Five different riding modes give you the correct support in every situation.

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.

For any bicycles with the Purion display, the system can be upgraded to Intuvia, Kiox or Nyon. If the bicycle is a Class 1 (20mph), it can also be upgraded to SmartPhone Hub.

For any bicycles with an Intuvia display, the system can be upgraded to Kiox or Nyon. If the bicycle does not feature e-Shift (Rohloff E-14 or enviolo AUTOMATiQ or Automatic+), it can also be replaced with a Purion display.

For bicycles with a Kiox display, the system can be upgraded under stricter conditions. If the bicycle features FOX e-Suspension, there are no alternatives. For high speed bikes (assist to 28mph), the Kiox can be replaced with a Purion, Intuvia, or Nyon; but if the bicycle features e-Shift, then only the Intuvia or Nyon are viable upgrade options.

For any bicycles with the Nyon, the system can be swapped to a Kiox or Intuvia display. If the bicycle does not feature e-Shift, then the Purion is also an option.

The odometer information is stored in the drive unit, so the total miles your bicycle has been ridden will transfer to your new display. Only if you need to replace your drive unit will your odometer be reset.

You should plan to have the display changed at a certified Bosch dealer. For most changes, it requires redoing the wiring from the display to the drive unit, rearranging many of the other controls on the handlebar, and completing a firmware update through the Bosch dealer software. For stem-mounted displays, other parts may be required as well to set your bicycle up properly.

We"ve been out in Switzerland trying out some new electric mountain bikes (more on that soon) but we also got to have a first go on Bosch"s new display, the Purion.

It"s a compact display and control head unit that isn"t much bigger than the current remote used with the Intuvia and Nyon displays, and it sits on the handlebars in the same position, by the left hand controls. There"s two mode buttons, an on/off button on the top and and a walk assist button on the bottom.

The backlit LCD display shows the battery status, and the speed at the top. In between there"s another data field. This can display power mode, range in current mode, odometer or trip distance. You can toggle between the displays with a longer press on the big minus button. If you have lights as part of your setup you can turn them on and off with a long press on the plus button, and there"s an icon on the LCD display to remind you.

The display is basic, but it tells you everything you really need to know and it"s simple to use. If the middle data field is set to anything other than the power mode, it will display the power mode briefly when you change up or down, then revert to whatever it was displaying before. The battery level indicator is a simple five bar graphic and it"s simple to understand and seems to be pretty accurate, although one of our riding party was a bit surprised to find out that with one bar of battery left you only get a few minutes of power in Turbo mode! If you want to have a more detailed idea of how long your juice will last, it"s best to be looking at the range.

My one main bugbear with the standard Bosch remote is that the plus/minus buttons are to sensitive: if you"re resting your hand on the bars and you accidentally rest your left hand against the remote then you can find yourself switching modes by accident.

The opposite is true of the Purion: You"ll never accidentally switch modes, but the plus/minus buttons are a bit fiddly: you have to get the press right, hitting the centre of the button, and the feedback, especially when you"re wearing gloves, isn"t great. More than once I found myself needing to move up to a higher mode and thinking I"d clicked the button, only to find I didn"t have any extra power. Because the mode isn"t necessarily displayed, it"s not always obvious whether you"ve changed or not.

You get wise to the way the buttons work after a while, and it became less of an issue as I got more familiar with the display. Overall it"s a useful addition to the Bosch system and it"ll appeal to anyone who wants a cleaner, more stripped back look to their electric bike and doesn"t need to be bombarded with data. Given the size of the Purion display I"m a bit surprised that the decision wasn"t made to always show the current mode, it"d be easy to do without taking much space from the rest of the data fields. A simple segmented bar along the top would do it.

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!

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 Performance Line CXBrose/Specialized Drive S Mag/Turbo Full Power System 2.2Shimano EP8Yamaha/Giant PW-X3/SyncDrive ProPeak powerUndisclosed565w500wUndisclosed

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’.

In our overview article “How to find the best e-bike app for your needs” we mentioned that the smartphone, in combination with suitable apps, is becoming increasingly important as the control centre of e-bikes. After all, it is extremely powerful and offers a wealth of options for an optimal riding experience. And the truth is that no e-bike display can keep up with that.

