All About the Bosch Electric Drive System
The Bosch electric bike drive system is ideal for electric cargo bikes. It's maintenance-free and easy to use, puts out tons of torque, and has an impressive quality record.
The Bosch electric bike drive system is the European market leader working with more than 50 leading European bicycle brands. With Bosch’s longtime reputation for quality and service, it’s no wonder they own 25% of market share in Europe. The Bosch-powered Xtracycle Edgerunner will take you to new heights. It’s the ultimate electric cargo bike.
About the drive system
A maintenance-free Bosch electric direct-drive motor puts out tons of torque and gives you 50 to 275 percent more power when you need it most. This means that you’ll be able to bike up hills much faster than an elite racer, even carrying heavy loads. The mid-drive motor is incredibly efficient and powerful, so you’ll use much less energy under the same conditions than with any other type of motor.
Bosch’s heads-up digital readout allows you to select your level of electric assist and always displays your speed, distance traveled, and remaining range. There are four modes of fun—at the push of a button. It’s like a spaceship or something.
- ECO: All-day assistance, sipping from your battery.
- TOUR: Go ahead, get a little rowdy.
- SPORT: It’s officially a race. Or your burden is really heavy.
- TURBO: Flatten hills, fully loaded. This is “beast mode.”
A single Bosch lithium-ion battery typically gives you a range of 20 to 60 miles. The DualBattery is perfect for tour bikers, long-distance commuters, and cargo bikers. The combination of two Bosch batteries delivers up to a massive 1,000 Watt-hours.
Two motor options: How to choose
Our Bosch-powered Edgerunner can be ordered with either of two motors.
The CX motor
The CX is our standard motor, and is appropriate for the vast majority of cargo bike riders, especially if this will be your first e-assist bike. The CX has a top speed of 20 mph, and has more torque and power for hills, etc., than our Speed motor (see below).
The Speed motor
The Speed motor is recommended only for very skilled riders. It has a top speed of 28 mph, and it might be for you if:
- Your bike-riding skill level is high.
- You have experience on an e-assist bike already.
- You have very tight time windows to make on your daily route or otherwise need extra speed.
Honestly, we do not recommend the Speed motor very often. And while it is faster than the CX on relatively flat ground, it has somewhat less torque and power, for hill-climbing with large loads. Be sure the Speed motor is for you, and call us if you have any questions or concerns: 888-537-1401
Why we love Bosch batteries
Efficient & long-lasting
Bosch batteries are an efficient energy provider with staying power—and the most modern e-bike batteries on the market. These lithium-ion PowerPacks demonstrably have maximum energy density with the smallest size and lowest weight available. They combine impressive mileage performance, a long lifetime, and low weight with an ergonomic design and simple handling.
The high-quality lithium-ion batteries are equipped with a Battery Management System, which recognizes potential sources of error and protects the cells from overload. Bosch batteries are designed for lots of trips, miles, and years of service. The intelligent, electronic BMS protects lithium-ion batteries from excessive temperatures, overcharging, and deep discharge. The BMS checks every cell, extending the life of the rechargeable battery. This makes the time from initial use to the need to replace a Bosch battery extremely long.
Simple to Store and Quick to Charge
Batteries are easy to remove and charge at home. The PowerPacks can also be conveniently charged directly on the bike. Modern Bosch lithium-ion batteries do not suffer from memory effect or self-discharge issues. Bosch batteries with lithium-ion cells can be charged quickly irrespective of your charge level at any time. Interruptions of the charging process do not harm the battery. Complete discharge is not required.
A single battery will fully charge on or off your Xtracycle in roughly 3.5 hours—or to 50 percent in roughly 1.5 hours, depending on the charger and PowerPack.
Long periods of non-use
Even after long periods of storage, e.g., over winter, the battery can be used without recharging. This means Bosch rechargeable batteries do not need to be recharged after a long break in use. For longer storage, a charge status of approximately 30 to 60 percent is recommended.
Which battery is for you?
Whether visiting friends, enjoying a country bike ride in the fresh air, or doing some errands with an e-bike, the PowerPack 400 delivers the energy required. The light lithium-ion battery is easy to install or remove or can simply be charged using the charging socket on an e-bike. Its long life, ergonomic design, and ease of handling means the PowerPack 400 provides reliable support that is strong on performance.
The Bosch PowerPack 500 is the same size as and only slightly heavier than the PowerPack 400 but extends the range. The lithium-ion battery requires about two hours to charge to 50 percent, and the PowerPack 500 takes approximately 4.5 hours to charge with the Bosch Standard Charger. In favorable conditions, tours of up to 55 miles are possible.
DualBattery 800 (400 + 400) or 1,000 (500 + 500)
Bosch’s DualBattery is the perfect solution for tour bikers, long-distance commuters, and cargo bikers. The combination of two Bosch batteries delivers up to 1,000 Watt-hours and can integrate nearly all battery combinations from the manufacturer. The system switches intelligently between the two batteries both during charging and discharging.
