I ride my defiant everywhere. I take it hunting and to the beach. It easily folds up and fits in the back of my jeep. Solid built bike!

   Jupiter Customer Service

By jmbo92 on February 13, 2023

A huge shout out to Josh and Hailey at Jupiter Bikes for helping me throughout the buying process and getting my bikes shipped out quick! I was turned off by Alpha E Bikes after placing my order with them at Javits and not receiving any follow up or answering my e-mails and calls about my order. Deal direct with Jupiter, they won't let you down! And they shipped out NEXT DAY! Josh listened to my concerns about Alpha and did the right thing in getting me my bikes! Would absolutely reccomend JUPTERBIKE.COM.

   Defiant Review

By tbip on July 14, 2022

After a little over a year my review of the Defiant... I have spent more time on my bike that I ever have, it brought the fun back to biking. With a few very minor tweaks it became even more solid: - Kinect Seat-Post for an even smoother ride - Snow Air Fork - Brooks Seat You can go a pretty good distance on level 1, approximately 30 to 40 miles depending on the terrain. Overall, I highly recommend this VERY SOLID bike and I would definitely buy again. Pound for pound a bargain.
