We delivered a Sprint 7 to Nottingham University's eco house yesterday.

Located on a hill close to the department for the built environment, it's well placed to catch both the sunshine (for natural light and power) and prevailing winds (to spin the turbines and test the double glazing). The same hilliness means an electric bike will prove useful for getting around the campus.

As a company, we're looking into more ways to make electric cycling an end-to-end energy-efficient, carbon-negative way to travel, so knowing at least one of our bikes is not relying on coal, oil or gas to fill its batteries is satisfying.

We think it's likely that there are many more out there though. Please get in touch if your electric bike runs off the grid.
