I saw this bike made by an independent bike shop for himself.
It’s an electric longtail and can carry a 300kg europallet, plus the toolbox on the front, plus an extra person or material on the bike rack!
Here is the link to the shop website: https://www.cycles-penet.fr/
I understand this is an impressive amount to tow, and to haul, but how tf does it stop? That’s a lot of weight and not a lot of brake.
If I designed it, it would stop the same way a semitrailer stops, using brake lines to the trailer wheels brakes.
Most bike trailers that are designed to handle that load, usually have a built-in brake system as not to rely on the bike’s brakes. This is often called an “overrun” brake or a “surge brake”, and their design is genius.
And many trailers designed to move hundreds of KG will also have an e-assist motor.
