As the mountain bike continues to evolve, we take the best of the new technologies and apply the unique experience of CUBE's engineering team to create something special. The result, in this case, is the Stereo Hybrid HPA 120 Race 27.5+. It's a bike that blends powerful Bosch e-bike technology with the smooth rolling of 27.5+ wheel to create a versatile all-rounder. Mountain biking has never been this much fun.
The Bosch drive system, 120mm of travel and plus sized tires all have their own specific requirements. That's why we crafted the chassis using all our experience and know-how, to create a structure that's stiff, light and strong. With Boost hubs to increase steering and tracking precision, complex hydroformed tubes and the unique combination of our proprietary Agile Ride Geometry and Efficient Trail Control kinematics, you can be assured of a bike that will do exactly what you ask for it.
An e-MTB is only as good as its power unit, which is why we opted for Bosch's peerless CX system. With up to 75Nm of torque on tap and a 500Wh battery for hours of stress-free riding, there's simply no better option. Tough, light, grippy and comfortable Schwalbe Nobby Nic tyres in a width of 2.8in ensure that no trail is too tough, while we specced a custom combination of Magura MT5 and MT4 hydraulic discs so that you're always in control. A blend of Shimano's reliable, smooth-shifting SLX and XT transmission components mean that the right gear is only ever a click away, and a Fox Float rear shock and Suntour Raidon fork keep both wheels planted firmly on the trail.
e-Bikes come in as many shapes and sizes as non-powered bikes, so you can have an electric road bike, mountain bike, city bike or general hybrid style. But, there are extra choices for you to make as well, so this is a brief guide to choosing the e-Bike best suited to your needs. For a more complete guide, please visit our Blog post on Choosing Your e-Bike.
Frame design
The primary choice is whether there is a top tube or you have a step-through frame. If you have any limitations in your hip flexibility and find it hard to raise your leg around the back wheel and saddle, then a step-through frame will be the better option for you. Given e-Bikes are heavier than other bikes, a step-through is also easier to handle if you're not very strong.
Battery power & capacity
"How far can I go between charges?" is the most common question, and the answer is "It depends", but here are some useful guidelines. Firstly, you control how quickly you deplete the battery. e-Bikes have power assist settings that you use to control acceleration and the amount of assist. If you choose "economy", it will take longer to get up to speed, and your top-end speed will be lower than if you select "turbo" mode. In addition, most e-Bikes are pedal assist, so you need to turn the pedals, and the more force you put in, the less you consume the battery charge. Finally, hills consume more power than flats, so your route selection makes a difference.
Batteries are rated in Watt hours (WH), and you can use this to compare the expected range between bikes. You simply multiply the voltage (V) by the amp hours (Ah) to calculate the Watt hours. On average, if you didn't pedal at all, each mile of flat travel will consume 15 WH. The e-Bikes we sell all have batteries with 300 - 400 WH, so that is 20 - 27 miles on a flat road with no pedaling.
Motor location and drive system
There are three primary positions for the drive system, the front wheel, the rear wheel and the crankset (to which the pedals are attached). By far the best is the crankset, as it is the most efficient, and it keeps the centre of gravity low. Motors in the wheel hubs are more common, as they are less expensive, and there are offsetting pros & cons for front versus rear wheel. drive.
Throttle or Pedal-assist
Our FreeGo e-Bikes have a throttle, so you can choose to be powered exclusively by the electric motor. Our other e-Bikes are all pedal-assist, which means the motor amplifies your own pedaling. The amount of power added by the electric motor in all cases is controlled by the setting, for example "economy" or "turbo".
