[QUOTE=cubewheels;22366817]Ofc, a trailer.
For what it's worth, I did it last November before I bought a new wheelset. The weight of the battery and me on the bike bent the freewheel axle even more when I hit just a tiny pothole. It forced me to buy a new wheelset a lot sooner than I should.
The battery also spilled a few drops of its contents from all the shaking, might be just water, hope it's not corrosive. I went only 200 meters before I decided to remove it.
I can also sit on the rack but not a good idea. It made the bike quite unstable and front wheel did shimmy.
That should power a nice bright motorcycle headlight with power to spare.
