Greyp’s G6 E-Bike Adjusts Assistance Based on Rider’s Heart Rate

By Tierney King | March 20, 2019

The Greyp G6, an e-mountain bike, was revealed in Zagreb, Croatia, and different from other electric bikes, the Greyp G6 can monitor a rider’s heart rate and adjust the bike accordingly.

The G6-pedal assist bike focuses on using smart connectivity to monitor a person’s heart rate and other elements while riding.

“Unlike traditional bike manufacturers that are basically combining push-bikes with electrical components, we have developed the bike around an electrical drivetrain, a bunch of sensors and advanced connectivity,” Mate Rimac said during the launch, according to New Atlas.

“The system features and eco-system that we are showing today are much more important than the bike itself. I believe that we succeeded in combining both cycling and the digital experience by integrating sensors and cameras, connecting bikes to the internet and developing an eco-system to create a completely new riding experience. We invested four years into the development. We believe this bike is the turning point for our company, and if I can put my modesty as aside for a moment, will stir up the industry at least a little bit.”

The rider’s smartphone is attached to the handlebar and links to an Android app. Next year, an iOS app will be available. The smartphone collects data based on the bike’s trip and rider, and an array of sensors processes all the information. This data is uploaded to the internet via the bike’s 3G eSIM module with Bluetooth 4.2.

By allowing the bike to play a role in decision-making and automating some of the riding processes, Greyp says the bike can adjust the level of electric assist based on a user’s heart rate. Additionally, if a rider wipes out, the bike can call emergency services.

Riders can also converse with the G6 remotely via the app, and take photos with the built-in cameras or lock the bike down if someone is trying to steal it. The front and back 1080/30p cameras are continuously recording, and over 50 telemetry data sets are being monitored while riding, including bike inclination, g-force, barometric pressure, speed cadence, the rider’s power output, and a rider’s heartrate.

If a rider wants to share their adventure with social media as they ride, the bike’s connectivity allows riders to project real time footage. They can even compete with other G6 riders in a game-like stimulation.

The exterior of the bike consists of a carbon fiber reinforced composite frame and contains an SRAM chain, eight speed derailleur, and front and rear suspension with 5.9 in. of travel, with 27.5 in. wheels wrapped in Schwalbe tires.

The 36 V/700 Wh Li-ion battery pack can be removed for charging. Currently the G6 is available in three variations and runs from $7,380 to $8,500.
