Iran-Made Eco-Friendly Bicycle Works with Multiple Energies

“This hybrid-electric-gas-mechanical engine with multiple energy management capabilities can be installed on any bicycle and turn it into an electric and automatic bike,” Shahin Mamouriani, one of the researchers, told ANA.

“This bike has a hybrid mode, that is, the cyclist moves, pedals, and when you are on the downhill, you can put the bike in charging and production mode and charge the bike while generating electricity. If you get tired of pedaling, you can put the bike in electric mode,” he added.

Noting that if the bike's battery has run out and the cyclist is tired of pedaling and is not going downhill, he/she can put the bike in ‘Move Hybrid Gas’ mode, Mamouriani added, “In this case, a 100-gram PR gas capsule that is mounted at the back of the bike is automatically turned on and by creating a spark in the housing, it ignites the gas and starts the Stirling engine.”

“This device is able to return nearly 60% of the energy and its Stirling cycle efficiency is about 28%,” he said.

In a relevant development in September, a knowledge-based company founded by graduates of Sharif University of Technology had also managed to produce electric bicycles which are presented to the market at a price much less than the price of foreign samples.

“In our company, we succeeded in designing and manufacturing electric bicycles, and the cost of these electric bicycles is much lower than the foreign models,” Rahim Qor’ani, one of the founders of the knowledge-based company and a graduate of Sharif University of Technology, told ANA.

He added that the electric bicycles, designed and mass-produced by the graduates of Sharif University of Technology, are fully home-made.

“These bicycles are able to move on the steep slopes of Tehran and enjoy the capability to pave a distance of 40 kilometers at a speed of 35 to 55 kilometers per hour with a charge of 3 to 5 hours (depending on the model),” Qor’ani said.
