Cycling infrastructure (Separated bike lanes)

Northern Light said:
The Infrastructure and Environment ctte is meeting this morning, and currently discussion the Cycling item.

I had a look-see through the myriad communications.......

3 Residents Associations (Rosedale, Summerhill and Vale of Avoca) and the Rosedale BIA are all opposing the Yonge St. Bikelane.

But more R.A.s are in favour, including the ABC association, Bloor East, Lytton Park and Brentwood Towers.

More peripheral to the area, but Leaside' s Association also wrote in favour, as did Harbord Village

Most interesting support comes from the "City Builder Coalition"

The Ctte will be hardpressed to get through this item today, there are 89 speakers on the list for this item!
 
They got through it a few minutes ago.

The item sailed through.

Only amendment was a friendly report request for a report/study by transportation for how to improve safety on the nearby side streets with a particular eye to changes that might discourage cars from illegally driving on sidewalks.

That was from Cllr Saxe and also passed easily.

My only area of complaint (as a driver, I am also a biker but for this complaint I am stating as a driver) is that for the Mount Pleasant Cemetery area, there is a large portion that limits cars to one lane in one direction unnecessarily. While I understand for a pilot you don't want to be tearing up medians, if they do this permeneantly, the bike lanes could easily be pushed onto the median.

That way, the car barrier on the left could actually be used to protect the bikers as well. And there could be 4 lanes here still.

The City is looking at removing an additional lane here and I would tend to support that.

Here's the reasoning. Just to the south and just to the north, there is no room for the extra car lanes.

So if you create a temporary widening to 4 lanes, the result is then than the traffic must merge at both ends of that widening back into one lane each way. The merges back-up traffic more than if there was a single flowing lane.

****

Keep in mind the City intends to narrow Yonge all the way up and remove one lane each way all the way to Steeles, with that reduction being 4 lanes to 2 south of York Mills and 6 lanes to 4 lanes north thereof.

4 lane roads usually don't offer much of a capacity benefit over 2+1 configurations.

The only issue however I find is that going south, there is a huge pinch point with people turning left onto Balliol street. Currently cars going south will pass the left turning cars by driving into the bike lane. That isn't safe for bikes, and when they put up some kind of physical barrier preventing cars doing this, the cars will backup into Davisville intersection, which also isn't safe.

They need to find a way to allow cars to pass cars turning left onto Balliol or there will be serious issues.

Looking at the road layout today, and understanding that the second northbound lane at Balliol will be removed, there is room for left-hand turn lane for SB to EB at that intersection.

Looking at the way the road will likely be set up in the future, I don't believe there will be a conflict w/the Yonge to Chaplin Left turn lane, and there should be room for at least 4 cars to queue for left on Balliol.

If the City wanted to retain a right-turn lane at Davisville, however, any new left at Balliol would only hold 2-3 cars max.

There is some room to be had by eliminating some on-street parking here as well.
 

On the horizon (near and far): improved e-bike batteries​

From link. Published July 15, 2022

Super lightweight. Ten-minute charge time. Double the range. Less likely to burn down your store. If I could promise you all that in an e-bike battery, how quickly would you be putting in an order?

Recent developments in battery compositions and management systems promise huge improvements over the current industry standard, lithium-ion. And while some of the developments will take years to reach the e-bike market, some are nearly here. We reached out to researchers, e-bike brand owners, and battery experts to learn what's coming.


Key metrics

To get a sense of the key metrics for e-bike batteries, BRAIN spoke with Ravi Kempaiah, co-founder of Zen Ebikes and a postdoc at Dahn Lab at Nova Scotia's Dalhousie University. Kempaiah, in collaboration with Dahn Lab and Tesla, recently debuted findings on a new battery composition that has a better energy density and charge time than lithium-ion, all while approaching a theoretical longevity of 100 years. Kempaiah hopes to bring this new battery technology to market on Zen Ebikes next year.

"All you need is one fire to destroy your reputation, so safety is number one," Kempaiah said. He said stringent standards like UL certification will increase safety and the perception of safety, and thus, consumer confidence.

Kempaiah also zeroed in on longevity, which is key to sustainability. "This year, 2022, 40 million e-bikes will be sold. At our current rate of battery life, 2-3 years on average, by 2024, 2025, the world has to deal with 120 million kilograms of hazardous battery waste ... If all of that isn't recycled well or if it has to go through complex recycling, then the whole idea of sustainability goes out the window."

Kempaiah's third key metric is energy density. Unless new technologies are able to fit more energy into an equivalent amount of space, the batteries of tomorrow will be forced to weigh more, or deliver less range.

