Also glad to see there are still real makers in the world. Makers do, period.
Another type of person would've asked for 10M of seed funding for "a revolutionary way to commute to work, target market: the whole world" and would've delivered nothing after 2 years of "working really hard on it".

What I am saying you could hack the power to torque factor to be so high you don't really have to exert very much force at all.
You can't. These bikes are DRM'd to the hilt and any attempt at hacking them will cause the bike to brick itself which you can only reset at the dealership. You can do that three times and then it's permanent. The penalties for having such a hack detected on your bike - assuming you would get away with it - is confiscation. I would strongly advise against such tricks. You can see how much work just changing out the b…
This does not match reality at all. E-bikes are some of the most modify-able and hackable devices out there. Most of the parts are interchangeable, and a decent portion of these bikes are assembled piece by piece. I can change the acceleration profile of mine at will, via bluetooth. Amperage limits, battery codes, everything. I have used many devices and parts and kits, and have never even once seen DRM present.

Yeah that argument for forcing pedaling to me seems like a way of gatekeeping to keep something a little more "pure" without any actual reason.
Not really, without the pedals it's no longer a bicycle but a moped. We have e-mopeds already and there are plenty of rules for those.
> I traced it down to the several KA welding pulse that caused the ground fault interruptor to be EMP’d. Running the welder without ground took care of that. That's a solution, I suppose. Not one that I would pursue, but I'm glad the author got the pack welded without any injury.
Ironically, the only time I ever really got zapped was when I was connecting a scope to what I thought was the ground terminal of a very large high voltage power supply. The only slight problem was that it was a positive ground system...
It’s worth saying that it’s not to hard to train up to being able to do 100-200km rides with no electronic assist. At such distance, the weight saving is probably outweighing the battery and you can use the space in the frame can be used for luggage such as extra clothing. At longer distances the ride limiting factor is comfort, not stamina / endurance - here the Ebike adds nothing
I would like to be able to make these trips 1) faster 2) with less effort.
We really need a terminology to differentiate better between pedal-assist only e-bikes ("pedelec") and electric motorbikes. A "bicycle" that can accelerate without the need to pedal at all is an electric motorcycle, no matter if you put pedal on it or not. I see the two as totally different things: I've tried pedal-assist e-bike and they're great. But... Although I have nothing against motorbikes I'm not cool at all…

Scooters are a plague (and this bike is classed as a scooter, unfortunately, so I'm lumped in with the worst), but a bigger danger is mobile phone use by cyclists. That's roughly 1/3rd of all the adults and 2/3rds of the teenagers here.
> but a bigger danger is mobile phone use by cyclists. Or by pedestrians! My brother curses the number of pedestrians in Glasgow that cross the road while looking at their phones... they're by far his biggest hazard.

As long as they'r not causing problems for other cyclists, they're still a big win in terms of transportation: way less carbon usage and occupies less space.

> From what I can tell they use a cargo trailer for gear as well as extra batteries. This is the main reason if you might ever buy multiple ebikes in your household, buy a drivetrain brand that has generic, swappable batteries that can work on all your ebikes. Buying batteries is expensive (~$1,000 for Bosch). For example, some ebikes don't have swappable batteries (either they're integrated or are a no-name brand).…
If you can charge your batteries up to 60% when you store them for a longer time rather than 100%, then charge to 100% just before you need them. That will keep them around that much longer. Better still if you can avoid discharging them below 15% soc.
As for discharging below 15%, Bosch's firmware is pretty smart about this. It keeps a reserve that's used for powering lights for a few hours after the assist cuts off.

Hint: you won't be able to, the key is embedded in an NXP processor that has it's fuses blown (both sides, controller and battery) and any kind of hacking you want to do will have to be at the sensor level and even there I would advise you to use an older version of the firmware because the newer ones are very good at detecting such hacks.
