    If you buy a bike with a Bosch motor, who owns the motor?

    I suspect one aspect of this is that the price at which you purchase a new motor is based on return of the “core” to rebuild it, similar to car battery purchase. i think most Bosch owners here would want Bosch USA to have their motor in stock, and just for that reason would not put up a fuss...

    If you buy a bike with a Bosch motor, who owns the motor?

    The key word here is proprietary. I seem to recall being told by someone who would know that this is why Bosch demands return of the inoperative motor. Grain of salt bc I can’t remember who told me …

    If you buy a bike with a Bosch motor, who owns the motor?

    I can cite my experience. I had a performance Line HS motor failure in Washington, DC. under warranty. My dealer is remote but contacted Bosch, who authorized the motor swap. I chose a DC Trek dealer in Georgetown, DC which was the Bosch-certified bike shop closest to my motor failure. To flash...

    Powerpack 500 not charging

    I was under the impression that if you disconnect the BMS from power, it suicides by design.

    Chain Wear

    I have the new LinkGlide system on my RM Load 60. It’s supposed to triple chain life. I’m at about 2400 miles and 0.5 wear.

    Custom SD Bike Speaker Project

    I’ll say that someone riding by playing their tunes on a speaker is not uncommon in cities like nyc or dc. It’s not that big a deal when you also have honking, people shouting in different languages, wheelie boyz and what-not in the mix.

    Tern 2017 Vektron S10 vs 2022 version

    A 9sp Alivio is a far better drivetrain than a 10sp Deore? The OP is considering a new QH P9, not a 2022 Vektron.

    Tern 2017 Vektron S10 vs 2022 version

    I just looked up the QH P9. The Vektron advantages are that it’s a real folder, if you need this feature, has a better drivetrain (10sp Deore vs 9sp Alivio) and the fully adjustable Andros stem. It weighs about 1.5lbs less, so that’s a draw. What I can tell you about the 2017 Vektron S10 is...

    Tern 2017 Vektron S10 vs 2022 version

    Why does the 2017 need a new battery? I own a 2017 Vektron with 5K miles, and everything is working like new. Incidentally, you should be able to get a new PowerPack 500 for about $800 if you can pick it up. The original Vektron came with the PP400, but I upgraded at the time. How hilly? I’ve...

    route across the USA

    Yes, feel free to PM. The C&O will bring you in to the Georgetown neighborhood in DC, and I’ll help you from there. Depending on where your sister is specifically, it might be better to jump off the C&O earlier, but that takes away from the satisfaction of official completion in DC. HMU on GART...

    route across the USA

    Just a heads up to ppl planning a 50-based route. It is not bike-legal from DC to US301. And nobody bikes US50 out to the terminal point of Ocean City, bc much safer/more pleasant alternatives exist. There are only two spots requiring any engagement with US50. 1) crossing the Chesapeake Bay On...

    Gates Belt Tension Tool

    Krikit (Gates) with low of 30lb (two hash marks below an engraved 50). $16 on eBay IIRC. Worked well.

    Bosch

    Limp mode is exactly what you get with 503 (magnet position error). Has happened to me. Reason you get limp mode is bc the default is to assume that we’re tampering to fool the system into thinking we are at a lower speed.

    Camping a felony? Tennessee Law

    Suspect it will be selectively enforced, but I still don’t plan on going to TN at this point.

    Idea rescinded nothing to see.

    I would guess it’s high-volume items that are put up, like Satiator-related. This tells me they will discount for a big enough buy. It‘s not just Grin in CA, there’s all those products in Germany and the UK. An EBR-based group that buys monthly could have some clout, but the challenge is...

    Range Calculation on Urban Arrow Bosch Intuvia Display

    If your range estimate increased at the end of your ride, it’s bc the last couple of miles were flat/downhill. The estimate is based on recent (last couple of miles) cadence and torque. I was once riding in MD’s hilly “western” shore. My eco range was 75 or so. After the Bay Bridge, I was in...
