    • Great Bike! But it's big!

Review Image by Amazon Customer Amazon Customer
I wanted to wait until I had 200 miles on the bike before writing a review to be able to give it a fair assessment. When this bike came I was a bit shocked by how big it was. We have a full sized SUV and folding it in half and putting it in the back is a bit of a challenge when you're alone. This 69lbs monster is difficult to wrestle with, mainly because there is no latching mechanism to keep it locked folded. I use a bungie cord to accomplish this now. As far as performance, this thing is awesome. This is my first e-bike so I have no reference to go on, but it is ALOT of fun. I have taken it mt. biking/going on trails in Colorado Springs and biking through Chicago and it handles well in either situation. The motor is strong, fast, and and I haven't experienced any drop-off in battery capacity yet. I did notice on some of my longer rides if you hold the throttle for too long the battery starts dropping pretty quick just to jump back up after letting it rest. With pedal assist 2 I have gone 42 miles and ended up with 26% battery remaining at the end. My only greivances/wish-list for the product are: 1. No electric tail lights, just a headlight. 2. The instruction manual leaves a bit to be desired. I wish the pictures were more high quality, or a website existed showing a step by step construction guide. I was a bit thrown off when I realized the shocks had two different sized bolts. 3. Wish there was a latch to keep the bike closed when folded. 4. Can't wait for more official OPEAK accessories to be released. I have had trouble going third party int he past and prefer to buy directly from the mfr. Overall, I am very happy with my purchase. Update: I have over 1000 miles on the bike now and it is still holding up. Had to change the tires and the disc breaks need some love, but other than that she's still going strong. If there has been any drop off in the battery it is minor. I just wanted to update to say that the pedal somehow came loose and striped out of the crank arm. I notified the company and they took care of the problem right away. I love good customer service. ... show more

    • My first ebike is a winner!
Color: UNIK - white Size: Medium
I have 187 miles, and so far only my kickstand screw loosened. THAT'S ABOUT IT! I'm not riding over rough terrain by any measure, but the roads in NY are a disaster, and the bike handles them very well. When the battery is charged to 100% it's a very fast ride. If you peddal it will go much futher without using much battery, unless you are constantly slowing down for street signs, etc... It has many features that I find impressive as newb, but I'm sure more advanced (expensive) bikes have better shocks, etc... these are very nice for what I use it for. The battery takes a bit longer to charge than I expected, but it doesn't bother me at all, because it's a powerful battery. Powerful enough to make it feel like I can use it often without having to constantly charge. FYI - LiPo batteries "regain charge" when you let them sit after use. If you run up the store, and use it to visit friends, get some quick exercise, you'll find this bike keeps it's charge very well. My buddy rode it and had a blast, but he partially disconnected a wire that plugs into the display. I thought it was hardwired, but it's a simple plug. Not wanting to fiddle with it, I reached out to support. They were incredibly nice, and certainly eager to help. I read other reviews that mentioned this, and hoped I'd never have to contact them, but I'm glad I did. Easy and fun to put together, plus it's a great looking bike. I'm am very happy, and if something changes I'll post an update. -R ... show more

    • Really Fun!
Color: UNIK - black Size: Medium
I give it 5 stars for fun, but ... Pros: It is a heck of a lot of fun to ride. I have had it up to 38mph in 5th gear with pedal assist. Keep in mind that it is a 60 lbs bike! I have put almost 200 miles on it in the three weeks I have owned it and it can go over a lot of stuff remarkably comfortably. It was pretty easy to put together other than dealing with the weight. It charged up well and consistently. The range is adequate for anything "around town" riding in electric alone (10-12 miles). With pedal assist, 20 miles is pretty easy to achieve and I weigh well over 200lbs. Would have probably given it 5 stars, but there were a couple of big cons that deserved the removal of 1 star. Cons : There is a U shaped metal bracket welded to the frame to protect the derailleur. It seems like a good idea, but mine was bent to the point that it was preventing the bike from shifting into its heavy gears. I had to physically bend it back out in order to use those gears. A real pain to do so because the power cord to the rear hub runs through it as well. Also, the hex wrench bolts loosen up way more than they should. At about 100 miles on the bike, my handle bars started rolling around 10 miles into a ride enough that I had to stop to find wrenches to fix them. At about 175 miles, the rear bracket which attached the rear fender to the frame snapped and the fender slid under my wheel 15 miles into a ride. I had to rip off the rest of the attachments to the fender and toss it in order to finish the last 10 miles of my ride. So, not perfect, but still really fun. Also, if you are planning on any rides over 25-30 miles, be prepared to ride a really heavy bike with no power. Good exercise, but not "really fun". ... show more

    • A good buy.
Color: UNIK - black Size: Medium
I call this bike "The Beast". The bike is big and it is heavy. It also has no problem getting me around and I weigh 230 pounds and my heighth is 6'1. The battery life is good. The suspension is adequate. The brakes are very strong and take a while to get used to. I placed a bigger seat with springs as the original seat is uncomfortable. I bought the two year warranty just in case. I added a side mirror near the forks and have a solar powered rear light. The front light is powerful. I have gone 70 miles with no problems. The price is quite fair in comparison to other ebikes. An E bike just makes riding a lot of fun with minimal effort. ... show more
