  16. 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.

  21. G***e

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

  22. 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!

  23. ***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.

    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.”

  25. E***z

  26. H***v

  27. G***s

    Best bike i’ve owned and would recommend it to anyone. Have had many great comments from people just stopping and looking at it. Easy assembly.

  28. ***r

    Can I say, awesome awesome choice for an E-bike if this is your first time. Man, this bike is amazing! Had a great ride with it my first time, I was stunned at how fast this thing can go. The speed almost reminds me of a motorcycle. I’m just thankful my county lets me ride on the trail.

    Seller was very proactive in helping you out, you will need to stay in touch just to make sure everything is calibrated correctly.

    Overall, im floored over this bike. I’m just a little upset about if I’ll ever get to riding my other bikes. The fun this bike can give you is addictive. So, to sum up, this is a great choice for an introductory ebike.

    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.

  30. ***.

    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.

    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.

  32. 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.

    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.

    I highly recommend this company to anyone looking for an E-Bike. Not only is the bike better than we expected, the company goes above and beyond for their customers. Our bike was stolen from our property and I couldn’t find the paperwork with the serial number, I reached out through here and they responded quickly with pictures of the serial number. I reached out asking where I can buy replacement parts and they have been so incredibly helpful!

    I bought this bike for my significant other. He has been riding it almost daily. So far it works perfectly. He enjoys riding it!

    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.
