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.

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 Jupiter Discovery X5 E-Bike. I've put hundreds of miles on it this summer.

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 fine 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!

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 Jupiter 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 JupiterBike 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 JupiterBike 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 JupiterBike 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 JupiterBike. 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. JupiterBike Discovery X5: Awesome!
