There are two schools of thought when it comes to the design of electric vehicles. On the one hand, there are people who think that in order to gain mainstream acceptance, the vehicles should look as normal as possible. On the other, some people believe that such innovative technology should be reflected with unconventional looks. Falling firmly in the latter category are ETT Industries' new Raker electric scooter and Trayser e-bike.
Both bikes feature a laser-cut monocoque aluminum frame, which won each of them an IF Design Award. Additionally, it's possible for owners to 3D print some of the individual plastic components (should they need replacing), such as rear mudguards.
Powered by a 25-Ah lithium-ion battery pack, the Raker's brushless 2,000W motor can take it up to a top speed of 28 mph (45 km/h). One 5-hour charge from a standard outlet should be good for a range of about 50 miles (80 km) of urban use.
Other features include front and rear suspension (120 and 27 mm, respectively), 12 x 3-inch wheels, a full lighting kit, and a total weight of 75 kg (165 lb). It's available for pre-order in a choice of four colors, priced at £2,700 (about US$3,855).
For riders who prefer to do some pedalling, the Trayser's 250W rear hub motor takes it to an assisted top speed of 15.5 mph (25 km/h). Depending on the amount of rider input, the bike's 42V/20-Ah lithium-ion battery pack should be good for a range of up to 60 miles (97 km) – as with the Raker, a full recharge takes five hours.
Other features include a belt drive and Tektro disc brakes, but no suspension. It tips the scales at 27 kg (60 lb), comes in four colors, and can be pre-ordered for £1,700 (US$2,428).
Both bikes can be seen in action, in the video below.

You guys covered it in 2014 here: http://www.gizmag.com/yamaha-electric-bikes-release-2015/31983/
Perhaps 25 amp-hour... That would indicate a 25ah x 72v = 1.8 kWh battery.
On the other hand, they claim it can be charged in 3 hours with a 1.2kW charger, which would indicate no more than 3 to 4 kWh capacity for the battery. It would take 20+ hours to charge a 25kWh battery with that charger!
Hard to see how they can expect to be taken seriously when the specs/numbers are obviously out of whack...
