If you know of Rimac Automobili, it’s probably for being the maker of the Concept One electric supercar, but the Croatian car company is also the maker of the little known Greyp G12, a high performance electric bike. Performance comes at a price, the G12 starts at 6,500 EUR ($7,200 US), but the bike is equipped with a 1.3 kWh and a battery management system (BMS) based on the knowledge acquired during the conception of Rimac’s $1 million electric supercar.
There are 3 use-cases for the Greyp G12: pedal only, pedal-assist and throttle only. There’s no need to switch mode between the roles of the pedals. If you want to only pedal, you use the pedals and if you want the electric motor to assist your pedaling, you use the throttle while pedaling, and finally you can stop pedaling and only use the throttle.
For the throttle itself, there are 2 modes: Street Mode and Power Mode. On the Power mode, the Greyp can reach a top speed of 44 mph (70 kmh) with street tires on flat surfaces and it can achieve a range of 75 miles (120 km).
The bike also has some luxury features justifying its ticket price, like fingerprint activation:
The G12 can save up to 50 users, and every user can save up to 5 fingers. You can choose that a certain finger starts the bike in a certain mode. Your thumb can lead you the Street Mode, while your middle-finger will activate the Power-mode.
The bike is equipped with mechanical brakes, but Greyp says you will barely use them because the motor allows for regenerative braking with up to 2 kW of power being sent back to the battery.
You can watch Greyp bikes invading the streets of Monaco in this video and read the full specs of the bike below:
