Which i:SY is right for me?

What you need to do is test-ride bikes as many times as it takes! 
This is the only way to find out which i:SY is the perfect match for your preferences and requirements.

First things first: it's important to point out that the basic components are identical on all i:SY models. The difference lies in the various motors, gear shifts and drives (chain or toothed belt).

i:SY S8

Our S8 models with SHIMANO Nexus 8-speed hub gear and easy-care toothed belt drive is the perfect intro to the i:SY world. The i:SY S8 F is equipped with a freewheel. The i:SY S8 RT features a back-pedal brake. Fitted with the harmonious BOSCH Active Line Plus motor and the BOSCH PowerPack with 400 or 545 Wh, our i:SY S8 models are the ideal companion for relaxed trips in the city and countryside alike. 

Our i:SY S8 B models are characterised by that extra-special touch. Supplied with real leather saddle and brown leather handles as standard, it is not only a treat for the hands, but also for the eyes. Brown tyres, an angle-adjustable stem without the need for tools and the i:SY tension belt are also part of the package.

The i:SY S8 K is equipped with the sporty SHIMANO Claris 8-speed derailleur gears and the powerful BOSCH Performance Line motor, making light work of every climb.

i:SY S10




Our i:SY S10 ADVENTURE is fitted with the SHIMANO Tiagra 10-speed derailleur gears. 
In combination with the powerful BOSCH Performance Line CX motor, the S10 ADVENTURE cuts a particularly impressive figure off-road. A SUNTOUR suspension fork caters for added comfort. The off-road equipment is rounded off with the Smart Sam deep-tread tyres, which guarantee the right grip, even on gravel tracks.

i:SY E5



The i:SY E5 ZR is fitted with the SHIMANO Nexus 5-speed hub gear, which was especially developed for e-bikes. Together with the GATES® toothed belt, this makes for an unrivalled duo – clean and low-maintenance. Perfect when loading up the i:SY for holidays, for instance. Our E5 models feature the BOSCH Performance Line and Performance Line CX motor. 
Our CENTURY models are distinguished by the two special colours riviera blue and racing green. They are also equipped with original Brooks components – the brown leather saddle and leather saddle bag. Matching leather handles complete the overall image. 

i:SY N3.8

The N3.8 ZR is our classic. The continuously variable ENVIOLO 380 hub gear is easy to shift even under load, taking the effort out of every unexpected climb. The clean, low-maintenance toothed belt by GATES® bids farewell to squeaky chains – and dirty hands when loading are also a thing of the past. A comprehensive package that ticks all the boxes – and our i:SY lovers agree. 

With the powerful BOSCH Performance Line and Performance Line CX motors, the N3.8 models are ideal for frequent riders and pleasure cyclists alike, on flat or hilly terrain.

As standard, our COMFORT models come with features that enhance the riding experience, ensuring an even more enjoyable ride. These include the suspension seat post from by,schulz and the larger saddle, both of which provide even more comfort. The handlebars with a greater offset and shorter stem create a more upright sitting position. Ideal for all riders who appreciate special comfort. 

i:SY P12



Our new P12 models are equipped with the revolutionary Motor.Gearbox.Unit (MGU) by PINION – a unit that unites gear shift and motor. It not only fits perfectly into our new frame shape, but also gets you wherever you want to go in a breeze. With a transmission range of 600 percent and 85 Nm assistance, it packs a real punch. The highlight of the new frame shape is the integrated quick release!

Thanks to its closed system, the MGU is extremely low-maintenance and practically wear-free – making it unbelievably durable. Gear shift and motor are optimally coordinated for a harmonious riding experience. Gears can also be shifted under load, which is particularly practical during unexpected climbs. With 800 Wh, the Compact Core battery by FIT guarantees maximum range, making no distance too far.
