This topic has always fascinated me, and I’ve actually thought about doing something like this for years. Just not with dogs 😂
I’ve been cycling for over 54 years. When I was about 8 years old, I had someone build me a custom trailer for my bike. Later, when I had kids, I upgraded to a bike trailer designed for carrying children.
One thing I learned early on is that pulling a trailer feels like hauling an anchor up Mount Everest. Compared to using a rack and panniers, the wind resistance of even an empty trailer is significant and exhausting.
Around 20 years ago, after developing a lung condition, I purchased an electric bike. Surprisingly, I found it wasn’t as easy to ride as I’d expected. The added weight of the bike made pedalling harder. As a result, I had to rely more on the electric motor, which drained the battery faster than I anticipated.
The idea of using an electric bike with a trailer sounds great in theory, but in practice, I’m not convinced it’s the most efficient option. It could be useful in some situations, but if I were to try it, I’d likely choose a trike instead. A trike would offer extra stability and greater carrying capacity for batteries, keeping the weight distributed low and on the bike rather than in a trailer.
That said, I still believe a regular bike with a small aerodynamic trailer—or even better, a setup with a rack and panniers—is far more efficient.
This conclusion comes from years of trial and error during my cycling adventures.
