With the small P12 ZR, i:SY is currently the only compact e-bike with a Pinion motor transmission unit. This promises numerous advantages.

At the last Eurobike there were numerous new e-bikes for the 2024 season, but a new drive system stole the show from many of the innovations. We’re talking about the Pinion motor transmission unit (MGU). This is also used in Bulls’ new S-Pedelec.
The Pinion MGU is currently considered by some to be the holy grail of drive concepts. The engine and transmission form a combination here. An almost maintenance-free rear derailleur sits in a housing together with the electric motor.

In contrast to derailleur shifting, electrical shifting with a Pinion gearbox also works when stationary and (with minor interruptions) even under load. Pinion bikes are often available with a belt drive, which further reduces maintenance requirements. The P12 ZR presented here also comes with a belt drive instead of a chain.
The product name already suggests it: the manufacturer uses a Pinion gearbox with twelve switching stages. The twelve gears offer a development of 600 percent. Together with the engine’s generous torque of 85 Newton meters, even steep mountains can be conquered.

In contrast to the Fiido Titan we last tested (for the video review), you can use the i:SY P12 ZR within the completely legal framework. The motor supports your pedaling movements in accordance with the law up to a maximum speed of 25 km/h. The battery capacity is pleasingly generous at 800 watt hours.
Other practical details include the frame-mounted luggage rack, the factory-installed mudguards and the LED lighting. There is also an integrated frame lock from Abus.
Price, availability and alternatives
The i:SY P12 ZR is now available to buy from the manufacturer at a price of 5,999 euros. However, with a weight of 25 kilograms, the compact e-bike is quite heavy. If you can do without the Pinion drive, you will find an alternative in the i:SY Skyfly E5 ZR F for 5,599 euros.
The e-bike looks very similar to the P12 ZR, but offers a Bosch mid-motor, 5-speed hub gear and weighs only 18.8 kilograms thanks to the carbon frame. We will introduce you to other e-bike innovations of the year here.
