You seem to have missed the part where I talked about accessibility for people who would struggle to even get onboard a conventional bike with a chain. This layout allows the seats to rotate into position with nothing in the way of the riders feet. For someone who has severe mobility issues...

I've actually ridden a bike that used this technology. It is a side by side tandem bike that would have had a very complex drive to combine the output of both riders. The twin (or more) generator units allow each rider to pedal at different cadences and loads. This layout makes the vehicle...

Unfortunately I have not been able to get more boards made. Just tried today to get some made but the various parts shortages are keeping me from ordering. Not much point in making them if I have to source parts for much higher than normal prices and SMD solder them myself.

What BMS's are you looking at using? These bluetooth ones are quite nice and easy to configure. https://www.lithiumbatterypcb.com/product-category/smart-bms/

I'd be interested let me know when you are ready to order.

Where in Canada are you located?

What kind of price are we talking about? I'm reasonably close. Got any other details on these? a data sheet would be nice to see.

Sold the last one. Going to order another batch once JLCPCB has all the parts in stock. Might be a while with the current chip shortages.

They are not removing the evidence of the past they are just no longer publishing or profiting off of it. Things stop being published for much more mundane reasons every day and no one bats an eye. If they had quietly stopped publishing it we likely would not be having this conversation. You...

I don't really see this as hiding from the past. Dr. Seuss made some really racist propaganda cartoons during WW2, they are no longer being printed and the reflection on that time is credited with the drive for inclusion in his later work. Many of his most celebrated works might not exist if...

I consider the source.

If the foundation had not put out a press release would you have even noticed that these books were no longer being published? There was no organised or even disorganized group of people calling for this. The Dr. Zeus foundation took a look at themselves and decided that some of the works were...

Might be a bit out there but if you are needing to haul 500+ lbs up steep hills perhaps something like this is better suited? geminusbikes.com The pedals being disconnected from the drive feels a bit odd at first but after a few minutes you don't really notice.

Since the extra capacity is not going to kill your weight budget why not go for a pack that doesn't get worked quite so hard. Sure the cells can handle 20C but doing that often will greatly reduce the lifespan. Make the 15 kg pack into two parts and it would be easy enough for someone to...
