Amazing!

Love the size of this bike! I sold my other electric bike which was more of a mountain bike style and love this so much better. I feel safer, it is lower to the ground allowing me to plant both feet on the ground while sitting on the bike. Both my husband I each have one and we love them.

Thank you for taking the time to leave a review! We are thrilled to hear that you are loving your Rumble Step-Through Ebike. We designed it with safety and comfort in mind, and we're glad to hear that you feel more secure with the lower frame. We hope you and your husband enjoy many more rides together on your new bikes. Happy biking!

Love my Rumble

The bike turned up in one box with a full set of tools and an assembly guide. It was easy to put together other than the riser valve screws were very tight - think they were machined in place so perhaps look at not tightening them too much please. Instructions for the LCD readout screen are easy to understand and the extra large tyres are great for crossing rougher ground. Real pleasure to ride and highly recommended, especially for older folk like me who need help to get up hills!

Thank you for such an amazing review. We are so glad you're having a blast with your bike! Happy riding!

So far, so good.

I ride hard. I have owned this bike for 2 weeks. So far, so good. Time will tell. But I liked the first bike, so I bought another. Now I have two. I like having an extra a battery for me, and an extra bike for my friends. At 62 and retired, I feel like a kid again. I already have 200 miles on the first bike.
