The Anura is one of the best Delta style trikes in the world. It’s light, stable, and easy to mount and dismount for people who aren’t as limber as they used to be. The SL in the name means it’s equiped with a Schlumpf Drive. The Schlumpf replaces the front gears with a push button internal two speed shifter that eliminates trouble with the chain falling off. It also can be shifted at a red light before you pedal. For more information please visit our website.
