Dual Motor Electric Bike for Adults 2000W 52V 40Ah Batteries Dirt Bike, 35MPH and 180 Miles, 20'' Fat Tires, Full Suspension, Shimano 7 Speed E-Bike, Bicicleta electrica para adultos Black

The bike is very nice and sturdy, I did have a problem with the throttle. Defective but the seller and customer support sent me a replacement at no cost and it's working well now, I appreciate their fast help, thanks very much for the care, I bought a different no name ebike on here before and the throttle never worked then the wires for petal assist snapped because the crank came loose what a waste... instead buy from these guys! They care..buy Ridstar!!

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 farCons- 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 issueOverall, 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.

Update- customer service consistently reached out and have tried to make amends. Which in happy with.Only had this bike for a week. Got it for my son. Had Amazon put it together. Thought it was a good bike until... Front wheel came off. I'll blame the installer for that. But something is wrong with the brakes. The front brakes makes an awful sound. Not a squeak sound but something loud. And the back brakes have to be pressed really hard. I've tried to contact someone but I haven't hard any luck. One person said I didn't buy it from ridstar!!!

As soon as I opened the box, I noticed the kickstand was broken. Since the bike is quite heavy and I didn’t want to risk it falling over without a functioning kickstand, I held off on riding it and waited for the replacement kickstand to arrive.In the meantime, I took the bike for a few short rides around the neighborhood just to check if it’s working fine and check for any issues like brake alignment, etc. Unfortunately, during those brief rides, several plastic components started to break. First the phone holder, then the finger paddle, and finally the throttle. Once the throttle broke, the bike became completely unusable.I reached out to the seller, who responded by offering to send replacement parts. However, as the photos I’ve attached clearly show, these are not simple parts that can be swapped out easily—they require professional installation. I told the company that this situation is unacceptable, but they’ve refused to offer a refund or send a replacement bike.I paid over $1,000 for a bike I haven’t been able to use properly even once. I don’t understand why I should be responsible for taking it to a repair shop to fix issues that were clearly present from the start. The product arrived defective, and I feel I’m being unfairly held responsible for their poor quality control. I’ve been going back and forth with the company for over a month now since receiving the bike, and they still haven’t provided a proper solution. They’re saying it’s not easy for them to send me a new bike due to shipping costs. Well, I don’t care what you’re gonna have to pay for shipping. I just need to have a working bike when I paid for one.If you’re considering purchasing this bike, I hope you’re fully aware of the risks you’re taking—not just with the product quality, but with the lack of support you may face if something goes wrong.

Assembly directions are awful. Be prepared to do a lot of figuring things out. Thankfully, I had the help of my awesome, mechanically inclined Dad! Once assembled, the bike is GREAT!Drawbacks:1. Am seeking an add on rack for gear, shopping, etc. Doesn’t seem to be one associated with this particular bike.2. Pedals like a BMX, so if you’re not comfortable with that, make certain batteries are charged.3. Rough ride over bumps, not much give in the suspension.4. Seems to have cruise control but can’t figure out how to use it (again, terrible directions for use).The good news:1. Rides a bit like a dirt bike and can handle dirt, grass, and pavement. Particularly great ride on a smooth road.2. Long, wide, comfortable seat. This is one of the things that I was looking for as I find most bicycle seats very uncomfortable.3. Good battery life.4. Good speed.
