King of the hill - Bosch Performance Line CX drive engine is the strongest of all of the current big three motors - whereas almost every other drive has a nominal (aka continuous) wattage rating of 250, the CX is rated at 350 watts and 75 Nm of torque. Although nominal motor wattage is primarily to comply with EU regulations (and off road there are less restrictions). Show
Bosch's most powerful motor is tuned for climbing off road fast, and it is the fastest climber in real world testing, and is also popular for sporty street riding in hilly areas. The Performance Line CX drive unit is Bosch's flagship motor, has what Bosch calls Uphill Flow - support already starts at very low pedal frequencies – this makes it easier to set off uphill or to drive out of tight curves. Turbo Mode, the engine support goes up to 300% - even at high speeds. It is also a great motor choice for heavy cargo bikes facing steep hills, or really for anyone who wants no compromise climbing and a bike limited to 20mph assistance. A street setup popular on Riese & Muller is to run the CX motor with either Rolhoff or Nuvinci internal gears using a clean & quiet Carbon Belt drive. Shifting under load on an eBike can be a challenge, especially going up steep climbs where even a second off the power and it is back down to the bottom to start again. On human power alone, a rider intuitively backs off the pedal torque ever so slightly for micro-seconds, and that allows for a smooth shift. On eBikes the motor doesn't know you want to shift and what can happen is that even if you have switched gears, the derailleur in back is not able to move the chain up to the next sprocket because it is under tension from the motor. Being the wrong gear can mean losing precious human and motor power on a steep ascent, so timing your shifts just right is critical for a good off road experience. All of the motor systems address this in their own way, but Bosch's shift sensing technology gives them an important edge on climbs because they measure whether the shift cable actually moves. Brose and Shimano "infer" that a shift change is coming by sensing the amount of torque a rider is putting out to lessen assistance for that micro-second to allow a shift, just like it works on an unassisted bike. Both work - but riders seem to be split on preferences for each style. You should test ride both and decide which you like better. Battery configurations are currently 400 watt hour, 500 watt hour, and dual 500 or 1000 watt hour, and either rack mounted or downtube. For mid 2018 powertube will be a integrated battery option.  If you are replacing the bearings yourself, you can identify which bearing goes where and individually purchase just the ones you need! These are all the common bearings in the Bosch ebike Generation 3 Active Line, Active Line Plus and Performance Line motors. Bosch Generation 3 (BDU3xx) motor (NOTE: Large chainring) September 11, 2019 To coincide with their 10-year anniversary, and after much speculation Bosch recently introduced their new 2020 motors – that’s right, plural. And the innovations continue with the SmartphoneHUB display and new powertube batteries. Bosch eBike Systems – three exciting new motors in 2020While the press has focused on the highly anticipated Gen 4 Bosch Performance CX motor there are also two more exciting motors – the Bosch Cargo Line and an updated Bosch Performance Line.
Key features for all new motors – building on the Active Line Plus
When Bosch released the Active Line Plus it created speculation that this was the new platform for a revamp of its other motors and…that speculation is correct. The new Performance Line motor is built on the same Active Line Plus platform and that platform has provided the basis for a completely redesigned and new Bosch CX platform. The new motors all have the following features:
Additional Features per MotorThe New Performance Line CX motor ("Gen 4") – a complete redesign of the flagship motorThe new Gen 4 Performance Line CX motor is a complete redesign on the original Bosch CX motor (now referred to as "Gen 2"). It is a brand-new motor. In addition to the overall changes mentioned above, highlights of the new motor are:
The New Bosch Performance Line ("Gen 3") – for sporty riders and commutersBosch consider the new 2020 Performance Line model to be the most versatile drive system in the portfolio. It is designed with recreational athletes, trekking and touring riders in mind, as well as commuters. In addition to the overall changes mentioned above, highlights of the new motor are:
With a maximum torque of 65 Nm and up to 300% support, the same level as the “Gen 2” Bosch CX motor, the drive unit offers a natural sporty ride and accelerates dynamically and powerfully, even at low cadences. This is one of the quietest drives in its class and also very strong and smooth making it ideally suited for the demands of trekking, longer distance commuting or eMTB use. Bosch Cargo Line – a completely new motor concept for transporting heavy loadsThe Cargo Line motor is especially developed for cargo bikes – specifically for heavy loads of up to 250kg. It is based on the same platform as the Gen 4 CX motor however the software has been mapped to provide up to 400% support. Even at low cadences it delivers full power, something especially noticeable when starting off at traffic lights or on steep climbs. From a software perspective the Cargo Line motor is interchangeable with the Gen 4 Performance CX motor so the software can be re-mapped to the other setting depending on your preference. Summary: Bosch eBike drive systems available in 2020New technology means progression and new designs. Always a good thing. It also means that manufacturers will be redesigning frames to accommodate the new motors and bikes and getting their production lines ready to build them. This takes time so not all bikes next year will come with the new motors. Therefore we will have a significant variety of drive systems to choose from. At the time of writing brands such as Riese & Muller, Focus, and Kalkhoff have released their 2020 range of ebikes with a number of models featuring the new technology and a number of models retaining the current drive systems. Here is a snapshot of the different drive systems that will be available: Other Bosch eBike Innovations for 2020Displays: Introducing the Bosch Smartphonehub DisplayBosch continues the trend in ebikes towards making things more connected with the introduction of the new SmartphoneHub display. The display is centrally located on the cockpit and makes use of the COBI.Bike app on your smartphone to function as an intelligent control centre. Download the app to your smartphone and you are good to go. The functions range from fitness tracking to navigation to calls. It connects to other services and apps such as Strava and you can also navigate with voice guidance (fantastic for touring!). It charges your phone while you are riding too. There is also the option to ride without your smartphone, with a small ‘back’ display showing the critical riding data (ie. what we get using the Purion display). Summary: Bosch eBike displays available in Australia in 2020In Australia we could see manufacturers utilising four different displays on their 2020 ebikes: The tried and tested Intuvia and Purion displays; OR, the colourful Kiox display or the new SmartphoneHub display. These are most likely to be upgrade options or will come as standard on premium models. Batteries: Introducing the 625Wh powertube battery (and more)Bosch have also extended their range of internal 'powertube' batteries. Of particular note is the new powerhouse, the PowerTube 625. This has a whopping 625Wh capacity, designed with long distances in mind. The extra power comes at a price though. It is a big battery and is a few centimetres longer and 700 g heavier than the PowerTube 500 which means that frames will need to be manufactured especially to accommodate its size. So, if you are hoping to upgrade your current PowerTube 500 to a PowerTube 625 this won’t be possible unfortunately. For those who are finding that 500Wh is not quite enough though, the powertube 625Wh is a great option. We expect that tourers and long-distance commuters will be quite keen on it, especially with the 6A fast charger that is available now. Bosch are also releasing a PowerTube 400 which has the same shape as the PowerTube 500. With a capacity of 400 Wh, the PowerTube 400 is suitable both for city bikes and as a spare battery to carry along on long eMTB rides. Conclusion: Lots of choice = happy riding.
2020 is promising big changes in the eBike world. We will see a raft of exciting new ebikes hitting our shores utilising the new motors and innovations. On the flipside manufacturers will be looking to balance the uptake of the new technology with the changes required through their production lines so it promises to be a year where there will be significant variety available. This is great from a consumer’s perspective. Whatever your choice, current system or new system, we know from experience the end result is happy riding.
