Travelling to work sometimes requires more than one method of transport. For most of us, it’s driving to work and walking from the parking lot to that desk and seat we see way too often. Unfortunately for some people that walk is more like a marathon. Here’s where the Opia comes in, as it’s designed to help you get from to get you from point A to point B without having to break a sweat.
This simple foldable bike presents us with a seamless, one piece like frame. This is foldable with a slightly bigger mid tube to house the battery. The Opia logo can be found on both sides of the Metallic white frame, with some contrasting from the black; handle bars, seat post and chain wheel. This small package all sits firmly on those 20” wheels.
Onto the motor now, you can find a rear hub that is capable of providing a nominal 250W output. This is found at the centre of the rims wrapped in Kenda road rubber which is what you need for a commuter bike. It provides a more efficient system which is also helped by the fixed forks at the front. This all contributes to a very smooth sailing ride with some comfort from the large plush saddle. So it won’t leave your backside sore before you even start work. I get more into detail in the riding section.
The brakes that are found on this are front and rear V-Brakes. The front brakes required me to fit them out of the box, so the performance is subject to the rider’s ability to set them up. That aside, we’ll show the brake test which can be found in the video review. In the video, I talked about how E-Biking Now is going to try to standardize the brake test. There are still a lot of variables, however we’ll try to give you guys a more accurate representation of the braking performances of the e-bikes. To do this, the camera is set up to show 10m of the testing road and where I slam on the brakes when I enter the screen. From here, the audience can deduce your own thoughts about the brakes. But don’t worry I’ll also talk about it in further detail my riding experience.
So with folding bikes, I like to compare the ease and practically of the folding frame. The Opia uses the common design with a pivot located at the centre of the main tube locked by a simple clip. This was very easy to use, alongside the simple foldable pedals and handlebar. For more detailed look at the folding of the Opia, refer to the video review.
The other features equipped are an LED headlight and USB charging port from the battery. The Opia has a 36V 7.8Ah battery found in the frame with an opening on the left. This here allows you to charge your bike, charge your devices via USB and also contains the on and off switch. The rubber flap makes it simple and easy to access as well. One thing that I would’ve like to have seen on the Opia is a bike rack. If a small foldable bike rack could have been incorporated into the design that would made the bike an ultimate commuter. In saying that, there are mounts on the rear end that allows the addition of a bike rack.
At first the brakes weren’t that great but after bedding them in after a couple days of riding, it started to improve. They aren’t insanely responsive or powerful as you saw in the brake test. However they did stop around the 5m mark and keep costs and weight down. Basically, the Opia’s entire purpose is purely to get you from point A to point B, and if you need to stop in between, these v-brakes will stop you.
At first sight of the Opia’s motor, my thoughts were that it was tiny! I was skeptical about its performance, especially on the hills but its great! It’s real zippy. One thing that helps, and probably with climbing as well is the road tyres. These are thinner, giving us a smooth and low friction roll. Less friction means less work, and less work means less effort to get up hills. Also having the smaller wheels at 20” gave me a very responsive and agile ride.
Although the bike is small, the Opia’s design has been done really well to cater to all sizes. It held me in a comfortable position, and with adjustable seat and handlebars I could tailor this e-bike to fit me. The seat didn’t give me any pain and I rode around 4-5km each session. I think it’s very fitting for this bike because anything smaller and it would be uncomfortable and anything larger would just be too big and defeat the purpose of a mobile bike.
With a fixie design, you can expect this e-bike to be pretty rough on harsh surfaces. So if you are looking at this bike, know your route. If it requires some off road, or has a number of bumps and drops. I’ll probably reconsider the route or bike with front suspension at least. This is all just a sacrifice that needs to be made for efficiency which I think it’s worth it in a situation like this. Keeps costs low and makes the ride easier, which is what we need.
Diving into a bit more depth of the mechanics of the bike, the Opia will give you a pleasant ride. It’s smooth on the road with seamless shifting from the thumb shifter. I don’t think you could ask for anything more than this drivetrain for simple commuting. I found I sat in the 5th and 6th gear most of the time and let the electric motor start up for me. This allowed me to reach cruising speeds quick without having to change the gears too often.
For those who think numbers speak louder than words, you can find the E-Biking Now dyno results for the Opia below.
The Opia really showed its performance here, with a peak torque of 47Nm the Opia possesses a hub on the higher end of street legal motors. This explains the zippy ride I experienced that allowed me to start in high gears and use the motor to start me up. As usual, the power peaked at 351W. This is generally the figure we’d expect from street legal motors.
So how did it stack up to my standards? Pretty good. Will it get you to work? Yes. Is it street legal? Yes. The bike is good, and it gets the job done as cheap and efficiently as possible. With USB charging, and a lightweight frame and flexible design to cater to riders of all heights and sizes. I can see this being a popular budget portable commuter.
There are some changes or preferences I would have liked to see which include an addition of a rear rack as standard. An e-bike like this would benefit greatly with a bike rack. Riders could hold their belongings or their groceries if they go shopping. Also an LCD meter would’ve been nice and the ability to turn off pedal assistance while the bike was on. Other than that, the bike will stand up to your tasks and get you from point A to B in minimal fashion. You can find the full specifications below*
