E Gravel
Meet the new E Gravel

The new Principia E Gravel is ready to hit the country roads and trails. E Gravel combines a hybrid bike's manoeuvrability with the freedom of a powerful E-Bike system. The ultra-low weight of just 14.5kg is visible in the subtle design and is felt through the riding characteristics.

In order to create a non-intrusive control experience, Mahle have designed the iWoc ONE remote to be integrated in the top tube. However, the iWoc switch is not just a regular on/off switch, but an intelligent system to control your E-Bike. The iWoc One allows the rider to toggle between the different support levels, while the colours of the LED ring indicate the support intensity, battery level and if a Bluetooth connection is established.

The MAHLE X35+ rear hub motor offers up to 40 Nm of natural and almost drag-free support. This system makes the E Gravel almost indistinguishable from regular bikes and provides style and utility alike that is unrivalled on the market.
