From your picture and text the current is first 0.10 mA and then drops to 0.03 mA which is the same as 30 microamperes (uA). 30 uA will discharge a fully charged 9Ah battery pack in approx. 35 years so this seems to be a very well designed standby system. The battery management system in most ebikes will draw much more current than this

Shimano has hub gear with built-in torque sensor Shimano's upcoming pedelec parts include a hub with 8 gears internally plus torque sensor. It is likely they use some kind of fieldbus. That requires a MCU adapter board. But Shimano parts have historically been of good quality so such hacker MCU boards are likely to appear soon. Imagine Shimano system with a Magic Pie...

I have the EN 15194:2009 as well as some of the other standards that is related, like EN 14764 - city and trekking bicycle safety standard. EN 15194 requires, among other things, that an EPAC needs to fulfill EN 14764 chapter 4, 5 and 6. The EN 14764 is only valid for regular cuty and trekking bikes, not MTB, trikes, delivery bikes, etc. Does that mean no MTB or trike can be approved as EPAC (EU Pedelec), or should the EN 14764 chapter 4, 5 and 6 simply be ignored for bikes excluded from the EN 14764 standard?

This is acutally allowed by the new European standard for Pedelecs (EPAC) EN 15194:2009 In chapter 4.2.4.3 Start up assistance mode is defined and allowed: EPAC can be equipped with a start up assistance mode up to 6 km/h designed speed

EN 15194 EMC testing The biggest concern in the standard is the risk of interfering EMC causing the EPAC (ebike) to go wild, as said on page five: "Manipulation of the electronic system of EPAC by other source of interference in the scope of the public road traffic could signify considerable risks of safety regulations for the user of EPAC." The immunity test level has been increased from 3 V/m in EMC immunit standards EN 61000-6-1 and EN 61000-6-3 to 30 V/m in the EPAC standard. The reason said: "These [EMC] standards are unsuitable to obtain the urgent and necessary security level. It can also be noted that the requirements for structural strength and brake performance is based on EN 14764:2005 City and trekking bicycles - safety requirements and test methods. From EN 15194, chapter 4.1 General requirements: Electrically power-assisted bicycles (my emphasis) shall comply with clause 4, 5 and 6 of the European Standard EN 14764:2005 in addition to the specific requirements in clause 4.2 in this standard. Please notice that the EN 14764 related requirements referred above only applies to EPAC-bicycles, and not to EPAC- recumbents, tricycles etc. as those are positively excluded from the EN 14764 standard. Chapter 4.2 has a few additional mechanical requirements that is valid for all EPACs, not only bicycles. The most important one being drop-test of removable battery packs and other mechanical requirements on battery, connectors and wiring.
