The dream figure doesn't fall from the sky. A lot of sleep, discipline and hard training are the price for narrow hips, round bums and a six-pack. A similar dilemma is currently plaguing the e-bike community. On the one hand, we want more battery capacity for long-lasting touring or trail fun. On the other hand, no-one wants to lug the extra weight of the bulky energy source to the summit. Our tests confirm this development. 25.1 kilos: This is how much the touring bikes around 4500 euros weighed in EMTB 1/21 average. This weight problem still separates many mountain bikers from XXL touring fun with a large battery.
But once the Bulls Sonic Evo AM SL-1 had passed our lab test, hope arose. The key data: 750 watt hours, full carbon frame, 29 inches and a total weight of 21.5 kilos - all for a price of 5199 euros. This means that the newcomer fulfils everything you could wish for in an e-mountainbike. The new touring fully from the ZEG brand thus undercuts the competition from EMTB 1/21 by 3.6 kilos! At a similar price level and in view of the high battery capacity, this is a record-breaking achievement. But how is this possible?
Why not free of charge? Because quality journalism has a price. In return, we guarantee independence and objectivity. This applies in particular to the tests in EMTB. We don't pay for them, but the opposite is the case: we charge for them, namely tens of thousands of euros every year.
