I thought the new cargo bike was geared at a really low gear, but now I realize that the #Nuvinci N330 hub is broken. It's currently shifted to underdrive. I can use the shifter to physically move the interface all the way around to overdrive, it doesn't appear to change the hub output. The wheel still rotates just around 1.35 rotations for every full rotation of the cranks. #BikeNerdStuff

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.

Oh, well *there's* your problem..

Mmm, yeah. I probably should've replaced this (more than a decade old!) chainring some time ago. Just look at those shark fins.
