Our Schwinn couplers are compatible with most standard bike models, but not all. Specifically, they require a rear axle with at least 2 mm of exposed thread for a secure fit.
If your bike has a larger axle or a thru-axle, it may not be compatible with our trailers. Unfortunately, we don’t make adapters or parts to accommodate larger or non-standard axles. You make have luck at your local bike shop, as they may have aftermarket adapters that can help.
