The 3-radical E-Motorcycle Concept that ever made

Ongoing advances in all-electric drive trains have opened up some radical design possibilities for e-bikes, and while many of the electric motorcycles we've seen stick to a conventional layout, others are definitely looking to push into territory where only highly-customized bikes dare to tread. Maybe you are interested in having one of them ..

Here are three radical designs electric motorcycle ever produced,

3. Agility Saietta
Freed from the constraints of complicated combustion engines and all the associated tackle, designer Lawrence Marazzi has unveiled a brand new, fully electric British motorcycle that turns the rules of motorcycle design on their head. The Saietta features a hossack-inspired front end, an eye-popping fairing design and a crazy degree of mass centralization that could only be achieved with battery cells. Billed as a guerrilla commuter, it promises to be a very exhilarating ride.

It's the Agility Global Saietta, an all-electric sports bike that will come in two flavors: the 50 mile (80.5 km) range Saietta S and the 100 mile (161 km) Saietta R. This bike is capable of accelerating from rest to 60 mph (100kph) in under four seconds, whereas R riders will have to wait another tick of the stopwatch due to extra battery weight.

At this point we don't know much about the bikes themselves beyond what you can see in the photos, which show a trellis frame cradling a sizeable battery pack. The swingarm is a combination of machined parts and pipes, rear suspension elevated to make room for the electric motor sitting just above the pivot point. Front suspension also shows an unconventional design, offset steering linkage and a single damper eschewing the traditional fork design.

Naturally that extra range and speed will cost you: £9,975 for the S and £13,975 for the R, figures that equate to roughly U.S. $16,200 and U.S. $22,650. Hefty sums, both, but nobody said being on the cutting edge of the humpbacked sport bike trend was going to be cheap. This bike has the power to weight ratio of 675 hp per tonne.

2. Lito Sora
Montreal's Lito has thrown a new electric motorcycle that makes some pretty outrageous claims. Motorcycle is equipped by an electric engine that can generate 12 kWh of power which stored in onboard lithium polymer batteries gives the Sora a massive 300 km range – that's 185 miles between charges. What is more impressive of the electric motorcycle can be driven up to a top speed of 200 kph (125 mph) so that it can make you feel like flying.

With chopper/fighter bad boy looks and some interesting and innovative features like in-dash touch screen GPS and electronically adjustable ergonomics, the Sora looks like an absolute animal of a machine. Drop it down for a relaxed, cruisy highway position, crank it up for extra agility and a more aggressive sporting stance. It'll be fascinating to see what sort of difference that system makes to the feel of the bike.

One interesting innovation on the Sora is the way the tank-mounted GPS system is integrated with the battery management system. Punch in your destination, and the Sora will calculate how much power it needs to get you there – and it will adjust your available power along the journey to make sure you get there with charge to spare. It's a very smart feature designed to eliminate the range anxiety you tend to feel on an electric knowing that your battery is dwindling and it'll take anywhere up to several hours to get it charged back up.

The Sora is more than just a concept – Lito has built at least one of these things, and in the flesh it looks, well, which is tough! The bizarre downward slope of the aluminum frame quickly becomes familiar to the eye, the front end is clean and muscular, and the bobbed back end looks absolutely superb. The flared battery cells are an acceptable substitute for a big lump of engine down below, the belt drive and swingarm look techno-amazing and the overall effect is one hell of a sexy bike. There's no price listed for this beauty, but it's going to be expensive.

1. zecOO
Designed by Kota Nezu of Znug Design, the zecOO was unveiled at the 2012 Tokyo Motor Show in March and is reportedly headed for small scale production. the zecOO’s stylistic features like hub-center steering, large-sized wheels, long, raking windshield and single sided swing-arm that immediately grabs the attention of the onlookers. However, the performance specs are not as powerful as the design of this low-rider aesthetic.

The zecOO is a handmade motorcycle, assembled by highly-skilled craftsmen for each customer. Many of the parts are machined from solid aluminum alloy block, and it is made with meticulous attention to detail, even to the individual screws. The characteristic front and rear swing arms is welding the aluminum alloy board deliberately, polished and finished up.

The combination of YASA 750 motor and SEVCON GEN4 controller provide a maximum torque of 750 Nm, and since it is an electric drive, the acceleration is smooth and uninterrupted. With zecOO, riding feeling of a different dimension is born. The zecOO has a range of between 88 and 136 km (55 to 85 miles), which is pretty good. Top speed is 120 kph (75 mph), which is comfortably more than the 100 kph limit on Japanese highways. Weight is a hefty 245kg, but on the plus side, the bike takes just four to six hours to charge.

And, the price too stands out; the electric motorbike zecOO is expected to cost around 6 million Yen (U.S. $70,000), and the company will reportedly head for limited edition production run. *** [EKA | FROM VARIOUS SOURCES | AGILITY | LITO GREEN MOTION | ZNUG DESIGN | ZECOO MOTORS | GIZMAG | BIKEEXIF | GREEN LIGHT NATIONAL]
