   Awesome road e-bike!

By belljr10b on March 20, 2023

We needed ebikes to fit in a Cessna 172 for our summer/fall trips to Nantucket and Martha's Vineyard. So we bought 2 Discovery X5 bikes since we needed ebikes that were light weight, foldable, and had a horn with front/rear lighting. This bike checked all those boxes! We fit one bike in the Cessna baggage storage area (fits perfect through the door!) and the other in the rear seat. Range isn't close to 35 miles, more like 18. However that's okay, islands are flat and I need the exercise! I'm sure JupiterBike will sell more of these bikes. When we ride these from the plane on the tarmac we turn a lot of heads! A lot of pilots we talked to were going to get one or two. Hope you sell more! We will keep recommending the bike.

   Studying Folding Electric Bikes By Larry R. on March 21, 2019

By larry_rigg on February 13, 2023

This is an update to my March 21 2019 review. Our two Discovery X5 bikes are now nearly 4 years old, still going strong and look like new! The batteries do not hold their charge quite as long, but not so bad as to require new ones. The brake shoes are still OK and all parts on both bikes are still working perfectly without any breakage whatsoever! I still highly recommend these bikes for those who desire lightweight transportation, ones that take little storage and insist on dependability and good looks!

   Just what we were looking for!!

By vwfamily on August 03, 2022

We (husband and I) purchased two Jupiter DiscoveryX5 electric folding bikes. We wanted something that we could ride around campgrounds plus also fit in the basement of our motorhome. This little jewel was perfect! We just got back from a big airshow in Oshkosh, WI and rode these all over the campground and everywhere we could. Being senior citizens - 67 and 74 - these allowed us to venture out more and not have to rely on the busses to get us to the venue where everything was taking place. I'm now thinking of places I can ride around my home as I don't want to wait until we travel again to enjoy this awesome bike.

   Discovery X5

By jeffglibert225 on July 23, 2022

I had my X5 for three seasons and have put over 1,800 miles on my bike over three summers. Great little bike. Pedal Assist is great on hills and/or against on-coming strong winds. Only maintenance has been a new rear tire inner tube and new plastic petals (bearing wore out on the original plastic petals). Folding option makes it easy to get in my SUV - I bought the carry bag to keep any grease away from my car interior. Highly recommended.

   Update on The Little Engine that Could

By gilstanden on June 25, 2022

Update to my first review. I've been commuting to/from work 15 miles total on a single charge for two weeks now in blistering hot days. I'm 6'2" 265 lbs. The bike has 30% remaining on the battery at the end of the commute home so i guess it could handle even a 20 mile RT commute for my rider size and weight. The Discovery X5 is in my humble opinion by far the best value in e-bikes out there today and is an engineering marvel.

   A great bike!

By michael on June 17, 2022

It's a great bike. It has good battery life, easy to transport (I can fit two in the back seat of my tiny Chevy Spark). It has good speed and feels really stable for such a compact bike. I LOVE my JupiterBike Discovery X5 E-Bike. I've put hundreds of miles on it this summer.

   Can't say enough good things about this bike!

By scott.m.clarke on June 15, 2022

We are full time boat cruisers and these bikes have been invaluable to us. Everywhere we go people stop us to ask where we got them and how we like them. It was virtually impossible to find an electric folding bike and those we did find were too heavy, too expensive or clunky. The JupiterBike Discovery X5 is easy to transport (we can even load them into our inflatable dinghy) and they perform great. We couldn't be happier!

