The Greyp G12S is a 2nd generation of our first electric bicycle - the Greyp G12. The G12 was designed from the ground up to combine the best of both worlds – motorcycles and bicycles.

Its successor, the Greyp G12S takes the whole experience even further. Our electronics and hardware wizards have spent countless hours developing a unique user experience, so far unseen in the e-bike industry.

Fingerprint activated

You don’t need to worry about keys ever again. The biometric sensor ensures that you are the only one to unlock the bike with a mere finger scan. Your thumb can lead you the Street Mode, while your middle-finger will activate the Power-mode.

Riding modes

Most EU countries consider two-wheeled electric vehicles as motorcycles if they can reach a speed in excess of 25 km/h and have more than 250 W of power. The G12S has a special mode to comply with the regulations for road vehicles – which limits the speed and power. Still, the top-speed is just a tap away on the touch-screen when you need it.

Be informed

The Greyp G12S user interface provides information on speed, consumption, ideal and calculated range, temperatures and much more. Sophisticated electronics collect processes and display a large variety of data to the rider, which helps you plan your rides more efficiently and keeps you up to date with all of the bike’s parameters.


No need to pedal

You can pedal if you want, assist the motor or ride the G12S like a motorcycle. It will reach 70 km/h without any assistance from the rider. You can forget about sweating ever again while riding up a hill!


The Greyp G12S can reach up to 120 km of range with a single charge.  Sophisticated algorithms predict the remaining range based on your riding style and by that, make it possible for you to predict when to slow down in order to preserve energy and substantially to reach your destination.

Regenerative braking

Brake Accelerate

You will almost never need to use the mechanical brakes. The motor can recharge the battery with up to 2 kW of power while braking which for most of the time is more than enough.

Nevertheless we didn’t compromise on the brakes either– one of the best hydraulic disc brakes on the market today provide for more than enough stopping-power even for the most demanding situations.



The G12S can be re-charged from 0 to 100 percent in only 80 minutes – from a standard 110V/220V outlet. A full charge consumes just about 1, 5 kWh of energy which cost around 30 euro-cent in Europe (according to average electric energy cost in the EU).

Battery pack

A state-of-the art battery pack, designed and manufactured by Rimac Automobili provides for 1,5 kWh of juice for the G12S.

The bespoke BMS system keeps an eye on each cell and checks the voltage 100 times per second. Advanced algorithms calculate the remaining State of Charge, range, and many other factors.

You can even observe how each cell is behaving in real-time on your screen. The BMS monitors 5 temperatures within the battery. We have spent years on developing this system in order to guarantee a long battery life.

Battery cells

The G12S is equipped with Lithium-Ion battery cells. (These cells have high energy to weight ratio). With the new battery pack, we managed to increase the battery capacity and lower the weight of the bike.

Thanks to the sophisticated Rimac Automobili BMS and Lithium-Ion battery cells, we can expect a minimum life of 1000 cycles (charges and discharges) while still maintaining a 75% capacity.


Rugged design

Our focus wasn’t only on the electric part of the equation. All mechanical components are engineered for demanding use over many years – the G12S can withstand jumps, downhill rides and rough surfaces while still maintaining a comfortable ride and flawless function of all components.

Chassis & Suspension

The chassis and rear swingarm are made out of high-grade, high-tensile 25CrMo4 steel. The tubes are CNC bent and cut while the sheet-metal parts are CNC laser-cut. All parts are welded on a custom-made jig in order to assure quality and tight tolerances. All the stressed-parts are FEM analyzed and stress-tested on benches. Pre-impregnated carbon-fiber is used for the side covers.
