🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.

The reviews of this eBike paint a largely positive picture, with the bike providing quick, smooth rides powered by a reasonably potent battery. Buyers appreciate the easy assembly and the efficient suspension which yields great handling on all terrains. However, there are some discrepancies noted in the advertised specifications and the bike's actual performance, particularly concerning the power output and battery capacity. Despite these concerns, the bike is regarded as good value for the price.

Pros

  • 🚲 Easy assembly and ready to use upon arrival
  • 🔋 Good battery range, providing up to 38 miles on pedal-assist mode
  • 👍 Excellent design and build quality, offering comfortable riding
  • 💨 Capable of decent speeds, with a reported max speed of 28mph on flats

Cons

  • ⚙️ Some perceived discrepancies with the advertised specifications, particularly concerning the power output and battery capacity
  • ⏱️ Display does not feature an elapsed time feature
  • 🛠️ Shifter may require adjustments, had trouble finding 6th gear as stated by one review
  • 🔑 Battery removal and replacement can be a bit finicky

Should I Buy It?

If you're in search of an affordable, sturdily-constructed eBike, this bicycle may fit the bill. It provides a good balance of speed and energy efficiency, perfect for both casual rides or longer distance commutes. Take note of potential disparities in power output and battery capacity, but if these concerns are not high priority and you don't mind taking a hands-on role in making small adjustments sans customer support, this purchase could be worth your consideration.

    • Great product
So happy with this purchase. Easy to put together, it had a bent brake rotor and I reached out to them and they had me a new part right away. Would highly recommend!!! I got this to follow my kid around on his dirt bike and it does the job!!

    • Nice eBike. But performance doesn't add up to claims.
The bike shipped relatively quickly and I was happy to see that it arrived with the battery, so for me at least, there were no delays in getting out on the road once the bike was assembled. Fortunately, the box arrived in good condition, with no signs of shipper or warehouse abuse. Everything inside was well packed and protected, no scuffs, dings or paint issues to detract from the sharp appearance of the bike. Assembly was straight-forward and the included tool kit covered pretty much all of the tools required to complete the process. The brakes seem to be adjusted well out of the box and have no problem locking up either tire without rubbing while riding. The shifter, however, doesn't find 6th gear, so I'll need to tweak that still. But honestly, unless you have very little power in your legs, or are pedaling up the steepest of inclines, shifting is pretty much unnecessary with this bike even on PAS 1. While I haven't verified this yet with GPS, the speedometer reports a max speed of about 28mph on flats. This can be locked to a lower speed within the bikes controller settings. Now here is something which potential purchasers should know about this bike, and perhaps all bikes of similar origin. Just because you see a similar looking bike out there with another manufacturer's name on it, it doesn't necessarily mean that you will be getting the same bike when you buy it elsewhere, even if there is no difference in advertised specs. Sellers of Chinese imports, more often than not, will think nothing of just re-labeling components with better ratings to try to compete with higher-end (and usually higher-priced) offerings to try to get that competitive edge. After all, a sticker is nearly free, compared to using components with the actual capabilities printed on it. Unlike other ebikes offered in the past with this frame, this bike does NOT use the popular BAFENG hub motor. Rather, one from a relatively unknown company named WUXI TRUCKMOTOR, who has only one motor type rated for 48v on their website and that motor is also rated for 500w. While it is possible that this uses a customized offering from that company, I will say that in my experience with these types of items, it is unlikely. But the thing with electrical items is that it's pretty easy to flesh out the truth. For instance, the wattage shown on the display of this supposed 750w ebike NEVER goes above 632w, even with a full charge and scaling a hill so steep as to slow the motor almost to a stall. This should not be, as a 48v motor with a controller limited to 20amps should be able to deliver up to 960watts, limited only by the battery's ability to provide current and the motor's ability to shed heat. So while it would take further investigation to figure out where things are being limited, it's not difficult to see that the actual performance is nowhere close to what is advertised, IF the controller display is accurate in it's reporting (and yes, I have confirmed that it is configured properly.) Again, current meters are pretty basic stuff, so no reason to doubt it. The battery is manufactured by a company called "Suzhou Juyun New Energy Technology Co" who, according to their website, uses cells from Samsung, Lishen and HLY. What's in this battery? Can't know without opening it, which I may eventually do, but don't assume that they are Samsung because other similar-looking ebikes indicate this. The battery weighs just over 9lbs, including the case, framework, BMS, locking hardware, etc. Using "middle of the road" estimations for power densities of common use "NMC-type" Li-Ion batteries, 720wh (48vx15ah) should weigh about 8.5lbs. Somehow, I doubt that all of that extra material only weighs 8oz., or that the cells are "Tesla Quality". Couple that with the fact that at the 632w max draw this bike seems to be capable of, one should be able to ride for over one hour on max throttle with no pedaling, which based on my last 10+mile ride it absolutely couldn't do, the "15ah" claim should probably also be taken with a large grain of salt. I would not be surprised if the actual usable Wh rating is 500wh or less, which is more in line with 11.6Ah text in the marketing material and which conflicts directly with what's on the sticker and the product description from the seller. In other words, if you are hoping that the marketing material is old and the product has been upgraded, it probably hasn't. So yeah, the bike is nice, and probably worth the price (provided you get it on a good sale for ~1300.) But if you think you are getting a great deal based on the specs, then you are likely falling into a trap. If you want an eBike with the specs shown for this one and weigh more than my 180lbs, I suggest you keep looking. This one's probably not for you. Otherwise, it's a looker and will do the job for short-trips or long ones with lots of pedaling. ... show more

    • High quality
This product is more than wonderful. It looks beautiful and its quality is durable. My son was happy with it, but I faced a problem. The battery was broken. Perhaps the reason was during shipping. I contacted the company and the response was fast. I explained to them the problem and they sent me a new battery. Their treatment was very nice and they responded quickly and were patient. And you understand, I have not regretted buying this product and I highly recommend it and rate it ten stars 😍👍🏻 ... show more

    • If you don't want the hassle, don't buy from this company
Theres actually nothing wrong with the bike. It looks nice and works well. My problem is setting up the display. The PAS 1 speed is way too fast for just cruising. I thought it would be easy to just get some support for it. The contact numbers for this seller are personal numbers. No one answers the "chat now" on their website. I don't have much faith in their email at this point. I looked all over the internet for this particular issue and there is nothing I can find to help me. So if you don't want the hassle of simply understanding how to change these settings on this bike. Go with a more reputable company. This is the 2nd "ebike company" I can't get any support on. ... show more

    • It's a blast!
Just put my first 100 miles on it and it's been great so far! I have been doing some serious hills and still getting about 20 miles on a charge. I have not tried it out on the flats, but I will update the post after I do that. I have been able to get it up to 32 mph downhill and about 27-28 on the flats! It is seriously a fun bike. I get all kinds of positive comments from people when I am our riding! ... show more

    • Seat height
Nice bike for the money. The seat and frame is a little too tall for a average size person. More suited for 6 ft and up.
