GET YOUR EXCLUSIVE WALDWIESEL.E!

Gravel E-Bike - Waldwiesel

The electrifying adventurer

With our electrifying Waldwiesel.E, trees and mountains fly past you thanks to the precise MAHLE ebikemotion electric drive and precise Shimano GRX 1-11-speed shifting group.

The world's first 3D-printed Urwahn Gravel E-Bike is bursting with power with 40 Nm of torque at the rear wheel and makes many a squirrel look old. The 250 Wh battery is also inconspicuously hidden in the down tube of this work of art made of steel and can optionally be supplied with additional power with a range extender in the form of a drinking bottle. True to the motto: when the odometer is set to infinity again.

Oh yes, and there's also the issue of lighting, because even in nature, the lights get switched off at some point. For this reason, we have given our Waldwiesel optional bright Lightskin LED eyes that won't let you gravel in the dark from now on.

At just 14.8 kg, the Waldwiesel.E is one of the lightest Gravel E-Bikes and was also awarded the prestigious 3DPC Award 2021 for its innovative Softride technology in the rear triangle. It has barely seen the light of day in the big wide world and already it has its first trophy in its luggage!

We are sure that our Waldwiesel will give you sleepless nights. Fancy a wild adventure?

MEASURE YOUR STANDOVER

Take a spirit level and clamp it between your legs. Move the spirit level upwards your crotch as if you would sit on a saddle and balance the level spirit level parallel to the ground. Next, measure the distance from the ground to the top edge of the spirit level. IMPORTANT: please make the measurements with shoes on.
