2025 Greyp

G6.6 PRO

If you are a modern e-bike brand that was originally part of Rimac Automobili, the high-end electric sports car company, and then you are bought by Porsche, chances are you’re not making the e-bike equivalent of a Ford Fiesta. It’s likely you’re producing a super e-bike, with the latest tech and an impressive trail presence. Greyp is that company, but the real question is if the G6.6 is that e-bike? Need to know: E-bike from the same marque as Porsche, with 460W MPF motor with easily removable 700Wh Porsche battery Full carbon frameset with single pivot suspension Mullet design with 160mm Formula Selva fork and RockShox Monarch RTS shock pumping out 150mm of rear travel. Front and rear brake lights with built-in twin 1080p@30fps cameras Most supercars come with a cool carbon fibre skin and that’s also the case here. The Greyp G6.6 gets a full high-modulus composite chassis, which is bolted together with stainless-steel hardware. You also get a couple of nice details like a chain device, a rubber mudguard behind the BB to keep dirt off the main pivot bearings, a bonded chainstay protector and a large bash guard to shield the motor. The motor in question is a Taiwanese made MPF unit, but Greyp is offering two options on the G6.6, a 6.0c which is limited to 25kph and the 6.0s motor featured here, which will run to 45kph. Obviously the latter is derestricted, and when we put that to the UK importer it told us that the 6.0s is for competition and off-road use only. Peak power of the motor is 460w and powering the motor it is a custom 700Wh (Li-ion) Porsche battery. And this is where the bike gets interesting. Rather than being housed inside the downtube, this battery bridges the down tube and seat tube, which looks odd, but there’s a method in the madness, because removing the battery literally takes seconds. There’s a little lever on the front that you flip up and the whole battery pops out without needing a tool or a key. Handy for racing or charging indoors, right? Controlling the motor is a CIM (Central Intelligence Module) housed in front of the custom 50mm stem. This functions like a standard display, albeit it a large one, and it has the trip info, battery and assist levels and you can toggle through the displays in the usual way. However, if you download the Greyp app onto your Android or IOS phone you can mount your phone to the screen using the silicone attachment, and it becomes a smart dashboard. You can then use the mini joystick to access a ton of ride info including cadence, an optional heart rate monitor function and a navigation mode that lets you record your rides. The bike even has built-in 3G, so you can see its location and use the app’s security feature to immobilise it if needed. The on-bar remote lets you toggle between five assistance levels, including a really powerful walk …Continue reading »
