In2013, the company responsible for the 1,088 hp Rimac Concept One all-electric supercar rolledout 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 premieredits successor, the Greyp G12S, which retains many of the innovative features ofthe G12, but boasts a more powerful battery pack, new suspension and revised geometry.

The G12S featuresa very similar look to the first model, but a keen eye will spot the bulkier shockabsorber in the rear or the single disc brake in place of the twin setup of theG12. Greyp points out that there are a lot more changes under the hood though, as someimprovements are meant to be experienced rather than seen.

Forstarters, the 19-inch frame has been completely redesigned. Once again madefrom 25CrMo4 steel alloy tubes, it required a new geometry to accommodate changesin the electrical components that are hidden behind the carbon fiber panels.Instead of the two battery modules in the G12, the G12S hostsonly one unit that packs more power for less weight. As it is now positionedlower in the frame, it helps bring the center of gravity closer to theground.

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

This powerpack feeds an electric motor installed in the rear wheel hub. With the threeriding modes setup carried over from the G12, the motor produces a peak powerof 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 ridercan add some extra muscle power to the mix by pedaling.

A nicetrick up the G12S’ sleeve is the regenerative braking which, according toGreyp, renders the brakes almost redundant in most cases, while the motor recharges the battery with up to 2 kW of power. Should the situationrequire emergency braking, the G12S is equipped with radially-mounted Shimanofour-piston hydraulic calipers on both wheels.

With an electronically limitedtop speed of 70 km/h (43.5 mph) in Power mode, this extra stopping power willprobably come in handy sooner or later. In Street mode the G12S is limited to a25 km/h (15.5 mph) maximum speed, corresponding to the limit that distinguisheselectric 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 madesure it will be up to the task by kitting the bike out with brand new adjustable Rockshoxsuspensions. These include a Vivid R2C rear shock and Boxxer RC forks that nowfeature 200 mm (7.9 inch) of travel, compared to the 180 mm (7.1 inch) of theG12.

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

Greyp isalready 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 custompalette for complete freedom in combining colors for the side panels, rearsuspension spring and wheel decals. For a little extra cash, the G12S can be factory-equippedwith Maxxis Hookworm 2.5 x 26 inch off-road tires and mudguards.

I rode it at the Long Beach, CA Formula E race and I can't remember ever getting a kick in the pants from an e-bike ever, and I cover EVs. This is THE ideal bike. Efficient, perfect city street carver, and a monster on an accelerator, perfect to get you out of harm's way in seconds. Simply as amazing as it bigger sibling, the Concept one.

I have the g12 here in the UK and I absolutely love it. It gets used every day for everything. Work, shopping, socialising. Everyday after work I put her on charge for an hour while I get changed and have lunch and then put my head phones in and off i go on my afternoon ride. Somewhere different each and everyday. The greyp is like nothing else you have ever ridden, yes you could buy a " real bike or a car for that money " but no real bikes or cars have ever given me the same smile on my face the way this does. Until you've ridden one or owned one you won't understand. I have also had a go on the g12s and that is also amazing and wish I had the money to have one of each. The company them selfs are extremely helpful when ever you have any questions about the bike and make you feel like your part of the Rimac family. A true peice of engineering excellence.

I don't like the yellow plastic shell stuff. Unless it's super tough, it's going to go bad pretty quickly. The least they could do is show us what's inside. As it is now, it's a wind-catching sail for crosswinds. Back to the CAD bay.
