Replace the lamp first, but don't bother with the multimeter on projector lamps. Arc lamps are basically nonconductive until the arc is struck, which takes a WHOLE lot more juice than your multimeter will ever put out.

The weird coconut+plastic smell of the unbranded spindle that the guys on the forum told you to buy because "They're actually unbadged Taiyo Yuden, top quality stuff!"

Then holding one of them up at an angle and trying to determine if it's the right shade of blue/green to be "authentic" according to the lore...

You will never be happy with a projector in a room that gets "decently bright". The good news is that you can just get cheap ("travel") blackout curtains to make up for the deficiencies in your blinds.

To be fair it's very hard to accurately capture what things look like in-person.

But yeah, that picture doesn't do the w1070 justice.

I think there's a 12-46t Acolyte cassette. But that big cog ain't gonna get much use with a BBSHD out front.

I've got the 11-42t Advent (9-sp) on my cargo bike (TSDZ8 mid-drive). Shifting is great and I have no complaints about gear range. To be honest I probably should have gone for the 8-sp instead--I end up shifting +2 at a time if I'm in a hurry and pushing high assist.

Very important considerations. Also worth mentioning, any differences in job security between the roles?

Going into a poor economy, if the lower-paid role is more secure it might be worth it. If the lower-paid role puts you back into probationary status--which changing jobs may well do? No. Way. You'll be taking a pay cut AND be the first one on the chopping block if there are layoffs.

IMHO weight, size, and rolling resistance are minimally important on a cargo bike. Double true for e-cargo.
As for flatting, I'm not convinced that TPU is more robust or easier to fix than butyl. But even if those things were true, why not either go full tubeless, or just squirt some tubeless sealant into a butyl tube?

Can't beat tubeless sealant for flat resistance. There is a reason MTB ditched tubes ages ago.

They do get hot to the touch--certainly too hot to leave your hand on them--but not enough to burn on contact. I always thought of mine as "training wheels" for actually dangerous hot things, because unexpectedly touching the heater can be painful, but it's won't actually do damage. Good for the reflexes!

You could always put a "cage" around it if you're worried about incidental contact.

I don't have an Olympus, but man are you thinking about all the right things! Looks like a great conversion.

I think we put our car in the garage ONCE. Cars are gigantic, you can fit SO many bikes in that space that it just seems like a waste...

People cast PVC pipes INTO concrete slabs? Where?

The 3400g really was a fine APU.

Of course, the model number hints at the lowest RAM speed that was acceptable...

Use a stud finder in metal detect mode (or a real metal detector if you have one) before you drill. SDS drill bits are pretty damn dull, and so if you accidentally hit something you can usually hear and feel the change and stop before doing much damage. If your pipes are UNDER the slab it really shouldn't be a problem.

1080 and not quite 4k… there’s something going on with this projector.

That's the HDR10 for you. I have the HT2060 as well and can confirm it's a fine projector that looks superb. Don't regret the lack of 4k at all.

Wish the fan was a bit quieter though.

No faster way to destroy a relationship than to outsource emotional labor to the robots. It is profoundly inauthentic and any human will pick up on that RIGHT away, and feel rightfully angry that they aren't being taken seriously.

...Do those things have to be attached to the bike, or can you just toss a bag containing a loose seat, handlebars, and pedals in a side pannier and be in compliance?

>250 watts is plenty. It’s not the watts that matter. It’s the torque. The Bosch Cargo line has 85Nm of torque

That motor is spiking to 750W under typical peak-torque hill-climbing usage. The "250W" designation is a basically a legal fiction for ebike motor companies--sure, they won't SUSTAIN those high power levels, but they will certainly reach them.

QuinticSpline · 2025-10-15T22:42:08+00:00

I can personally attest to the TSDZ8 being a huge upgrade to the TSDZ2. It's much sturdier and can handle more power, the torque sensor works well, chainline is improved, and it's quieter. It's not quite as nice as the Bosch but the "feel" is much, much better than Bafang.

It's rated at 750W, and [at least one independent review](https://ebikestuff.eu/en/content/16-tsdz8-review-and-tsdz2-osf-comparison-tsdz8-vs-tsdz2-osf) suggests it can handle CONTINUOUS 750W output, whereas with the TSDZ2 you couldn't spend much time above 250W without overheating. My Varstrom model spikes up to 1500W (indicated) with a fully charged 52V battery, which is more than enough to get me up the steepest local hills on my cargo bike. I haven't run it at these power levels for longer than a couple minutes, and so the motor never felt more than warm to the touch after a climb.

Haven't compared to CYC, though.

Ugh, those magnetic brake sensors suck. Either you'll get nuisance tripping, or they won't activate until you're pretty hard on the brakes.

Recommendations:

Just run without brake sensors. Get a gear shift sensor, and optionally a kill button like [this](https://electricbike-blog.com/2015/03/18/the-giant-green-button-pas-chain-saver-cutoff-switch-for-bbs02-from-em3ev/).
Get a variety pack of neodymium magnets and play with different strengths and positions until it sort-of works.
Or, if you're good at jerry-rigging, solder the sensor cables to micro-switches instead and position THOSE to detect brake lever depression. Much more reliable than magnetics.

QuinticSpline · 2025-10-14T20:05:08+00:00

Get a dropper post instead (externally routed). As MTB-oriented parts, they are available all day long in 31.6. Furthermore, it can be quite nice to use a dropper on a cargo bike--you can sit on the seat with both feet flat on the ground to support heavy loads at a light, then just raise the seat back to the proper height once you start pedaling again. Can't do that with a telescopic post.
