Great bikes and great service

We've had our bikes for about a month now, and they've been absolutely perfect! When we had some questions about shipping, the customer support team was incredibly helpful and resolved everything quickly. We're really impressed with both the product quality and the excellent service. Thank you!

Honeydew Green

Highly recommend Kingbull

This is my second Kingbull bike. The first was a Discover that I bought as a gift for my adult son, and now I got this Trekker for myself. we both find these bikes absolutely perfect for our needs. ⭐️⭐️⭐️⭐️⭐️ The customer service is outstanding - when I had an issue with my charger, they handled it quickly and professionally.

I absolutely love ❤️ my Trekker...

I've been wanting an E-bike for a while now since I don't have great transportation options. And wow, the freedom this bike has given me is just incredible! Plus I'm super lucky to live near rail trails that can take me all over the place.

Thank you so much for your wonderful review! We're thrilled to hear that you're loving your Trekker E-bike and that it has given you the freedom to explore new places. We're also happy to hear that you have access to rail trails near you - what a great way to take advantage of your new bike! Happy riding! 😊
