    My E-bike,...Heybike!!!

    My Heybike is awsome ! it runs smooth and I feel safe with its very effective disk brakes system. Also, I feel like I got a good deal compared to the quality of my bike. This is my second e-bike. The previous one was made in Australia (Betanya) Pika, and it was very difficult to get parts. So, I ended up getting rid of it. Now, with the support of Bestbuy corporation, I will be able to get parts and recommendations.
