Knowledge Base: Tech Details
The Bosch CX Drive motor offers 25% more torque than the regular Performance Line motor - up to 75 Nm at peak output. The CX Drive motor builds upon the basic features of the Performance Line, so if you haven't read this page, you might want to do so first.
In addition to the increase in torque on the CX Drive system, Bosch has redesigned the motor casing to be both lower profile (affording greater clearance beneath the motor when riding), as well as a powdercoated enclosure designed to withstand the rigors of all kinds of cycling, especially off-road riding.
The Bosch CX Drive is made up of three distinct components: the drive unit, the battery, and the console.
The drive unit is made up of a direct drive motor and gear box, the controller, and a number of sensors including a torque sensor, a cadence sensor, and speed sensor. The CX Drive motor is rated at 75Nm of peak torque output (20% more than the standard Performance Line motor. A slimmer motor profile allows for better riding clearance, and hardened case withstands rigors of off-road riding.
The Bosch PowerPack is a 36V battery pack that powers Bosch equipped electric bikes.
New for 2017, Bosch offers two batteries of different capacities for the US market. The Bosch PowerPack 400 is a 400 Watt-hour battery pack, while the PowerPack 500 is a 500 Watt-hour battery pack.
The PowerPack 500 offers 20% more capacity than the 400 Watt-hour pack and adds only 3.5 oz to the overall weight of the battery. While range is difficult to estimate - Bosch has made it easier to predict your useful range with their online range calculator.

All Powerpacks can be charged on or off the bike using one of two Bosch chargers. The standard Bosch charger will fully charge the PowerPack 500 in 4.5 hours and the PowerPack 400 in 3.5 hours. The compact Bosch charger weighs 1.3 lbs and is 40% smaller in size than the standard charger, but takes longer to charge the PowerPacks - 7.5 and 6.5 hours respectively for the PowerPack 500 and 400.
Also new for 2017, Bosch has introduced the Purion, a simple 2-in-1 electric bike controller and console - putting everything you need to monitor and control your bike in one simple package. Scroll through your current speed, assist level, range estimate, and more with the click of a button. A non-glare backlit display makes information easy to view. The Purion, combining controller and console, frees up valuable space on your handlebar for lights and other items.
The Bosch Intuvia console consists of a thumb controller and a larger console mounted at the middle of your handlebar. At the console you can select between four levels of assist and no assist. You can also track your trip computer settings, see how much further, in miles, you have on a charge, and track your speed. The Intuvia console is operable when removed from your bike, and is programable here at the shop via USB.
