CUBE Fold Hybrid

Cube calls the frame construction Integrated Folding Technology. The central hinge is located in the main frame and splits the bike into two compact halves when folded. In addition, there is a folding stem and folding pedals. The seat post and handlebars can be lowered so that the folded bike takes up less space. A carrying handle positioned in the frame area provides a defined point for lifting.

The packed dimensions are approximately 90 cm in height, 60 cm in width, and 75 cm in length. These values apply to the current Fold Hybrid and Fold Hybrid Comfort models in One Size. Before purchasing, it is worth measuring the intended storage space. In the trunk, it is not just the pure volume that counts. The loading sill, opening width, and the shape of the back seat can determine whether the bike can be loaded comfortably.

For the folding process, you should choose a level surface and first remove any luggage from the bike. Then, lower the seat post, fold down the stem, and release the frame joint in accordance with the owner's manual. When opening, all latches must click fully into place. A mechanism that is only partially closed must not be put under load.

The carrying handle is primarily intended for short distances, such as from the platform edge to the luggage area or from the front door to the car. Weighing over 25 kg, the bike remains heavy. Keep it close to your body when lifting and use both hands when navigating stairs or high loading edges. Removing the battery reduces the weight to be lifted and prevents the battery from being unintentionally stressed during loading.

For the daily switch between bike and train, a fixed routine is helpful. First, adjust the saddle and handlebars to your riding position and mark the appropriate height discreetly. This way, you can find the setting more quickly after every train ride. A transport bag protects other luggage from dirt. It also prevents pedals or handlebars from bumping into trim in the car.

The folded size makes the Cube more compact than a standard e-bike, but not as small as a lightweight folding bike without a motor. Specifically, the width of about 60 cm and height of about 90 cm can be significant in crowded trains or small cars. If regular transport is the main reason for your purchase, you should try the folded bike in your vehicle or a comparable storage space beforehand.

The 75 Nm of torque assists with quick acceleration and helps on inclines, against headwinds, or with extra luggage. The mid-drive motor transfers its power through the bicycle's drivetrain. This keeps the handling predictable, and the weight is positioned centrally in the bike. Assistance ends at 25 km/h in accordance with pedelec regulations.

The Bosch Smart System connects the motor, battery, and Purion 200. Via the eBike Flow app, you can, among other things, retrieve ride data and manage available system functions. Depending on the release and software version, riding modes can be customized. Strong assistance and high dynamics increase energy consumption. Those who need more range should ride on flat sections with lower assistance and shift into an appropriate gear early.

For a Cube Fold Hybrid 500, a range of about 50 to 80 km per battery charge is often realistic in mixed city traffic. This range is not a fixed guarantee from the manufacturer. The actual range varies based on the support level, rider weight, luggage, outside temperature, tire pressure, inclines, and the number of stops and starts.

On a flat commute with a high level of rider input, a 500 Wh battery can also cover longer distances. Numerous inclines, low temperatures, and frequent acceleration in the highest mode reduce the range. The PowerPack 545 has about nine percent more nominal capacity than a 500 Wh battery. Under comparable conditions, this results in a corresponding advantage in range, not automatically a specific additional number of kilometers.

• Check your tire pressure regularly, as soft tires increase rolling resistance.
• Use a low assistance level on flat sections.
• Shift into a lower gear before an incline.
• Store and charge the battery in a temperature-controlled room whenever possible when outside temperatures are low.
• Plan for a buffer on unfamiliar routes instead of using the entire calculated range.

The PowerPack is located behind the seat tube. It can be removed for charging, meaning no power outlet is required directly at the parking space. This is practical in rented apartments, offices, and shared bicycle storage rooms. A lock secures the battery to the bike. After unlocking, it is removed from its mount and connected to the appropriate Bosch charger.

Alternatively, the battery can be charged on the bike if a suitable power outlet is available at the parking space. Before every ride, you should check that the battery is fully inserted and locked. When transporting in a car, it is recommended to store the battery separately and secured against slipping.

The One Size Concept replaces the choice of multiple classic frame sizes. For the Fold Hybrid, Cube specifies a recommended height range of approximately 1.60 m to 1.90 m. This is made possible by the extendable telescopic seat post and the height-adjustable, foldable stem. The low step-through makes mounting easier and suits its use as a city and commuter bike.

• The telescopic seat post can be extended significantly and lowered for shorter individuals.
• The stem can be adjusted in height and folded down for transport.
• Quick-release levers allow for adjustments without additional tools.
• The low frame makes frequent mounting and dismounting in city traffic easier.

If several people use the e-folding bike, the respective settings should be known. Small markings on the seat post and stem save time without compromising the secure clamping. After every adjustment, the quick-release levers must be firmly closed. The seat post must not be extended beyond its maximum extension mark.

The specified height range is a guide. Body proportions vary. Two people of the same height may require a different seating position due to different leg and torso lengths. At a height of 1.90 m, you should therefore check whether your knees, hips, and back remain comfortably positioned during a longer test ride. The decisive factor is not just whether the saddle can be set high enough.

As a starting point for saddle height: the leg should be almost fully extended at the lowest pedal position, without the pelvis tilting sideways while pedaling. The handlebars may be positioned high enough to allow for an upright posture, ensuring both brake levers are safely within reach. If you switch between two significantly different settings, check the alignment of the handlebars before setting off.

The One Size Concept is particularly useful when partners or family members share a bike. It also simplifies future resale, as there is no need to look for a rare frame size. However, anyone expecting a very sporty, forward-leaning seating position should check whether the upright basic geometry suits their desired riding style.

When comparing, the model year must first be clarified. The Cube Fold Sport Hybrid 500 belongs to an older model generation. It was offered with a Bosch Active Line Plus, 500 Wh battery, and a Shimano Tiagra 10-speed derailleur gear system. The standard Fold Hybrid 500 version at the time, on the other hand, used a Bosch Performance Line with 65 Nm and, depending on the version, a low-maintenance hub gear with a belt drive.

In the current model series, the Fold Hybrid 545 with a Shimano Cues 9-speed derailleur largely takes on the role of a direct, wide-range version. The Fold Hybrid Comfort 545 features a Shimano Nexus 5-speed hub gear and a Gates carbon belt. Both current versions are equipped with the Bosch Performance Line motor with 75 Nm and a PowerPack 545.

If you are looking for a bike that requires as little maintenance as possible for your daily commute, the Fold Hybrid Comfort 545 is a great fit. The toothed belt requires no chain oil and causes less mess on clothing or transport bags. The internal gear hub can be shifted while at a standstill, which is convenient at traffic lights. Its five gears are sufficient for typical city routes, though they may feel more widely spaced on varied terrain.

If you frequently ride on inclines or prefer finer gear increments, the Fold Hybrid 545 with nine gears offers more variety. The derailleur gears respond directly and can be maintained with standard components when they wear out. However, the chain requires regular care. After riding in the rain or long periods of transport, it should be cleaned and re-lubricated as needed.

The older Fold Sport Hybrid 500 is primarily of interest on the second-hand market. Its name suggests a fundamentally more powerful motor, but the installed Active Line Plus delivers 50 Nm. The current Fold Hybrid 545 is significantly more powerful with 75 Nm. The "Sport" designation is also not a reliable indicator regarding weight: The Fold Sport Hybrid 500 was specified at approximately 25.9 kg and was therefore no lighter than the current versions.

Therefore, when considering a specific offer, check the motor, battery, gears, and model year individually. The model names have been used over several generations, while the technical specifications have changed.
