Swiss manufacturer Stromer, an electric-bike brand of BMC, recently launched its ST1 pedal-assisted electric bike in the United States. The 500-watt ST1 was designed to blend function, versatility and style into a commuter-friendly bicycle.
Switzerland has been making a name for itself in the transportation industry of late. Although a Stromer slogan reads, "Because the Swiss don't build cars," the Swiss have proven that they can and do build cars, showing off one of the more impressive supercars we've covered in recent months. We've also seen several interesting cycle designs, including the BMC-Lamborghini collaboration and the Circleboard scooter.
Like those models, the Stromer ST1 appears to include the meticulous attention to detail that has turned other Swiss industries (e.g. watchmaking) into legends. The bike's girthy downtube conceals a Samsung lithium-ion battery that can be removed at the push of a button or charged directly on the bike. The battery sends its power to the rear-mounted 500-watt brushless hub motor, providing up to 30 mph (48 km/h) of speed and 50 miles (80 km) of range. Regenerative braking helps keep the battery powered up as long as possible.
To ensure that the ST1 meets the diverse needs of riders, it uses four different ride modes, which balance rider input and motor power. Riders can select the ride mode from the three-button handlebar computer, which also shows information about battery power, speed, distance and time.
Last month, Stromer announced the launch of two models on the United States' market. The 9-speed ST1 Elite has a recommended retail of US$3,499 and uses the 500-watt "Mountain 33" motor, which offers up to 29.5 lb-ft (40 Nm) of torque. The bike is capable of speeds up to 20 mph (32 km/h) and has a range between 20 and 40 miles (32 and 64 km).
The $3,999 ST1 Platinum packs 27 speeds and a "Power 48" motor that pushes the bike to up to 30 mph (48 km/h) and between 25 and 50 miles (40 and 80 km). It offers up to 22 lb-ft (30 Nm) of torque.
Both bikes have Shimano drivetrain components, Magura MT2 disc brakes, Schwalbe BigBen puncture-resistant tires, and rigid carbon forks. The Platinum is available with an SR Suntour suspension fork.
While the Elite is a standard urban commuter, the Platinum model is classified as an off-road vehicle not meant for public roads, highways or streets due to its extra power. Stromer goes so far as to provide a disclaimer that using it on public streets could result in serious injury or death.
Stromer opened a new 47,000 square foot (4,400 sq m) production facility in Oberwangen, Switzerland in February. The new plant will handle all of its international production in the future.