But the time has not yet come. If you buy an electric bike, it usually comes with a display. And just as the e-bikes differ, so do their on-board computers. But what are the most important differences, which brands and models are particularly interesting and what options do you have?

The devices are connected to the drive of your e-bike. To control them, you use a handlebar remote control, buttons on the display or the touchscreen – if there is one.

With the help of the display, you can control your e-bike and read data, for example about the route or your performance. However, this is where the main differences begin. The differences between e-bike displays are significant, both in terms of the setting options and the data that can be viewed.

Important note:It is not easy to quickly change the display on an e-bike. This is because the drive and bike computer are linked to each other. With a Bosch e-bike, you can switch between different Bosch computers. However, you cannot simply switch to a Yamaha control unit because you like it better. This means that when you buy a bike with motor assistance, you decide in favour of displays from one manufacturer.

Compact and minimalist. A display of this type is used to make basic settings on the e-bike and to read a few data such as the current speed. Many modern e-bike manufacturers rely on this variant. They assume that their customers will use a smartphone on the handlebars anyway, which would make another large display more annoying than helpful. This type of display is sometimes a control unit with LEDs without a screen.

With a display like the Bosch Kiox, you have an e-bike computer that deserves its name – at least a little bit. Such systems with all the functions – such as integrated navigation functions, route calculation,WIFI or GPS – score high. Theoretically, you can leave your smartphone at home for your next tour. The only problem is that you won’t be able to make phone calls or send messages.

In addition, even a powerful display for your electric bike doesn’t come close to the performance of your smartphone. In fact, many networked e-bike computers only develop their full potential once you connect them to an app on your mobile phone.

Finally, there are more and more systems for controlling e-bikes that do not have a real “display” but are designed for smartphones. They often consist of a smart mount and an app. Also in this case, Bosch provides some prime examples.

What an ebike display must be able to do depends on you. If you use your smartphone for navigation and fitness data anyway, a computer on which you can read the charge level and switch to another riding mode is sufficient. However, the situation is different if you don’t want to have a mobile phone on your handlebars.

Display type and size:Do you prefer the display to be as small as possible or rather larger? Even here, opinions differ. Once again, if you use your smartphone as an (additional) control centre, you do not need a separate large screen. If you only ride with a bike computer and want to read a lot of information from it, the display should not be too small so that you can keep an overview even at high speeds. Then a colour screen is also worthwhile. Mountain bikers often prefer a small screen for reasons of freedom of movement.

Settings on the bike: One of the basic functions of e-bike displays is the setting of the riding mode. However, this does not have to be everything. In some cases, you can also use the bike computer to control the lighting or manage an anti-theft device.

View: Even a minimalist display shows you how much power your battery still has and when it is time for a charging station. Depending on the device, you can also see the current speed and distance covered, the time and the temperature.

Fitness data: Do you see your e-bike as a piece of sports equipment and cycle tours as a workout? With a bike computer that tracks fitness data (such as the Garmin Edge), you can keep up to date with your performance. If you want to know not only your cadence but also your pulse, you need to connect the display to a corresponding measuring device.

The name Bosch does not only stand for high-quality drives. The company has also produced a wide range of Bosch ebike displays. They range from the simple Purion to the fully networked on-board computer with built in navigation system to solutions for the smartphone.

Bosch Purion: The Bosch Purionis rightly named. It is a minimalist e-bike display that shows charging status, speed, riding mode, range, trip distance and total distance.

Bosch Intuvia:The Intuviadisplay also concentrates on the essentials. What is special about it is the separate control unit. In addition, the Bosch Intuvia Display can be converted to the COBI.Bike mount.

Bosch Kiox and Kiox 300: This small and robust display with activity tracking is well suited for sporty riders. In interaction with the eBike Flow app, the Kiox 300 is constantly being expanded with new functions.

Bosch Nyon: The Bosch Nyon display has a touchscreen, a separate control unit for while riding and a colour display, and can be connected to the Bike Connect app. With Nyon, you benefit from a wide range of functions in combination with your smartphone and can use the display for navigation, among other things.

