2 years with Zero issues. So much easier having Jupiter in Tampa for sales and service. Easily go 40 miles on a full charge, BUT give the battery time to recharge.

Was in the market for a new e-bike, but didn’t want to spend too much, but wanted to upgrade my original e-bike. After shopping around found numerous positive reviews for the Jupiter Defiant. Also to my surprise they had a sale through Costco which pretty much sealed the deal. After receiving the bike, installation wasn’t too hard. My first ride confirmed any doubts that I had were in accurate. This bike is fun, fast, well built and couldn’t be happier.

My wife and I recently received our Defiant E-Nikes (matching set). Set-up was easy, but the controller user manual were not up to date! Guess we will figure that out as we go. Really enjoy riding the bikes!! Time to look at accessories.
