Greyp G6 – features, spec, weight, geometry
Before we get to the traditional hard facts of the Greyp G6, we’ll first take a look at the electronic components and features.
At the heart of the bike is the CIM (Central Intelligence Module) which is integrated into the bike’s cockpit and is responsible for connecting the various sensors with the motor. Bringing it all together is Greyp’s Robot Operating System (ROS), a software framework for personal robots.
With a 3G-module and an eSIM, the bike is permanently connected to the internet in over 140 countries – thanks to a partnership with T-Mobile (Hrvatski Telekom), the internet connection is completely free of charge until September 2022. To wirelessly have the bike updated online is also made possible by the internet connection.
Regarding connectivity, Greyp has pulled out all the stops in processing and streaming the data. For the security protocol or the “handshake” when your smartphone connects with the bike, the Croatian company is relying on Bluetooth 4.2. The primary communication between the bike you smartphone takes place via WiFi and video gets streamed via a USB-C cable.
The app forms the basis of most of the smart functions like artificial intelligence or augmented reality, collecting data and then evaluating and displaying it, including navigation, range calculations and fitness tracking. We’ve only been able to test the beta version of the app, so we haven’t been able to test the promised features.
Disconnected from the USB-C cable, the app turns into a remote control: send your bike text messages, check the charge level, adjust the support modes, remote camera access to see what’s going on around the bike when you’re not there, an alarm that’s triggered as soon as the bike is moved, and a kill-switch to completely shut the bike down in case someone has stolen it.
Currently, the app is only available for Android, an iOS version is said to be released by 2020 seeing as Apple is a lot stricter and more complex with regard to accessing to data and the interfaces. Generally speaking, the interfaces, protocols and security is a big topic at Greyp.
Despite all the connectivity and digitisation, a bike is still made up of mechanical components that play a very important role.
Greyp relies on the Austrian-Taiwanese brand MPF for the motor, which is in the same league as Brose and company with a rated power output of 250W and 95Nm torque, trying to set itself apart from the competition with an oil-bathed metal gearbox and a water and dustproof housing. While the MPF motor is no lightweight, the metal gearbox with its 200 ml oil bath makes it very quiet, almost vibration free and low maintenance. MPF, by the way, stands for “More Power Feeling”. Besides the performance of the motor, another reason Greyp decided on the MPF motor was the fact that they were given access to all of the software and security protocols. Making software updates via their wireless network (OTA) possible for the motor too.
The Greyp G6 is available in three sizes (S, M, L) and three models with prices range from € 6,500 to € 7,500. The bike we got to ride, the Greyp G6.2, will set you back by € 7,000 and comes with a SRAM EX1 drivetrain, DT Swiss H 1700 Spline wheels and 27.5 x 2.8″ Schwalbe Magic Mary tires. You’ve got a 150 mm travel RockShox Lyrik 27.5″ Boost Debonair fork and a Rock Shox Monarch RT3 shock at the back, also offering 150 mm travel.
The four-piston Formula Cura 4 brakes are outfitted with electronic brake sensors that gently cut out the motor when breaking. Because of the short seat tube necessitated by the design, they’ve had to spec a KS SHOCK LEV-DX dropper seat post with a mere 100 mm. Weighing in at around 25 Kg, the Greyp G6 is no featherweight.
As futuristic as the software and the electronics are, so conservative is the geometry. The rather steep head angle (67°), the very short reach (Size M: 415 mm) and the long chainstays (480 mm) will already have you guessing that this definitely isn’t a trail rocket for aggressive eMTBers. According to Zvonimir Sučić, it’s not meant to be either. The Greyp G6 is aimed primarily at a new target group and less experienced riders, making them feel comfortable as soon as they get on the bike.
Greyp G6: the models in detail
The Greyp G6 is available in three models ranging in price from € 6,500 to € 7,500, with not much separating them. All bikes have the same software and the same tech features. Considering the technology, the 700Wh battery and the beautifully designed carbon frame, the pricing of Greyp bikes is very reasonable.
The bike we tested, priced at around € 7,000, the Greyp G6.2 Expert FS is the best-specced model for trail riding – the wide Magic Mary tires and sturdy DT Swiss Spline wheels provide for a secure footing.
The Greyp G6.1 Bold FS is the entry-level model and costs € 6,500: if you mostly ride gravel roads and easy single-track, you should come right with the affordable but puncture prone Schwalbe Nobby Nic tires and the cheap wheelset. The RockShox Yari fork is cheaper compared to the RockShox Lyrik on the Greyp 6.2, though it still performs brilliantly.
The Greyp G6.3 Rebel FS is the most expensive model in the lineup and could be described as a “fashion bike”. One of the key features is the unlimited motor, meaning that the bike isn’t street-legal without the registration plates required by s-pedelecs. In terms of the componentry, more attention was paid to the looks than the performance. The narrow 720 mm handlebar is a bit of a surprise, seeing as this is the “fastest” Greyp G6 model available.
