First off let me give a shout out to Matt, Will, and all the people at Jupiter bikes. They are very professional friendly and go out of their way for customer satisfaction. That being said the Defiant is a nice bike right out of the box. I had no problems at all putting it together and getting on the road. I ride it daily and have put 2500 miles on it. I live in the city and ride the bike lanes with a lot of traffic around me, so I have made few changes to the bike for safety and comfort. 1st was a suspension seat post and front forks then mirrors a rear rack with saddle bags and rear brake light with blinkers, and most important a pair of Juin Tech MTB system hybrid hydraulic brakes. This bike now stops on a dime. I am now on my second pair of tires ( they lasted me about 2000 miles) and my 3rd battery. I love this bike and hope to keep it for many more miles. When I bought this bike the Defiant Pro was not available, or I would have purchased it. However I have no regrets with my purchase of the Defiant it is so fun to ride. I hope this helps.

We have had our two Defiant bikes now for about a year. We have been on all kinds of different terrain and trails. These bikes are awesome! They have handled everything we have tried so far and we love them. The fat tires give some shock absorption and handle sand, lose gravel well. We are in the process of upgrading our bikes with front suspension and can’t wait to try them out with the front shocks. I am a little heavier than my wife so my battery doesn’t last quite as long as hers but we can get 40 plus miles on one charge. We ride hilly trails and have a blast just riding together enjoying our time. These are by far the best bikes you can buy and we are so happy we purchased Jupiter! The service has been outstanding also. I want to especially thank Mathew Russell for the customer support he has given us with purchasing the upgraded front forks. Thanks Jupiter for making such a great bike.
