Schwalbe Eddy Current: Uncompromisingly geared to e-MTBs

Schwalbe Tires (Germany) - Schwalbe’s new “Eddy Current” is the first MTB tire specifically developed for e-MTBs – for all mountain, enduro and gravity. With radical technology and innovative scale sizing he transfers the e-power into the ground. For his new technology, Schwalbe’s new E-Bike specialist has won the renowned Eurobike Award 2018, being the only awarded tire this year.

Schwalbe’s new Eddy Current is certainly whipping up a storm: It enables relentless uphill and downhill cycling, thrives on powerful acceleration and makes the most of both technical trails and free-flowing cycling. It’s all about pushing the new possibilities to their limits while staying fully in control, of course. “Bikes like these weigh 22 to 25 kilos and the torques acting here, at up to 75 Newton Meters, are almost as high as in motocross bikes. Due to the greater forces, we’ve borrowed from trial and motocross tires; things like the sturdy lugs, more rubber and greater widths,” sums up Carl Kämper, Schwalbe Junior Product Manager MTB Tires. “Added to this is a radical size concept with different wheel sizes on the front and back for maximum performance.”

Front 29 x 2.4 inch, back 27.5 x 2.8 inch is the ultimate stratagem. The large 29-inch front tire, Eddy Current Front, provides direct steering properties and better roll-over behavior than smaller tires. With its open tread and aggressive lug layout, Eddy Current not only brakes and accelerates energetically, it can also be controlled precisely. The additional power of the motor comes into play on the rear wheel. For this, the tire needs the appropriate potential: it must grip deeply into the ground when braking and, even from a standing start on steep ascents, it must be able to convert the full power of the motor into propulsion. The large contact patch of the 2.8-inch wide Eddy Current Rear with its sturdy center blocks supplies the necessary traction. As a Plus tire, it also has good damping characteristics automatically.

Thanks to the sturdy shoulder studs, it remains safely on track when cornering, enabling riders to explore their own limits to the full.

The conclusion:

The two tire sizes combine their advantages to produce a coherent overall concept. The visual differences in size are nothing like as extreme as expected. The larger outer diameter of the Plus tire on the back blends very well with the 29-inch front tire. There are some bikes that already use this size concept. Carl Kämper says, “In future, we will also be bringing out a 27.5-inch front wheel tire and a 29-inch rear wheel tire.”

Sturdy blocks:

The lugs are around 20 percent larger than in the Magic Mary for example. The result: greater stability, more traction and longer service life. “Block squirming”, sideways bending of the block, is practically impossible which means that the tire reacts very directly and responsively to the cyclist’s actions. The distinct grooves in the center block and the lateral lugs are also new. They intensify the properties of the blocks and assist propulsion and braking traction as well as steering control.

Addix Soft Compound:

This compound provides the best overall package for Eddy Current. Rubber compound and tread work together perfectly. While very good grip and optimum damping characteristics on the shoulder studs make the tire controllable, the compound in the center rolls easily and has a long service life despite high torques.

Super gravity carcass:

Schwalbe equips Eddy Current with its most sturdy carcass. Five layers of fabric on the tread and four on the side wall reliably protect against punctures and snake bites. They won’t let their riders down even on extreme descents. An Apex and the SnakeSkin side wall provide additional protection. The tire is also Tubeless Easy. And: as its tread is not directional, it doesn’t matter which mounting direction you choose – a great relief in these Tubeless times.

At Eurobike, the German bicycle tire specialist has not only launched the innovative Eddy Current, but also offered with the new Energizer Plus and the road racing tire Schwalbe E-One the first complete tire range for e-bikes in all relevant segments. With these, along with the new dedicated website and catalogue, Schwalbe is now placing a strong emphasis on e-power. The new tires will be available in the specialist trade from fall 2018.
