I'm relatively new to Bosch so have to see what all I have access to via the app. But it's hilly enough in our area that her having the motor start up more-or-less instantly on crank rotation (whatever the default is) is probably more helpful, especially because this bike is an upright-seated...

Isn't that where everyone puts theirs?!? ;) Ok, ok, another topic for that other thread!

I'm not familiar with Dynamic so I assume the former, and almost for sure she's in Eco for what that's worth. Neither of us can replicate this, but the best guess we've come up with is she's in a higher gear because it's at the bottom of a descent, she is just about stopped and probably...

Bosch Performance Line CX from the 2022 model year on a Bianchi step-thru city bike.

Ah, true, except when it's not. The whole reason this thread forked is I mentioned my wife has suddenly had a few motor "excursions" while rolling to a stop on her new-to-her bike. What I wrote earlier is that it's almost for sure some habit she needs to unlearn, but a kill switch on the brake...

Thank you for that reasoned answer, that seems like a good alternate use -- as does another rider who said he would lightly squeeze the brake lever to cut the motor briefly while completing a shift under load. I found some references to CA vehicle code 406(a) that used to read (paraphrasing)...

What I'm getting at is that my ebikes have been all reputable brands i.e. Shimano / Bosch drive systems, from Raleigh / Felt / Bianchi / Yuba / Electra (Trek). None have had this feature. I would expect that if this was recommended for safety, I'd have come across one in the past 10 years. I'm...

So is this safety switch connected to a brake lever also found on mid-drive bikes that are equipped with throttles? A brake pedal motor cut-off is common, maybe even standard, in electric cars. You can imagine it causes a problem for two-foot drivers. Most EV drivers on the forums don't even...

I know nobody here is waiting with bated breath for an update, but nevertheless I feel like I owe this thread something. Fun Fact: if a Shimano ebike with a rear wheel sensor is towed, even though it's powered off, the computer accumulates miles! Huh. Probably wouldn't have had I pulled the...

Oh? I suppose that is reasonable and even practical. @kevinmccune nope this one is mid drive, and with no such brake lever interface.

I'm not sure how that could be possible as they are independent, unconnected systems.

Hmmm, yeah, very well could be, though this bike has a Nexus 5. Her previous ebike did have a derailleur, but her mountain bike has a Rohloff, her previous pit cruiser / beater bike was a Sram Spectro S7, her city bike has an Alfine, so she's got years and years of experience on gear hubs and...

I'll add this: my wife recently began riding a bike with a Bosch Performance Line CX and a few times now the bike has lurched away from her while she's just about to come to a stop at a traffic light, usually while on a gentle decline but also at least once on a flat street, probably while she's...

BTW @PedalUma what are your thoughts on the strength of the 50T cog? I recall when Shimano first began pushing past 34T, there were complaints from the MTB community that they could literally "fold over" the cog with enough pedal torque. This was probably still in the 9-speed days, and since...

I am a dyed in the wool gear hub guy (actually, recently, modify that to gearBOX guy with a Pinion in the mix). But I wasn't at all familiar with the company 3x3, nor their NINE gear hub, until I ran into a bunch of the roadblocks in the way of getting a 142mm compatible Rohloff. This...

BTW been playing around on the Sheldon Brown gear calculator (yes By George that page is still up and running and updated with the 3x3 Nine hub, OMG) and on it there is a link to Mike Sherman's speed calculator. Unfortunately Mike Sherman's speed calculator doesn't yet have a option for...

Hang on a sec there @PedalUma , you're saying you run a 50T pie plate and an amped-up motor? I'm pretty sure I could rappel up the face of the Kaiser Building with that arrangement. At one time I had considered adding a motor to the existing Xtracycle conversion, a bike I love dearly, but fate...

@Jeremy McCreary I think a better answer to your cadence comments is that I tend to pedal my e bikes like I pedal my analog bikes, fast spin, so I'm evaluating these gearing options with that in mind. If I tended to lug my e bike motors and relax my cadence, I didn't know where I'd be with...

None but one of my bikes have cadence sensors, I'm a high-cadence pedaler but this is largely seat of pants. My knees definitely have a preference for high cadence / low gear to tugging a loaded bike up the hill. Actually, here's something else that helps inform my decision: Yuba's...

That's close to the root of my thinking, @Jeremy McCreary , but I can't really know til I know, ya know? And 99% of the time this low gear consideration will be an academic exercise. Being a heavy gear hub user, this is always my predicament: any consideration for low grading always compromises...
