Summer Bike Challenge 2021

Saddle up for the Summer Bike Challenge!

Follow us on social media and participate in our monthly challenges, complete activities and get comfortable replacing car rides with rides on your bike.

All commuters who log at least three bike trips during the month of June win a 20% off code they can use for GruneStrasse products, and one lucky winner gets the GruneStrasse backpack of their choice (up to $200 value). Participate by signing up and logging your commutes, trips and rides on
