Tenways CGO600 Pro E-Bike Review, 2023 | Electric Bike Report

Before examining the results of our Range Test, which you can read more about in the graphic above, it’s worth noting that the Tenways CGO600 Pro includes a few different specs between the US and EU versions of the bike. In the EU, the 350W rear hub motor I mentioned in the previous section is instead a 250W unit. The bike’s top speeds are also different, and both of those changes affect the bike’s range.

In the EU, the CGO600 Pro has a range of up to 100km or 62 miles, but in the US (where we are located), this is reduced to 53 miles or 85km. We tested the US version of the bike using its PAS 1 and PAS 3 settings, so I will compare our results accordingly.

With maximum assistance (PAS 3), we traveled just over 33 miles. In its lowest setting, we managed 46 miles in PAS 1. This minimum-assistance result is most relevant for comparison purposes, and despite seeming underwhelming when looking at Tenways’ advertised range, we’re completely satisfied with it. Let’s look at the reasons why:

Both versions of the CGO600 Pro use the same 36V, 10 amp-hour (Ah) battery with a resulting 360 watt-hours (Wh) of capacity. We talk more about the relationship between batteries and the motors they are paired with in our guide to e-bike batteriesbut we typically like to see a 1:1 ratio between battery watt-hours and motor watts. If an e-bike has this characteristic, it should be able travel in its max-assist mode for roughly an hour. We were able to travel for two!

Additionally, range estimates are typically made with only flat ground in mind (and other “ideal” conditions like weather); our test paths have elevation changes that reflect real-world conditions. To account for variability, we build in some flexibility, and the results of this test are well within our margins of error.

Finally, the fact that the CGO600 Pro has a torque sensor means that it’s naturally going to be more efficient than an e-bike with a cadence sensor. We talk more about sensor types in our guide to e-bike hub motorsbut torque sensors require their rider to put in some effort, so the motor and rider are dividing up the work. As such, e-bikes with torque sensors are able to cover more ground because they draw less battery power.

All of that is to say that the bike’s range is fantastic for its specs; when compared to similar e-bikes we’ve tested, the CGO600 Pro is at or near the top of the list! Considering the bike’s effective power in PAS 1, we think it’s entirely practical to keep it in that setting most of the time. This will allow riders to get the most possible distance from the bike’s 350W motor and 360Wh battery!
