Stromer is an innovative Swiss brand whose roots are in e-bike development, and they are now backed by BMC and being introduced on US soil for the first time. And while e-bikes occasionally garner a few raised eyebrows from self-propelled riders, in truth, they are just another way in which any rider is able to enjoy the freedom and joy of riding on two wheels.
The ST-1 Elite uses Stromer\'s smart modular design and is equipped with the ST522 Li-Ion 36v battery and Mountain 33 motor. This combination gives the ST-1 a range of 25 to 56 miles, a 20 mph max speed, and close to 3/4 horsepower with 30ft/lbs of torque. The Li-Ion battery is fully integrated into the down tube, and it is easily removed with the press of a button. This convenient setup allows charging onboard or externally. To maximize range, the gearless 396-watt motor has efficient regenerative braking technology.
Through the programmable interface you are able to customize settings and monitor ride information such as: battery charge level, current speed, distance, and elapsed time. The intuitive interface also allows you to easily engage regenerative braking. For reliability, efficiency, and quiet operation, the ST-1\'s Mountain 33 rear-hub-located, direct-current motor uses a brushless design that rides on industrial ball bearings.
For components, the ST-1 uses Shimano Sora for the drivetrain with a 42t FSA Tempo crankset and 11-32t cassette. Brakes are Magura\'s MT2 for excellent power and modulation, while Schwalbe Big Ben tires ensure a supple ride and positive traction on broken surfaces. A BMC carbon fork helps dampen vibration, while an alloy bar, stem, and seatpost help keep the Stromer ST-1 light and nimble.
The Stromer ST-1 Elite Complete Electric Bike comes in 16.5 or 20.5in frame sizes and two colors: Black and White.
