    • 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

    • Best "Chinese" product I've ever bought.
Color: Q20-1500W 48V 20AH
The media could not be loaded. I waited a year to make a review, and I can confidently say I love my bike. I've had it a year on the 29th of July. (Couple weeks shy) and this bike has been flawless. As of this review, I've put on 289 miles on it, not a TON of miles, but most of them are off road and on trails. This bike has been great. A full charge lasts me hours of riding. I have yet to fully deplete my battery on multiple hour long trips. Typically 20+ miles and still have half life on the dash. This is all throttle controlled, no pedaling on mostly flat ground. If I was pedaling from start to finish, I am confident I could get nearly 100 miles on a full charge. For reference, I'm 180 lbs. 6'2". I often let my 8 year old ride with, and she is 60 lbs and the bike handles us on and off road no problem. Hills require momentum or downshifting and some effort. There's are few cons, but minor ones. Suspension is very stiff on the lowest setting. Does not have much travel. But plenty for regular riding. The seat is a tad too stiff also. The motor makes a rhythmic humming noise, but has been this way since day 1 and doesn't seem to be of any concern besides a minor noise. The gearing of this bike is too low, it's only 7 speeds, and at full throttle, or full assist, you can't keep up. The bike needs at minimum, 2 more speeds. So at full speed, you basically just ride it like a motorcycle. Not really an issue, but if you're trying to ride fast and save battery by pedaling you can't. In order to maximize your range, your only way is to ride slower. (19 mph or so) At full speed, full charge, I've been able to touch 34 mph (GPS verified) which is MORE than enough. It's fast enough to feel dangerous on sidewalks. I personally ride on the streets when there's no bike lane, I wish it had mirrors, but that's a small detail and not really a flaw. Overall I love the bike, and I'm considering getting a 2nd one and handing this one to my oldest so we can ride together. ... show more

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. ... show more
