BOSCH:

Drive Unit Performance

 

The Performance Line is designed for athletic and powerful riding and does justice to its name. Its dynamic drive impresses with high-performance support on any terrain: from flat to steep, from asphalt to trail. The Drive Unit invariably masters every style of riding.

 The difference is the technology behind the design of the components. The drive system convinces with powerful electronics and a low-vibration motor as well as low volume and weight. The optimized 3-sensor concept measures 1000 times per second with maximum precision for optimal power tuning and a new, unique riding experience. The optimal balance of performance and range is also a matter of pure enjoyment.

 

PowerPack 300 & 400

 

Reliable, durable energy storage without memory effect and self-discharge – that defines the rechargeable batteries PowerPack 300 and PowerPack 400 The Battery Management System (abbreviated to BMS) protects the batteries against overload, undervoltage, and overheating. High-quality Single-Cell Monitoring (SCM) measures the voltage of each individual cell.

 PowerPack 300 and PowerPack 400 are lithium-ion batteries with 300 Wh and 400 Wh, respectively. They are available in each case as rack or frame batteries. The latter sits very close to the center of gravity, which has advantages in maneuverability. The battery is mounted on the rack on bikes with low entry. No matter where they are attached – removal and charging of the batteries at the next outlet is simple.

 Lightweight:

Lowest weight in its class

Charging time:

Fastest charging of all eBike batteries

Usability:

Simple handling thanks to handle and mount

Service life:

Battery Management System and individual cell monitoring for a long battery life

 Ergonomic design – perfect handling:

Thanks to the handle and mount, the batteries can be easily inserted and removed again. The only thing easier is charging the PowerPacks directly on the pedelec.

Easy to store and charge – anytime and anywhere:

Lithium-ion batteries have neither memory nor self-discharge effects. This means the PowerPacks can also be partially recharged at any time – without affecting the service life.

In anthracite-colored and platinum-colored design in accordance with the Performance and Active Line, the on-board computer Intuvia Active presents itself as the control center of the eBike. It features simple, intuitive, and safe operation on the separate control unit.

Switching between the five riding modes plus walk assistance and calling up information such as speed, charging state, distance, and much more could not be easier. Even when removed from the eBike, Intuvia remains a useful information tool that makes it possible for you to retrieve all your tour data. The new shift recommendation shows an arrow to indicate the optimum moment for shifting gears. In this way you conserve both your own energy as well as battery power.

A USB port also allows you to charge external hardware such as smartphones and MP3 players. With Intuvia Active, high-precision distance measurements are now possible even after a wheel change. The eBiker himself can make fine adjustments to the wheel circumference at the touch of a button.

The five available riding modes – Turbo, Sport, Tour, Eco, and Off – can be easily and conveniently selected via the separate control unit without it being necessary to take one’s hands off the handlebar. Bosch offers the right riding mode for every riding style and every eBiker.

Riding modes

The Bosch eBike System provides five different riding modes to choose from. The right one for every eBike rider and every riding style.

 
Riding mode  
Turbo Direct, powerful support up to maximum cadence for ambitious and athletic riding
Sport Immediate, powerful support for athletic riding off road and in city traffic
Tour Steady support for long tours
Eco Effective support at maximum efficiency for maximum range
Off No support, all cycle computer functions are available
 

How fast do I ride? How far can I still go? And wasn’t this hill steeper before – or is that due to the selected support recommendation? With a glance at the operating computer Intuvia on the handlebar, these questions can be answered for the eBiker faster than they come up. The five available riding modes – Turbo, Sport, Tour, Eco, and Off – can be easily and conveniently selected via the separate control unit depending on trip distance and the rider’s wishes, and even without it being necessary to take one’s hands off the handlebar.

The new shift recommendation shows an arrow to indicate the optimum moment for shifting gears. In this way you conserve both your own energy as well as battery power. The integrated walk assistance can also be controlled using Intuvia. When it’s time for a break, you simply remove the operating computer to read the tour data at your leisure. And because Intuvia even has a USB port, you can use the modern eBike operating computer to charge your mobile phone or MP3 player even while you are on the go.
