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

Santa brought the Rumbler

The wife was thrilled and didn’t understand why there was a helmet under the tree until she opened the garage door. Haven’t had a chance to go for a ride but reviewing the Rumbler knowing it a solid ride, the specs list speak for themselves

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!
