We first spotted the Stereo Hybrid 120 HPC TM 500 at a Cube product launch at its headquarters during the summer in 2018. The carbon fibre main frame, with its fully-integrated battery, is particularly noticeable. At the heart of this machine is a powerful Bosch Performance CX motor, along with capable Fox suspension. 130 mm travel up front and 120 mm at the back together with solid 29” wheels promise an E-Trailbike with both up- and downhill prowess. The “TM” moniker indicates that this E-Bike has been equipped according to Cube’s Trail Motion philosophy. That means you’ll find only functional, quality components fitted here. Shifting and braking are taken care of by a Shimano XT groupset, the Cube EX30 rims are shod with 29” x 2.6 Schwalbe Hans Dampf tyres and the saddle is a Natural Fit Active Race item.

The product managers at Cube have given this model the “TM” moniker. We had a chat with Michael, from Cube about what that means.

“The Trail Motion models, identified by their TM insignia, can be defined, so to speak, as the favourite bikes of our product managers. Maximum fun at a reasonable price is of clear importance here. The Stereo Hybrid 120 HPC TM is the complete package and it basically speaks for itself: a slim carbon main frame with an integrated Bosch PowerTube battery, 29” wheels, grippy tyres, 130 mm travel up front, a dropper post, powerful Shimano XT brakes and a short Newmen cockpit. It doesn’t matter whether you’re a beginner or a pro, everyone will feel immediately at home on the Stereo Hybrid 120 HPC TM. And that’s exactly what I think E-Mountainbiking is about: fun for everyone!” – Michael Grosse-Hering, Product manager for Cube

The suspension is provided by Fox – a Fox 34 Float fork paired with a Fox Float DPS EVOL shock – with 130 mm travel up front and 120 mm at the rear. The shifters, drivetrain and brakes come from the Shimano XT groupset. That promises smooth shifting and excellent durability.

Motor & Battery

Cube uses Bosch motors exclusively in its E-Mountainbikes. The Stereo Hybrid 120 HPC TM 500 is fitted with a Bosch Performance CX model. This motor is probably the most commonly found on E-Mountainbikes today and with good reason. With a maximum torque of 75 Nm, for a long time it was the benchmark to beat and it still ranks amongst the top five motors on the market for power. A unique feature of the motor is the tiny chainring, that turns 2.5-times as fast as you are pedalling. That means a 16-tooth chainring corresponds to approximately a 40-tooth in ‘pedalling terms’. That 75 Nm provides a decent push along the trail, with excellent acceleration out of corners and a purposeful feel up the hills. Sadly, above the 25 km/h assistance limit the motor reaches its limits, it provides noticeable more resistance to pedalling compared with some of its competitors.

The Cube Stereo Hybrid 120 TM is driven by the powerful Bosch Performance CX motor
# The Cube Stereo Hybrid 120 TM is driven by the powerful Bosch Performance CX motor - the progressive eMTB mode provides capable assistance and that typical E-Bike feeling
A fully integrated battery
# A fully integrated battery - the engineers at Cube have integrated the Bosch Powertube 500 battery completely into the down tube of the sleek carbon frame

Integration and a slim look were very important for the Cube engineers here, so the battery has been fully integrated into the carbon down tube. It is protected by a removable cover and when required, you can simply pull the battery out of the bottom of the down tube.

The motor has four assistance levels. Along with the standard ECO, Tour and Turbo mode, Bosch provides the brilliant eMTB mode. This progressive mode varies the power output based on how hard you are pedalling and how much effort you are putting in. The eMTB mode ranges from the 120% assistance of Tour mode to the 300% assistance of Turbo mode. That large dynamic range makes it suitable for most everyday riding, without having to constantly change assistance modes. The motor is also very good at detecting changes in rider input and adjusting the corresponding power output from the motor effectively. On steep uphills, you get the full brunt of the motor power when you pedal hard, and on flatter sections, the motor dials it down when you’re cruising along. Overall that provides a system that allows you to ride with grip, traction and the right support from the motor at all times — Bosch marketing speak calls it “Optimized Trail Control”, we would say the E-Bike responds perfectly to your pedalling input.

This model we rode is fitted with the Bosch Purion display, but it is also available with the smart Bosch Kiox display. The price difference is € 100.

