5. BMW Cruise Electric Bicycle

BMW says that the 20kg (44lb) bike with pedal assist is capable of 25kmh and a maximum range of 85km. It uses a 250W motor produced by Bosch and the bike’s lithium ion battery is mounted on the down tube. The electric motor is placed under the bottom bracket. The Cruise bike has disc brakes and four modes of assistance, ranging from Eco to Turbo. A detachable computer will show speed, battery life and other parameters.

4. Campagna T-Rex 16STM

As much as we wish we were talking about the 3.0L twin-turbo, we’re not. We’re actually talking about a 1.6L six cylinder BMW engine that produces 160 hp and 129 lb-ft of torque; enough to send this tiny three wheeler to 60mph in under five seconds. The T-Rex is certainly not just a straight line machine, at only 1,100 lbs it should handle quite nicely, and the integrated roll cage should keep occupants out of harm’s way should things go awry.

3. Smartphone Breathalyzer

Next time you go out on the town to have some drinks, don’t leave home without the Breathometer. This pocket sized breathalyzer plugs right into the headphone jack of your iPhone allowing you to measure your blood alcohol level any time, any place. Simply blow into the device, and let the Breathometer work its magic.

2. 3D-Printed Snowboard

The Seabreacher X is the latest and most advanced submersible watercraft that we have built to date: This exciting new version is based on the dolphin-inspired Seabreacher J, but it has a more aggressive Shark-style body. The X model also steps up the performance envelope with a 260hp supercharged engine, propelling the vessel to a top speed of 50mph on the surface and 25mph below.
