Electric bike provider HumanForest is allowing users in the UK capital London to earn 'TreeCoins', which they can exchange for extra free minutes riding.
HumanForest says the concept is based on the idea that riding one mile on a HumanForest e-bike prevents the same amount of carbon dioxide being released into the atmosphere that one average tree captures in one day.
Cyclists can earn one TreeCoin for every five miles, equating to one minute of extra free riding.
As part of the launch, HumanForest is offering riders 10 free TreeCoins using the code 'TreeCoin' within its app.
HumanForest co-founder Michael Stewart says: “TreeCoins are not just a reward for HumanForest users, they are a form of education. We want every Londoner to know the positive impact they can have on our city."
The TreeCoin idea was realised through a collaboration with European gamification software provider StriveCloud.
StriveCloud co-founder Freek Borghgraef says: "I love how this collaboration helps HumanForest users see their actual positive impact on the environment by using the app."
