For more than 10 years, Bosch eBike Systems has been delivering innovative eBike drive systems that offer the best performance and quality. A large number of awards and test wins confirm this and make us proud to pursue our daily work.

Careful on putting pressure on that LED face as you are removing and installing the batteries! Probably best of you use your left thumb on the edge of the purion case & your other 4 fingers on the opposite side, avoiding squeezing onto the face and possibly damaging the led"s.

Other than the simple battery voltage check at the purion and a check for connection tightness, looks like this could be a warranty issue. I wish you the best and hope you get the bike up and running soon!

2. Bosch mid drive motor is provides power very naturally. You get the feeling that the motor is helping you pedal. Unlike hub motor bikes where you feel the motor is pulling you along.

You may purchase the Purion to replace your own lost or damaged Purion, or to replace the the Intuvia display that came with your Bosch eBike. Please contact us for installation details.

All basic information at the click of a thumb: The new Purion on-board computer operates with maximum efficiency and precision. The display clearly shows the most important information.

This article will shed light on where each motor from the four main manufacturers (Bosch, Brose/Specialized, Shimano, Yamaha/Specialized) performs best – and where they falter.

Bosch’s Performance Line CX equals Shimano’s torque, also delivering 85Nm, but only offers 340 per cent support. Bosch wasn’t able to disclose the Performance Line CX’s peak power.

Bosch’s Performance Line CX motor has four stock modes, but depending on which control unit is fitted, the trail mode functions differently. For Purion-equipped bikes it has eco, trail, eMTB and turbo. Kiox 300 bikes have eco, trail+, eMTB and turbo.

Bosch’s eMTB and trail+ modes are reactive to rider input, where torque and power assistance levels are altered on the fly depending on how hard a rider is pedalling.

Finally, the Giant motor has five modes: eco, tour, active, sport and power. The active mode functions similarly to Bosch’s trail+ and eMTB modes, where increased rider input increases the amount of motor assistance.

The Bosch motor is only compatible with Bosch batteries. The range starts with a 300Wh unit and increases to the headlining 1,250Wh battery. This makes it one of the biggest-capacity batteries.

Unlike Bosch, Shimano’s EP8 motor can be paired with third-party batteries. Shimano has its own 504Wh and 630Wh units, too. SL ebikes such as the Orbea Rise use a 360Wh unit, while Norco’s Range VLT with EP8 motor can be paired with a 900Wh battery capacity.

Given batteries can weigh from 3,150g (Shimano BT-E8035) up to 4,500g (Norco VLT 900Wh) depending on their capacity, the relatively small difference in weight between the Shimano and Bosch motors isn’t a particularly significant factor.

The Shimano EP8 and Bosch Performance Line CX motors both have bar-mounted displays, while the Giant and Specialized’s displays are built into the bike’s top tube.

The Shimano display has several variants, including ones with monochrome and full-colour displays. Shimano’s controller has two buttons and sits next to either the left-hand or right-hand grips.

Bosch produces a vast range of displays with varying functionality. The most basic is the Purion model, which even lacks smartphone connectivity. At the other end of the scale is the Nyon display that features touchscreen functionality. The model of display dictates which controller is installed.

Giant’s RideControl Go top tube display uses sequential LED lights to indicate remaining battery charge and which mode the bike is in. The redesigned RideControl Ergo 3 controller has three buttons and can be installed on either the left- or right-hand side of the bars, and button functionality is configurable using the app.

The Specialized MasterMind TCU, like the Giant’s display, is mounted to the bike’s top tube. The top-spec version features an in-built colour LCD display with customisable data fields.

The less sophisticated TCU uses LED lights to denote battery charge and selected mode, but both displays use the same four-button bar-mounted controller.

Shimano’s E-Tube Project app permits mode customisation and can turn your smartphone into a display screen for live ride data, if you’re using a bike phone mount.

The Bosch Flow app (which is one of multiple Bosch ebike apps, where each one is compatible with different head units and motor systems) can be used to tune motor outputs and plan and track rides.

Bosch’s Performance Line CX feels like the most powerful motor out on the trail, especially in its eMTB and turbo modes. The power it provides is addictive, constant and feels as though it matches and augments rider pedalling inputs with total cohesion.

In contrast, the Shimano EP8 feels as if it has less power than the Bosch in its maximum boost mode. At times, it feels as if it throttles back on power, especially when you pedal harder on steeper or faster ascents. This can be a bit frustrating when you’re expecting its assistance to back up the effort you’re putting into the pedals.

