The components partnered with the stiff PowerTube frames of the STEVENS Pedelecs E-14 and E-11 are carefully selected for both their perfect integration compatibility with the frame and their performance. Both models boast gear hubs with built-in Bosch motor. Powered by Rohloff E-14 and Shimano Alfine 11 Di2 hub for quick gear changes through the ideally stepped gears that’s easy on battery use.
When you push the gear-changing button on the handlebar, the electronic control of the Bosch Performance CX reduces power on the drivetrain and switches gears within 180 milliseconds. When you push and hold the button a little longer, the Rohloff hub will immediately shift three gears up or down.
Yet another perk you’ll love is how the system automatically shifts to an easier gear when coming to a full stop. That way, when the light turns green, you’re quickly and easily back up to speed. Pedalling and motor power are transferred by a silent and maintenance-free, efficient drive belt from Gates that gets you more mileage per charge.
Busch+Müller’s 80 Lux-bright LED headlight IQ-XMF will shine brightly straight through to the end of your tour, well past sunset. When high-beam mode is activated, amazing 120 Lux illuminates the whole road ahead of you. The Shine Evo tail light – nicely integrated into the Racktime pannier rack - interacts with the brake: It lights up just like a car’s tail light when the Magura MT5N-e brake levers are pulled.
Taking the edge off of hard bumps to the frame’s rear triangle is the Cane Creek Thudbuster seatpost which adds that extra level of comfort to your ride. Helping with navigation when needed is the smart Bosch Nyon display.
The STEVENS E-11 also features electronically enhanced shifting comfort: The silent and smoothly accelerating Active Line Plus motor works perfectly in unison with the Shimano Alfine 11 Di2. You can monitor its every move via Bosch Intuiva display. The E-11’s Gates carbon drive belt further adds to the bike’s comfort, safety and pleasure – as does its Shimano Deore M6000 hydraulic disc brakes and Busch+Müller’s bright (70 Lux) IQ-XS LED headlight.
Frame Integration – more than just the PowerTube battery
The newly developed frame of the E-14 and E-11 not only houses the 500Wh battery inside the down tube, but its dropout supports the pannier rack attached to the frame. It’s done using a U-shaped strut that runs below the mud guard. Due to this unique construction, the rack is 20% stiffer than a conventional one. Also, the opening in the frame, necessary for removing the drive belt, is neatly integrated into the chainstay (instead of in the right seat stay). Adding to the frame’s strong design is a charging port integrated into the seat tube.
