UNY is committed to supporting the development of green technology. One of the results was the UNY Inobike bike. To ensure Inobike reliability in actual use, on January 7, 2021, the Faculty of Engineering UNY, held a mass trial which 100 participants attended. This activity is carried out on a limited basis while still referring to the Covid-19 prevention protocol. "We will use Inobike to support a green campus in order to reduce carbon gas emissions so that air quality on campus is improved more," said UNY Vice Chancellor for Student Affairs and Alumni, Prof. Dr. Lantip Diat Prasojo, M.Pd.
Inobike UNY is the work of lecturers and students majoring in Mechanical Engineering UNY. This bike has lighter weight than ordinary bicycles. In the development process, the students have made 143 bicycles with 13 electric bicycles and the rest manual bicycles with standard and premium types. All the processes of making these bicycles are carried out by students under the guidance of Mechanical Engineering lecturers starting from frame design, casting, welding, cutting to the painting process. Inobike UNY results from UNY's collaboration with C Maxi Alloy cast and ED Aluminum.
Dr. Apri Nuryanto, M.T., Head of the Department of Mechanical Engineering Education of UNY, explained that the electric type Inobike could go up to 40 kilometers (km) on a single charge with a charge of approximately 2 hours. INOBIKE UNY bicycle is an early example of research that is integrated with learning and community service. "This work is a manifestation of triple helix collaboration, namely UNY as a provider of research concept and human resources, industry partner as business actors that generate innovation, and Government as a regulator," said Apri.
Inobike UNY has a pedal-assist feature which, when pedaled, the bicycle will move faster. The driving dynamo uses Hi-Speed BLDC 36V 350 W and a 36V 6.4Ah 230Wh Lithium-Ion Battery. The battery-driven engine automatically starts working to push the bike faster, helping cyclists not to tire quickly. "However, the pedal-assist system can work well for sloping road tracks, not climbs," explained Apri.
"On the bicycle handlebar, there is an LCD to adjust the speed with five-speed levels," added Apri.
Inobike UNY is still used internally on campus. However, this bike will be available on the market soon. Regarding the price, Apri said there are several classes. The standard type will be around Rp. 4 million, the premium type is Rp. 5 million, and the electric bicycle type is around Rp. 10 million. "What distinguishes each type, of course, is the material and specifications, and currently, we are in the process of making manual books of each type for the future market," said Apri. (hryo, Tj.Lak)
