XXL? What does it stand for?

XXL is synonymous with even greater load and even more flexibility. The i:SY XXL models offer excellent ride comfort on any terrain with a load capacity of up to 180 kg total weight. They are also eminently suitable for tall people up to 2.10 m. XXL models can carry loads too: All our i:SY XXL models are equipped with a front pannier rack.

In terms of frame geometry, the XXL has been primarily developed for tall people (up to 210 cm). The seat tube, top tube length, wheelbase and tube diameter have been adapted accordingly and also designed for a greater load. A large bike with small wheels! Shorter riders who weigh more than others (115–150 kg) can also use the XXL where required. However, an adjustment is needed for such riders. A shorter stem and handlebars curved further backwards are already incorporated in the XXL Comfort model. Our advice: you must take a test ride without fail! Incidentally, all XXL models are fitted with our front carrier as standard.


The E5ZR model series impresses sporty commuters in mainly urban areas with a SHIMANO 5-speed hub gear containing a toothed-belt drive, all developed especially for e-bikes. It is fitted with the Bosch Performance Line motor. The electronic Di2 version allows the rider to switch gears using a button or ride in automatic mode. The Bosch Performance Line CX is used in this version.


Comfy sitting position, wider Ergon grips, comfortable, wide saddle and pleasant suspension integrated into a clear, modern design. And all this at a low extra cost. All our Comfort models are fitted with Stuttgarter handlebars, wide Ergon grips, a Comfort saddle and a BySchulz suspension seat post.
