Who invented it? The Swiss E-Fully with the snake battery

The Swiss bike manufacturer Bergstrom is unleashing a veritable firework of innovation for the second year of its existence: e-mountain bikes roll into the portfolio, which feature a unique battery solution with magnetic suspension as well as an elaborately manufactured frame, the fully with VPP suspension system with 140 millimeter stroke.

In the summer of 2016, the surprise was great when Komenda - the manufacturer of the Cresta and Ibex bikes - drew the curtain on a new bike brand in Apple style at the end of the presentation. The prologue for the new Bergstrom brand was trekking-oriented e-bikes, and freshly designed e-mountainbikes are set to cause a sensation in the second year.

Three chambers for the down tube

A Shimano E-8000 power unit is on board the e-mountain bikes, which has won considerable praise in almost all tests. The drive also shines on the Bergstrom APVs (the abbreviation stands for Alpine Trail Velo) with small installation dimensions, a narrow Q-factor and a sporty riding feel thanks to good sensors.

The Swiss bike manufacturers have fitted a charging socket above the Shimano motor so that the battery can be charged when mounted. Above this electrified motor bridge is a good piece of innovation in two ways: Firstly, the aluminum down tube. With a three-chamber layout (this design also ensures frame rigidity), this profile offers space on the left and right
space for easy cabling of shifting, braking and drive components
.

The flexible battery

The battery is located in the middle of the down tube channel and stands out with its innovative solution. The 500 Wh battery, known as the Snake Pack, is divided into six parts and can be rotated between them. The result is a battery that can be pulled out of the down tube with a slightly firmer tug and, thanks to its flexibility, wriggles out of its habitat, which is protected from the elements, so to speak. The fixation by a magnet and the three-chamber down tube should ensure that the battery sits absolutely vibration-proof in the bike.

For the 2018 model year, Bergstrom is sending an 800 and a 700 series of the new APV to bike stores, which can be ridden with 27.5 Plus or 29er tires. The 800 series comprises three versions of the full-suspension bike, which comes with 140 millimeters of travel. With the 700 series, Bergstrom launches the e-mountainbike hardtail line with two model variants. Further details on the bikes can be found in the photo gallery.
