  • Towing Thule Chariot Trailer with Rad e-Bike

  • Thule Thru-Axle Adapter for a Thule Bike Trailer on a Specialized Turbo Vado E-Bike
    I have a solution, but I couldn't find that specific part number in our parts. I did a little bit of research and it looks like Specialized Turbo's usually have a 15mm x 100mm front fork and a 12 x 148mm rear hub opening with a Shimano gear kit. We have the Thru Axle adapter, part # 20110733 available, but you'll likely be better off with part # TH20100766 which is an m12 x 1.5 sized axle.

  • 12mm axle to Use a Chariot ezHitch w/ a Radwagon 4 ebike

    As long as your mountain bike has a solid or quick-release rear axle, then the ezHitch for Thule Chariot Bike Trailer - Axle Mount - Solid and Quick-Release Axles # TH20100796 will work on your bike. If your bike has an Shimano or SRAM internal hub then this won't be compatible and you would need a different part. I've listed those parts below.

  • How to Determine Correct Adapter For ezHitch
    That's a good question, and to determine the correct adapter, or if you can use one, your bike will need to have either 12mm through-axles or internal gear hub. If you take a look below at the linked instruction manual, there is a guide on how to choose the right one. You will need to know different things for a 12mm through axle or internal gear hub. For example, an M12 x 1.0 mm thread pitch through hub with a 160 mm length would need the Syntace Hub Thru-Axle Adapter for Thule Bike Trailers...

  • Compatibility of Thule Bike Trailers with a 29 inch Bike Wheel
    Thule Bike Trailers are actually designed for a wide variety of bike sizes and shapes. The only limitation is when they have specific rear axle types and gearing, which is solved with an adapter. The trailer itself attaches via a quick-mount arm that attaches to a mount on the bike's axle, and swings wide of the wheels. My favorite design of these trailers is the Thule Chariot Cheetah 2 seater, part # TH10100824 (Or 1 seater, part # TH10100426) because of the ability of the front stroller...
