The hub contains the electric motor (brushless, power 250 W, voltage 24V nominal), the battery pack (Li-ion, 8 elements in series, 160Wh), and the ECU (comprising two microcontrollers, a tri-axial accelerometer for slope estimation, a CAN-Bus line, a Bluetooth module). The pedaling speed sensor is integrated into the freewheel mechanism. The HMI is realized via a smartphone App, allowing the cyclist to easily monitor energy flows, instant power from himself and from the motor and set some basic parameters of the system.<\/p><\/blockquote>\n<p>There are so many other recent bicycle inventions like the <a href=\"http:\/\/www.gernweit.de\/wasserstoff-rad\/\">Gernweit H2 bike<\/a> oder the <a href=\"http:\/\/de.engadget.com\/2013\/05\/06\/loopwheels-englander-wollen-das-rad-neu-erfunden-haben\/\">loopwheel<\/a> while I think, the most promising invention will cure some human deficiency: metabolic efficiency is definitely higher at constant speed than during an acceleration and it remains to be tested how this is working in daily commuting.<\/p>\n\n<p>&nbsp;<\/p>\n<div class=\"bottom-note\">\n  <span class=\"mod1\">CC-BY-NC Science Surf , accessed 17.04.2026<\/span>\n <\/div>","protected":false},"excerpt":{"rendered":"<p>There are so many other inventions in disciplines that I know from hear-say only.
