Very few bikers will be familiar with BESV. Behind the young e-bike brand is the Taiwanese electric giant Darfon, whose batteries are being installed in more and more e-bikes with Shimano drive systems.

The aluminium frame of the BESV TRS 1.3 houses the 630 battery and Shimano's EP8. At the front is the massive Rockshox Domain suspension fork with 38 mm stanchions and 160 mm travel, while the rear suspension delivers 150 mm. Paired with the 29er wheels, the bike lands in the centre of the all-mountain sector of our test group.

The sizing of the frame is less clear. S, M and L are available. Medium is recommended by the manufacturer for riders between 174 and 187 cm tall. So a test bike in M ended up in our editorial office, while the other manufacturers tend to recommend Large for this size.

In fact, the bike is very short in M, but the seat tube is relatively long. The bike is correspondingly compact. On the trail, the short bike has a rather lively character. However, it doesn't want to whizz through the terrain with real agility, which is prevented by the high weight and the lack of counter-pressure in the suspension. The bottom bracket is very high, so you don't feel well integrated into the bike.

The Domain fork stands out positively, responding sensitively, parrying even big hits confidently and giving the bike very good control. In comparison, the rear suspension lacks counter-pressure and reserves. In rough terrain, even with a rather firm setup, we suffered a few punctures. The TRS 1.3 performs better on the climbs, where it masters even difficult and steep sections well.

The spring mechanism, which is supposed to prevent the battery from falling out when it is removed, did not work on our test bike. Be careful when replacing the battery!Photo: Adrian KaetherThe spring mechanism, which is supposed to prevent the battery from falling out when it is removed, did not work on our test bike.

Conclusion by Florentin Vesenbeckh, deputy editor-in-chief of EMTB:

BESV combines a good drive with decent equipment. However, the chassis was not fully convincing in demanding terrain. Be careful when choosing the size!

Florentin Vesenbeckh has been on a mountain bike since he was ten years old. Even on his very first tour, he focussed on single trails - and even after more than 30 years in the saddle of an MTB, these are still the quintessence of biking for him. He spent his youth competing in various bike disciplines and later his cycling career was characterised by years as a riding technique coach. Professionally, the experienced test editor now focusses on e-mountainbikes. In recent years, the qualified sports scientist and trained journalist has tested over 300 bikes and more than 40 different motor systems in the laboratory and in practice.
