I rode the tour on 26.05.2022. Really beautiful scenery. With very few exceptions, the technical passages are easy to master on an enduro bike with sufficient suspension travel. I would recommend a trailbell, especially for the first part of the route up from Magglingen. That way the hikers can hear from afar that someone is coming and don't get scared (so there are no nonsensical discussions). I found the constant ups and downs after the central square a bit tedious. The exposed sections and hairpin bends described are certainly a challenge for inexperienced bikers, so it's better to descend too much than risk too much. The last ascent through the forest to Evilard is only steep for the first few meters, then it goes up relatively comfortably. I then turned right and rode about 3 km on the road to Magglingen to do the Bieltrail for dessert. In the end it was 50km and 1500hm (Garmin)

I rode the tour today 26.5.2022 (on Ascension Day). From Magglingen the first kilometers a lot of hikers - but with a friendly greeting and thanks there were no conflicts. But became more and more pleasant...
The ascent from Nods is asphalted and therefore quite comfortable. Before the transmission tower and over the ridge very great views.
The first few meters after the tower were technically challenging..., then it became quite smooth. But constant concentration is required (as well as sufficient air pressure because of the sharp stones and a functioning saddle lift because of the constant up & downs)!
Very great and varied round.
At the end, the Magglingen downhill can be added for dessert if you want to crank back up to Magglingen.
A clear tour recommendation!

We rode the tour on Sunday 17.10.2021. We deliberately started from Magglingen, as the ascent from Biel/Bienne on the road can be safely forgiven. However, the ascent to the tower on a beautiful autumn day with countless day trippers and hikers is a first challenge, as you are sometimes overtaken on the road without consideration. Once you have made the ascent, however, the "beautiful" part begins and, on a clear day, there is a magnificent view of the entire Alpine chain, which alone is worth the effort of the climb. The descent begins right next to the transmitter. However, the first 50m are difficult to ride, but after that the trail offers pretty much everything a biker's heart desires. It alternates between up and down, over pastures with different gate constructions. It is advisable to stay focused, as the typical Jura limestone does not forgive carelessness. You are also rarely alone, as there are a few hikers on nice days, but this has never been a problem. The longer the descent, the fewer hikers you meet and the terrain offers plenty of variety, from rocky to rooty, sometimes flat, sometimes steep. All in all, a highly recommended tour for experienced riders.

The tour is quite something! Especially in spring.
The ascent is worthwhile as the crossing of the ridge and subsequent single trail descent is super beautiful and varied.
The ascent back down to Magglingen is not as thrilling :-)

Very varied tour. We were there three weeks ago. If you are looking for an uphill off the beaten track, you can take a look at the following link:

The trail to Frinviller is quite challenging in at least one place (S3) and there are lots of hairpin bends (in my opinion, it's not absolutely necessary to move the rear wheel, but it doesn't hurt to keep the flow going) and steps, otherwise everything is between S0-S2 and very varied. At the end, we rode through the Bikepark Biel, which was a really cool way to finish.

Rigorous but beautiful tour, especially in spring!

But also in the rain in fall :-)

Super round
You have to do it once.

Just under 60km and 2000 vertical meters from Biel without a railroad line. Beautiful tour, the descent to Frinwillier is a little exposed in places and better to ride in dry conditions.

Great tour, although the ascent from Nods at the latest is only along the asphalt road. The first section from the antenna is very technical but then becomes increasingly smooth.