Real-world range

# Cube Stereo Hybrid 120 HPC TM - range test - 38,27 km | 827 metres vertical | 1 hour37 min

38,2 km / 827 metres vertical ascent
1 h 37 min

Quoted figures for range tend to be on the optimistic side so we like to test bikes for ourselves, draining a whole battery and seeing how far the bike will go. For this test we managed 38.2 km and 827 metres of ascending, staying in the highest power setting throughout. Please note that these values in no way represent rigorous or normalised testing. Instead, they should be seen as ballpark figures. Using lower assistance modes increases the range significantly too.

On the Trail


Wow! This thing just wants to climb!

We were a little perplexed looking at the geometry of this bike. 490 mm chainstays and a steep 68-degree head angle? Will that even work? We have to say straight away: it worked very well because out riding the Cube Stereo Hybrid 120 HPC TM revealed itself as a capable climber. No climb too long and no incline too steep. The geometry and riding position allowed us to get up pretty much any trail we wanted. The Bosch Performance CX motor always offered enough assistance to help us up. However, tight and technical sections aren’t this E-MTB’s forte, as the large 29” wheels can feel a little awkward. However, in 95% of cases, this E-Trailbike offers up capable climbing credentials.

Steep uphill sections?
# Steep uphill sections? - no problem with this E-MTB thanks to the central position and long chainstays. The powerful motor simply slings you up the hill.


It’s obvious, that an E-Trailbike with 130/120 mm travel will never be a downhill king, but nonetheless, it should be able to make its way down anything with composure. This model didn’t disappoint, with only a few missteps on the steepest and roughest sections. The supportive suspension is sensitive and swallows the bumps, though the 120 mm travel rear does reach its limits. However, even when things got a bit wilder the well-mannered handling of the E-Trailbike kept us calm and we were never clinging on for dear life. The E-Bike remained comfortable on high-speed sections too, with the 29”-wheels offering excellent stability and control.

The large wheels provide a lot of stability

Well balanced and agile trail blasting!

On the trail this E-Bike reveals its true qualities with a fun and stable ride. The Bosch Performance CX motor helps us sprint up small inclines while the bike surfs along flowing trails and remains secure over roots and rocks. Tight and twisting trails require a little more practice and will likely always remain more challenging aboard this 29”-wheeled E-Trailbike. Overall though, the TM philosophy results in a package that delivers a whole lot of riding fun. We particularly like the 2.6” Schwalbe Hans Dampf tyres, which never seemed to lose grip and remain reliable even in the most challenging situations.

This E-Mountainbike feels very happy out on the trail
# This E-Mountainbike feels very happy out on the trail - the TM philosophy works well and results in a very fun ride

We noticed:

180 mm rotors at the rear
# 180 mm rotors at the rear - we would recommend fitting 200 mm rotors on all E-MTBs
SDG Slater grips
# SDG Slater grips - these slim grips are quite hard and don't provide all that much comfort
  • 180 mm rotors at the rear: E-Mountainbikes need 200 mm rotors at the front and back. The improved performance more than compensates for the few additional grams.
  • Hard grips: The SDG Slater grips offer a secure hold but aren’t the most comfortable. For longer rides, we would fit thicker and softer grips.

Summary: Cube Stereo Hybrid 120 HPC TM 500

The Cube Stereo Hybrid 120 HPC TM 500 is a fast and sporty E-Mountainbike. We don’t know if it’s the best E-Trailbike around, but we can say that regardless of where we rode it – on the EWS trails of Finale Ligure, around Latsch or even on our home trails – it was an absolute blast to ride and perfect for the purpose it was built for. The high-quality carbon frame is well designed and adds an extra je ne sais quoi. If you’re looking for a capable E-Trailbike at a competitive price, you should have a close look at the Cube Stereo Hybrid 120 HPC TM 500.

About the test

Please expand for details

On our test runs we usually stay in the highest assistance mode and drain the battery completely at least once. We then publish our results on our Strava account.

Our loop has everything we need to test what our E-bikes are capable of:

  • Tight uphill trails with roots, rocks and loam
  • Flat trails with small climbing sections
  • Fast and flowing downhills
  • Long gravel trails up- and downhill

E-bikes are subjected to our route multiple times to allow us to draw our conclusions.

We tested the Cube Stereo Hybrid 120 HPC TM 500  here:

  • On the trails around Bamberg, Germany, the Venosta valley and in Finale Ligure in Italy. The riding provides narrow and tight trails with rooty, rocky sections, steep and technical uphills as well as flowing downhills.
