Below is the recommended sizing for the Cube Reaction Hybrid ONE 600 2026. Here you should measure your height with your shoes off.

Please Note: Many bike brands' size guides overlap slightly. This is because small adjustments like seat position can accommodate riders who fall between sizes. When you're in this overlap zone, the choice comes down to preference: a larger size for a more stretched-out ride, or a smaller size for a more compact feel.

At MTB Monster, we help customers on a daily basis choose the right size bike for their needs. We consider your measurements, riding style, and past bikes to help recommend the best size. If you're in doubt at all or want to just confirm your thoughts please contact us and we would be glad to help.

Frame Protection in our opinion is money well spent. Your bike is an expensive investment and frame protection helps to protect your paintwork from scratches, scuffs and chips to keep your bike looking spotless for years to come. In essence, frame protection is a custom cut, self-healing frame protection film made from Lotus Pro 10 - 10.3mil thick TPU film (or similar) designed specifically for mountain bikes and electric bikes. It features a ceramic-embedded hydrophobic top coat that effectively repels water, mud, and dirt, making post-ride cleanups faster and easier. Kits are available in both gloss and matte finishes and unless specifically requested we would fit the kit to match the finish of your paintwork. Some bikes have a mixture of matte and gloss paintwork and in most cases mixed finish kits are available. The material of a frame protection kit will act as an extra layer of clear coat and can make the finish of raw carbon more prominent due to the way that the light refracts. Similarly, fitting a matte finish kit can produce a more satin finish and mean that the kit is slightly more visible than when it is installed in a gloss finish.

Currently there are 3 options available

1. Supply and fit.

Our trained and experienced mechanics can install frame protection kits here so that your Cube Reaction Hybrid ONE 600 2026 arrives fully protected and ready to ride. We recommend a 48 hour curing period to ensure that the film adheres properly to the frame, so your order will take a little longer to arrive — but it will be well worth the wait.

2. Supply Only.

If you choose to install the kit yourself, we'll provide you with the kit, instructions, and a squeegee. Just select "Supply Only" and your kit will arrive with your bike — there is no delay to dispatch with this option. There are many informative videos online to guide you through installation. We would advise watching these in advance to see if you feel confident to fit the kit. Patience is a must when it comes to installation.

3. N/A.

Choose this option if you would prefer not to have frame protection fitting.

Please note: If no frame protection kit has been designed for the bike yet, no option other than N/A will appear. However, there is a very good chance we may still be able to get one designed or custom templated to fit. If this is of interest, please contact us here and we can look into it as soon as possible.

Frame:

Cube offers a 6 year warranty on Aluminium frames and 3 years on Carbon/Aluminium frames along with a crash replacement scheme for items should you need a cost-saving replacement service following a crash.

Components fitted the bike

All components fitted to the bike are covered under warranty by the respective manufacturer which is typically two years however in some cases, this can vary and items such as suspension are subject to servicing being carried out.

Electrics

Bosch offers a 2 year warranty on the motor, battery and the ancillary parts required for the system to operate such as the display, speed sensor and wiring.

Whether or not a bike is supplied with pedals is at the discretion of the manufacturer. If you select the technical tab on any product page you will see 'pedals' as a one of the items and here it will tell you if they come as standard from the manufacturer. By reducing the number of components included with a new bike, manufacturers can minimise waste and packaging. With so many different types of pedal available it's unlikely that anything manufacturers include will suit everyone. If you require pedals and they are not listed as included in the specification of your chosen bike you can find the range that we offer here and of course if you are unsure please get in touch for some friendly advice.

Yes, all of the brands we deal with carry a large number of spare parts to support their customers. If you have purchased a bike from MTB Monster, our rider support team will work with you and the team at Cube to get you the parts you need as soon as possible.

The electric bikes that we sell at MTB Monster are completely legal to ride in the UK, both on-road and off-road. The maximum speed that an ebike can be assisted to in the UK is 15.5mph (25kph). It is easily possible to ride an ebike faster than 15.5mph but the motor will not offer any assistance beyond this point. The Cube Reaction Hybrid ONE 600 2026 is set at the maximum level of assistance permitted in the UK.

Pedal bikes with electric support up to 15.5mph (25 km/h) are regarded as equivalent to bicycles by law and therefore, do not require vehicle insurance, a registration plate or a driving license

Yes most upgrades on the Cube Reaction Hybrid ONE 600 2026 are fine, if you fancy changing the brakes, adding some blingy new grips, or maybe a change of fork, you're welcome to make these changes. However, just make sure they are both suitable & compatible with the bike.

