Making a bicycle that weighs only six to seven kilograms is not the easiest task in the world.Now, imagine a bicycle that, in addition to weighing 6.872 kg, has an electric assist pedal system!That's the case with Freicycle, developed by Dr. Dennis Freiburg, a German mechanical engineer.

A former employee of the Mechanical Processing Institute (ISF) at the Polytechnic University of Dortmund has officially received a world record certificate for the world's lightest electric bicycle.The title, officially confirmed by GUINNESS WORLD RECORDS, is "The lightest electric bike prototype".

Freicycle is built around ultralights made with carbon fiber frames by German high-end bike maker Merida and supplied by Freiburg.

Anyone who thinks the power savings in Freicycle prototypes are just for weight loss is wrong.The power of the drive can exceed the specified 250 watts significantly and is limited only for legal reasons.Of course, the battery is smaller than a traditional electric bike, but here the Guinness World Records has a set of specifications.

The motor is actually used for remote control of the model helicopter and is attached to the frame by a special bracket.The motor's software is limited to the power (250 watts) prescribed by EU law and to a maximum speed of 25 km/h (15.5 MPH).However, when unlocked, it can provide cyclists with up to 600 watts of power and speeds of up to 48 km/h (30 MPH).

The motor transmits power to the rear wheel housing via the roller.In addition, Freicycle is equipped with lightweight sensors on the rear wheels that transmit speed data to electronic controls on the wheels.Pure has just launched another electric scooter, the company's cheapest yet

The internal handling allows Freiburg to place the control electronics and 137WH batteries in lightweight off-the-shelf beverage bottles.Engineers create new LIDS for bottles and other components (for example, bottle holders) in the 3D printer.Depending on the level of support, the range may be 19-35 km (12-22 miles).For longer ranges, you can easily install additional batteries.

In addition, the bikes also bet on high-end components such as the SRAM Red gearbox and dura-ACE horseshoe brakes.The entire propulsion system weighs only 2kg.
