Cube Reaction Hybrid SLT 625 29er Electric Bike 2020 Black/Grey

Season : 2020

Brand : Cube

Code : 33440219-CUBE20

The Cube Reaction Hybrid SLT 29er Mountain Bike, completely redesigned for 2020, is currently the benchmark of all things in aluminum e-mountain bike technology. That's not the only reason why Cube are particularly proud of this SLT offshoot of there Bosch e-bike family. Why? Its pleasing, elegant looks are home to a wealth of clever design solutions and technical refinements, and the features are the same as any bike lover's wish list. A key role in the perfectly matched e-bike orchestra is played by the new CUBE Modular Battery System, which enables the use of a new, even more powerful battery. This disappears completely in the specially developed Gravity Cast down tube, where it is safely protected from dust, dirt and water. The new engine case provides a sturdy and secure platform for the fourth-generation Bosch engine, while the boost rear, oversized chainstays and a stiff 1.5 inch head tube transfer its even and virtually noiseless power to the rear wheel most efficiently. A retractable seatpost can be easily retrofitted when needed, and the redesigned Agile Ride Geometry and the chain stay guard with integrated cable guide are the icing on the cake. Of course, all our SLT models can only be as good as the components that are built into them - and again, only the best was good enough for the Reaction Hybrid SLT. The Fox 34 Rhythm suspension fork, together with the 2.6 inch Schwalbe tires, offers 120 mm finest riding comfort on the trail, while the XT and SLX components of the new Shimano 12-speed gearbox promise smooth-running and reliable gear changes with optimum bandwidth. And the powerful hydraulic Shimano disc brakes with extra-large 203 mm rotor at the front give you the braking power you need on demanding tracks - regardless of the weather. With this bike you can master every challenge!

Cube Reaction Hybrid SLT 625 Highlights

  • Superlite Aluminium, advanced hydroformed frame
  • Fox 34 Rhythm Suspension Fork with 120mm Travel
  • Bosch Powertube 625
  • Bosch Drive Unit Performance CX Generation 4 250 Watt 75nm
  • Bosch Kiox Display Unit

The target for the all-new Reaction Hybrid 29 was as simple as it was sophisticated: our engineers wanted to design the ultimate e-bike hardtail frame. Mission succeeded! The basis is the ingenious Modular Battery System, which makes the Bosch battery completely disappear in the new Gravity Cast down tube and under an easily accessible cover. This not only looks great, it also leaves enough space for a bottle cage - or the use of a larger battery for even more range. It continues with Oversized chainstays, a boost rear suspension and a 1.5 inch head tube, which in perfect teamwork transmit the uniform and powerful power of the Bosch engine to the rear wheel. Our proven Agile Ride Geometry has been redesigned and perfectly matched to the 120 mm suspension fork. This results in a handling that is as trustworthy as it is lively. The internally routed trains - a retrofit with a retractable seatpost is easily possible - provide a tidy look, and with the trapeze version, we really serve every taste.

Sizing Information

How To Measure Yourself

Measure Your Height

Our handy size charts match your height to the appropriate frame size so you need to be sure you’ve measured your height accurately.

  1. Take off your shoes and stand with your back against a wall.
  2. Make sure legs are together and your shoulders are back.
  3. Place a pencil on top of your head and mark the wall (the best and easiest way to do this properly is with a friend to help you).
  4. Measure from the floor to the pencil mark you have just made with a tape measure.

Range of Reach

For most people to get the right frame size, measuring your height will suffice. However, you may find that your height is on the borderline of the range we suggest for a particular frame. If this occurs you need to measure the range of your reach or “Ape Index”. This will ensure you get a comfortable distance between the handlebars and your saddle.

  1. Stand up straight with your back against a wall.
  2. Life your arms out horizontally either side of you.
  3. Measure the distance from fingertip of one hand to fingertip of the other. This will give you your arm span.
  4. Subtract your height from this figure to get your Ape Index.
  5. If the result is positive (your arm span is greater than your height) you should go for the larger size of bike.
  6. If the result is negative (your arm span is less than your height you need the smaller size.

Stand Over Height

You should also consider your inside leg measurement when choosing your bike to ensure adequate stand over height. Stand over height is the clearance between the top tube and the bottom of your crotch. For mountain bikes we recommend a distance of 2-4 inches and for road or hybrid bikes 1-2 inches of clearance is required. This will ensure comfort when you’re stopped and standing astride the bike.

Our bike sizing charts take stand over height into consideration but if you have a particularly long or short inside leg measurement in relation to your height you will need to bear this in mind when selecting your frame size.

Riding Style

The way you ride and the type of bike you are into will also impact the frame size you should choose. For example, a trail devotee looking for an aggressive ride may prefer a smaller, more manoeuvrable bike size. It all comes down to personal preference and how the bike feels to you.

Our sizing charts aim to be as specific as possible so you can look up the particular type, make and model of bike you’re looking for. Remember, the sizes given in our guides are suggestions and should be used for general advice only. For the best possible fit  we recommend popping in to your local Leisure Lakes Bikes store, or call 0800 083 0888 for expert advice tailored to you.
