If you want a stunningly fast, eye-catching electric supercar, you could do worse than the Rimac Concept One. Should you not have approximately US$1 million to spend on one, however, there's still something you can buy that's made by Croatia's Rimac Automobili – the €6,000 (US$8,000) Greyp G-12 electric bicycle/motorcycle/moped-type thing.
The 49-kg (108-lb) G-12 is the more teched-up descendant of the Greyborg, an electric off-road bike that was made and distributed by Rimac mechanical engineer Zvonimir Sučić in his spare time.
Riders can choose to pedal with no assistance, pedal with assistance from the electric motor, or go with motor-power only. When using the motor, users can choose between three driving modes: Street, in which its top speed is limited to 25 km/h (15.5 mph) so it won't be legally classified as a motorcycle; Eco, which maximizes energy-efficiency; and Power, which allows for faster acceleration and a top speed of 65 km/h (40 mph).
According to Rimac, one charge of the 64-volt 1.3-kWh lithium iron phosphate battery should be good for a motor-power-only range of up to 120 km (74.5 miles). Recharging takes 80 minutes, from a standard outlet.
One of the G-12's more interesting features is its 5-inch tablet-like touchscreen user interface. This is what allows riders to switch between modes, plus it displays data such as speed, power output, battery life and estimated range based on current power usage. That display also incorporates a fingerprint scanner, that can identify up to 50 different users, and up to five fingers on each user. This gives riders the option of switching between modes, or accessing other functions, simply by pressing different fingers against the scanner.
Other features include a high-tensile steel frame with a carbon fiber body, regenerative braking, a two-speed planetary Schlump bottom bracket transmission, along with front and rear shocks offering 180 and 110 mm of travel, respectively.
