    • This Bike (Dual Battery, Dual Motor Version) is UNBELIEVABLE!

I don't even know where to start with this bike - it is amazing. I decided to spring for the dual battery version for a couple reasons - one was the increased speed. This bike is used as my main commuter in the city, so getting around at a quicker speed pays big dividends for me. What I didn't expect was the increased acceleration with both batteries running - if you're not pointing straight and you give it full throttle, it will easily break traction. This bike is great for going up steep inclines with minimal drop off in acceleration, including pulling me and my 30lb trailer and 45lb dog. The range is also very good - IF you're not blasting at max speed/throttle for the majority of your trip. What the dual battery version gives you more than top speed and acceleration is flexibility. You can choose to run just the front battery & front motor, just the rear battery & rear motor, or both combined. My top speed in single battery mode is 28mph and 34mph with both going at once. I can conserve battery by just running the front or rear, while saving the other for steep hills or the return trip if it's a long trip. You turn on the bike with an ignition key, then hit the power button. Each battery has its own power switch, and each motor also has its own switch. The bike also comes with 2 chargers - very handy. The brakes are hydraulic and stop the bike very nicely. The ergonomics of the bike are good as well. The seat is very cushy and gives ample room for preferred position seating. The seat height is not adjustable but at 5'11 the ride height of the bike is perfect for me. The twist throttle on the right feels natural and is easier to use and modulate than push levers on many other e-bikes. The light is bright and the bike also has turn signals for better visibility. The only thing this bike doesn't have, as one would expect, is room for much storage. It comes with a pouch that I use to house the phone & the handtool it came with. I only just managed to attach the lock on it, but anything else I'd have to explore some sort of basket attachment. Finally, the styling of the bike is very cool - motorcycle-esque. I've had zero issues with functionality of the bike. I've gone about 180 miles on it so far and have had no hiccups - my first e-bike had a ton of issues, so I'm very happy about this. TLDR: Pros - 34mph top speed, 28mph single battery & quick acceleration - Flexibility for speed or longer range - Comfortable & easy to use, easy to ride - Solid construction, high quality build - Has been 100% reliable in functionality so far Cons - Relatively expensive, though I think it is still a good purchase - Not a lot of room for storage - Very heavy (in part due to the thick construction) - Keys - one key to turn the bike on, each battery uses its own key to lock it into place, and if you include a key for the bike lock, that's already 4 keys dedicated to the bike alone. Add an apartment key, mail key, whatever else, and that's a lot of keys dangling in the ignition. Would have been nice if one key did ignition and both battery locks, but not a big issue Overall, this e-bike is everything I needed it to be. If you live in a metro and are considering an e-bike, this is the one to get. The speed limit in this city is 25mph just about everywhere, so I'm comfortable driving this on regular roads, bike lanes, and even sidewalks when open and I'm about to park it. I honestly don't see any reason to get a vespa or motorcycle over this, given the commuting flexibility this bike offers. Obviously, if you are taking long road trips on open highways a motorcycle would make more sense, but if you're reading this review that's probably not what you're looking for. ... show more

    • Defective Ridstar Bike - Bent Crankset Renders Peddling Useless

March 30, 2025: When I received this bike, I correctly assembled it according to the manufacturer's specified instructions. However, the crankset arrived bent and warped. The bike's protective foam packaging shows a dent where the crankset was pressed against. The bent crankset causes the chain to fall off when changing speed while pedaling, rendering the bike useless for manual riding. It has been four days since I received this bike, and support was no help in the matter. I clearly explained the situation to Ridstar, however they keep asking if "the bike was assembled properly". The crankset is not something that is assembled, it came pre-installed, however it was warped. If you are thinking of buying a bike from Ridstar through Amazon, think twice because I had a bad experience with their support and product. Update April 1, 2025: I have just received a response from Ridstar, indicating that they want to send me a replacement crankset so that I can fix it myself. Their response is inacceptable and ridiculous. I bought a brand new bicycle, it arrived broken, and now they want me to fix it myself. I cannot fix it myself, so they expect me to additionally pay a repair center to fix it. Definitely think three times before buying this bike- not twice. I wanted to attach a video, but the Amazon system will not allow it. I am claiming my total refund. ... show more

The media could not be loaded. (After 450 miles) It shipped and arrived on the prediction date. It ships from FedEx and you need to be there to sign for it, which I prefer so I know it’s safe. *You get what you pay for* Pros: - Easy assemble, if you need help watch a YouTube video - I’m able to hit 25mph and aswell get around 25 miles per charge (so barely legal Lol) - Fun off roaring, holds well but you need to practice a lot - Genuine good bike for the price, if you have more money I would just build or find a more expensive bike -Lots of room to sit and be comfortable, seat is great -Support is really nice, they will replace parts if they do break on their own if you show suffice proof, does take 1-2 weeks to get it which is the little annoying part - Solid battery, no real complaints, it takes a very fair amount of time to charge but does last me some time, I just charge mine at work anyways Now the bad, Cons: -Some parts are cheap, like the plastic ones, I broke my brake handle from dropping it so I recommend buying new brake handles, and: -Buy better brakes, the brakes they come with are ‘fine’ but I would invest in better brakes and it’ll be more comfortable and be safer, mine did break at one point - only a 250 pound limit, which is fine, but I weigh 180 and if my friend who is 250 rides it I have to worry about the suspension blowing up - my biggest issue: This is recent but either my controller or motor stopped working, they sent me a new controller asap to hopefully fix it, but if it isn’t the controller then it’s a new motor which can be expensive but I’m sure they’d replace. I personally just bought an entire new 72v motor kit w/ controller to upgrade the bike. Overall, great bike for the price, you need to learn how to fix things, upgrade, maintenance. But if you invest better parts then you won’t need to for awhile 3.8/5 ... show more
