🚀 Abunda's Overview

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


The bike in review is an electric model lauded for both its on and off-road performance. Users find it reliable for daily commuting, durable under challenging weather conditions and effective at conserving charge. However, there are numerous mentions of the bike's high frame causing trouble for shorter riders. Additionally, some users expressed dissatisfaction with certain aspects, including difficulty in accessory placement, handlebar instability, and a weight that's on the heavier side.

Pros

  • 🚲 Strong performance in various terrains
  • 🔌 Effective battery conservation
  • 🔧 Users report durability in multiple conditions

Cons

  • ⚠️ High frame can be challenging for shorter riders
  • 🤔 Difficulty in accessorizing due to unique handlebar and frame design
  • 🌬 Handlebar stability issues
  • ⚖ Bike is on the heavier side

Should I Buy It?

If you're comfortable with a higher frame and a heftier bike, this electric bike is a fantastic option. Offering great versatility, commendable battery conservation and the ability to deliver performance in a variety of conditions, this bike impresses. However, if you're of shorter stature or value easy accessory installation, you may want to go for an alternative choice.

I have only taken this bike out twice and I have already put 48 miles on it and I am amazed at how fun this is to ride. I suppose I haven’t had it long enough to really see if there is going to be problems, but I am a mechanic and I can’t see any issues at all. The battery life has been downplayed, with minimal pedaling, the first day, I rode 22 miles and only used one bar of the battery life, and the same thing on the second day. I believe this thing will last at least 50 miles with minimal pedal assist. I really only got it for hunting so I can quietly get to my tree stands that are a half mile from my cabin, but I am having a blast riding it through town. I am very satisfied. I also bought an extra battery so I’m thinking this bike will easily make an 80 mile round trip. The price I paid was completely satisfactory especially since it was first advertised at $1800, the promo being just over $1200. Ohh, keep in mind that the bike is really tall and a little difficult when I have to stop and touch the ground, but when you are on it, the extra height feels awesome. Anyone with less than a 30” pant inseam should be a bit cautious, you won’t be able to straddle it very easy. ... show more

  • Beautiful piece of...
Upgrate breaks, shock, fork, rims and spoke pattern for weight/torque or this thing will crack. I'm 5'4 135lbs haven't taken it off road yet but I have 500 highway miles between 2 purchases. YES IS MY SECOND ONE. First bike the breaks failed and got hit by a car broke two ribs, the company refused to send me a wheel after 3 months so I returned it and a week later I got the wheel and no refund for another month so I bought a second one with my rent money because I doordash and this is my only source of income, got evicted waiting for Elf Inc and cancelled the order but they still sent it to the address I got kicked out from so I had to break in to retrieved the bike and had to lock pick it for it to start. Now they won't take it back because I don't have the original box so I'm homeless on a 1700 bike waiting to be robbed in Philadelphia. Thank you Elf Inc for the great experience. I rather my stools be quagulated blood than to deal with people like this but the bike looks nice am I right. I never wished wrong on anyone but dang I hope they go under. Amazon also said " I'm so sorry, and hung up on me for three months as I called every single day for help " The only reason I bought the second bike was because I had purchase a second battery as well as this one will give you 10-15miles on full charge tops. ... show more

  • Very good right out of the box !!
A lot of care taken in how the bike is packaged and packed for shipping. Very easy assembly and set up. I am 6ft 230lbs and this bike is almost big for me !!! Pedal assist is on point and love the quarter throttle. Fit and finish is outstanding!!! Will update after I put her through her paces.🚨🚨update🚨🚨9/20 I’ve got about 150 miles on this bike (I live 4 miles from work) and I have to say there are no complaints. Comfortable and smooth and of course fun !! ... show more

  • Decent bike fun with pulling the kids maxes at 1200 watts though
It’s a good bike overall, but the display shows a peak of about 1200 watts. Also every time you shut off the bike the clock does not keep working. So the clock is very annoying and always wrong. Yesterday I got 12 miles pulling my 2 girls that weigh about 100# together in a yellow buggy. I peddled the whole way on trails but the display showed 20% left at the end. Otherwise I’ve never maxed out the battery. The bike is Hefty at the company’s 77#’s. I bought it to mount to different pieces of equipment to help move from place to place. It works but is heavy when I need to lift it up a few feet. I can get 30-33 MPH from the display going down hill but it easily goes 25, and can get 25 when I pull the buggy as well. I need a spacer for the seat when pulling the buggy or it will drag on the tire, but that is an issue with the large tire and not a big deal. I really like the huge tires. As a farmer I have taken the bike into muddy fields and it stays above the dirt better than any other equipment I have. Overall a good bike, but still has some improvements that can be made. Added about 1 year in. The bike still works well, but can not run it for 15 miles with or without pulling something. I wish it had a better more standard connector, so I could easily add a second battery and keep going. 15 amp hrs is really not enough for a bike with 1200 watts or 1500 if you believe their advertisements. ... show more

  • First eBike
When this bike arrived in a well protected box with styrofoam wraps and blocks, I knew my money was well spent. It took me months to review different eBikes and the cost was one item that drove me away. I am six feet tall and thought it might be too small. To my amazement, this bike is huge. The response of the 1500 watt motor is crazy. It took no time to get my behind up to 28 Mph. I even took it off-road and still enjoy the power and handling. It easy to control and has plenty of power for me. After all, 28 mph is pretty fast on a bicycle. Besides being powerful, it looks sexy. The Snakeskin paint scheme is awesome. For my first eBike, I am impressed with what I purchased. Thank you very much for providing me with something fun and healthy. ... show more

  • DO NOT BUY FROM THIS COMPANY
This product was overstated, they claim the bike will go 31 MPH it only goes 23 on distance they claim it will go 15 miles in full electric mode, it goes 5 miles on a charge in full electric mode and you'll get about 10 miles in the pedal-assisted mode, it has no power to go up hills as they claim it to be an off road bike. on top of that, the instructions don't explain anything about the suspension. Dealing with the seller is a nightmare they are requesting I pay to ship back a product that doesn't even come close to their outlandish claims. Save yourself the trouble. I hope Amazon will be helpful in getting this vendor to pay return shipping although so far it doesn't appear that will be the case. ... show more
