If it comes down to cutting/modding the frame, I guess it is time to start looking at other options. The one thing I've noticed is that the gearing seems unnecessary while using the motor. With pedal assist, starting from a dead stop is quite simple. I'm sure that there necessity will be obvious if I ever find myself without power in the battery, so I'm guessing removing the gearing is a non-starter

I have used a bike with single gears and I currently run my own ebike with a single gear - it's really not that bad if you are in shape. I have pretty strong legs though so ymmv.

Yes, that's exactly the point for me just by myself it wouldn't be an issue.

Interesting information. Agreed that in an unbalanced pack deep discharge is really dangerous, but, and this is where that copper in solution comes back to bite: the bulk of the fires happen during charging, which is when the copper comes out of solution, I'm not quite sure what 'modern' means in this context but all of the batteries that I've seen so far (Samsung, LG, Sony) caution in their MSDS against deep dischar…

I've been using a rear carrier battery too on my bike. It's pretty bad for the center of gravity. I will be building a middle mount for it in the next month. I will caution against it for a heavy pack - it does become a safety issue when the battery is heavy. What happened to me twice is that in suboptimal conditions - rain or dirty roads - it's VERY easy for the front wheel to lock up under braking and for you to lo…

I've seen the aftermath of a battery fire, trust me, you don't want to go there. It's a small price to pay on my end and even if the effect is just psychological that's worth it to me :)

I should do a write-up on battery pack failures, I've collected a small mountain of data on this, it might be useful to others.

Many thanks for the rear carrier information, this is something I will have to really deal with somehow, the frame gap on this bike is just too bloody small and I don't want to permanently alter the bike in case I want to sell it. I've done quite a bit of cycling with kids on the back so I'm used to having a lot of weight there (and one on the front too, total bike weight in excess of 130 Kg), but it's something that will have more effect the faster you go.

What's definitely out is an off-side pack or to have it split across the carrier bags, that's asking for trouble, both from a mechanical point of view and an electrical one (you'd be running quite a few wires between the two sides). At least a carrier one is going to be centered on the bike.

Cells are arriving tomorrow, for now I've decided on a 10x20 grid (so a few more cells ;) ), 21 x 41 cm plus some room in front to house the BMS. the box will be fairly low, about 90 mm altogether so that should help keep the COG low, the carrier is rather low on this bike so on the whole it might not be that bad. I'll be sure to be extra careful with wet roads and I categorically refuse to cycle when it's icy (I have a bunch of steel in one leg from a previous accident so falling again is really not an option).

At least my adapter works, so I won't need to butcher the bike wiring harness.

They still have a gigantic factory in California, they built a battery factory there and have a huge battery research team in California, they have another research team in San Diago and they just announced building a Megapack production factory in California. Jesus why are Califonians so thin skinned.

I'm not Californian.

What is it with the endless whining about this decision, by Californians and you. California got exactly what wanted, its leading in EVs. It got a huge number of jobs, including reopening a big plant. Its leading in battery tech. Those companies help fund their universities.

Tesla is one of the few companies mass manufacturing in California at all. They got more then their monies worth.

Tesla even did really fast charging just not with swapping. So I really don't see why people are so upset about this. Swapping was clearly the wrong solution, and Tesla instead invested in a better solution. Thanks to that California has a huge amount of fast charging stations.

It seems to me what it is really about is just finding any reason to be angry at Tesla. If you actually think about it, with a fixed amount of capital, what should they have done, build battery swap station or deploy fast chargers?

The battery swap stations were a scam to get subsidies. They aren't any more real than the Cybertruck, Model 2, Roadster, solar roofs, semi, or Full Self Driving.

