Options
The Birdy can carry 10 kg of luggage on the front rack and 15 kg on the rear rack (both racks are optional).
Two optional rear racks are available, the SL Carrier and the Expedition Carrier. The former mounts directly to the swingarm, and allows only the use of a rack-top bag. The latter is a folding 16mm tubular rack mounted on pivots on both the main frame and the swingarm, which allows use of small panniers (e.g. Ortlieb Front Roller) when mudguards (fenders) are fitted. The mounting pivots for this rack have only been fitted to frames since 2003. Both racks are available with rollers which allows the Birdy to roll when folded.
Models are offered outside the US with hub dynamo systems. Fenders are available everywhere the bike is distributed.
A hybrid model is offered with an electric motor in the rear hub. The battery pack is carried on the handlebars.
