  3500 miles on her and just about as many smiles

By mooseknuckle51 on June 27, 2022

Six months ago I left this review on Google maps. I can't say enough good about this company and the commitment to quality of product, service and consumer relations. Customer Service has been excellent in answering my questions or concerns usually within a couple hours of email if not the same day... I highly recommend this company and their products... proud owner of a JupiterBike Defiant. Almost 1200 miles on it and looking forward to many more. I now have over 3500 miles on my Defiant and have had a wonderful experience with the Tech Dept. and Customer Relations when any concerns have popped up they have done a good job at addressing my concerns and getting me rolling again.

I bought the Discovery X5 (2 of them) for the boat and they do everything we expected. The Discovery X7 is perfect for the RV too. But the Defiant is the preferred choice for my sons (they are in their 30s). Love the support/service as we travel - any bike shop can repair or fine-tune any issues we've experienced.

  Awesome Bike, Awesome Service, Great RV Bike!!

By tbridges201248 on May 10, 2022

Received my JupiterBike Defiant in 3 days! Bike is all and more of what I had searched for and more! Built like a tank! Customer Service 100% Happy Camper! Thank you Rob!! The E-Bike is way too fast for me, but may have the need for speed to keep up with the kids. Lol. Btw, speed control is adjustable for your safety. I am 345 lbs. Pulls me just fine. Just need a wider seat for bigger chops. Lol The actual seat that comes with it is fantastic for small butted people. I'm 5'5" and the center bar is just perfect to get on or off the bike. Just ordered the cool rear cargo rack to go with it. Oh btw, order the safety chain lock, its awesome! It rides great, but I don't intend to be in a bumpy yard or riding rough trails. So the smoothness of the ride will be fantastic in RV parks and trails. Did many nights and days of research to find the perfect E-Bike for the money and product reviews. This is it"...The Jupiter Defiant". Seriously, thinking 🤔 about buying another Defiant E-Bike for my roommate next week. Kind-a waiting on a discount to come about on the second one. Just hoping 🙏 Very Satisfied Customer!! Thank you for your customer service! Ask for Rob! He's "the man"!!! JupiterBike Company Location: Tampa, FL USA

  More than expected!

By fladgelator on March 16, 2022

After many hours of research, the defiant seemed to be the best option of price, features, and very important....the weight! I have mobility issues that make walking any distance(let alone lifting anything) quite difficult. My Defiant gave me a part of my life I sorely missed. Could barely hold back the tears on my test ride. Its totally bad ass! My black beauty is very sexy and really moves in the sand, gravel, dirt, grass, and on the hardtop! I had the opportunity to visit Jupiter in Tampa while I winterd in Florida. The customer service was awsome! MEGAN IS THE BOMB! She was so helpful! She got all the paperwork together and had it put together for me too!!! Nothing but good things to say! The seat is nice!! I also got the upgraded seat post! Anyway I could go on about the great battery life, great shifter, easy read screen, assist levels, and everything else, but you'll find out when you get yours!
