum permitted weight is not exceeded. A trailer is a luggage component.

Exceptions:

  • All race bikes
  • All carbon frames
  • Full suspension bikes with X12 or Maxle floating axle (Sting HPC, Stereo ab 2009, Stereo HPC, all Fritzz)

 

Important: Please note that when using kickstands, mudguards, luggage carriers, as well as bicycle trailers the application area of the model always changes to classification category 2.

Q: Can I mount any bottle cage?

A: No. CUBE bikes are approved for bottle cages designed to hold bottles with a maximum capacity of 750ml.

Q: Can I use a Rohloff internal gear hub on my CUBE bike?

A: Yes. CUBE frames with a disk brake mounting are approved for the use of Rohloff hubs. The following needs to be considered:

Exceptions:

  • All bikes with electrical support (pedelecs)
  • All Bikes with rear suspension (fullsuspension bikes)
Q: What kind of kickstand can I use for my CUBE bike?

A: Universal rear kickstands designed for mounting on both the chainstay and seatstay will fit on all hardtail frames.

 

Exceptions:

  • All full suspension bikes
  • All carbon frames

 

It is important to ensure that a protective rubber shim is installed between the stand and the frame. Kickstands that are mounted directly to the chainstay are not recommended because long-term damage to the chainstay may result.

Q: Can I transport my CUBE bike on the roof rack of my car?

A: Fork-mounted racks – where the bike is secured at the rear wheel and the fork – are fine. Race bikes with carbon fork front ends are an exception. Roof racks that clamp the bike on the down tube are not suitable – this kind of fitting may damage the tube permanently.

Rear carriers, where the bicycle is supported on both wheels and secured via a clamp to the top tube, are usually suitable for aluminum frames. The best way to transport the bike is in the car. This protects against theft and is more gentle to your bike.

Q: Can I use my CUBE bike on a bicycle trainer?

A: Yes. However, all full suspension and carbon frames are excluded. Carbon frames can be seriously damaged by permanently fixing the bike on the bicycle trainer.

Q: How do I service and adjust my belt drive accordingly?
Q: Is it possible to repair a damaged carbon frame?

A: CUBE does not offer a repair service for carbon-frame bikes. We advise against repairing damaged carbon. The carbon fibres may suffer extensive structural damage that is not visible to the naked eye. If in doubt, always replace carbon parts immediately.

Q: Can I have my bike/frame security coded?

A: A security code is a combination of letters and numbers that is usually etched or stamped onto the frame by the police or another official organisation. Security codes help to deter would-be thieves and to identify the rightful owner of a stolen bike once recovered. However, the durability of the frame can be affected where the security code has been etched or stamped on. CUBE assumes no liability for any damage to material or defects occurring as a result of obtaining a security code.

Q: Can I retrofit an electric motor to my bike?

A: Electric motors place additional stress on our bikes that they are not designed to cope with. We therefore do not authorise the retrofitting of an electric motor!

Q: What should I be careful of when using and taking care of the battery pack on my hybrid?

A: Manufacturer information: https://www.bosch-ebike.com. The eBike PowerPack guide of our Partner Bosch informs you about everything you need to know about your Hybrid battery:

Q: Why is my bike heavier than stated in the catalogue?

A: It is not always possible to realise the exact weight for each bike, size and component. Our stated figures refer to the smallest frame size without pedals.

Even in the same frame size, weights can vary considerably. This can be caused by variations in the thickness of frame material, longer welds, longer brake lines / shift cables / outer casings, etc…

 

Components can also be a cause of weight fluctuations – this applies particularly to tyres.

For each frame size you should allow for up to 250g – 300g additional weight due to these variations. We always try to publish accurate weight data. The best way to eliminate all variables and make up your own mind is to visit your local dealer and weigh your dream CUBE bike in the shop yourself.

Frequently asked questions answered by Cube partner Bosch:

Q: What is special about lithium-ion batteries?

A: Lithium-ion batteries are among the most up-to-date and common e-Bike batteries around. Thanks to their high energy density they can store more energy and are relatively light in weight. We rely on lithium-ion technology for all of our Bosch e-Bike batteries – our PowerPacks. Bosch batteries weigh about 5.5 lbs (2.5 kg) and are among the lightest on the market. They also have the highest energy density.

Q: How long does a battery last?

A: Lithium-ion batteries are not only light; they also have a long service life. Bosch PowerPacks are designed for many tours, distances and years of use. The smart electronic Bosch battery management system protects lithium-ion batteries from too high of temperatures, overloading and deep discharging. A precise life span is impossible to forecast, however. The battery’s service life will depend mainly on the nature and duration of the stress to which it is subjected.

Q: How can you influence the service life?

A: To get the longest service life out of a battery e-Bikers need only to follow a few simple rules in respect of protection, transport and storage. They include storing the battery in a dry environment and protecting it from direct sunlight at a room temperature of around 59°F (15°C) to 68°F (20°C). The ideal charging level for a battery is between 30% and 60%. Ideally, the battery should be recharged at room temperature. When transporting an e-Bike it is important to remove the battery from the bike and store it safely in the car.

Q: How long does it take to charge a battery?

A: The charging time depends on the battery’s capacity. Using the standard charger (for a half charge) the PowerPack 400 takes about 1.5 hours and the PowerPack 500 roughly 2 hours. A totally depleted PowerPack 400 takes 3.5 and a PowerPack 500 roughly 4.5 hours.

Q: How far can you travel on one battery? And which factors affect the battery’s range?

A: For many e-Bikers these are crucial questions to which there are, however, no generally valid answers. The answer can differ enormously – from less than 12 miles (20 km) to well over 62 miles (100 km) on a full battery charge. Many different factors affect the range. They include the assistance level, cycling behavior, air resistance, the cyclist’s weight, tire pressure and, of course, the terrain. What are the ground conditions? Am I cycling on a paved road, a farm track or a forest trail? Does my route include ascents or consist solely of flat and open country? All these factors influence the battery range. If you are planning a tour, a visit to www.bosch-ebike.com is highly recommended. The website includes a range assistant that takes the different factors into account and gives you an idea of how far you can expect to travel in the conditions that you specify.

Q: What precautions should be taken in winter?

A: A general rule is that cold weather reduces battery performance. That is why, in winter at below-zero temperatures, it is advisable to wait until just before you set out before attaching to your e-Bike a battery that has been charged and stored at room temperature. If you have not used the e-Bike for quite a while – in winter, for example – the battery should be stored in an environment that is dry and cool at about 30% to 60% of its charge capacity.

Q: What must be kept in mind when cleaning the battery?

A:  A pressure washer is unsuitable for cleaning an e-Bike, especially its electronic components. We recommend wiping the battery with a damp cloth. Do not use strong detergents that might affect the surface and always remove the battery before cleaning the e-Bike. Its plug connectors should also be cleaned and lightly greased from time to time.

Q: How are batteries best charged?

A: PowerPacks with lithium-ion cells can be charged for as short a period as you like irrespective of their charge status. The PowerPack’s integrated battery management system, combined with a Bosch charger, protects the battery from overload when charging. Interrupting the charging process does the battery no harm. An important point to bear in mind is that e-Bike batteries should only be charged with the right charger because irreparable damage might otherwise result and warranty or guarantee claims might become invalid.
