An e-mountain bike from Porsche was recently presented here (ok, it was built by Rotwild). Jeep, Peugeot (also a bicycle manufacturer for a long time), Maserati or the Fiat subsidiary Abarth took a similarly ambitious approach to the development task.

The e-mountain bike from Audi was even more radical. Creating something new was obviously also the goal of the Ford developers, but that was a few years ago and you can see it in the concept bike. On the other hand, it is foldable, which has hardly interested any mountain bikers, but perhaps one or two Ford riders. The Smart e-bike from 2012 also looks like an outdated vision of the future.

Bikes from luxury brands are a category of their own, and are often offered in the corresponding price range. An appealing non-motorized model is available from Lamborghini, for example. The two-wheeler designed for the road from Bugatti, which was priced at 45,000 euros when it was launched, is uncompromising in its pricing. It is intended as an equipment gadget for the Bugatti Chiron, whose purchase price of around 3 million dollars makes the color-coordinated bike a bargain.

The limited-edition "M Bike" from BMW is quite handsome. You also have to give the Bavarians credit for being at least visually up to date in 2005 with their "Enduro" mountain bike.

Of course, sometimes the effort to give the mountain bike an eye-catching look goes wrong and then looks like the Alfa Romeo Cross, for example. The fact that 4WD pioneer Subaru is trying its hand at all-wheel drive is understandable. It doesn't look very inviting and the bike with the four chains hasn't caught on either.

And finally, the most legendary mountain bike ever built under the label of a car manufacturer comes to mind: The downhill bike Honda RN01 with the mysterious gearbox, which Greg Minaar used to win the DH World Cup in 2005 and Brendan Fairclough rode to some of his early victories as a teenager.
