The Greyp G6: Your Favorite New Selfie Stick With Pedals
Their cars accelerate faster than a Tesla, use facial recognition rather than a key, and have frames built entirely from carbon fiber, and now Croatian hypercar manufacturers Rimac Automobili are going mountain biking with the Greyp G6 eMTB.
Rimac’s bicycle division, Greyp Bikes, has been producing high-speed road-going bikes for a few years, but their first foray into mountain biking was introduced as the G6 series in 2019, and models are finally going on sale online.
Following in the Rimac hypercar’s footsteps, the Greyp G6 is as much an exercise in technology as it is an actual mountain bike itself.
Below we’ll take a look at the company behind the flagship tech-bike, the specs on the bike itself, and an overview of some of the absolutely bonkers technology that Greyp has integrated into this full-suspension spaceship.
The Company: A History Of Greyp Bikes
Rimac was conceived back in 2009, allegedly after CEO Mate Rimac blew an engine in his BMW E30 during a race and decided to build an electric powertrain for the car rather than rebuild the existing combustion engine.
The company was formally established in 2011, and shortly thereafter the Concept_One supercar was produced. Rimac quickly garnering media attention with the car by taking a podium finish at Pikes Peak and hiring Top-Gear’s Richard Hammond as a human crash test dummy.
Rimac wasted little time diving into R&D for their planned bicycle division, and by 2013 were already making waves with the Greyp G12, a motorcycle/bicycle hybrid packed with high-tech controls, fingerprint anti-theft authentication, and multiple power modes accessible on the fly.
The G6 line of eMTBs is their latest two-wheeled venture, and is by far the most technologically advanced bicycle of any kind we’ve ever seen.
Before we dive into the tech though, let’s take a look at some specs on the bike itself.
The Bike: Greyp G6 eMTB Models
A full carbon frame, 700Wh battery, and 250W (or 460W) motor with a power output rated at 95Nm of torque are the high-tech bones for an otherwise pretty basic eMTB platform, all technology aside.
The MPF Drive motor is unique to Greyp and the industry as a whole, but boasts advanced features like a constant oil-bath gearbox inside of a water and dustproof housing. It’s fairly untested, but Greyp assures the public its performance is matched only by its reliability.
The G6 features 150mm of suspension travel that comes from a Rockshox Lyrik fork fitted for 27.5” boost wheels, and a Monarch RT3 shock out back provides plush support for your trail riding pleasure.
Braking comes from four-piston Formula Cura 4 calipers on the upmarket models, which are just as high tech as the rest of the bike. These brakes utilize integrated electronic sensors that reduce power from the engine in real-time as you apply pressure to the brake lever.
Not so different from the ABS and traction control functions you get on a $20,000 KTM motorcycle…
The Greyp also comes with a dropper post, but its travel is limited to 100mm due to the frame design.
Ultimately this isn’t likely to be a deal-breaker for anyone interested in the Greyp considering the fact that it’s a casual trail bike first and foremost, and doesn’t have the kind of geometry you’d want on a modern enduro or downhill bike to begin with.
The seating position is high, which makes for easy pedaling uphill, but isn’t exactly confidence-inspiring when gravity takes over.
The Greyp comes in three models, the 6.1, 6.2, and 6.3.
The G6.1 Bold FS is the entry-level model, and starts at $7,899. It gets lower-tier RockShox suspension in the form of a Yari RC fork and Monarch RT shock, as well as two-piston brakes instead of four-piston models.
Inexpensive Blackjack Ready 40 wheels and Nobby Nic tires will ultimately resign the 6.1 to gravel roads and commuting duty for the most part, but you could certainly still manage to have a good time blasting around beginner and intermediate trails faster than anyone else on two wheels.
The G6.2 Expert FX is the mid-level bike, coming in at $8249. Middle-tier or not, the G6.2 looks like the smart buy for more intensive off-road use thanks to DT Swiss 1700 wheels wrapped in Schwalbe Magic Mary tires, whereas both the entry-level and upmarket bikes stick with comparatively flat-prone Nobby Nic rubber front and rear.
The G6.2 has all of the same suspension components as the G6.3, but the restricted motor is still street legal, so you can use it to commute or connect gravel roads without breaking the law.
The G6.3 Rebel FS starts at $8,999, and gets an “unlimited motor” which boasts a full 460W output and is capable of speeds up to 28 miles per hour.
There are some other premium parts as well including Crank Brothers wheels, grips, and pedals, but the G6.3 suffers from the same relaxed frame geometry as the other models, so keep that in mind if you’re considering ordering one yourself.
Technically the motor on the G6.3 makes it an “offroad use only” bike, but if we’re being honest, you’d have a harder time finding a police officer to write that ticket than you would eating your Greyp with a fork and knife.
And if money is truly no object, there’s also a limited run of 100 “G6.X Limited” models, which start at $17,000, and feature some of the best components known to man including Ohlins front and rear suspension, BikeAhead carbon six-spoke wheels, and a wireless SRAM AXS dropper post and shifter.
The G6.X is the only G6 model to feature slightly more aggressive geometry, but somehow they still choose to spec the premium model with Nobby Nic tires front and rear. Go figure.
The G6 is nothing if not a technological marvel, and while its downhill prowess is nothing to write home about, its list of high-tech features reads like a novel.
The most striking of which is surely the two clearly visible wide-angle 1080p cameras mounted at the front and rear of the bike, which can capture photos remotely, live stream video of your ride, or record videos of your buddies riding like a stationary video camera.
All of this is available through the Greyp app, which is the other serious standout piece of tech on the G6.
The Greyp app is constantly connected to your bike, and handles all of the navigation duties, video controls, and status readings on the bike itself, while also serving as a high-tech anti-theft system.
This is achieved via wireless data transmission from the bike itself, allowing owners to track the GPS position of a stolen bike, remotely record live video or photos of the bike’s current location, and even remotely disable the bike if needed.
Of course the G6 also has a secondary TFT screen in case you forget your phone or choose to ride without it in the cockpit.
This 3” non-reflective display is referred to as the Central Intelligence Module, or “CIM” for short, and reads out all the essential functions like speed, cadence, battery life, and trip distance.
The CIM also houses the eSIM card, allowing the module to provide a constant 3G internet connection and serve as a WiFi hotspot to communicate wirelessly with your phone.
As you might suspect, that constant connectivity also means that the G6 will receive automatic wireless updates to the software as Greyp rolls them out. It also allows your bike to send notifications directly to your phone on its charging status, location, and software.
