Cube Stereo Hybrid 140 HPC Pro Bike Review

Cube Stereo Hybrid 140 HPC Pro Bike

With its sleek integrated battery, at a glance you’d be hard-pressed to tell that the Cube Stereo Hybrid 140 was an e-bike. Mounting the battery inside the down tube not only protects it from water and dirt, but it can also lower the center of gravity by getting the heaviest bit of the bike lower down in the frame.

This can add stability and improve the overall handling. An added bonus on the Stereo Hybrid 140 Pro is it also frees up space for a bottle cage, which we reckon is dead handy for hot summer rides. Powering the Stereo Hybrid 140 Pro is the Bosch Performance CX drive unit. This has four ride modes; Eco, Tour, eMTB and Turbo. And while Turbo sounds the most exciting, it’s actually eMTB that’s the most impressive, as this automatically adjusts the amount of assistance, which simply means, the harder or faster you pedal, the more it helps you.

The Purion control unit is neat and simple, with a small display giving you everything from remaining range to current mode, and it’s backlit for night rides.

Bosch uses a mini sprocket to power the drivetrain, and this boasts loads of mud clearance around it, making it much easier to keep clean in the winter. Taking care of the shifting is an 11-speed Shimano transmission, which is incredibly smooth and offers plenty of range. To improve shifting performance the driveside dropout features an Adaptable Syntace X12 hanger that’s specifically designed not to damage the frame if you drop the bike on its side.

Suntour provides the suspension for the Stereo Hybrid 140 Pro and both ends get 140mm travel. Cube has revised the suspension kinematics to be a bit more progressive this year, so there’s a bit more support. Cube has also added some length to the bike, making it more sure-footed when the trails take a turn for the worse.

With its new eMTB function the Stereo Hybrid 140 Pro has a super smooth power delivery, and combined with the chunky Schwalbe tyres, makes it easy to maintain traction on steep, slippery climbs. This do-it-all option also allows you to manage the battery life much more effectively. The Stereo Hybrid 140 Pro has some fine details, but the best thing has to be the price — at $4,000 it’s a great first step on the full-suspension e-MTB ladder.
