Greyp Bikes A bicycle when you want it, a motorcycle when you need it. ABOUT US CONTACT ORDER Play video Overview Features Performance Battery Mechanical Specifications Overview The Greyp G-12 is designed from the ground up to combine the best of both worlds – motorcycles and bicycles. It is a bicycle when you want it, or a motorcycle when you need it. Our electronics and hardware wizards have spent countless hours developing a unique user experience, yet unseen in the e-bike industry. Tooltip Tooltip Tooltip Tooltip Tooltip Tooltip Tooltip Dressed Drag to reveal Drag to reveal Naked Features Fingerprint activated You don’t ever need to worry about keys again. The G-12 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 speed-mode. The owner can limit rights to other users – you can lend your bike to your friend and limit his riding-time and speed. STREET ECO POWER Driving 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 G-12 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 on the touch-screen away when you need it. Be informed 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 to plan your trip. Performance No need to pedal You can pedal if you want, assist the motor or drive the G-12 like a motorcycle. It will reach 65 km/h without any assistance by the rider. You never need to sweat riding up a hill again! Range You can reach up to 120 km of range with a single charge. Our sophisticated range estimation algorithms predict the remaining range based on your riding style and at the same time, show you the maximum range with a conservative driving style from that moment on. This enables you to predict when to slow down in order to have enough range to make it to your destination. Regenerative braking Press and hold ACCELERATE. 21 km/h BRAKE ACCELERATE You will almost never need to use the G-12’s mechanical brakes. The motor can recharge the battery with up to 2 kW of power while braking which is more than enough most of the time. Still, we made no compromise when it comes to brakes – hydraulic dual discs in the front and a single disc in the rear (both with 203 mm diameter) provide enough stopping-power for even the most demanding situations. Battery Charge The G-12 can be re-charged from 0 to 100 percent in only 80 minutes – from a standard 220V outlet. A full charge consumes just about 1,3 kWh of energy which cost less than 25 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, is providing 1,3 kWh of juice for the G-12. 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 watch how each cell is behaving in real-time on your screen. The BMS monitors 5 temperatures within the battery. We have spent years on the development of this system in order to guarantee a long battery-life. Battery-cells The G-12 is equipped with Lithium-Nanophosphate battery-cells manufactured by A123 Systems. These cells are considered as the best high-performance battery-cells currently in existence. Those cells deliver ultra-high power and energy density, while offering superior safety and life. Thanks to the sophisticated Rimac Automobili BMS and A123 battery-cells, we can expect a minimum life of 3000 cycles (charges and discharges) while still maintaining 80% capacity. Mechanical Rugged design We have not only focused on the electric part of the equation. All mechanical components are engineered for demanding use over many years – the G-12 can withstand jumps, down-hill rides and rough surfaces while still maintaining a comfortable ride and seamless 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 stressed-parts are FEM analyzed and stress-tested on benches. Hand-laminated carbon-fibre is used for the body.
