All of the components are definitely on the lower end of MTB parts, but are name brand. I wouldn’t recommend buying this unless you feel comfortable doing basic mechanic work.
So this is my first electric bike, but I’m going to apply the same logic that goes into buying your first dirt bike, 3D printer, or really anything this has a learning curve. Buy something that comes out of the box needing to be tinkered with, it’ll expose gaps in your knowledge and force you to learn new skills. This bike seems to be perfect for that. Out of the box the brakes had slight issues, the tires probably need to be trued, and energy management to solely down to the user. Everything in the box has the potential to work flawlessly but it’s on you to make that happen. If you want a bike that is 100% out the box look elsewhere, if you actually want to know how the bike works and how to improve it this is perfect for you.
Also, I will note that I haven’t been able to unlock the governor using P08 like you can with other bikes. The option is missing from the controller, but honestly for my area I don’t need it.
For the price you really can’t go wrong, all the issues I’ve had can be fixed easily by watching a couple YouTube videos. I’m not great at writing reviews, but I’m extremely confident with this bike, been commuting to work on it for a week, have taken it on a long ride, and have done some trail riding and the bike hasn’t flinched.
I’ve also gotten a lot of compliments on its looks, glad I went with the Black/Red paint.
Protip: Holding the minus(-) button while maintaining speed turns on cruise control.
Photo notes: I have added a tail rake and a more powerful light.
I bought this bike in the hopes of getting me back into shape, and in the hopes that it would get my biking muscles and lungs back to where I can conquer the surrounding hills all around my home and area.
Well, I am very impressed with this bike and it's pedal assists features. It truly helps the rider traverse long and steep hills with a significantly less effort. So, the rider still gets a good workout, without all the pain and agony of an all human powered Hill climb.
This bike came very well packed and in a very robust box. The bike is over 50lb, so lifting it out the top of the box may not be doable for many people to do it alone. It comes mostly assembled, but what's left to assemble may be a bit challenging for those not mechanically inclined. There's always the option of paying a bike shop to do this for you, which is probably ideal for the sake of safety in a properly assembled bicycle.
I have a lot of experience working on bicycles, but by the time I was done assembling and fine tuning everything to my preference, it still took well over an hour from start to finish.
The battery was still nearly fully charged,out of the box. I did a quick test run and everything worked perfectly!
I've now had the bike for a couple of weeks, and I could already tell that my body is getting stronger at cycling, again. Less pain and soreness and I'm getting more and more comfortable with the bike's handling and my own road cycling mentality.
For the overall quality of this product, the total cost of just over $400 is truly impressive, and an absolute bargain!
Can pedal when battery dies- awesome to ride and looks cool
YOU do the math. They refused to help me in any other way. Wouldn’t get me a gift card, wouldn’t refund me to a different card or bank account. Nothing. I ended up having to call Amazon and this issue was taken care of within 15 minutes..
Update March 13, 2025: So far, I now have put about 30 miles on this bike. I like power assist and throttle controls. It is somewhat responsive, but lags slightly in pedal assist kicking back in if you stop peddling and start again. Powering up hills is very good in power assist. Haven't tried in throttle only up hills. The battery is about 8 lbs and is a little tricky to place in its position on the bike. The disc brakes are more than adequate and mine don’t squeak. I had to adjust the front ones since they were rubbing, so be prepared to do so if that is the case. Plenty of YouTube videos of brake adjusting.
Ride and Comfort
The ride is acceptable but can be teeth rattling on uneven terrain at higher speeds. I find that’s where you get what you pay for. Although totally acceptable beware bumps can be harsh especially at higher speeds. The front shock absorber helps but is not the best. I mostly ride in power assist 1 or 2 and push it to 4 or 5 uphill. Going uphill is what this bike does well. I never used throttle only for hills.
