Electric bike "MIG" from a team of enthusiasts from the University of Mechanical Engineering
A team of enthusiasts from the University of Mechanical Engineering (MAMI) in Moscow, as part of the competition, built an electric-powered moped, where it took 1st place in the overall standings and took a separate prize for dynamic tests, since this moped was faster than the serial German apparatus of the company sponsoring the event Elmoto.
In the process of creating the MIG-1 electric bike, students and postgraduates of various specialties and from different courses participated.
It was necessary to first decide on the concept of the future bike, conduct market research, and then design a 3D model in the Avtodesk Inventor of all nodes.
Only then did the drawings of the parts go to manufacture and purchased bicycle components, at the same time economists actively joined the work of engineers, calculating the cost of starting a series of mopeds in the first 3 years, and in parallel with this they did the calculation of the cost of the moped on the fact of creation.
As parts made according to the drawings and bought in the store appeared, the assembly process took place. A frame made of sheet steel was cooked and a pendulum made of steel pipes, the electrician collected all the electronics, the carbon kit was also glued independently under vacuum, according to pre-skinned master models.
Some technical specifications:
Tires:
Front Odyssey Path P-Lyte 24×2.1"
Odyssey Aitken P-Lyte 24×2.25
As an electric drive used rear motor-wheel Elmoto HR-2 1.7 kW (max.2 kW) and with 50 Nm of torque.
83% efficiency.
Mini-E external controller.
Battery Elmoto Lithium-Ion 48v 31.5Ah
Charger 4A (standard charger) – 4 hours to 80% capacity, 6 hours to fully charge.
Fast charger – 2 hours to 80% capacity, 4 hours to fully charge.
Maximum speed of 80 km/h
Acceleration from 0 to 42 km/h in 5 seconds
Average mileage on one charge 65 km
The weight of the device is 47 kg
Average power consumption 18Wh/km
The mileage since its creation (2013) was 1450 km.
The cost of an electric bike is 140 000 rubles.
