Resistance Unit

Resistance Unit is a micro-power generation system that links up with almost any road bicycle. Resistance Unit harnesses the energy produced by you (when pedaling) to generate 12V DC or 240V AC electricity to power a range of appliances such as a laptop, mobile phone charger or a stereo.

Resistance Unit includes

  • 1 x 100W Bicycle Generator
  • 1 x Power Pack
  • 1 x Power Cable

What can I use it for?

  • POWER GENERATOR – It can power lights, laptops, and charge mobile phones in off grid areas or where power grids may be unreliable.
  • EDUCATION – As real-time power generation system, when you stop pedaling so does the power, which is invaluable for illustrative and educational purposes. Resistance Unit is fun and participatory energy education tool and combines many aspects of the curriculum such as PE, Citizenship, Geography and Science. The Resistance Unit is a great introduction to micro-power generation and renewable technologies.
  • BATTERY CHARGING – The Resistance Unit can be connected to a 12V battery to store the power you produce to use later.
  • ADDITION TO SOLAR PANELS The Resistance Unit can be attached to 12V solar panels (up to 180W) to provide power if the weather???s nice.
  • CAMPAIGNING It is an ideal tool for campaigning and in the promotion of renewable energy sources, micro-power generation and sustainable living.
  • HEALTH AND FITNESS SYSTEM You can harness the energy you produce when exercising on your bicycle training stand.
  • EMERGENCY POWER BACK UP It can be used as an emergency power generation and for battery charging on land and on boats.
  • ART PROJECTS As a great way to make small art projects sustainable and participatory.

How much power can I make?

The best Tour De France riders can sustain 300 to 500W over longer periods with short peaks in excess of 1000W. How much power cyclist produces is dependent upon ones strength and fitness. With this in mind, the average cyclist can produce around 50W of power over longer periods with short bursts over 100W.
