Which i:SY is right for me?
As a general rule, it's best to try out, try out and try out again!
You will find the right i:SY for you which meets your preferences and requirements.
First of all, you need to know that the basic components are identical in all i:SY models. The difference lies in the different Bosch motors, different gear shifts and drives (chain or toothed belt).
The E5 model series impresses sporty commuters in mainly urban areas with a 5-speed SHIMANO hub gear containing a toothed-belt drive, all developed especially for e-bikes. This series contains the Bosch Performance Line motor. The E5 ZR F CX model boasts the highest-performing Bosch motor. The Performance Line CX is used in this version. The Comfort versions feature a BySchulz suspension seat post and handlebars with a greater offset plus a shorter stem and a larger saddle.
The N3.8 ZR models are equipped with the continuously variable Enviolo 3.8 hub and an easy-care toothed-belt drive. Featuring the dynamic Bosch Performance Line motor, it is optimally equipped for use on flat or hilly terrain by frequent riders and pleasure cyclists alike. The N3.8 B is a real head turner with its brown components and its exclusive urban blue.