Finally, price is always key. Kempaiah said he's targeted an ideal of $500/Kwh for the end user. A Bosch battery system is currently around $1,550/Kwh.


Alternate chemistries

While Zen Ebikes pursues new materials, Kempaiah stressed that the transformation of e-bike batteries needs to be system-wide. Even the best battery chemistries depend on safe and effective management systems.

For other companies, like ZapBatt and their founder, Charlie Welch, advances made in battery management systems have opened the door for older battery compositions to be put to better use.

ZapBatt is aiming to bring its first product, a lithium-titanate battery pack, to market in the first quarter of 2023. The e-bike industry hasn't seen an LTO battery since the Schwinn Tailwind, back in 2008, but Welch said that the potential of LTO can be unlocked through new management systems. Their proprietary system will allow their battery to be retrofitted to a variety of motors with different voltages.

LTO battery cells promise lightning-fast charge times and longevity (up to 15,000 charge cycles according to the International Electrotechnical Commission), but energy density and cost are still factors. ZapBatt's initial offering will be a 360 Wh battery, weighing in at 9.5 pounds.

By those spec's, ZapBatt's battery has lower capacity and heavier weight than current lithium-ion offerings. And, the company estimates the packs will cost around $1,200-$1,600 per 500Whs. However, there are other metrics. Welch said ZapBatt batteries will offer greater value over time because of their longevity and efficiency.


Looking farther afield

When I asked Bosch USA's quality and compliance manager, Kunal Kapoor, what battery advance he was most excited to see in 5-10 years, he didn't miss a beat: "Solid state batteries are definitely looking interesting. They are safer, they are more powerful." A highly-prized peak of battery technology, solid-state batteries replace the highly volatile and flammable liquid electrolytes that allow the electrical current to flow between the positively and negatively charged parts of the battery with a solid electrolyte. This advance promises higher energy density, faster charge times, and much greater longevity, all while increasing safety. "If we use 50 cells in our battery pack today, if we go to solid state batteries, we may only have seven or 10 cells. That means smaller batteries with bigger range," said Kapoor.

The dawn of this new battery technology is surely rising, as tech giants like Samsung throw their money and energy behind it. They recently announced a breakthrough in their battery efforts, submitting a paper to Nature Energy demonstrating an all-solid-state battery that achieved a 50% reduction in weight compared to lithium-ion batteries, with an energy density of 900 Whs/L. This level of sophistication would smash any current metrics in the e-bike industry, and enable widespread proliferation of cheap, durable, and high-performance battery systems.

While Kempaiah is also excited about solid-state technology, he has a more tempered view of its prospects: "By the time that you hit the price point of current e-bike batteries (using solid state technology), you're looking at at least 2028." Although scientific advancements are undoubtedly critical to developing battery technology, there's a long distance to cover between the lab and the road.


A moment of gratitude

The batteries of the future are becoming less elusive, but in the meantime, it's worth celebrating what we currently have. "I don't think it's very far from ideal already," Kapoor quipped. "Bosch has the 625 Watt hour and the 700 Watt hour batteries. For a daily commute? I mean, we feel it's sufficient. And if somebody does have some more range needs, they can always carry an extra battery pack ... But we think that the technology is pretty mature and it's being used wisely and productively today."
There are definitely sustainability concerns around our current batteries, but the e-bike industry has quickly rallied to the cause, as major bike brands commit to recycling programs like Call2Recycle. Extending longevity is a great value-add for any battery system, but we can effectively manage our e-waste if we plan for it. While of course there are battery failures before this time, Kapoor noted that "You know, (longevity) is very subjective. How long does one expect a battery to last? ... Bosch generation one battery packs, which were introduced a little over 10 years ago now are still being used by consumers. So 10 years, in my view, is already a very long time for a battery pack to sustain."

The good news is that the battery developments of tomorrow only stand to bolster an already-efficient system. We can look forward to significant advances in the industry within the next year, but e-bikes are already creating a sustainable, efficient, and safe transportation alternative. "Interesting fact: 130 e-bike battery packs are equal to one EV (electric vehicle) battery pack," said Kapoor. When we honestly evaluate the state of the e-bike battery, it's clear that we're already living in a futuristic moment for our industry.

However, the motion for that amendment lost.

Subject to Council ratifying the meeting tonight, the Yonge Street bike lanes are now permanent.

Some amendments did pass:

Losing motions were those to hold onto the 'temporary' designation through November; and, of course, the requisite Councillor Holyday motion to spike the lane entirely. Which did get two votes, his own and......
Councillor Robinson.

The final vote, item as amended, passed with only 4 dissents:
