How much weight can it carry?

The frame is rated for up to 120 lbs of cargo. That covers a large grocery run or a full camping kit, but not a passenger or heavy building materials.

The coupler is described as universal and suitable for most bicycles. Check your rear axle type and hitch area before ordering, since very unusual frames may need a different mount.

Does it keep cargo dry?

It comes with a removable cover that protects items inside from damage and weather. The cover is the stated protection, so plan on dry bags for anything sensitive.

Is the frame rust-resistant?

The steel tubes carry an anti-rust powder coating. That helps with rain and road spray, but chips and scratches should be touched up to keep rust from starting.

The trailer, its steel frame and cargo bed, the removable cover, and the universal coupler for attaching it to a bike.

Can it fold for storage?

Nothing in the description says it folds. Expect a fixed steel frame that takes up floor or wall space between trips.

Our take on the thinkstar Harmie Bike Cargo Trailer

The thinkstar Harmie is a single-wheel-style cargo trailer built around a welded steel frame of iron plates and steel tubes, rated to carry up to 120 lbs. The steel is powder-coated against rust, and a universal coupler lets it hook to most bicycles without adapters. A removable cover shields the load from rain and road grit. It suits riders hauling groceries, camping gear or garden loads who want a simple, sturdy box behind the bike rather than a folding or child-carrying trailer.