Battery Life and Controls
So far after riding 21 miles on power assist 1 or 2 and sometimes using power assist 5 on a few hills it used about 50 percent of the battery. The battery display shows bars that don’t always corelate to the bars on the battery itself. Where the battery on the dash would show 2 out of 5 bars the battery would show 4 bars out of 5. Also, the dash shows remaining voltage which is an indicator of the battery life.
Conclusion
For the money you cannot beat this bike. The bike is a higher quality “cheap” bike if that makes sense. It is very fun to ride, and I think the range is there if you take it easy. Where it lacks torque the motor and battery have power.
Also, if you have any issues with assembly, you can find the assembly video on Youtube. I can't speak to the durability of the bike, but it has been a load of fun so far. Very powerful. Smooth.
Other than that, it's AWESOME. No other complaints (the thing MOVES).
Edit: the left pedal has come loose at the arm and does not remain tight after hand tightening. I looked it up and it looks like I will need to take it in and get it tightened by a torque wrench. The part of the pedal that’s loose was not assembled my me, it came preassembled.
Excellent power, good battery life, good features such as handlebar riser, palm rests, easy to read and use LCD, nice looking and very fun to ride.
It rides great on level ground with battery off, which means it rides nicely as a regular bike. Having it be electric is a bonus when needed.
It has 21 speeds for which i know nothing about. i keep it in 3 or 4 when battery is not in use and it's perfect for level ground.
In fact, i never shift gears at all other than switching between PAS modes.
It has 5 PAS modes. i rarely need to go beyond 3 between 10-45 degree inclines.
Of course this may very per person based on body frame, health and strength.
Cons:
Brakes squeal badly and makes coasting downhill less enjoyable.
I have to brake softly all the way down hill in attempt to avoid squealing and from everyone looking at me (lol). In due time i may research to see if a better braking pad is available.
Also, your foot can sometimes hit the kickstand while pedaling due to location and size of it. If your a big guy with big feet, may want to be a bit concerned about this.
Summary:
Aside from the brakes, this is a very affordable ebike and good for the money. I did moderate research before purchasing and hoped it was what i expected.
Turns out it was! I'm very happy with the bike. I'm yearning to ride on weekends.
Hope this helps those scouting for an ebike.
Further, I tested the front light as instructed by the user manual. To do so, I had to turn on the ebike, but the manual doesn’t mention how to do that at the point of installation. Yes, there is a red switch on the battery, but it took me a few minutes to figure out that I had to press and hold the power button on the LCD display as well. The manual should at least mention where to find the instructions on how to turn the ebike on or mention this early in the assembly section, not 5 pages further in on page 15 under Display Controls. Still, I managed to complete the setup of the bike after these minor hurdles. The bike includes front and rear disc brakes, 26-inch wheels, a locking front shock absorber, and a headlight. It weighs 49.6 lb, according to the manual. Despite its weight, I can reach over 21 mph in less than 10 seconds.
Afterward, I wanted to charge the battery but saw that it was almost fully charged, so it took me less than one hour to fully charge it. The LCD Display, in my opinion, functions like a bike computer, providing quite a lot of information. I can see the odometer, voltage data of the battery, the distance of a single trip, battery status, and assist level, which is the current power assist level. To increase the pedal assist level, I press the plus button, and to decrease it, I press the minus button. I can toggle between the odometer, trip distance, and voltage by short-pressing the power button. It’s from the LCD Display that I can also turn the headlight on and off and sound the horn, which is quite similar to a car horn. I can even adjust the brightness of the backlight and set the bike to turn off automatically after a certain period of inactivity, ranging from 0 minutes (meaning it stays on continuously) to 60 minutes. I can also reset the odometer.
