Trailer/Deer Cart options?

[FEENIX]

I see. But, how would you attach that to a bike without a rear rack?

Mine came with it, but most rear racks are universal and reasonably priced.

What's the weight limit on the rear rack of your bike?

I am unsure, but I have used it plenty of times without issues. The rack does not sustain all the weight of the cargo; it is mainly used for balance. The rack is made of steel and looks rather sturdy. The carabiner will more than likely give in before the rack. Because of the weight of the cargo, I would worry more about the capacity of the bike's battery to haul it and how far.

I was assuming that the op was looking for a trailer made specifically for a bike.

Yes, I am merely offering an alternative. When I first got my e-bike, I did extensive research on aftermarket carts for e-bikes. Back then, they were very pricey. Since I already had game carts, I rigged them for my e-bike. IIRC, it cost me under $40.
