In
2013, the company responsible for the 1,088 hp Rimac Concept One all-electric supercar rolled
out an electric vehicle of the two-wheeled variety in the form of the Greyp G12.
At Salon Privé 2015 earlier this month, Croatia-based Greyp Bikes premiered
its successor, the Greyp G12S, which retains many of the innovative features of
the G12, but boasts a more powerful battery pack, new suspension and revised geometry.

The G12S features
a very similar look to the first model, but a keen eye will spot the bulkier shock
absorber in the rear or the single disc brake in place of the twin setup of the
G12. Greyp points out that there are a lot more changes under the hood though, as some
improvements are meant to be experienced rather than seen.

For
starters, the 19-inch frame has been completely redesigned. Once again made
from 25CrMo4 steel alloy tubes, it required a new geometry to accommodate changes
in the electrical components that are hidden behind the carbon fiber panels.
Instead of the two battery modules in the G12, the G12S hosts
only one unit that packs more power for less weight. As it is now positioned
lower in the frame, it helps bring the center of gravity closer to the
ground.

The 84 V battery
has a nominal capacity of 1.5 kWh (up from the 64 V, 1.3 kWh unit of the G12) and can be
fully recharged in 80 minutes from a typical household outlet. Designed and
manufactured in-house by Rimac Automobili using Sony Lithium Ion cells, the
battery pack is controlled by a new bespoke management system and promises a
minimum lifespan of 1,000 charge cycles.

This power
pack feeds an electric motor installed in the rear wheel hub. With the three
riding modes setup carried over from the G12, the motor produces a peak power
of 12 kW in Power mode, down to 250 W in Street mode. The bike boasts a range of up to 120 km (74.5 miles), but the rider
can add some extra muscle power to the mix by pedaling.

A nice
trick up the G12S’ sleeve is the regenerative braking which, according to
Greyp, renders the brakes almost redundant in most cases, while the motor recharges the battery with up to 2 kW of power. Should the situation
require emergency braking, the G12S is equipped with radially-mounted Shimano
four-piston hydraulic calipers on both wheels.

With an electronically limited
top speed of 70 km/h (43.5 mph) in Power mode, this extra stopping power will
probably come in handy sooner or later. In Street mode the G12S is limited to a
25 km/h (15.5 mph) maximum speed, corresponding to the limit that distinguishes
electric bicycles from electric motorcycles in the eyes of European Union law.

Like its predecessor, the 48.5-kg (106.9-lb) G12S is meant for both on- and off-road riding and Greyp has made
sure it will be up to the task by kitting the bike out with brand new adjustable Rockshox
suspensions. These include a Vivid R2C rear shock and Boxxer RC forks that now
feature 200 mm (7.9 inch) of travel, compared to the 180 mm (7.1 inch) of the
G12.

One of the most noticeable
features of the G12S is the 4.3-inch color touchscreen display with an
integrated finger scanner. In similar fashion to the previous model, it can
be programmed for multiple users’ thumbprints, but also allows different fingers of
the same person to be assigned to different riding modes.

Greyp is
already accepting orders for the G12S, with prices starting at €8,330
(US$9,400). An on-line configurator guides the customer through the process of personalizing their ride with several preset color options available, complemented by a custom
palette for complete freedom in combining colors for the side panels, rear
suspension spring and wheel decals. For a little extra cash, the G12S can be factory-equipped
with Maxxis Hookworm 2.5 x 26 inch off-road tires and mudguards.
