EBS News - All Articles

Progress in Lithium Battery Technology As the electric vehicle (EV) and ebike market continues its rapid growth in both the US and the UK, some exciting news has recently been announced which will have a major effect on the industry. Researchers have developed a new battery system which will allow EVs to be recharged almost instantaneously.  This technology, dubbed the ‘Ifbattery’ by its creators, can be produced cheaply and is environmentally friendly. It uses a system known as a flow battery, but has been adapted to work without the membranes usually used in such units. T..

New Display


The most obvious change will be the Bosch display and thumb control.

A new smaller Bosch Purion LCD display with integrated button controls will be positioned within reach of the riders left Thumb.

It replaces the Intuvia thumb control and LCD set used on recent Bosch models and returns in spirit to a format they used on the earliest Bosch models with the HMi display.


This is an unusal step for Bosch because their biggest competitors Yamaha and Shimano supply pedelec crank drive systems with large central displays. It suggests they are courting younger, sportier customers that appreciate a small tidy display, want to use one glance to change settings and see display information and importantly can easily read from a smaller display. Older customers may struggle to see the information although some information such as assist level is larger and clearer than on the Intuvia display. We think Bosch may have the size just right but it will be most interesting to see what our customers think. We will update this once we have customers on bikes and start getting feedback. Before this you are welcome to visit our stores and see and TRY for yourselves.

The usb charging socket disappears - although many customers liked the idea of this feature our feedback shows that few actually use it and so it may not be missed.

Walk Assist - the button no longer needs to be held to keep walk assist on. We are dubious about this change and feel that a bike that can propell itself without continuous rider control has the potential to cause accidents. Further more we do not see any benefit unless many Bosch customers are pushing their ebikes for long distances.


It looks like the button symbols + and - may illuminate making it easier to hit the right button when riding in the dark. This has to be confirmed.

PLUS points for the Bosch Purion Display

LOOK ONCE: So in short a smaller display with big clear characters requiring one glance down to make setting changes and read the information appears to be a good idea. It ensures the rider can concentrate more on the road or track. Hopefully if damage does occur 

BUTTONS: illuminating (probably) to aid quick setting changes and more robust. The Intuvia thumb control although nicely designed and rarely damaged were a bit fragile when knocked. The unit itself is quite tough but the fascia could break and guess what to replace you had to buy a new thumb control! The Purion display should prove more robust.

NEGATIVE points for the Bosch Purion Display

USB: there is no USB charging port. Some may miss the ability to charge their devices.

 

 

Bosch 2017 Software Updates for Nyon 2017


 



The Nyon is a little computer dedicated for ebike use. It offers a huge display and integrates your life with your favourite transport looking after your navigation; fitness and training; wirelessly linking to your mobile phone so you don't have to stop cycling to stay connected. Anyone wanting a larger display can upgrade to the Nyon system. The system comes into it's own for people that are touring or exploring. For 2017 Bosch have focused on making the firmware and software (accessible via a website portal) more relevant and intuitive. Bosch face some rising competition when it comes to technology designed to make our bikes more part of our lives. As more people spend more time on ebikes, getting healthier and happier the market for lifestyle technology is an exciting one for companies like Bosch with the capabilities.

 

Bosch Dual Battery for 2017


This is probably going to be a big hit for Bosch. You will be able to mount 2 batteries on one e-bike up to a total of 1000WattHours. The vast majority of our customers do not need this additional capacity but many will buy it 'to be safe' because of what is commonly known as 'range anxiety'. The double battery option is not suppose to be retro fittable to older systems but I'm sure we will find a way to do this for our customers. The heart of the system is a Y cable connecting the 2 battery hangers. The setup can be used with carrier and frame batteries or 2 frame batteries.



It appears to me that Bosch have again looked carefully at a little known Japanese crank drive manufacturer for inspiration. Sunstar announced their dual battery system the Virtus at Eurobike 2 years ago but despite being an early ebike pioneer have failed to bring it to market yet.



Extra battery capacity if needed can only be a plus point unless someone buys one 'to be safe' and doesn't use it. You can carry just as much battery weight as you need for your journey and you can go even further. It is likely that this option will be very popular with people riding speed pedelecs or dongled Bosch bikes because these use much more energy than standard speed ebikes.

 

Bosch e-Bike Charger for 2017

 

Bosch e-bikes will come with a smaller and lighter 2 amp charger rather than a 4 amp charger.

This will mean longer charge times for the benefit of a 200gram weight reduction and a more portable form factor. One of the questions we are often asked is 'how long does it take to charge?' The answer usually impresses people and a shorter charge time is seen as a technical advantage so Bosch are being bold here.

Live Longer - Charge Slower: Bosch have benefited from lots of user data over the last 6 years and they know that most people charge over night and so the charge time is rarely as important as people think it is - but why change it Bosch? Surely charge time should be as fast as possible so it looks impressive next to the competition! We are happy to see Bosch taking a risk with charge time because there are significant benefits to be had from slower charge times and Bosch are showing a good understanding of their customers and their technology. Lithium batteries like to be treated gently and charging slowly is very likely to lead to longer lasting batteries. Given the cost of qualty lithium batteries customers are likely to value this more than fast charging (assuming it's explained correctly). A smaller charger is more portable so people are likely to bring it with them and perform regular top ups. Again lithium batteries like to be topped up rather than run flat and a shallower depth of discharge leads to significantly increased battery lifetime. A rough quantification of this would be to suggest that a standard lithium battery can perform 800 to 1000  full charge / discharge cycles above 75-80% capacity. The number of half cycles could be as much as 5,000.

Bosch eBike Motor Options for 2017


The motor options will remain the same with Active Line and Performance Line systems. Active is designed for urban use and Performance for sport and touring.

The Bosch system is one of the smoothest and most reliable electric bike systems on the market. I hope you've found the information above useful. If you have any questions please contact your nearest store or email me Community@ElectricBikeSales.co.uk
