Seat post sizes that fit the Weehoo® bushings include:

  • 25.4mm seatpost

  • 26.8mm seatpost

  • 27.2mm seatpost

  • 28.6mm seatpost

  • 30.9mm seatpost

  • 31.6mm seatpost

For other seat post sizes such as 29.2mm, there are two methods of fitting the Weehoo® bike trailer to your bicycle:

  • Install packaging tape on. your seat post, where the bushing will rest, to thicken the seat post for the bushing.

  • Buy an inexpensive seat post, slightly smaller diameter than your current seat post, then purchase in inexpensive aluminum shim to make the seat post fit your bicycle frame correctly.