All Model S did support that capability early on. Because of reports about Tesla on fire Tesla added a shield under the car that made hot swapping no longer possible. The reality is, as a company they had X amount of capital to solve long distance driving. It was clear pretty quickly that Superchargers was far better and more scalable technology. When they started with Model S they were not yet sure what the better s…

1. They built precisely zero stations for battery swaps.

2. Tesla has been promising a car for $35k or less for years now and still does not sell one.

3. The solar roofs exist only to give an excuse to bail out Elon's cousins. Installations are currently lower than 20% of Tesla's projections and are declining rapidly. They are bad solar panels because they are more expensive to manufacture, far more expensive to install, less durable, and less efficient than an ordinary installation. They are bad roofs because they are more expensive to manufacture, far more expensive to install, and far less durable than ordinary roofs.

4. The Cybertruck is a concept. They have made not even a single working prototype. There has been no news since the scale model had its glass busted over 700 days ago. Similarly, there has never been a working Roadster and we have seen no real information in over three years.

5. The Semi is an asinine idea and cannot ever work. Trucks have a weight limit and run as close as possible to that limit. Batteries are heavy. Using our best technology an electric semi would have well under half the capacity of a normal one even for very short trips.

> Tesla has been promising a car for $35k

That was their target price before the product launch, must be the first time in history a company didn't hit is project price. For a while they did have a version at that price, that version was supposed to have no Autopilot and few other things were missing. They discontinued that option.

> The solar roofs exist

Oh now they do exist. Don't hurt yourself running down field with those goalposts.

> bail out Elon's cousins

Lol, what nonsense. If it was about that they would have just continued with normal solar panels.

> lower than 20% of Tesla's projections and are declining rapidly

Wrong they are actually increasing, 46% growth in solar YoY this Quarter. And I'm sure that its the first time in the history of capitalism that a company didn't reach the production volume they had planned.

This is a huge growth market and continuing to play in it makes simple sense even if its not a huge part of current revenue.

> They have made not even a single working prototype.

There is literally footage from a prototype on a testing area from like a week ago. And the initial prototype has been driving around all over the place.

> They are bad roofs because they are more expensive to manufacture, far more expensive to install,

They are supposed to be for people who would then put solar on their roof after, of course its more expensive to install. What you should compare it to is building a normal roof and then add solar installation on top of that.

> and far less durable than ordinary roofs.

There are literally videos out-there where in a massive hale-storm you see many people with damaged roofs and the solar roof is perfectly fine.

> There has been no news since

There was 'no news' about a refresh of Model S/X for a long time, they even said its not gone happen. And then it happened. Crazy how companies don't feel the need to update you every second on what they are doing. I guess as soon as company doesn't update you, every project should be considered dead.

There was actually a bunch of news but I guess you decided its a fake product so following it isn't relevant.

And again, they are literally building a gigantic factory, they are LITERALLY ordering tools from suppliers for that factory. IRDA for example has publicly stated they are building an 8000 ton press for the rear under-body of the Cybertruck. There has been some leaked info about Tesla ordering the stainless steal, its actually their own material so they need have somebody make it for them in gigantic quantities.

Literally every indication is that there is a very active program at bringing the vehicle to market, no matter if you like it or not.

> The Semi is an asinine idea and cannot ever work.

Now you are just embracing yourself.

> well under half the capacity

What nonsense.

Fast chargers aren't fast. Watch the swapping demo they did on stage: it was faster than fueling up with gas. But it was all a show and probably never would have been practical with road wear.

I don't love fraud. Tesla loses money on every car it sells and cooks the books by charging for imaginary options. That is cut-and-dry securities fraud.

>Other then building a gigantic factory dedicated for building the car.

Tesla does not operate gigantic factories. They're a pipsqueak.

There are affordable electric cars on the market today with better build quality than what Tesla sells for $80k. Someone will make a killing off affordable electric cars. Every indication is it will not be Tesla.

You honestly sound like a short seller or something. Tesla owns the vast majority of EV sales in US and other countries. You act as if other companies will easily catch up on major moats like battery tech/supercharging network/autopilot, but that Tesla can't improve on Build Quality? Every indication is that it will be Tesla.

You think "Autopilot" is a moat? Every other company has had that stuff for ten years and their systems actually work. Adaptive cruise control ain't new.

And no, I don't think Tesla can improve on build quality. Their cars are fantastically shit. May as well consider Yugo a competitor to Bentley.
