About Grundler Bikes
Grundler Bikes is a personal project by Mike Gründler, an engineer and bicycle enthusiast from Zurich. The company develops and sells the e-bike Grundler ONE – a minimalist urban e-bike with a maintenance-free carbon belt drive, torque sensor, hydraulic Tektro disc brakes and a removable battery with a range of up to 100 km. The small series of 50 bicycles is produced in cooperation with a partner company in Portugal; quality control, final assembly and test rides are carried out by Grundler himself in Zurich. The focus is on repairability, durability and simple, easy-to-maintain designs. After purchase, Grundler Bikes offers maintenance, repair in cooperation with bicycle shops, home test rides in Zurich and a two-year warranty.
