InnoPet
A complete 2-in-1 dog trailer and stroller sold with the bike bar, walking kit, and rain cover rather than requiring a separate conversion purchase. It carries up to 30 kg in a 68 x 40 x 52 cm cabin, weighs 14 kg, and combines 16-inch pneumatic rear tires with an 8-inch flat-free EFA front wheel. Direct EU availability and strong reviews are reassuring, although InnoPet does not recommend trailers behind powered e-bikes and limits straight-line speed to 16 km/h.

PawHut
A steel-frame budget trailer with a hard rear tailgate that folds into a ramp, a 44 lb limit, a 30.7 x 21.7 x 20.9 inch cabin, 16 inch pneumatic tires, quick-release storage, an adjustable leash, mesh ventilation, reflective details, and a flag. The ramp is useful for older or recovering smaller dogs, but the 28 lb trailer is heavy for its capacity and there is no exact-product review evidence yet.

Booyah Strollers
A 3-in-1 trailer, stroller, and jogger for dogs around 40 lb or less. It includes the front wheel and adjustable handlebar, plus suspension, a handlebar brake that assists slowing and doubles as a parking brake, and pneumatic tires. Its 26 x 18 x 18 inch cabin and positive official review distribution are useful, but a 34 lb trailer weight is high for the published pet size and buyers must measure doors and pet fit carefully.


Retrospec
An affordable folding steel trailer with a 50 lb limit, 30 x 19 x 17-inch interior, rear dog door, internal leash, anti-slip floor, 16-inch air-filled tires, weather-resistant 500D shell, canopy/mesh layers, and rear storage. It delivers strong value and a good official review signal, but it is not recommended for thru-axles and visible owner feedback reinforces the need for slow corners and mesh inspection.

Schwinn
A widely available 50 lb trailer with a folding frame, quick-release 16 inch air-filled wheels, adjustable internal leash, universal coupler, washable nonslip liner, rear dog door, bug screen, and safety flag. It gives the expansion its strongest mainstream review evidence and a moderate purchase price, but it is bike-only, publishes only overall dimensions rather than cabin dimensions, and lacks suspension or a parking brake.

Burley
A 21 lb bike-only trailer with a 75 lb capacity, aluminum frame, 16-inch wheels, mesh windows, low rear tailgate, removable floor, compact fold, storage pocket, and flex connector that lets the bicycle lie down while the trailer stays upright. It is easier to tow and store than conversion models, but stroller mode and an integrated parking brake are absent.
