2022 Photo Contest

Nov 10 2022

Dear ASTRO backers,

Considering the difficulty and inconvenience of making videos, we have changed the video contest to photo contest. PLUS, we’ve UPGRADED the prizes!


The photo contest requirement:

Take and upload at least three photos to participate.

The photo can be taken with any device and shared on Facebook, Instagram, Pinterest, and Twitter with the following tags: Twitter @C3Strom, Facebook @c3strom, Instagram @c3strom, Pinterest @c3strom

We strongly advise you to do lifestyle shots – a creative session that shows you riding your bike, having fun while riding, and exploring the nooks and crannies of your area with the Astro, or another riding style you want.

Each participant will receive a $50 coupon on our website: https://www.c3strom.com/


We will choose the top 15 photos and then hold a poll on Facebook on November 25th, 2022, with the winning photos selected by votes on December 5th, 2022.


The Upgraded Prizes:

1st place – $500 cash *1 →  $800 cash *1

2nd place – Mid-basket for ASTRO*3 → ASTRO Battery *2