   JupiterBike Discovery X5: The Little Engine That Could

By gilstanden on June 11, 2022

I am 265 lbs. and 6'2" tall. I needed a bike to commute to and/or from work (6.5 miles each way, 13.2 miles round trip) that also could be carried on intermodal (on buses and/or metro-link trains). I also wanted a bike that was well-under $1000 dollars, had a throttle-only mode in addition to pedal-assist (PAS) modes, and rear-suspension. I also needed an e-bike that could handle a few moderate hills without overheating/cutout of the hub motor. This JupiterBike Discovery X5 really exceeded all my expectations with flying colors. I just finished my first test ride on it. I did lap routes around where I live which include some very challenging hills (not exceptionally long hills, but some 12% grade sections of maybe 25 yards or so embedded in longer gentle grades). The temperature today is 86F with real feel 95F and the 350W hub motor on this Jupiter X5 came through with flying colors! It just kept on going like the pink battery bunny on TV with his drum and big feet. Also, the power delivery was consistent, even when the battery was getting down to 10% or less left, there was still power even in the PAS-1 mode, and of course graded upward power in PAS-2 and PAS-3 as one would want and expect, and even a little bit of throttle-only power even up to the last drop in the battery. In summary as far as endurance and range, this little engine that could Jupiter Bike Discovery X5 carried a 265 lbs., 6'2" man 12 miles on a hilly test course loop comprised of uphills, downhills, and flats, but more than 50% of the ride was climbing some type of moderate to steep hill and this bike handled it all. I was very impressed. My work commute doesn't have anywhere near as many tough hills, so I now feel confident the Jupiter Bike Discovery X5 will handle my 13.2 mile work commute easily. The little headlight that comes with the JupiterBike Discovery X5 is quite bright and it's a nice value-add. It also has a little electric horn which is handy if you ride in congested boardwalk areas etc. and is a nice thing to have built-in anyway. The bike was super easy to assemble. Once the packaging protection wrap is removed, it takes less than 5 minutes to have it fully assembled. No tools at all are required other than a pair of scissors to snip the packaging zip ties. The bike is quite lightweight by electric bike standards - only 41 lbs. according to the documents, and it feels light. I can lift it off the ground easily and I don't do any heavy lifting anymore I'm pretty careful about that, but I feel confident hoisting this onto bike racks on a bus if necessary for intermodal travel events. Keep in mind that with the smaller wheels (16") you must pay close attention to the road surface ahead of you at all times, because with smaller wheels even small potholes in the road can swallow up 16" wheels, so you just have to pay attention at all times, or ride on closed course trails that are well-maintained so there isn't as much/any risk that way. This bike is awesome. I have tested several competitors e-bikes some from makers you would recognize immediately and which cost more than this Jupiter Bike Discovery X5. I will just say that I have tested (and returned) all those other e-bike offerings, because those bikes could not pass my acid tests, but this JupiterBike Discovery X5 is the Spirit of St. Louis in my world - the first one to pass all my tests - and a winner, and a keeper, and it's good even for tall riders who weigh up to 265 lbs., and that's a very big accomplishment by the team at Jupiter Bike. Hats off to them, good job! Very grateful for this bike and very impressed. My regular ride is a Chevy Silverado 2500HD LS 4-door Fleet-side 8'+ cargo bed, so it's a fairly big p/u truck, and it now costs me over $125 at the gasoline pump each fill-up. I was looking for an e-bike that would handle my 6.6 mile each way, 13.2 mile roundtrip commute each day on mostly flat terrain with a few gentle hills WITHOUT a recharge (my employer doesn't allow charging of employee devices inside the building) and this bike meets all the requirements as described in this review. Sometimes after work, I prefer to go intermodal and just throw the bike on the city bus, and I can do that too with this bike if I want. I paid about $729.57 including all tax and shipping total out the door price for this bike new from a well-known national retailer, so this e-bike used on my commute, figuring in some rain days when I won't use it, will pay for itself in less than 6 months, and it helps the environment to leave my Big Iron Silverado 3/4 ton p/u in the garage for the short commutes such as to/from work, to get a haircut, etc. Jupiter Bike Discovery X5: Awesome!

   Great E-Bike

By guider.thomas1 on April 05, 2022

So I will admit in the beginning I was a little skeptical as I'm pretty new to electric bikes however this bike is a great little bike. It gets me to and from work. I had a slight battery issue and the sales team handled it quickly and got me the new battery as fast they possibly could. (Less then 1 week). I am very happy with my purchase.

   Great for the plane

By dstocker on January 01, 2022

We got a couple of the x5’s to go in the Cessna 182. They fit on the rear seat, so easy to fold and unfold. Landed at Half moon bay today and rode into town for lunch. So easy. Looking forward to the bags, will make it one step easier. Nice.

   love the bike!

By pezwat on December 10, 2021

The bike is the best! Unfortunately it came with a flat tire. The staff at Jupiter were very helpful. Megan walked me through my options and I was riding it later that day. Couldn't be happier

   Best electric bike on the market.

By Frank D. on November 26, 2021

We bought 2 Jupiter Discovery bikes and sold our pedal forward Trek bikes. We have yet to run down the batteries and we take them on our RV trailer. They are easy to peddle, have three perfect speeds, and hold up very well. Everybody loves them, and the bikes withstand abuse very well...They are less expensive than most Ebikes, yet perform so much better. This is a well kept elite secret.

   The Discovery X5 is the best e-Bike IN THE WORLD!

By djbreslin on November 09, 2021

All of their other models should be this simple. No gears needed with a 350w motor! Very powerful! Prefer this model over all their other models. Wish it was maybe 5lbs lighter, Belt driven, and $500 price point. Perfect set of features! I can't emphasize enough you don't need 6speeds, single speed + motor is all you need. Make them lighter weight! No other value e-bike comes close, PS I'm 6'5" 200lbs and this is a daily comfort rider for me!!!! WELL DONE. Carbo is the only better e-bike in the world and it's 4X's the price.
