Interestingly Trek have opted for Sun Ringle Duroc 40 rims but as we found out proved super durable. We love the Dropline seatpost and the Evoke 2 saddle is good for all day action. SRAM Guide RS are strong but we wonder whether the new Guide RE brakes might have been a better option for fast and lengthy Alpine descents. 200/180mm rotors are fitted and essential on a bike like this.

The Powerfly LT uses the Bosch Purion display, which gives all the detail needed – battery life, power mode, speedometer and service detail. It’s a more compact design and easier to use than some other models and a sight we’re seeing more of on 2017 model e-bikes.

The Bosch motor requires a slightly different technique to get up and over the steeper stuff than the Brose equipped Specialized Levo but crucially, on longer climbs the Trek keeps bubbling away and means lighter legs as you approach the top of the crazy climbs. Remember we’re talking steep climbs here, the ones that get the heart rate into the maximum zones rather than spinning fire roads, a place where there is not much between the bikes. This Bosch equipped bike is quiet under load, unlike the Brose system on the Specialized Levo.

A low bottom bracket, correct head angle and a good front/rear centre balance means the Powerfly LT is very confident when descending. The Trek’s geometry is inspired, the shock tune correct and the bike always feels planted. This bike is fully brilliant. It makes everyone who has ridden it very, very happy.
