Bosch sells its 2A charger (~80w) for $93, and it’s still 3x6x8 inches and weighs a pound. If I could use my MacBook Pro 96w brick, I wouldn’t have to haul the Bosch charger to work.

I also have a Serial1, and there were no available chargers for a few years.

There is also fire risk when bodegas try to charge many bikes. If the bikes had the BMS and DC-DC on-board, and just used USB-C to get the electrons, we may see fewer fires.

Minneapolis MN USA allows them on light rail, but the racks on the front of the bus are limited to 55lbs (so a 46 lb Soltera is OK if you can lift it into place)

We have a Tern GSD (both wheels are 20"). I think having the back wheel smaller is important if people are going to sit on top of the rear rack. The smaller front wheel does allow more stuff on the pizza rack. But I also have an old 26" MTB with pizza rack, and it can carry plenty of camping gear up front, even with the 26" wheel.

The down-side of the smaller 20" wheels for me is in snow (not a problem for everyone!). I crashed once, even with studded tires, while I’d ridden that MTB with studded tires all winter for years without falling. Also, there is only one studded 20" tire available, and it is not knobby enough for me.

Having both wheels small definitely make it easier to store. I had an Xtracycle Free Radical attached to the MTB, and that bike was long and hard to park.
