The frame production at Romet across the street from the bicycle assembly is running at full capacity at the time of Bike Europe's visit. The logistic advantages are impressive when making your own frames, instead of sourcing them in Asia, or even on another location in Europe. Still, Romet paints large numbers of made-in-Asia frames, which might sound remarkable. According to Romet, the capacity of frame production is not big enough to meet demand in the assembly. “We want to accelerate the product innovations at the frame factory,” Romet president Wieslaw Grzyb told Bike Europe. “In the future, we want to focus exclusively on the production of e-bike frames, so we can take full advantage of frame production at such a short distance from the assembly lines.”
Frame production operation
All aluminium 6061 used in frame building is sourced in Poland and supplied by two companies only to ensure quality standards are met. “Finding aluminium 6061 with stable quality which matches the specifications was one of the biggest challenges when production started in 2019,” explains R&D manager Jakub Marek. “Today, the production process is fully streamlined. All tube elements are fixed on one single welding table after which the robot makes the welding connections in two steps. All pre-treatment, including laser cutting and hydro forming is done in-house on the same floor.”
For all frame testing the factory is equipped with an in-house testing lab which has many advantages. Of course, all frames are tested according to the EN15194 standard, but with the in-house test-lab, they can easily perform the tests according to different, stricter requirements. For example, the EN15194 requires that all test runs include 5 different tests but to ensure top quality Romet always adds a 6th additional strength test run to ensure quality at the highest level.