After learning all these controls, I got familiar with the ebike's five riding modes: Bicycle Mode, Pedal Assist Mode, Throttle Mode, Cruise Mode, and Booster Mode. In Bicycle Mode, I can pedal the bike normally without turning on the LCD display - it’s equal to riding a regular bike. In Pedal Assist Mode, the motor provides extra power as I pedal. I can choose from five levels of pedal assist, depending on how much assistance I want, and the bike always starts at level 0 to avoid any accidents that might occur if I accidentally twist the throttle. To use Throttle Mode, I turn on the LCD display and select a level. Then, I just twist the throttle to control my speed without pedaling. If I want to maintain a steady speed, I press and hold the minus button when I’m going faster than 6.2 mph. When the display flashes the P icon, Cruise Mode is on, and the bike will maintain that speed. However, if I twist the throttle or apply the brakes, Cruise Mode automatically turns off. Booster Mode allows the bike to move at a speed of no more than 4.2 mph when I activate it by long-pressing the minus button. The display will show the P icon again, and like with Cruise Mode, Booster Mode turns off if I squeeze the brake.
I quickly realized how much the ebike improves my daily commute. I use it to avoid public transit since I can easily reach my workplace by riding through safe residential streets and roads. My commute is now less hectic than dealing with crowded or late buses. Riding the ebike also saves me money. I no longer need to spend on public transport, and when compared to driving, I save on gas as well. I don’t miss the stress of finding parking or sitting in traffic jams, either. Plus, the ebike gives me a bit of exercise without overexerting myself. I find that using Pedal Assist Mode lets me control how much effort I want to put in.
I always use the bike for short trips. I’ve started using it for running errands, like quick grocery trips or visiting downtown. It's a relief I don't have to worry about traffic or parking. When I’m riding on longer, uninterrupted stretches of road, I often switch to Cruise Mode. It keeps my speed steady, and I can relax without constantly having to adjust the throttle or pedals. In my experience, the ebike is intuitive to use.
Nonetheless, there’s a bit of routine maintenance that I do to keep the bike running safely, particularly with the battery. I charge it after each ride fully, although it rarely drains completely since I’m not using the motor at full power all the time. I noticed it charges quickly. Most of the time, the battery reaches full charge in a few hours. Additionally, once a month, I discharge the battery completely before recharging it, as instructed by the manual. I hope this maintenance step prolongs the battery’s life and keeps it working optimally on every ride. So far, two months have passed, and I haven't experienced any issue while riding.
I could have afforded a top-of-the-line bike, but I didn't know if I'd like it, or if I would use it regularly. Perfect for my needs.
One issue: The chain derailer, which is used to switch gears, may need to be adjusted. The chain strikes the derailer while it's passing thru in some days.
Seems to be getting quieter... May just need to get "broken in". Time will tell.
In the meantime, I luuuuv this bike!!
The bike itself works great, it kicks up to 21 mph very quickly. To anyone who hasn't ridden an ebike before, my best analogy is; When pedal assist is on, it feels like going downhill all the time. Very fun. My dad who is older and can't really ride like he used to is enjoying this bike immensely.
The only complaint I do have at this point, is that the seat is very uncomfortable, we had to switch it out with the one from our previous bike. Aside from that though, everything is great.
Would recommend.
Thank you team!

Delivery was quick and the bike came very well packaged. Putting it together was a breeze, took less than 30 minutes, and the instructions were really clear and easy to follow. Every tool I needed for assembly was included also!
It’s a really fun and easy to use E-bike. I’ve ridden it for more than 150 miles, on different terrains, and it has been great. I haven’t had any issues and I’ve ridden it in both sunny and rainy weather, and it has held up fine. The gears are top notch (Shimano) and the brakes are dual-discs. The 750W motor and 48V battery pack a punch and allow for all levels of incline I’ve tried. It has a screen display for battery level, speed and trip length too.
The adjustable pedal-assist works smoothly and I can go up to 25 mph when I am on flat ground with electric help. The battery lasts for about 30 miles on a charge if I use the electric motor a lot, and almost 40 if I mostly pedal.
The bike is a bit heavy, especially with the battery, but from my understanding most E-bikes are. That hasn’t been an issue for me. All in all, I’m happy with my purchase. I had a knee replacement and it feels great to be able to ride a bike again!
