Review of the TENWAYS CGO600: The e-bike that does everything it can to not look like an e-bike
There are e-bikes that, when you pick them up, make you think right away: “Yeah, that makes sense.” A heavy machine. Motor inside, battery inside, twenty kilos. The TENWAYS CGO600 tells a completely different story. You pick it up, and for a moment, something seems off. Fifteen kilograms, according to the manufacturer. Sixteen point three in practice, in size L, with lights and a kickstand. That’s less than most urban e-bikes you’ll find at any bike shop.
The CGO600 does everything it can to avoid looking like an e-bike. No bulky frame, no screen cluttered with unnecessary information, no motor that starts humming to announce its presence. Just a slim down tube, a discreet hub motor, and a belt drive—without the typical hum of a Bosch system. So… what kind of e-bike is it really?

Key findings
- The torque sensor combined with the carbon belt delivers one of the smoothest and quietest riding experiences I’ve ever had in this price range.
- The non-removable battery isn't just a design choice—it's a real limitation. If you don't have an outlet near your bike, you should think this through carefully before buying.
- The single-speed setup makes it a true city bike: ideal for short, flat daily commutes, but don't expect it to handle anything more than that.

On the road: where it really shines
I have a soft spot for torque sensors. Not because it’s a fancy technical term, but because you can feel the difference right away. A cadence sensor simply detects that you’re pedaling and activates the motor. Sometimes it’s a bit abrupt, as if the bike had its own idea of when you need help.
A torque sensor measures the force you apply to the pedals and adjusts the assistance accordingly.
The CGO600 uses the Mivice S200, and it does its job very well. Really very well. The harder you pedal, the more the bike helps you. When you slow down, the assistance decreases as well. There’s no sudden jerk when you start moving, and no jolts when the assistance kicks in.
The Mivice M070 motor, delivering 40 Nm of torque in the rear hub, is virtually silent. The carbon belt is just as quiet. Together, they create a bike that goes almost unnoticed in the city.
For me, this is the CGO600’s strongest selling point: it gives urban cyclists a sense of control that many heavier—and sometimes more expensive—systems don’t automatically provide.
A Bosch Performance Line motor delivers more torque and more options. But is it smoother and quieter? Not necessarily. And that’s remarkable for a bike in this price range.
Where it reaches its limits (and this is just as important)
A single-speed setup might seem like a stylistic choice. Sometimes it is. On the CGO600, however, it’s primarily the technical result of a design concept aimed at keeping the bike as light and simple as possible—and that has its consequences.
On flat pavement at speeds up to 25 km/h, the drivetrain works perfectly. Above that, the cadence quickly increases and becomes less comfortable. And in more challenging conditions—headwinds, gradients steeper than 5%, or a heavy load—you can feel the motor quickly reaching its limits.
There are no lower gears to shift down to. There is no extra torque to compensate.
When climbing, this system simply doesn't perform as well as a Shimano Steps or a Bosch motor paired with a derailleur.
In my opinion, the non-removable battery is the biggest practical drawback of this bike. TENWAYS claims a range of 70 km; in reality, it’s closer to 40 km under normal use.
For a daily round-trip commute of 20 km, that’s enough. But the problem is charging. The battery is built into the down tube, so you have to charge the entire bike.
If you live in an apartment, if your bike is stored in a shared area, or if there isn’t a power outlet nearby, this is something you really need to plan for.
Solid Build Quality, Variable Performance, and Why It Matters
The build quality is better than you might expect at this price point. The tubes are slim, the overall design is clean, and nothing gives away its affordable price point.
The service, however, is a different story. On Trustpilot, reviews are mixed: some cyclists have ridden over 12,000 km without any issues, while others report engine problems shortly after the warranty expires, difficult communication, or disappointing parts.
TENWAYS covers the cost of repairs under warranty through partner repair shops, but only with prior authorization. Not retroactively.
For this reason, I think it makes sense to consider a refurbished model. A CGO600 purchased through Upway technically inspected, refurbished less expensive than new.
With a brand whose direct service can sometimes be unreliable, this not only saves money but also provides an extra layer of security.
My verdict
The TENWAYS CGO600 is a good bike, but it’s suited to a very specific type of rider. So specific, in fact, that I’d rather not recommend it without qualification.
If you live in the city, ride 30 to 40 km a day on flat terrain, and are looking for a lightweight, quiet, and virtually maintenance-free e-bike that feels like a traditional bike with a little electric boost, then this is one of the best options in its class. The riding experience impressed me more than I would have expected for this price.
But if you're looking for more versatility, a removable battery, or a bike that can easily handle rides outside the city, you're better off looking elsewhere—for example, a Gazelle Orange C7+, a Batavus Finez, or a Kalkhoff Image 3.
Bikes that demand more, but also promise more.
The CGO600 isn't for everyone. But for those it's designed for, it does exactly what it promises.
FAQ
What kind of battery life can you expect from the CGO600?
TENWAYS claims a range of 70 km, but in practice you’ll get closer to 40 km under normal conditions. For a round-trip commute of about 20 km, that’s sufficient. If you regularly ride longer distances or often ride into the wind, this isn’t the most reliable bike.
Is the battery on the TENWAYS CGO600 removable?
No. The battery is built into the down tube. The bike charges directly using the included charger. For people who don’t have an outlet near where they park, this is an important factor to consider.
Is the CGO600 suitable for climbing?
It handles slopes of up to about 5% just fine. Beyond that, you start to feel the limitations of the design: no gears, limited torque, and a small battery. For flat, urban use, it’s perfect. For hilly terrain or very steep bridges, it’s not the ideal choice.
Why consider a refurbished CGO600 refurbished Upway
Because the quality of TENWAYS bikes can vary. The technical inspection and refurbishment performed by Upway greater peace of mind at a lower price than new. You don’t have to worry about minor scratches, and you receive a bike that’s been thoroughly inspected before delivery.
