Rode the Cetma across town a couple of times this morning with the trailer, a bike, and a bunch of random stuff. Not fun on the hills without the motor!

I'm planning make a rain cover for the new (paying $500 for a rain cover feels weird when I spent $600 for the entire bike). However, I'm hoping to not have to sew or really expend much effort. So far, I've got 6mm tent poles, a double side-by-side stroller rain cover, and some metal snaps. The stroller cover fits nicely even on the 32" wide box. I still need to figure out how to attach the tent poles to the stroller cover.

One of the things I never liked about my other 's blaq designs rain cover (which, admittedly, was high quality and has lasted > 10 years so far) is the included poles don't break down. So when you were riding around and it was sunny, there was no place to stow the rain cover. And because there was no place to stow the cover on/in the bike, there were times when we didn't have the cover and suddenly the weather got bad. Ultimately we just always kept the rain cover on because of that.

"Hm.. 1 quart should be enough to paint the bike box, I think."

[..days later..]

"Alright [], you go ahead and shake this [closed] can while I run in for 15 seconds to fill this container up with water."

(The paint that's visible in the can is all that remains after the rest was dumped on the ground)

I like the color, but I think it'll need another coat. You can see where the kid did the painting. 😂

I finally got around to building the box.

I'm going to cut out a rectangle about 12" long and 4.5" deep from the top of the box on each side to make it easier for kids (and dogs; I remember having to lift a 70lb dog into the old cargo bike box) to get into and out of the box. If this is a bad idea for some reason (maybe a swinging door is better? Maybe this will make it wetter/colder in the box if we get a rain cover in the future?), tell me now.

Close-up of the side of the bike box; it is not yet stained/sealed plywood. A pencil marking shows where the cut-out will be (one on each side of the box); a rectangle along the top of the box with rounded edges. Along the top of the box, a black cat tail is popping out. In the background, a cardboard box with the text "ebike motor" on it.
Top-down view of the inside of the bike box. The bike platform is black, and the orange bike frame is just barely visible. There's a 1x4 extending the bottom of the bike box past the frame, making it wider than the bike itself (the box is 32in wide, while the bike itself is something like 26in wide). A black cat sits in the box, cleaning/biting at its toes.
View from the back of the bike. The rear Enviolo CVT hub is visible, along with a black fenders and black rear tire. The bike frame is orange, and the black mid-drive motor and clear-ish black battery that's mounted behind the box on the platform is visible. The sides of the box extend past the orange platform frame by 3-4in on each side, and also drop below it. A black cat's head sticks out of the box.

Has anyone experience with transporting a newborn by bicycle? I researched a ton and am truly surprised how nontrivial it is. My main question is: at what age did you start transporting them by bike and with what equipment? My kid is just a month old now but I really would rather not want to rely on public transport until she is 6 months.

:BoostOK: Boost for reach!

@der_istvan Yes. My first kid we started transporting around 4 months old, the second when she was around a month old. We used an infant car seat inside of a bakfiet (a )

Bummed that my didn't come with a connector to power headlights.. but I've got my Margo with a that does have headlight connectors, & a dynamo hub on the front wheel. So I can move the dynamo hub wheel onto the BBSHD Cetma Largo, & use that for lighting. The TSDZ2 Cetma Margo can switch to using the ebike motor/battery for powering lights.

But seriously, why would you make an ebike motor w/out light connections? (newer BBSHDs now include connectors, I think)

Here's what the install ends up looking like on my . I haven't cleaned up the zip ties yet because the battery is only temporary (I'm going to get a smaller one that fits better).

Instead of the standard anchor bracket, I screwed a chain tensioner into that anchor bolt hole (https://cycles.eco/collections/tsdz2-accessories-parts/products/chain-guide-for-tsdz2?variant=) because eccentric bottom bracket + chainstay. There's some foam protecting the frame in case the motor moves.

Zoomed in on the underside of the bottom bracket/motor, non-drivetrain side. You can see the small chain tensioner cog bolted into the motor. The Motor hangs down below the bottom bracket, under the white frame. There's some cables bunched up under there, too, and sloppily zip-tied.
Zoomed in on the front of the motor, again non-drivetrain side. The black motor hangs below the frame, and nestled between the white bike frame and black motor is a piece of grey (partially crushed) foam. Another unclipped zip tie is on the frame, holding a (not visibe battery) cable.
Non-drivetrain side, zoomed out, viewing the bottom bracket/motor. The chainring is in the background, the motor hangs below the bottom bracket, and there's another rusty old pedal attached to the brand new crank arm. Sloppy black zip ties hold motor wires to the frame. There's a black eccentric bottom bracket visible that the motor is attached to; the bolts for the eccentric BB are visible over the motor's silver lock ring. The eccentric BB is adjusted so that the bottom bracket is at 6 o-clock, because the motor is expected to be installed in a normal bottom bracket with minimal space between the BB shell and BB.

@kevinschaper I decided to keep the G70 hailong battery shared between the bikes, but installed off to the side like so. There's a key lock on one side and the power button on the other, so if it were centered one or the other would be unreachable.

This Cetma came with a Luna wolfpack battery, which was strapped where the back of the box is. During rides it shakes up and down and bends the plastic platform; this is a lot more stable since it partially rests on the metal frame.

view from the back of the same battery/bike. Here you can see that the back of the battery touches the steer tube, and extends left from there (parallel to the back of the bike box).
The battery is gone now, but the battery mount is visible where it once was.
close-up view of the battery mount, showing how it's screwed down to the black plastic platform.
