Have you ever wanted to fly like the wind on your wheel... but your legs just won't go fast enough? Do you find a Coker too big and heavy?  The answer is simple, The Schlumpf!

This unicycle is made in Switzerland to a watchmakers precision.  It is the work of engineering art from a dedicated genius, Florian Schlumpf.  The hub is a wonder to behold with is large machined aluminium body and discrete gear change lever in the centre of the cranks.  What is quite amazing is not only is this a mechanical masterpiece but it is also amazingly light and durable.
