Hartje i:SY DriveE S8 ZR - Easy & Fold/Compact Very Good, Tour Good

The original compact bike, and like many successes often copied. But the I:SY still impressed test riders with its versatility in use: as a family bike, a holiday bike, or a young person’s bike which grows with them…

How you see the I:SY depends on your point of view. For a campervan owner it’s the perfect bike: it takes up hardly any space in your mobile home’s ‘garage’, but it’s still an uncompromised, full-performance pedelec. And for a family, it’s a one-for-all solution across a very wide range of rider heights because of its easy adjustability. For young people it’s also ideal, because it can grow with them for many years. So it’s incomprehensible that the seatpost isn’t equipped with a quick release: a steel cable could fitted inside to protect it against opportunist theft. With a payload rating of 118 kg this compact bike should allow carriage of plenty of luggage, and for this purpose there are lowrider rack mounts on the fork, and several carrier rack options for mounting on the headtube. Test rider verdicts: “Pin-sharp and agile, a nippy bike with a great drive system, good assistance in all circumstances, the belt drive is a dream, and user controls – all superb.
