I pre-ordered the Rumble a while back and picked it up today. Amy was always very helpful in answering all my questions. I never felt any pressure at all. She wanted to make sure I got just the bike I wanted. Thank you, Amy

Thank you so much for your kind words and for choosing the Rumble Step-Through E-Bike. We're thrilled to hear that Amy was able to provide you with exceptional service and help you find the perfect bike. We appreciate your support and hope you enjoy your new ride! Happy cycling!

Nice Bike For The Cost

I bought my 4th Cyrusher recently. All 4 have functioned well and were reasonably priced. If they had a loyalty program I'm sure I would have qualified. I purchased 3 online directly from Cyrusher and one from Ego Depot's Bike shop in Clemont already assembled. Turns out they are easy to assemble and didn't need to spend the extra for an assembled bike!

Hi there! Thank you so much for leaving us a review. We're thrilled to hear that you've had a great experience with our Rumble Step-Through Ebike. We appreciate your loyalty and are happy to hear that you've purchased multiple bikes from us.Thank you for choosing Cyrusher and we hope you continue to enjoy your bike! Happy riding!

My first e-bike experience

I’m retired, live in a hilly community, which until now has prevented me from enjoying bicycling. No more! The e-bike was the answer I’ve been looking for. My Cyrusher experience has been great from start to finish. I love my new bike.

We're so happy to hear that the Rumble Step-Through Ebike has been the perfect solution for your hilly community! Thank you for choosing Cyrusher and for taking the time to leave us a review. We're thrilled to know that your experience with us has been great from start to finish. Enjoy your new bike and happy riding!
