About Stromer
Stromer was founded in 2009 in Switzerland by Thomas Binggeli, who set out to build a different kind of electric bike: one fast enough to replace a car commute. The result was the speed pedelec, a Class 3 e-bike that assists up to 28 mph. Stromer builds every model around that idea.
Stromer puts the motor in the rear hub and the technology in the frame. Its bikes run powerful rear-hub motors, large integrated batteries, and the OMNI connectivity platform, which adds GPS tracking, keyless locking, and theft alerts through a phone app. The bikes are heavy, fast, and built to handle daily high-speed mileage.
Stromer’s lineup is five speed pedelecs, all built in Switzerland. The ST1 is the entry point, the ST2 and ST3 are the daily-commute workhorses with Pinion gearboxes and belt drives, the ST5 is the tech-loaded flagship, and the ST7 is the long-range model with a 1,440Wh battery. Every Stromer is a commuter bike first.
Most popular Stromer models
Every Stromer is a speed pedelec, so the lineup is organized by range, power, and technology rather than by discipline. The ST1 is the reliable entry model with a 500W rear-hub motor and an 814Wh battery. The ST2 adds a Pinion gearbox and Gates Carbon belt drive for low-maintenance commuting, and the ST3 steps up gearing and range for high-mileage riders.
At the top, the ST5 is the flagship, packed with Stromer’s latest motor and connectivity technology, and the ST7 is the long-range model, with a 1,440Wh battery good for up to 160 miles. These are fast, expensive bikes built for daily car-replacement commuting, and their value plus their theft appeal is exactly why stand-alone commuter bike insurance matters for a Stromer.

Stromer's Warranty: What It Covers and Where It Stops
Stromer warrants its Stromer-specific components against material or production defects. Five terms decide what that is worth to you.
Three years on bikes activated from September 1, 2025
The ST1, ST2, ST3, ST5, and ST7 carry three years when activated on or after September 1, 2025. Bikes activated before that date carry two years, except the ST2 with belt drive from production year 2020, which carries three.
Ten years on the frame
Irrespective of model, the frame is warranted for 10 years on bicycles manufactured as of 2017, the bikes with 27.5 inch wheels. Bicycles manufactured up to and including 2016, with 26 inch wheels, carry 3 years on the frame.
Battery: 75% of capacity within 2 years
Battery capacity is determined by a capacity test conducted by Stromer at the request of a Stromer retailer, and the result of that test is decisive. The State of Health shown in the Stromer app is indicative only.
Claims go through your dealer, in the US too
Claims are submitted to an authorized Stromer dealer with the original receipt of purchase, and the warranty period runs from the date of sale, registration, or activation, whichever comes first. Stromer is not supplying new bikes to the US or Canada until further notice, and it states that dealers there continue to honor warranty commitments.
Defects only: the consequences of a fall are excluded
The warranty extends exclusively to Stromer products that exhibit a material or production defect, and it lists the consequences of a fall among its exclusions. Those are the losses a Velosurance policy is built for.
Summary of the Stromer warranty provisions and limitations of liability, reviewed September 17, 2026. Applies to new Stromer products, on presentation of the original receipt of purchase from an authorized Stromer dealer, under the provisions dated February 11, 2026. The version valid at the time of purchase is decisive. The manufacturer decides every warranty claim, and its full published terms govern.
