Baby #CargoBike's first haul (with me, at least).

#BikeTooter #BikeNYC #Cetma

@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 #cetma)

Hauled three bikes across town on the #Hinterher trailer attached to the big #Cetma #CargoBike. Thankful for the #Tonsheng motor since I never would have made it up the hills on my own! (Took this photo after I removed one bike.)

It would definitely fit on the #Cetma #Largo - and probably even not sideways, so I'd have an 8' long joust board sticking out the front.

Or I could keep the box on the #Margo and position the boards perpendicular to the ground. That might also be easier than putting it in the flat bed of the Largo. 🤔

But the easiest thing, in terms of having the bike already out and accessible, is still the #Kombi.

Unanticipated issue with have *3* #CargoBikes - trying to figure out which one would work best for hauling plywood. I'd prefer to go with the #Yuba #Kombi, but the runner boards are only 22" long; I'd either have to stack the wood up 8' tall (top-heavy), and still have 2' hanging off the back, or stack it up 4' tall and have 6' hanging off the back.

It would fit in the #Cetma #Margo, but sidewalks so I'd be 8' wide. And I may need to take the box off, which is always a pain.

I was looking at using marine-grade plywood for the new #Cetma box, but y'know.. given the cost, it just seems not worth it. I'm looking at $200 for equivalent to a 1/2" 4x8 sheet of marine grade birch or similar woods, versus just getting a 4x8 sheet of a different hardwood for $45 and having it only last half as longer.

I'd also happily use a rigid recycled plastic (HDPE) board instead, but that's somehow just as expensive (if not more).

After riding 300 miles on the #Cetma to break in the #Tongsheng motor, I’ve switched back to my #Workcycles FR8 for everyday rides. The difference in comfort is astounding - the FR8 rolls along on a cushion of air. And being fully upright again means my wrists and shoulders are suddenly much, much happier. #BikeTooter #CargoBike #ebike

Bummed that my #Bafang #BBSHD didn't come with a connector to power headlights.. but I've got my #Cetma Margo with a #TSDZ2 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)

Started some repairs on the #Cetma #CargoBike’s wood box. The salty humid air here really destroys laminated plywood. So far I’ve found this Minwax wood filler is surprisingly easy to use. Off to run some errands and then on to sanding.

The rear wheel on the new #Cetma was a massive pain to remove. I tried to put it back on, and it's *tight*. I just measured it; the hub has a spacing of 135mm, and the Cetma's rear stays have 131.5mm of space. So in order to not have to constantly fight with the rear wheel every time I remove it, I just need to find a big piece of wood (or metal, I guess) and do this: https://sheldonbrown.com/frame-spacing.html

Unsure how the prior owners managed to do this. I'm positive that it was originally 135mm and got bent.

In 2012 I bought my #Cetma Margo; a smaller, lighter bike compared to the Largo or a typical bakfiet/longjohn:

Seattle had lots of hills, ebike motors at the time kinda sucked, and I only had one (very light) kid, so that was fine.

By 2018, I had two kids, and oddly enough my first kid had gotten much heavier and bigger in those 6 years. And his kindergarten was on top of a MASSIVE hill in Seattle (Wedgwood Elementary).

Here's what the #Tongsheng #TSDZ2 install ends up looking like on my #Cetma #Margo #CargoBike. 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.

I want to add a mid-drive motor (#Bafang or more likely #Tongsheng TSDZ2) to this #Cetma:

https://social.ridetrans.it/@Andres4NY/109468987375343649

It has an Enviolo/Nuvinci rear hub, and an #EccentricBottomBracket to tension the chain. I don't really want to switch away from the Nuvinci to a derailleur, but the motor will most certainly not permit the eccentric BB to move & will be replaced w/ an adapter.

Any else done this, and have a suggested chain tensioner model that will work w/ this kind of hub?

Last time I replaced the chain on the #Cetma, the eccentric bottom bracket was just.. stuck. I tried a mallet, I tried some lubricants, but I just couldn't move it. So the chain was really tight, and we just rode it like that.

Today the chain slipped off while my wife was riding it. So she switched to the subway, I went out there, replaced the chain (it was time, it was stretched), and.. with a few swift kicks, I was able to move the bottom bracket!
