Best cheap e-bike trailer hitches

Start with the Booyah 15 mm angled hitch — it's the cheapest thing here built specifically for electric bikes, and it's the best-rated of the budget options, so you're not gambling on an unknown clone. Angled design clears most e-bike rear racks and fenders.

Who the others suit:

• QuietKAT two-wheel hitch replacement — solid axles up to 10 mm or 9 mm quick-release; the pick if you already run a QuietKat-style trailer.
• SWETRACE 2-pack — you get a spare coupler for a second bike or trailer.
• DRAFIDEEP heavy-duty adapter — quick-connect for repeated on/off, plastic-and-metal build.
• EUNORAU M12 hub-motor adapter — only if your e-bike has a rear hub motor with an M12 axle nut.
• Robert Axle Project Kid Trailer adapter — the safe choice for kid trailers on Rad Power/Bikemotion/Mahle motors.

Check your axle type before buying: thru-axle bikes need a thru-axle adapter, not a bolt-on coupler.
