What are the differences between the various Tender models?

In this category size does matter. The Tender 1000 has the most “modest” platform size of the range. With a length of 142cm and a width of 95cm you will fit through most of the city’s bike lanes. The 1500 and 2500 are both a bit wider and longer. Most of the build-ups that are available for the 1000 are also available for the 1500.
