Electric Cyclery > Bionx Surly Big Dummy Xtracycle Cargo Bike

all terrain electric bike from Hannebrink
Designed in conjunction with Xtracycle - the masters of cargo bikes, Surly's Big Dummy is designed to carry a lot of stuff easily, and that’s just what it does. Haul groceries, work materials, pets and even humans - just about anything else you’d normally carry in a car.

The Big Dummy's got an upper weight limit of 400 pounds (180kg) total rider and cargo weight, which is more than most people can comfortably pedal with, especially when hills are involved.

That's where the bionx electric bikelegendary Bionx system comes in. We install a high torque 350 watt motor in the rear wheel to instantly amplify your pedal strokes, compensate for cargo and level out the hills.

Surly's Big Dummy is quite a nice off-road bike too —with 3x9 Shimano LX drivetrain, Schwalbe Big Apple tires, and front and rear Avid BB disc brakes, to name a few.
The Big Dummy incorporates the proven Xtracycle "Freeradical" design into its frame, so it's fully compatible with the wide range of accessories made for the Freeradical platform.

A Bionx Big Dummy rides a bit different than a normal bike, due in large part to its long wheelbase, but a couple of trips to the store is all it should take to convince you that this bike is not only exceptionally useful, but a fun and practical alternative to the automobile.

styriette electric bike

When the first Styriette (pronounced Steery-et) was released in Vienna, Austria in 1938, it set the benchmark for performance and style in the revolutionary new field of motor powered bicycles. Built by Steyr-Daimler Puch with a state of the art 60cc two-stroke motor, it could propel riders around the Austrian region of Styria at up to 20 mph with style and practicality. Over 70 years later, the Styriette has been re-imagined and re-launched for a new century with a completely new design based on the award-winning and industry-leading Bionx Intelligent Mobilty™ electric bike system.