In this window, it’s well matched to the Bosch in terms of power despite its headline figures being marginally higher. Each pedal stroke, especially at lower cadences, is harmonised with and augmented by the motor, where more rider input equates to a satisfying boost in assistance.

Unlike the Bosch, which keeps on providing assistance up to the limit, its power tapers down towards the very top end in a similar way to the Shimano EP8.

Impressively, the Bosch’s power delivery is progressive despite it feeling like the most powerful motor out on the trails. The power increase tapers up, and is matched to how hard a rider pedals regardless of mode. This makes hard starts on steep or technical sections relatively easy.

Massive amounts of low-cadence, easy-to-control grunt augments this further. The Bosch doesn’t need hard pedal strokes to provide assistance, where light pushes of the pedals turn the back wheel slowly but with plenty of torque. It behaves in the same way a low-range gearbox does on an off-road vehicle, improving traction and control massively.

The Bosch motor also tapers down its power rather than stopping it instantly. This makes it much easier to adjust pedal timing in rocky sections or briefly hop up a step without being left with no assistance.

The Bosch’s battery life was affected by multiple factors. On a Purion-equipped bike with DoubleDown casing, MaxxGrip Maxxis tyres in eco mode, more than 2,000m of climbing was regularly achievable, even in terrible weather conditions.

Finally, based on my testing, the Giant’s motor isn’t particularly efficient compared to the other three. It was possible to crack only 1,500m of climbing on a single charge in the lower assistance modes despite its battery being almost identical in size to both the Shimano and Bosch bikes in this test.

The Bosch makes a more constant whining sound with a higher pitch than the EP8 and Yamaha motors. This sound makes it easier to tune out compared to the Giant and Shimano motors, but it’s arguably marginally louder.

The Specialized/Brose motor has a lower-pitched whine that, like the Bosch, is constant. It’s also quite loud, but because of the more constant pitch, it’s much easier to ignore than the EP8 or Yamaha.

The Yamaha/Giant unit has a tapping, higher-pitch knock. This is more noticeable than the Bosch – mostly thanks to its pitch – but can also be felt through the pedals.

Care and maintenance aside, one of the most frustrating things about living with certain ebikes is the lack of an accurate battery percentage display. The on-bike Bosch Purion and Shimano EP8 displays, and the Giant and Specialized’s basic TCU LED indicators, all show battery charge in 20 per cent increments.

Bosch’s Kiox 300 and the Specialized MasterMind TCU display show accurate battery life percentages. This feature is a great addition, and for bikes with smart LCD displays (such as the EP8), maybe a future software update could include this functionality.

For me, it’s a close call between the Shimano EP8 and Bosch Performance Line CX systems because both motors offer plenty of power and good battery life. You’ll also have the greatest choice of bikes, given Shimano and Bosch motors are most commonly specced.

By saying that, I’m not suggesting Giant and Specialized bikes are bad. In fact, quite the opposite is true, and I declared the S-Works Turbo Levo the best bike I’ve ever ridden, but as a consumer if you want a Brose or Yamaha motor, you’re limited to a smaller number of bikes that may or may not suit your needs compared to their Shimano or Bosch counterparts.

In a perfect world, I’d meld together the natural-feeling assistance of the Brose, the battery life of the Shimano and the outright power of the Bosch, coupled with Specialized’s discreet MasterMind TCU and Giant’s RideControl Ergo 3 control buttons.

Frequently mounted to the handlebars near the grips, the controller’s buttons change between each of the bike’s modes and can cycle the display, if one is fitted.

Sometimes this is fitted to the handlebars or stem, but it can also be integrated into the bike’s top tube or elsewhere. It can display multiple bits of useful information, including battery charge and current selected mode, along with speed, range and cadence.

Most motors feature user-programmable or selectable support levels. The mode types change the amount of power and torque assistance a motor will provide. For example, Shimano’s lowest-power mode is called ‘eco’, while Bosch and Specialized’s highest setting is called ‘turbo’.

The Bosch Purion is a minimalist on-board computer designed for anyone who wishes to focus on the most important information and prefers an uncluttered handlebar. The Purion displays the essentials and lets riders get all important information with a click of the thumb, while keeping hands on the handlebars. Five different riding modes provide just the right amount of assistance in every situation.