Bosch LED Remote:Finally, Bosch offers a handy LED control centre that connects e-bikes with the eBike FlowApp. As part of the Bosch Smart System, it becomes the sole control centre.

In addition to these displays, Bosch 2022 offers several smartphone solutions for e-bikes. These include COBI.Bike, SmartphoneHuband Smartphone Grip. The principle behind this: You connect your smartphone to your e-bike via an app and the respective mount. The mobile phone becomes the central display.

Brose currently offers three displays that fit every Brose drive and can be retrofitted. In terms of their functions, they are much more minimalist than the competing products from Bosch:

Brose Display Allround: The all-rounder from Brose has a display with a 1.5 inch colour screen and six large buttons for operation. In addition to the usual basic functions, you can also use it to control the low and high beams.

Display A:Das Display A ist Yamahas Minimalist unter den E-Bike-Displays. Geschwindigkeit, Batteriekapazität, Assistenzmodus sowie Reichweite und Kilometerzähler, das war’s. Die LCD-Anzeige lässt sich gut ablesen und das Gerät ist robust. Eine Lösung für Outdoor-Enthusiasten, die das Wesentliche im Blick behalten wollen.

Display C:Das 2,8 Zoll große Farbdisplay C kommt mit Bluetooth und Fitnesstracking. Über eine Verbindung mit deinem Smartphone und beispielsweise Komoot kannst du die Funktionalität des Displays beispielsweise um Navigationsdaten erweitern.

SHIMANO STEPS E8000:The minimalist and compact Shimano Steps E8000colour display is aimed primarily at sporty e-bike riders and mountain bikers. It is mainly used to change riding modes, to take a look at the current speed and to keep up to date with the battery range.

SHIMANO STEPS E7000: The functions of the E7000 include the view of speed, riding time, total distance, cadence, support mode, time and battery level. More options are available when you connect the display to the Shimano E-Tube app.

Control units: Giant’s handlebar-mounted control units are proudly called RideControl. They have a few robust buttons and LED lighting that indicates the battery level, for example. The key differences between the individual models lie in the number of buttons and how they are attached to the handlebars. The RideControl Dash stands out because it is the only one of its kind with a small display.

Displays:RideDash displays come in two versions, RideDash Plus and RideDash Evo. Their functionality can be extended by connecting the display to the RideControl app. Then it can be used as a navigation device – at least in theory. In practice, this usually fails due to the poor functionality of the app.

In addition to the displays mentioned, there are a number of others from brands such as Fischer, Panasonic or Fazua. However, the above examples already give a good impression of the different designs and functions you can expect from a modern bike computer.

Sometimes you are not satisfied with the display of your own e-bike or a defect makes a change necessary. In such cases, it is a good idea to upgrade to another model.

In addition, not every Bosch display fits every e-bike with a Bosch drive. Depending on the year and type of e-bike system, there are major restrictions.

We therefore recommend that you inform yourself before changing the display and ask again before you have an on-board computer and an e-bike that do not fit together.

In more detail, this means that most modern e-bikes have a Bluetooth interface that allows you to connect your smartphone to the bike. In addition, more and more e-bike manufacturers offer their own apps that you can use to access your bike and, for example, change the support. A traditional display with a large screen is then not necessary anymore.

Thanks to the new app, BikeTrax users will not only be able to protect their e-bike from theft, but also use their smartphone as an e-bike display. All services will then come together in one place – from e-bike control and ride statistics to automatic maintenance and service plan, and much more. The connection of the PowUnity BikeTrax GPS tracker to the CAN bus of the e-bike will also allow managing further control functions of the e-bike via one app.

You can find out more about the potential of your smartphone as an alternative to the traditional ebike display and what needs to happen so that you are able to use this potential in our article “Use phone as bike computer – why your smartphone is the best e-bike display”.

In conclusion, it can be said that the traditional e-bike display still plays an important role on the market. Accordingly, there are many different models from well-known manufacturers. However, the trend is clearly moving towards smart solutions for networking with smartphones.

The fact that these new solutions are sometimes quite expensive for manufacturers as well as end customers, as is the case with Bosch, is more than a downer.
