Ten years after I bought my travel bike, I wanted to be able to ride more off the beaten track (and surfaced roads) and to start with mountain biking.
As I couldn’t find what I was looking for in Geneva cycle shops, I searched the web and decided to go for a BULLS Copperhead 3. This model wasn’t available in Switzerland, so I took the train to Germany, near Basle, to buy it (Radsport Bieg, Zeppelinstr. 40, D-79540 Lörrach Stetten).
This hardtail bike weighs 11.8 kg and is really manageable in the terrain. You can view a slideshow with other images here.

I’m very satisfied with this bike, after ten years and over 56’000 km (update March 2021), of which a great part has been ridden on mountain trails and single tracks. The only lower quality parts were the Formula RX disc brakes, which I got replaced with Shimano XT.
The brand is familiar with MTB races podiums : riders belonging to the BULLS Team won the Verbier-Grimentz Grand Raid in 2010 (Karl Platt) and 2011-2013-2014-2016-2019 (Urs Huber).
I found at Veloplus a carrier that has been especially designed for MTB : Strela, art. number 1002445 (new model is different from the one I bought in 2010).
Please, note that the original set up may not be “rigid” enough when heavily loaded, for example with two full 20 liters Ortlieb panniers. That’s why we had to improve it together with Mathieu of Viscacha Bike cycle shop. Now, I can convert my MTB into an all-season freighter in just 10 minutes !
The BULLS Copperhead 3 with 27.5″ wheels is still available in 2020 (see their catalog). Sold 1050 Euros in Germany (minus 11% of VAT if the bike is exported to Switzerland), it represents a valuable European alternative to the bikes of the major American brands.