Please note with E-bikes:

Changes in gearing or wheel size will need to be reflected in the motor programming as this can affect speed ratings, and this is where it starts to get tricky as it will require the brand's authorisation. Typically changing anything to do with the motor system of an electric bike is not recommended unless advised otherwise by the bike/motor manufacturer.

How you store the Cube Reaction Hybrid ONE 600 2026 is pivotal for maintaining its condition and ensuring the e-bike is ready to go when you are. Ebike's should be stored clean and dry in a cool environment between 10 to 20°C, with the battery level between 30-60%.

If a battery is ever stored separate to your bike, again make sure it's stored in an area without significant temperature fluctuations. Somewhere that endures extreme temperature changes – such as an outdoor shed for example.

Batteries are highly complex components and are designed to offer a long service life. The service life of the battery is influenced by several factors such as the amount of charge cycles, intensity of usage, charging practice and storage temperatures. That being said, under typical use of going out riding a few times a week, you should expect to get a couple of years of riding without any problems, as that has been our experience for 99% of the ebikes we have sold to date.

Also it's worth bearing in mind, we still have plenty of customers riding bikes purchased over 5 years ago with the original battery, and very rarely do we have customers complain about battery issues. And for peace of mind, if anything was to happen, the batteries themselves are covered by warranty for the first 2 years of use.

Lithium-Ion batteries are, provided certain precautions are met, are safe.

The high-quality lithium-ion batteries fitted to our range of e-bikes are equipped with a Battery Management System (BMS) which is continuously acting to detect potential sources of error and protects the cells from overload, undervoltage, overheating and short-circuiting.

According to the Bicycle Association there is a very low risk from un-modified legal Electric Assist Pedal Cycles (EAPCs – street-legal eBikes) if bought complete with their approved batteries and chargers, from reputable brands, sold by reputable retailers, and handled according to the manufacturer's' instructions.

All of our bike brands we sell, and the electrical componentry they use on their e-bikes, are fully regulated and adhere to the highest standards. It's also worth noting, that they are simply worlds apart in terms of safety, when compared to cheap unregulated imported e-bikes that you would find on any online auction sites.

Yes, the battery can be removed from the bike for easy charging and for safe keeping. The battery will be locked onto the frame and will require the keys supplied with the bike to fit or remove the battery.

A range extender is an additional power bank that can be connected to the bike for longer rides which the main battery capacity wouldn’t satisfy. The PowerMore 250 is compatible with the Cube Reaction Hybrid ONE 600 2026

If we have the range extender in stock, we will add a purchase link on the technical tab of the product page (next to range extender) to add to your shopping cart if required.

For fire safety, couriers have restrictions that prevent the shipping of electric bikes with more than 30% charge. This will be more than enough to take your new bike for a quick spin but the bike will require a full charge prior to your first proper ride

The battery is integrated in the downtube and is charged through the port on the frame.

The best practice is to firstly connect the charger to the charger port then plug into the wall socket. This way the charger will automatically switch on and start charging your battery when connected to the wall socket and switch off supply once the bike is fully charged therefore preventing overcharging the battery. As the battery is charged the display (if fitted) will also be charged up at the same time.

Bosch advise 6.9 hours for a full charge on a 800wh battery with a 4A charger and 2.6 hours and for a 50% charge. Whereas the 600wh battery is advised to take just over 5 hours for a full charge and 2 hours for a 50% charge.

The motor on the Cube Reaction Hybrid ONE 600 2026 is protected by a plastic guard which will shield the motor from the worst of the trail conditions and will act as a sacrificial part to protect the motor from impact should you require it.

The first step is to contact your HR department or your accountant to check that you are eligible to access a voucher and discuss any questions that you might have about how the scheme is run at your workplace.

Once you have confirmed that you are eligible for a voucher, it's best to place a £200 deposit here to reserve the bike of your choice to prevent stock from selling out while your voucher is being arranged.

You are more than welcome to place a £200 deposit to reserve the bike while you are finalizing your payment method to prevent the bike from selling out in the meantime.

We are more than happy to reserve a bike for up to 3 weeks but please let us know if you need us to reserve the bike for longer so that we can best know your situation and accommodate this.

If you want to place a £200 deposit, please fill out the options on the product page to reveal a pre-order button (see image below).
