Stromer ST-1 Platinum Complete Electric Bike $4,249.00
Given the combined caloric intake needed for recreational riding, competitive cycling, and commuting by bicycle — on a healthy diet — grocery bills easily approach operating costs for a dino-burning cage. On the other hand, modern electric bikes, like Stromer's ST-1 Platinum, cut bio-energy requirements (not forgetting non-renewable, too) and still let the legs work.
Stromer is an innovative Swiss company with five years dedicated to the e-bike and, now backed by BMC, they're making a push onto US soil. The ST-1 Platinum 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 20mph max speed, and close to 3/4 horsepower with 30ft/lbs of torque.
This is plenty to quickly knock out steep climbs, pull a kid trailer — or one loaded with a week's worth of groceries — without breaking a sweat in the heat of summer. The battery is fully integrated into the down tube and is easily removed with the press of a button. This convenient setup allows charging onboard or externally from the ST-1. To maximize range, the gearless 500-watt motor has efficient regenerative braking technology.
Through the programmable digital interface you can choose customizable 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 30/39/50T 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 Platinum Complete Electric Bike comes in 16.5 or 20.5in frame sizes and three colors are available: White, Red, and Black.
