Review on Aophire Folding Bike Bag: Travel-Friendly Bicycle Case for 26-29 inch Bikes - Ideal for Air Travel, Transport, Shipping by Tres Carmon

I recommend it, but only if you're willing to add more security features. The bag as designed is not strong enough and durable enough to bet on air travel. But with the right mount and extra cushioning between the wheel and frame parts, it becomes air-portable for 29-inch hardtail mountain bikes. This bag has weight and allows you to decide how and what to protect to stay within the weight limit. Because it's soft and compact, it's easy to store away for later use.
