GTF geometry

GTF geometry

The sporty GTF geometry of the STEVENS E-Inception series is fully designed for downhill-orientated performance. A long reach and a slack steering angle give the E-Fully a smoother ride, which has a positive effect on the downhill controllability of the E-MTB. A shorter head tube and steeper seat angle provide more control on steep climbs. Incidentally, GTF stands for Gas To Flat and means full throttle with full control down the mountain.

29/27.5" wheels

29/27.5

A 29" wheel at the front and a 27.5" wheel at the rear ensure even more trail fun and performance on the descent. While the larger front wheel provides more grip, better rollover behaviour and smoothness, the smaller rear wheel provides more space, more acceleration and, above all, more agility in tight corners. The so-called mullet bikes can fully utilise their advantages, especially downhill.

QR15 thru axle

QR15 thru axle

The "15" stands for the axle diameter, the "QR" for "Quick Release" – and together for the most functional method of anchoring the front wheel in the (suspension) fork. The advantages are impressive: high rigidity, precise brake disc positioning and foolproof operation. STEVENS therefore equips all mountain bikes and E-MTBs as well as the highest quality trekking bikes, cross bikes and E-bikes with them. For (E-)MTBs in particular, the installation width has even been increased – from 100 to 110 mm, which is even stiffer.

On/off switch with integrated USB-C charging socket

On/off switch with integrated USB-C charging socket

On the E-Inception models with Shimano drive and the large Darfon battery, a USB-C charging socket on the top tube – ensures that the smartphone, action camera or lighting system are powered for as long as the trail adventure lasts. Riders can also switch the system on and off in a smart and user-friendly way on the top tube.

Block Lock headset with impact protection

Block Lock headset with impact protection

Anyone travelling on alpine trails with their E-MTB demands maximum control. Thanks to its 150° pivot angle and high-quality ball bearing, the Acros Block Lock headset with integrated cable routing ensures that the top tube is optimally protected from impacts in tight bends or in the event of a fall. The fact that this results in fewer crashes in the first place is a further benefit of the impact protection.

Dropper post

Optimum seat height for drive efficiency. Press the button. Saddle down for technical descents. Button ... it could go on and on – and on some technical trails, the seatpost remote is used more often than the front derailleur shifter. Experts in riding fun and safety agree: rarely has an innovation brought such convincing advantages and so few disadvantages (weight, price) as seatposts with infinitely adjustable seat height.

Integrated kickstand mount

Integrated kickstand mount

A practical stand on the rear triangle of STEVENS E-Inception bikes is not a must, but a welcome extra. That’s why our engineers have installed an inconspicuous kickstand mount. The FEQ models come with a kickstand as standard. It can be retrofitted to all other E-Inception models without any problems and without sacrificing heel clearance on complex trails.
