Recently, we brought to you six of the most advanced electric bike designs that dazzle us with their ingenuity and futurism. When it comes to innovation, however, none can beat Croatia-based Rimac Automobili. Maker of the famous 1088-hp Concept One supercar, it has, over the years, forayed into other arenas, particularly the motorized bicycle industry. At Salon Privé 2015 this month, the company launched the Greyp G12S, an updated version of the earlier G12, sporting a set of powerful batteries, new suspension and a spectacular design.
Combining the best features of motorcycles as well as bicycles, the vehicle boasts a range of advanced technologies, aimed at developing a truly unique user experience. Although largely similar to its predecessor in appearance, the G12S has chunkier shock absorber and only one disc brake instead of the former’s twin setup. The redesigned chassis, built using strengthened 25CrMo4 steel tubes, makes room for the various modifications in the bike’s electrical components.
Unlike the G12 which contains two battery sets, the new bicycle possesses a single, and more powerful, 84 V battery unit. With a nominal rated capacity of 1.5kWh (as opposed to the 64 V, 1.3 kWh set of the former), it can be recharged, up to 100-percent, in less than 80 minutes, from a regular 110 V / 220V charging outlet. The battery pack, inside the G12S, is manufactured by the engineers at Rimac Automobili, using lithium-ion cells, and is programmed to constantly monitor the voltage, state of charge, temperature, range and other factors. It can also notify the rider about the system’s health, through real-time data. According to the developers, the battery pack can last for a minimum of 1,000 charge cycles.
The bike offers the option of three riding modes, with different speed limits. For instance, in the Power mode, the electric motor produces maximum power of 12 kW and speed of 70 km/h (around 43.5 mph), which drops to 250 W power and 25 km/h (nearly 15.5 mph) while riding in the Street mode. This conforms with the speed regulations, for two-wheeled electric vehicles, in the European Union. The G12S can run for over 120 km (about 74.5 miles) on a single charge, without any assistance from the rider.
A system of advanced algorithms allows the user to change the bicycle’s speed, according to the amount of energy remaining in the battery. The design features regenerative braking, during which the motor recharges the battery with power of over 2 kW. For the purpose of emergency stopping, the G12S is also equipped with powerful hydraulic disc brakes. Weighing around 48.5 kg (or 106.9 lb), the bike is designed for both on-road and off-road riding. It is built such that it can withstand jumps, rough surfaces and slopes, all the while providing a smooth, comfortable ride. The adjustable RockShox suspensions, including a Vivid R2C rear shock and BoXXer RC forks, boast 200 mm of travel.
A 4.3-inch interactive display provides real-time information about the bike’s speed, power consumption, temperature, calculated range and so on. Furthermore, a biometric sensor allows the rider to lock, and unlock, the bicycle with a simple finger scan. The Greyp G12S is currently being sold for around $9,400 (approx. €8,330). Buyers can choose a set of different colors, for the side panels, suspension springs and wheel decals.
