My current role is rather diverse, partially I am supporting my support colleagues with technical knowledge, also hands-on when bikes are not diagnosed and solved for the end consumer. Could be in house or at the dealer. Most of the time I am focussing on compliance and quality related matters...

I do, but i would not put it on the test setup. Those benches run for 24 hours a day

like all bigger brands we buy competitors products and test them to our own designs. We do, like others, design frames in such a way that the noise is not that audible for the rider. I cannot disclose test methods and results for obvious reasons, I can only say that the DU's are not that far...

well we do tests for products, the actual DB's for the different drive units not that far apart, the tone/herz is further apart and that more "audible" parameter. Also the frame where it is tested in is a big factor in these cases. And yes, we test them at max torque output.

I suspect this battery cable has an intermittent contact. Its the one coming from the battery pack and leads into the DU the cables on these DU are on the topside, so the du should be tilted downwards to access them.

Most rides are done on a Bosch E-Bike, BDU makes as much noise as the Mahle DU, pitch is different. Same for the Yamaha DriveUnits we have around here, comparable db just a different pitch. the Carqo Line BDU's produce more noise in db and in a range which is more noticeable. Flyon TQ sample is...

Sounds like a problem in the wire harness which leads from the Yamaha DriveUnit to the battery. For this DU the connectors are on the toppart of the DU, so this one has to be tilted downwards to get to the cable connectors. Capacity of the battery can be read after pushing the battery button...

Next thursday there is a christian holliday, so we bridge that day into the weekend. Free from next thursday so we will be out of the city and will ride the SL's from the "datcha" into Zeeland. Long term weather info shows some sun, 20+ degrees C and not to chilly nights, so some cycling, beach...

It's on these Alumee fender-racks from Hebie. https://www.hebie.de/schutz/schutzbleche/feste-bleche/alumee/Should hold 8 kg per side. Currently just checking what would fit. I think I could get to max 6 kg per side for a long weekend. Front bags are trail-mulli's from Vaude (yep I know these...

Prepping the bike for some cycle-touring next long weekend. Mix of touring and bikepacking setup. Test run later today.

In theorie Indeed.

wel, i've seen a few cases on spinning axles with TA's...

Non turn washer in frame reaction force arm

we just have Police and Ambulance on service e-bikes our fire fighters just received e-bikes in regions where its faster to cycle to the fire station, so just some plain lease e-bikes for them.... the "wegenwacht" (Anwb, just like the ADAC) just started using e-bikes to service motor...

I would go for a Shimano hub, niet the formula....

the office in Woudenberg was 20 minutes riding ;D current roughly the same just into another direction. Also before moving to Harderwijk the office was even closer in Amersfoort

the RIM of your current wheel is from Rodi, the hub is unknown to me. This Cordo wheel has a low profile aluminum rim with eyelets, a Shimano Deore hub (honestly an good hub) and 32 spokes in a front wheel is usually enough on an E-bike, there are some really wild paths to find around lake Como...

https://www.mantel.com/it/ruota-posteriore-shimano-achterwiel-mt500-29-inch-cl-quick-release that could be a replacement, you would also need to buy a Center Lock rotor https://www.mantel.com/it/freno-a-disco-shimano-deore-rt54 or just something like this...

aha, thats an International Standard or 6-bolt rotor.

Indeed nice bike. those fenders work great, also with panniers. Price is high
