Let's make an #e-bike out of garbage. You will need.

* One dumpster bike (free)
* One cargo rack (free)
* One hub motor (dumpster dived, but about $200 new)
* One motor controller (about $20-$50 new)
* A battery (recycled, but about $100 new)

I'm going to rewire some used 12v lithium batteries to make a 36v battery with a smart battery management system (monitor charge from your phone).

I started by installing the front wheel, installing the cargo rack, mocking up where I'll mount the battery, controller and throttle.

Next I'll wire the key components, get the wheel turning, then look at which of the other wires need to be connected. (Some brake cutoffs, pedal sensor, maybe a key lock to see if a wild @alice appears).

This happens to be a folding bike, because that's what was at the front of the bike pile.

@Unixbigot @alice Where do I find these high-yield dumpsters though? 😆

@yngmar we have this thing every two years where you put out large items on the footpath (bikes, old trampolines, furniture, appliances) and the council collects them for free. In practice about half the stuff that is put out gets freecycled by neighbours or professional scroungers (and this is a good thing, IMO).

@Unixbigot Ah, right, we have these too! We somehow missed the last two though.

The council says nobody is allowed to take stuff from the pile, which is luckily widely ignored 😆
