  1. L***a

    This bike looks amazing and performs even better. I’ve gotten so many compliments on it already.

  2. J***n

    This bike is a beast! The fat tires and powerful motor make it perfect for off-road adventures.

  3. F***o

    The build quality of this bike is top-notch. I can tell it’s going to last me a long time.

  4. R***n

    The fat tires on this bike provide excellent traction and stability. I feel confident riding on any surface.

  5. G***i

    I was hesitant to buy an electric bike, but this one has exceeded my expectations. It’s so much fun to ride!

  6. B***n

    Nice bike
    I don’t know anything about E bikes. First one. This bike is fun to ride. Package that it was shipped in was great. Easy to put together. Lots of power. Welds on frame look great. Brakes are great. Looks well made. Great bike for the money

  7. J***n

    The battery life on this bike is impressive. I can ride for hours without worrying about running out of power.

  8. E***c

    The 48V battery on this bike is a game-changer. I can ride for miles without worrying about recharging.

  9. D***g

    I ordered two of these bikes. At first I had a question but once the communication started they have been great to work with. I love the bikes and get a lot a great comments on them. They are pretty easy to assemble as well. I have had fun adding accessories. I would highly recommend them.

  10. D***d

    The large battery on this bike is a game-changer. I can ride for hours without worrying about running out of juice.

  11. M***o

    I love the Shimano 7-speed system on this bike. It makes it easy to switch gears and tackle any terrain.

  12. C***r

    Very Nice Ebike for The Price

    I’ve racked up over 100 miles on the SIVROCK now, and it runs great. The battery is a lot better than I expected. I can ride 20 to 40 miles on it, and it goes up to 29.6 mph, but most of the time I do about 20 mph. The gears and shifting are perfect – shifting is really fast and smooth, one of the best features of this bike.

    I watched a few YouTube videos from bike reviewers, and they were all really impressed with this bike, which is why I bought it. I’m really happy with it. I also have an Onyx RCR, which is a great addition to my collection. You can’t go wrong with this one.

  13. A***o

    The suspension on this bike is excellent. It absorbs bumps and makes for a smooth ride.

  14. G***e

    The Sivrock Ebike is a great investment. It’s so much more fun to ride than a regular bike.

  15. P***k

    Le falta un poco de potencia
    Esta muybien ymegusto mucho

  16. D***d

    Nice e-bike
    Just finished my first ride, 30 miles. This bike is awesome.

  17. S***d

    This bike is huge and robust – seems very solid. Recommend also getting side mirrors – you WILL be riding on roads with this bike.

    Full assist mode is effortless of course – if heading uphill for more than a brief stints you may need to gently pedal at high gear to help it out, but other than that this bike has plenty of power.

    Fat tires make it feel even more like a motorcycle. Very large, solid and fun. So far so good!

  18. T***y

    Easy to peddle with peddle assist
    Peddle assist really works. while coasting with no hands on the bars, bike is smooth with no problems. Once you start to peddle the assist engages and moves you forward, big surprise with no hands on the bars. It is that powerful, and feels like the bike will move out from under you, so hang onto those bars!!

  19. ***r

    At this point I’ve only had the bike for 2 weeks, but I find myself riding more than I ever did with a traditional mountain bike. I am a big guy at 6’5″ and 275 pounds. First, It’s definitely high enough. Then, it seems as though my size doesn’t matter to the bike; it has plenty of acceleration and speed. I hit 25 MPH on it. Impressive! I’ve ridden a half dozen times and the battery life has barely dropped, that’s impressive also.

    Ebikes are expensive (as you have seen by now) and to tell the truth, I was looking to get by as cheaply as I could, which is why I bought this one. I was not disappointed.

    Granted, the bike is till new, but it hit all the right points. Good price point, good battery life, easy to assemble, good speed and acceleration (even for a big guy). You can’t go wrong here.

  20. R***e

    We ordered 2 of these bikes. They arrived when promised. They were easy for my husband to assemble without any additional help. The bikes appeared to be good quality with lots of bells and whistles. We were pretty impressed!

    Based on our experience, I would recommend this bike, not just for the quality but also for the customer service we received.”

  21. H***v

    This bike is sound..the fat tires and shocks make it fun when we go off roading..i researched several bikes and this was the best deal I could fine so I bought a second one..the led light is great for night riding. all around great bikes…we love them…and you will too..

  22. N***s

    Great Gift
    Originally bought as a gift for my father. It is a great bike and all. Unfortunately we could not keep it as it was just slightly bigger for a transit bike rack. No other issues. Do recommend

  23. J***s

    Great Bike
    Bought this for my daughter for Christmas. She’s been wanting one for a long time. Was very easy to assemble. The box it came in was amazing and was delivered with care. No complaints at all. My daughter finds any excuse to take her bike rather than drive her car. Now she needs baskets. Very smooth ride and lots of fun. I have even considered getting one for myself.

  24. B***z

    It went together easy enough. Took my first short ride today and it seemed to work fine. It was almost too much fun and its a big son of a gun. Im 6″”4 and this bike is a good fit with the seat up 2 inches. Everything works as it should.
    I will check back in 2 weeks if all goes well until then.

  25. ***.

    Do you want to foray into the world of electric bicycles? If so, then this is a great bike for you. It’s fairly easy to assemble, easy to follow, step by step manual. You are even sent a “swiss army” type tool for every screw, bolt and nut.

    The ride is smooth, the power is respectable and the controls are easy to read. The only thing I changed was the stock seat for a gel seat, added a rear turning signal light and additional reflectors on the 26in wheels but without those things, I would have still been happy.

    The customer service is great. I had a minor problem and they stayed in contact with me through email to get it resolved quickly.

  26. D***t

    This is a great E-bike for the price. I have owned/ridden this bike for the last 2 months. It has plenty of speed around town and the battery lasts for a while. I no longer own a car and with the 50 liter saddle bags, I can do all the shopping I need for my self. I have also added mirrors, rear turn signal/horn/brake/alarm light bar.

  27. X***p

    Absolutely amazing bike. Great price point. I was amazed about how it was so perfect right out of the box. The bike has tons of power…I ride it 4 miles each way to work on our trail system. I rode a fair amount of bike…and was skeptical about getting an e-bike. Turns out you do in fact get a mild cardio workout while not getting sweaty. Best of both worlds. Hills and wind no longer exist.

  28. T***f

    I have been considering an e bike for some time and looked around at the high end units that cost thousands. I bought this one just see if would enjoy it before I dumped a bunch of & in a high end model. I’ve only had it a short time but I am loving it. My only recommendation is that you should be prepared to spend some money on tire protection if you live out in the sticks like me.

  29. M***f

    First of all the bike has tremendous power not to mention it’s so easy to use all the controls. I also like the paint job and the way the bike looks it’s beautiful I couldn’t be happier. I also like that the battery uses very little power on a 5 mile ride, it only dropped one bar, and I used full electric almost all the way. I made a very good decision to purchase this bike. I am very happy with it. Thank you.

    Exactly what I expected.
    I don’t usually write reviews unless it is deserving, positive or negative. So far I have no complaints about this bike. It is fun to ride, with plenty of power. The assembly was fairly straight forward, it took about 30 minutes to finish. It is exactly what I expected.
